Question: [151]
On GitHub.com, what do Copilot code reviews and PR summaries provide?

Options:
A. Automatically approves and merges pull requests without human review.
B. AI review suggestions and natural-language summaries of changes
C. Formal license validation and legal sign-off for all dependencies.
D. Only low-level static analysis warnings without any natural-language context.

Correct Answer(s): B

Explanation:
On GitHub.com, Copilot code reviews and PR summaries provide AI-generated natural-language summaries of the changes in a pull request and suggested review comments that highlight potential issues or discussion points. These features are designed to help reviewers quickly understand what changed and where to focus their attention. They do not auto-approve or merge PRs, perform legal or licensing validation, or replace branch protections and required checks your existing review and governance mechanisms remain in full control.

Tips and Tricks:

• Use PR summaries to quickly orient yourself to large or complex pull requests before drilling into individual files.
• Treat Copilot’s suggested comments as drafts or starting points, and always read the diff and run tests as needed before approving.
• Keep branch protections, required reviewers, and CI checks enabled; Copilot’s suggestions are there to augment your process, not replace it.

Important

Copilot on GitHub.com is a review assistant, not an auto-approver. It can summarize changes and propose comments, but human reviewers and branch protections remain the gatekeepers for code quality, compliance, and merge decisions.

Correct and Wrong:
The correct option is the only one that accurately describes Copilot’s role on GitHub.com: providing AI-generated review suggestions and natural-language summaries of changes to speed human review. The other options incorrectly claim it auto-approves and merges PRs, performs legal/license sign-off, or only surfaces raw static analysis without summaries, none of which matches the documented behavior.

Question: [152]
How does Copilot handle suggestions that exactly match long segments of public code?

Options:
A. Blocks any suggestion that resembles public code, regardless of length or settings.
B. Shows suggestions that match public code but only adds links to the original repositories, without blocking.
C. Uses duplication-detection filters to block long exact matches
D. Relies solely on manual code review to detect and remove duplicated public code.

Correct Answer(s): C

Explanation:
GitHub Copilot uses a duplication-detection filter (exposed via the “suggestions matching public code” setting) to check each suggestion and its surrounding context, about 150 characters, against an index of public GitHub code. When blocking is enabled and Copilot finds a long exact or near-exact match, it suppresses the suggestion instead of showing it to the user. This reduces the chance of generating long verbatim segments of public code while still allowing shorter or non-matching suggestions.

Tips and Tricks:

• Treat long exact (≈150+ characters) matches to public code as the trigger for the duplication-detection / suggestions matching public code filter when blocking is enabled.
• Remember the filter is length- and match-based, not a license engine; it doesn’t reason about license compatibility, it just blocks long matches against public code.
• Use code referencing to control behavior for similar-but-not-exact suggestions when matches are allowed, and configure blocking when your policy forbids matching public code.

Important

The duplication-detection filter is about blocking long exact or near-exact matches to public code, typically around 150+ characters, while code referencing is about showing references or blocking similar-but-not-exact code. When an exam stem mentions “block long exact matches”, it’s pointing to the duplication-detection filter, not code referencing or content exclusion.

Correct and Wrong:
The correct option is the only one that matches the documented behavior: Copilot uses a filter to block long exact (or near-exact) matches to public code when blocking is enabled. The other options either claim Copilot always blocks anything that resembles public code, only ever shows links without blocking, or relies purely on human review, all of which ignore the specific length-based automated filter described in the docs.

Question: [153]
How can Copilot assist with unit testing?

Options:
A. By automatically generating test functions from code definitions
B. By running your unit test suite automatically in your CI/CD pipeline
C. By replacing QA engineers and manual testing processes
D. By creating and managing isolated test environments in the cloud

Correct Answer(s): A

Explanation:
Copilot assists with unit testing primarily by generating test functions and scaffolds from your existing code and prompts. In supported IDEs and Copilot Chat, you can ask it to generate unit tests for a function, file, or selection, and it will propose test methods, assertions, and edge cases that you then review, refine, and run using your normal test runner and CI/CD pipeline. Copilot does not execute tests, manage test runs, or provision environments, it focuses on producing test code.

Tips and Tricks:

• Use explicit prompts like “Generate unit tests for this function using <framework>” and target the relevant file or selection.
• Specify framework, assertion style, and important edge cases (nulls, boundaries, error paths) to improve test quality.
• Treat generated tests as a starting point: refactor, deduplicate, and run them locally or in CI to validate behavior.

Important

Copilot helps you write tests faster, but you are still responsible for reviewing, running, and maintaining them. Exams will emphasize that Copilot generates test code, not that it runs or replaces your testing pipeline.

Correct and Wrong:
The correct option is the only one that reflects Copilot’s documented role: generating unit tests from your code and prompts. The other options incorrectly claim Copilot runs your test suite, replaces QA, or manages environments, which remain responsibilities of your tooling and team.

Question: [154]
Which Copilot plan provides enterprise proxy support for secure environments?

Options:
A. Copilot Free
B. Copilot Individual
C. Copilot Business
D. Copilot Enterprise

Correct Answer(s): D

Explanation:
Copilot Enterprise is the enterprise-tier plan for GitHub Enterprise Cloud organizations. Enterprise owners can configure subscription-based network routing and proxy/allowlisting so that only approved Copilot endpoints are reachable, and combine this with Enterprise features such as audit logs, identity integration, and compliance controls. While enterprise network access controls can govern traffic to both Copilot Business and Copilot Enterprise, exam stems that highlight “enterprise proxy support for secure environments” are targeting Copilot Enterprise as the correct plan.

Tips and Tricks:

• Think of Copilot Business as providing org-level governance (seats, policies, content exclusion, usage), and Copilot Enterprise as adding enterprise identity, compliance, and advanced network routing/proxy scenarios.
• When a question mentions corporate proxy/allowlisting plus enterprise governance or compliance, choose Copilot Enterprise rather than Business or Individual/Free.
• Remember that proxy and firewall configuration is handled at the enterprise/network layer, not inside the Individual/Free plans themselves.

Important

For exams, “enterprise proxy/allowlisting + advanced compliance” is your Copilot Enterprise signal. Business covers org governance, but Enterprise is where you combine those network controls with enterprise-grade identity, audit, and compliance.

Correct and Wrong:
The correct option is the only one that aligns enterprise-grade governance with network access controls in secure environments, Copilot Enterprise for GHEC orgs. The other options either have no org/enterprise controls (Free/Individual) or stop at org-level governance without the full enterprise compliance posture the stem implies (Business).

Question: [155]
On which surfaces is Copilot Chat available today? (Choose all that apply.)

Options:
A. GitHub.com
B. Visual Studio Code
C. Visual Studio
D. JetBrains IDEs
E. Eclipse
F. Xcode
G. GitHub Mobile
H. Windows Terminal
I. GitHub Desktop

Correct Answer(s): A, B, C, D, E, F, G, H

Explanation:
Copilot Chat runs on multiple surfaces: the GitHub website, GitHub Mobile, major IDEs (including Visual Studio Code, Visual Studio, JetBrains IDEs, Eclipse, and Xcode), and Windows Terminal. These experiences share the same Copilot service but are optimized for different workflows (browser, IDE, mobile, CLI). GitHub Desktop is not listed as a supported Copilot Chat surface in official documentation and should be treated as a distractor.

Tips and Tricks:

• Map browser scenarios to GitHub.com, editor integration to the listed IDEs, on-the-go usage to GitHub Mobile, and CLI workflows to Windows Terminal.
• Remember that GitHub Desktop is commonly used as a distractor; it does not host Copilot Chat.
• Plan and policy still matter: some Enterprise-only enhancements (like repository-aware chat on GitHub.com) require Copilot Enterprise, but the core Chat surfaces remain the same.

Important

Separate “Where can Chat run?” (GitHub.com, supported IDEs, GitHub Mobile, Windows Terminal) from “Which plan unlocks which enhancement?”. The list of surfaces stays stable; features per surface can change by plan and org policy.

Correct and Wrong:
The correct set of options (A, B, C, D, E, F, G, H) matches the official list of Copilot Chat surfaces. GitHub Desktop (I) is incorrect because it is not a documented Copilot Chat surface and is included to test whether you know the supported environments.

Question: [156]
Is GitHub Copilot supported on GitHub Enterprise Server (GHES)?

Options:
A. Yes, Copilot runs entirely on-premises inside your GHES instance.
B. No, Copilot requires the cloud service; GHES is not supported
C. Yes, but only Copilot Chat is supported on GHES.
D. Yes, with a fully self-hosted Copilot model inside your data center.

Correct Answer(s): B

Explanation:
GitHub Copilot is a cloud-hosted service and is not supported on GitHub Enterprise Server (GHES). To use Copilot, developers must sign in with a GitHub.com or GitHub Enterprise Cloud account, and Copilot’s inference and policy services run in the cloud. There is no supported configuration where Copilot runs entirely on-prem, as a GHES-only Chat experience, or as a fully self-hosted model.

Tips and Tricks:

• Treat “GHES-only,” “air-gapped,” or “on-prem-only” scenarios as Copilot not supported.
• Copilot Enterprise specifically relies on GitHub Enterprise Cloud (GHEC), not GHES.
• Even when used from IDEs, Copilot extensions connect to the Copilot cloud service, not directly to GHES.

Important

Deployment posture matters: GHES-only = no Copilot. Any stem that implies a fully on-prem, offline, or air-gapped GitHub deployment should push you toward “Copilot is not supported” as the correct answer.

Correct and Wrong:
The correct option is the only one that matches the documentation: Copilot is not available on GHES and requires the cloud service. The other options incorrectly suggest on-prem, GHES-only Chat, or self-hosted Copilot deployments, which GitHub does not support.

Question: [157]
What can Copilot Chat in the CLI help you do?

Options:
A. Draft and explain shell and Git commands and their flags
B. Execute terminal commands automatically without your confirmation
C. Completely replace the need for shell help and man pages
D. Automatically provision and configure cloud environments from the CLI

Correct Answer(s): A

Explanation:
Copilot Chat in the CLI (for example, in Windows Terminal) can suggest, draft, and explain shell and Git commands, including what the flags and options do. It helps you design and understand commands before you run them. Copilot does not automatically execute these commands, replace traditional documentation, or orchestrate cloud environment provisioning; you remain responsible for validating and running commands yourself.

Tips and Tricks:

• Ask questions like “What command would do X?” or “Explain this git command” and then carefully review the answer before executing anything.
• Prefer non-destructive examples (for example, adding --dry-run or echoing the command) when trying suggestions from Copilot.
• For deeper reasoning about code, tests, or multi-file context, switch to IDE Copilot Chat, where file and selection context is richer.

Important

Copilot in the CLI is about command guidance, not unattended execution. You must still inspect, approve, and run commands using your normal safety practices.

Correct and Wrong:
The correct option is the only one that reflects Copilot’s role in the CLI: drafting and explaining shell/Git commands and flags. The other options overstate its capabilities by implying auto-execution, full replacement of documentation, or automated environment provisioning, none of which Copilot actually does.

Question: [158]
Across environments, what’s the right way to think about inline suggestions vs. Chat?

Options:
A. Inline runs only in browsers, while Chat runs only inside IDEs.
B. Inline = cursor-local completions; Chat = multi-turn reasoning with selectable context (files/regions)
C. Chat always writes code straight to the repository without user review.
D. Inline is deprecated and disabled once Chat is turned on.

Correct Answer(s): B

Explanation:
Inline suggestions are cursor-local completions that appear directly in your editor as you type, offering single-line or small block suggestions you can accept, reject, or modify. Copilot Chat is a multi-turn conversational interface on GitHub.com and in supported IDEs where you can ask for explanations, refactors, tests, or new code using file, selection, or repository context. In both cases, generated code only affects your working copy until you explicitly add, commit, and push it.

Tips and Tricks:

• Use inline suggestions for quick, local edits like completing lines, small functions, or obvious boilerplate.
• Use Chat for deeper reasoning tasks: explaining code, planning refactors, generating tests, or designing new modules across multiple files.
• Remember that accepting code from either inline or Chat still goes through your normal git add/commit/PR process, including tests and reviews.

Important

Think “inline = quick completion, Chat = structured reasoning.” Neither bypasses your version control, tests, or review policies, you stay in control of what actually lands in the repository.

Correct and Wrong:
The correct option is the only one that captures the conceptual distinction: inline as cursor-local completions and Chat as multi-turn reasoning with selectable context. The other options misstate surface limitations, claim that Chat writes directly to the repo, or suggest inline is deprecated, none of which are accurate.

Question: [159]
Do content exclusion policies apply across all Copilot surfaces?

Options:
A. No, content exclusion only applies when using Copilot in Visual Studio Code.
B. Yes, content exclusion defines the input context boundary for Copilot across supported surfaces
C. No, it only affects Copilot Chat on GitHub.com, not IDEs.
D. No, it only applies in JetBrains IDEs and not on other clients.

Correct Answer(s): B

Explanation:
Content exclusion lets administrators define which repositories, directories, file types, or patterns Copilot is allowed to use as context. Enforcement happens in the Copilot service, so the same exclusion rules apply wherever Copilot is used with that organization’s content whether in IDEs, GitHub.com, or other supported chat/suggestion surfaces. It is not limited to a single IDE or to GitHub.com only; it acts as a global input boundary for that org/enterprise’s Copilot usage.

Tips and Tricks:

• Use content exclusion at the org/enterprise level to shield sensitive content (secrets, regulated data, proprietary algorithms) from being used as Copilot input.
• Combine content exclusion (inputs) with code referencing and duplication filters (outputs) to control both what Copilot can see and what it can suggest.
• Remember that Individual/Free plans do not expose these admin-level exclusion controls; they are available to Business and Enterprise organizations.

Important

Treat content exclusion as a global input fence around your organization’s code: once excluded, that content is not used as context on any Copilot surface associated with that org or enterprise.

Correct and Wrong:
The correct option is the only one that reflects content exclusion as a service-wide input boundary applied across Copilot surfaces that use your org’s content. The other options incorrectly restrict the effect to one client (VS Code, JetBrains, or GitHub.com only), which does not match how the feature is enforced.

Question: [160]
What Copilot plan offers AI-powered code completions for free, but with limited features compared to paid plans?

Options:
A. Copilot Free
B. Copilot Individual (Pro/Pro+), with full paid features for one developer
C. Copilot Business, with org-level governance and reporting
D. Copilot Enterprise, with enterprise integrations and network controls

Correct Answer(s): A

Explanation:
Copilot Free provides no-cost access to core AI-powered code completions for individuals, with usage limits and no organizational governance or enterprise integrations. Paid plans like Copilot Individual, Copilot Business, and Copilot Enterprise add capabilities such as richer Copilot Chat experiences, org/enterprise policies, usage reporting, and advanced integrations that are not part of the Free tier.

Tips and Tricks:

• Think of Copilot Free as a limited personal tier for trying AI completions, not for team or enterprise governance.
• When a stem mentions org policy, usage reporting, or enterprise features, the answer cannot be Copilot Free.
• Education and maintainer benefits map you to Pro/Pro+, which is still a paid-level feature set, not the Free plan.

Important

Free ≠ Pro: Copilot Free gives basic, personal access with limitations and no org/enterprise controls. Any question about governance, reporting, or enterprise integration pushes you to Business or Enterprise, not Free.

Correct and Wrong:
The correct option is the only one that matches “free but limited AI-powered completions” without governance. The other options are all paid plans with additional capabilities like org/enterprise management, so they do not satisfy the “for free, with limited features” condition.

Question: [161]
Which Copilot plan provides organizational visibility into usage metrics but does not include enterprise-grade compliance?

Options:
A. Copilot Individual (Pro/Pro+), with no org-wide usage reporting
B. Copilot Business
C. Copilot Enterprise, with enterprise-grade compliance integrations
D. Copilot Free, with no admin visibility

Correct Answer(s): B

Explanation:
Copilot Business gives organization owners visibility into usage metrics, along with seat management and policy controls like content exclusion. It is aimed at organizations that need to manage and understand Copilot usage but do not require the full enterprise identity, compliance, and network integrations that come with Copilot Enterprise.

Tips and Tricks:

• “Usage metrics / usage reporting / manage seats” without explicit SSO or compliance language ⇒ Copilot Business.
• “SSO, enterprise identity, audit, advanced compliance” ⇒ Copilot Enterprise.
• Individual and Free tiers do not offer any org-level usage reporting or centralized management.

Important

When a stem emphasizes organizational visibility into usage but says nothing about enterprise compliance or identity, the exam target is Copilot Business, not Enterprise.

Correct and Wrong:
The correct option is the only one that aligns with org-level usage reporting without enterprise compliance integrations. Enterprise goes beyond usage visibility into full enterprise identity and governance; Individual and Free have no admin reporting at all.

Question: [162]
Which Copilot plan gives organizations control over which repositories and code Copilot can access?

Options:
A. Copilot Free, with no org-level repository controls
B. Copilot Individual (Pro/Pro+), with only personal settings
C. Copilot Business
D. Copilot Enterprise, which builds on Business with enterprise integrations

Correct Answer(s): C

Explanation:
Copilot Business introduces organization-level controls such as content exclusion and Copilot policies that let org owners decide which repositories, directories, file types, and patterns Copilot can use as input context. These controls also exist at the Enterprise level, but Business is the first plan where organizations gain centralized control over Copilot’s access to their code. Individual and Free plans only allow personal configuration and do not provide org-wide repository governance.

Tips and Tricks:

• Map “which repos/code can Copilot access?” to content exclusion + org policies, which start at Copilot Business and extend to Enterprise.
• Understand that Enterprise can enforce or override org policies, but the baseline org repository control tier is Business.
• Individual/Free configuration is confined to personal scope; it cannot govern org-wide repository access.

Important

When a question focuses on organizations controlling which repositories or code Copilot can access, start with Business (or higher). Only escalate to Enterprise if the stem explicitly adds enterprise identity or compliance requirements.

Correct and Wrong:
The correct option is the only one that reflects the starting plan where organizations get central control over Copilot’s repository access. Enterprise also has these controls but adds extra enterprise features; Free and Individual lack any org-wide repository access controls.

Question: [163]
Which Copilot plan is most appropriate for developers who want Copilot Chat and code completion but no organizational management features?

Options:
A. Copilot Free, with limited features and no full Chat experience
B. Copilot Individual (Pro/Pro+)
C. Copilot Business, which adds org-level management and reporting
D. Copilot Enterprise, which adds enterprise identity and compliance

Correct Answer(s): B

Explanation:
Copilot Individual (Pro/Pro+) is designed for single developers who want Copilot Chat and code completions but do not need organizational management features such as seat assignment, usage reporting, or centralized policies. Copilot Business and Copilot Enterprise target organizations and enterprises that require those governance and management capabilities. Copilot Free is more limited and does not provide the full set of features found in the paid Individual plans.

Tips and Tricks:

• If the stem describes a solo developer or personal use with Chat and completions and explicitly says there is no need for org management, the answer is Copilot Individual (Pro/Pro+).
• Any mention of org policies, admin controls, or usage reporting means you should look at Business or Enterprise, not the Individual plan.
• Education and open-source maintainer benefits that grant Pro still map to the Individual plan line.

Important

Distinguish between developer features (Chat, completions) and governance features (policies, reporting). Individual covers the former for one person; Business/Enterprise add the latter for teams and organizations.

Correct and Wrong:
The correct option is the only one that matches “Chat + completions, no organizational management”. Free is too limited, and both Business and Enterprise introduce org/enterprise features that the stem explicitly excludes.

Question: [164]
Is Copilot Enterprise included with GitHub Enterprise Cloud (GHEC) at no additional cost?

Options:
A. No, Copilot Enterprise is a separate paid subscription available to GHEC orgs
B. Yes, it’s bundled for free with GHEC

Correct Answer(s): A

Explanation:
Copilot Enterprise is not automatically included with GitHub Enterprise Cloud (GHEC). It is a separate paid subscription that GHEC organizations can choose to purchase and assign. Enterprise owners decide whether to subscribe each organization to Copilot Business or Copilot Enterprise, and Copilot Enterprise usage is billed on top of the core GHEC subscription. Being a GHEC org means you are eligible to buy Copilot Enterprise, not that it is free.

Tips and Tricks:

• Read “available to GHEC orgs” as eligibility, not inclusion.
• Different organizations in the same enterprise can choose Business or Enterprise as needed.
• Copilot consumption (including premium requests) is part of your Copilot plan billing, not automatically covered by GHEC base pricing.

Important

Treat “included with GHEC” as a trap. Copilot Enterprise is eligible for GHEC organizations but is not bundled at no additional cost.

Correct and Wrong:
The correct option is the only one that reflects Copilot Enterprise as a separate paid SKU that sits on top of GHEC. The incorrect option wrongly claims that Copilot Enterprise is bundled free with GHEC, which is explicitly contradicted by GitHub’s plan documentation.

Question: [165]
Which Copilot feature is particularly useful for exploring unfamiliar APIs?

Options:
A. Copilot Chat for natural-language questions
B. Payroll automation workflows
C. GitHub Actions for CI/CD pipelines
D. Enterprise proxy configuration for network routing

Correct Answer(s): A

Explanation:
Copilot Chat is especially useful when working with unfamiliar APIs because you can ask natural-language questions like “Explain how to call this API” or “Generate example code using this client library.” Chat can generate usage examples, explain parameters and responses, and help troubleshoot errors, which accelerates learning compared to reading documentation alone.

Tips and Tricks:

• Ask Copilot Chat to generate example code for a named API or client library, then refine it with follow-up prompts.
• Include API version, language, and framework in your prompt to reduce hallucinations and get more accurate samples.
• Always validate example code against official API documentation and test it with real calls before production use.

Important

Copilot Chat can accelerate discovery and experimentation with unfamiliar APIs, but it does not guarantee correctness you must still cross-check with official docs and tests.

Correct and Wrong:
The correct option is the only one that provides interactive, natural-language guidance for exploring unfamiliar APIs. Payroll automation, GitHub Actions, and enterprise proxy configuration are unrelated capabilities and do not help directly with understanding or learning an API surface.

Question: [166]
Which Copilot plan integrates with enterprise authentication and SSO?

Options:
A. Copilot Free, with no enterprise identity integration
B. Copilot Individual (Pro/Pro+), with personal GitHub authentication only
C. Copilot Business, with org governance but no dedicated enterprise identity features
D. Copilot Enterprise

Correct Answer(s): D

Explanation:
Copilot Enterprise is designed for GitHub Enterprise Cloud organizations that use enterprise authentication (SSO) and identity providers. While SSO itself is configured at the GitHub Enterprise Cloud / organization level, Copilot Enterprise is the Copilot plan that aligns with enterprise identity, governance, and compliance scenarios, integrating with those SSO setups to control and audit Copilot usage across the enterprise. Free and Individual plans have no enterprise identity story, and Copilot Business stops at org-level governance without the full enterprise posture.

Tips and Tricks:

• When a question mentions SSO, enterprise identity providers, or enterprise-wide authentication, pick Copilot Enterprise.
• Remember that SSO is a GHEC feature; Copilot Enterprise is the Copilot SKU built to operate in that enterprise identity context.
• Copilot Business provides org governance but not the full set of enterprise identity/compliance integrations hinted at by SSO-focused stems.

Important

Treat SSO and enterprise identity as strong Copilot Enterprise signals in exam questions, especially when they appear alongside audit or compliance requirements.

Correct and Wrong:
The correct option is the only one that corresponds to the enterprise-tier Copilot plan that fits into an SSO-enabled enterprise identity environment. Free and Individual are personal tiers, and Business does not deliver the enterprise identity/compliance integration the stem implies.

Question: [167]
Which Copilot plan allows organization admins to set policy for code suggestions?

Options:
A. Copilot Individual (Pro/Pro+), where only personal preferences apply
B. Copilot Business
C. Copilot Enterprise, which can enforce or delegate policies across organizations
D. Copilot Free, with no policy management

Correct Answer(s): B

Explanation:
Copilot Business is the first Copilot plan where organization admins (org owners) can configure Copilot policies that control feature and model behavior for members, for example, code referencing posture, duplication filtering, and certain privacy settings. Copilot Enterprise allows enterprise owners to enforce these policies across organizations or delegate them, but the question focuses specifically on “organization admins,” making Business the nearest correct answer. Individual and Free plans do not provide any org-level policy management.

Tips and Tricks:

• When a stem mentions “organization admins” configuring Copilot policies, think Copilot Business (or higher).
• Enterprise adds an extra enforcement layer across orgs, but org-level policy configuration begins at Business.
• User-level settings on Individual/Free accounts are always overridden by enforced org/enterprise policies.

Important

Remember the policy hierarchy: Enterprise (if enforced) → Organization → User. For questions about org admins setting policies, Copilot Business is the expected answer unless the stem clearly escalates to enterprise-wide enforcement.

Correct and Wrong:
The correct option is the only one that represents the first plan where organization admins can set Copilot policies. Enterprise also supports policy management but is not required just to let org admins configure them. Individual and Free lack any org-level policy controls.

Question: [168]
Which Copilot plan offers enterprise support SLAs?

Options:
A. Copilot Free, with community-level help only
B. Copilot Individual (Pro/Pro+), with standard individual support
C. Copilot Business, with org controls but no enterprise support program
D. Copilot Enterprise

Correct Answer(s): D

Explanation:
Enterprise support SLAs come from your GitHub Enterprise support agreement, not from the Copilot SKU alone. However, in the context of Copilot plans, Copilot Enterprise is the plan intended to be used with GitHub Enterprise Cloud and its support framework. Free, Individual, and Business plans do not include enterprise-grade support SLAs; those SLA guarantees apply when you are using Copilot Enterprise under a GitHub Enterprise account with the appropriate support level.

Tips and Tricks:

• Treat “enterprise support SLAs” as a strong hint that the scenario involves a GitHub Enterprise account using Copilot Enterprise.
• Remember that the support SLA itself is tied to your Enterprise support contract, but Copilot Enterprise is the Copilot plan that participates in that context.
• Copilot Business and Individual do not carry expectations of enterprise-grade support SLAs.

Important

SLAs are governed by your GitHub Enterprise support plan, but in exam questions, “enterprise support SLAs” maps to Copilot Enterprise, not to Business or Individual.

Correct and Wrong:
The correct option is the only one that fits the enterprise-level support context. The other plans are aimed at individuals or orgs without tying into the enterprise support program that offers formal SLAs.

Question: [169]
Which Copilot plan is intended for teams that need usage reporting and management but not enterprise integrations?

Options:
A. Copilot Free, with no org reporting or management
B. Copilot Individual (Pro/Pro+), for single users only
C. Copilot Business
D. Copilot Enterprise, which adds enterprise identity and compliance integrations

Correct Answer(s): C

Explanation:
Copilot Business is designed for teams and organizations that need usage reporting, license/seat management, and policy controls (such as content exclusion), but do not require enterprise-level identity, compliance, or network integrations. It gives org admins the ability to manage access and visibility for their organization without stepping up to the full capabilities of Copilot Enterprise.

Tips and Tricks:

• “Usage reporting + manage seats + org policies” but no SSO/audit/compliance ⇒ Copilot Business.
• “Enterprise identity, SSO, audit, advanced compliance, or network routing” ⇒ Copilot Enterprise.
• Free and Individual plans do not offer centralized team/org-level reporting and management.

Important

When a stem says “teams need usage reporting and management but not enterprise integrations,” the correct choice is Copilot Business it’s the governance starter pack without enterprise identity/compliance.

Correct and Wrong:
The correct option is the only one that satisfies team-level usage reporting and management without enterprise integrations. Enterprise overshoots the requirement by adding identity and compliance; Free and Individual undershoot by lacking any org-level reporting or management.

Question: [170]
Which Copilot plan is designed for individual developers who do not need organizational features?

Options:
A. Copilot Free, with limited features and no full Pro experience
B. Copilot Individual (Pro/Pro+)
C. Copilot Business, for organizations that need governance and reporting
D. Copilot Enterprise, for enterprises with identity and compliance requirements

Correct Answer(s): B

Explanation:
Copilot Individual (Pro/Pro+) is intended for single developers who want Copilot’s code completions and Chat but do not need organizational capabilities like seat management, usage reporting, or centralized policies. Copilot Business and Copilot Enterprise are designed for organizations and enterprises, while Copilot Free is a more limited personal tier.

Tips and Tricks:
Use Copilot Individual for personal/dev-box use where you only need developer features.
Move up to Business or Enterprise if you require org-level policies, reporting, or governance.
Remember that education and maintainer benefits generally grant Pro, which is still an Individual plan.

Important

Keep the boundary clear: Individual = developer features, Business/Enterprise = governance and management. If org governance is explicitly out of scope, the correct answer is an Individual plan.

Correct and Wrong:
The correct option is the only one that delivers full-featured Copilot for a single developer without organizational management. Free is too limited, and Business/Enterprise introduce org/enterprise features that the stem explicitly says are not needed.

Question: [171]
Which Copilot plan allows organizations to configure repository-level content exclusions?

Options:
A. Copilot Free, which has no org-level exclusion controls
B. Copilot Individual (Pro/Pro+), which only has personal settings
C. Copilot Business
D. Copilot Enterprise, which can also enforce exclusions across organizations

Correct Answer(s): C

Explanation:
Content exclusion which lets admins define repository-level exclusions (repositories, paths, file types, and patterns) to control what Copilot can use as context is introduced for organizations starting with Copilot Business and is also available in Copilot Enterprise. Because the stem asks which plan allows organizations to configure these exclusions, Copilot Business is the first relevant plan and the exam’s expected answer.

Tips and Tricks:
Associate “content exclusion” and “which repos Copilot can see” with Business/Enterprise, not Free/Individual.
Use Business as the starting tier for org-level exclusions; Enterprise can enforce or override policies across orgs.
Combine content exclusion (inputs) with code referencing (outputs) for full governance.

Important

For exam questions phrased as “organizations configuring repository-level content exclusions”, pick Copilot Business unless the stem explicitly adds enterprise-wide enforcement requirements.

Correct and Wrong:
The correct option is the only one that represents the first plan where orgs get content exclusion controls. Enterprise also includes them but is not required just to configure exclusions; Free and Individual do not provide org-level repo exclusion at all.

Question: [172]
Which Copilot plan is ideal for enterprises requiring integration with enterprise identity providers (SSO)?

Options:
A. Copilot Free, with no enterprise identity integration
B. Copilot Individual (Pro/Pro+), with only personal sign-in
C. Copilot Business, which adds org governance but not enterprise identity providers
D. Copilot Enterprise

Correct Answer(s): D

Explanation:
Copilot Enterprise is tailored for GitHub Enterprise Cloud organizations that integrate GitHub with enterprise identity providers (SSO). While SSO is configured at the GitHub Enterprise/organization level, Copilot Enterprise is the Copilot plan meant for environments with enterprise identity, audit, and compliance requirements, and is the correct choice when SSO and identity providers are central to the scenario.

Tips and Tricks:
Treat “SSO”, “enterprise identity provider”, or “federated identity” as strong hints toward Copilot Enterprise.
Remember that Business focuses on org governance but not the full enterprise identity/compliance stack implied by SSO-focused stems.
Free and Individual tiers only involve standard GitHub user sign-in, not enterprise identity integrations.

Important

Whenever a stem highlights enterprise SSO or identity providers as a requirement, Copilot Enterprise is the Copilot plan that fits that environment.

Correct and Wrong:
The correct option is the only one that matches the enterprise identity + SSO requirement. Business is org-focused but not positioned as the SSO-centric enterprise tier, and Free/Individual have no enterprise identity integration at all.

Question: [173]
How does Copilot help increase developer productivity?

Options:
A. By automating repetitive coding tasks and accelerating prototyping
B. By managing payroll and HR systems for the organization
C. By eliminating the need for IDEs and tooling entirely
D. By automatically generating strategic business plans

Correct Answer(s): A

Explanation:
GitHub Copilot improves developer productivity by automating repetitive coding tasks, generating boilerplate, scaffolding tests, and helping with quick prototyping. It accelerates common tasks like setting up APIs or wiring routine logic, freeing developers to focus on architecture, design, and higher-value work. It does not manage payroll, replace IDEs, or create business plans.

Tips and Tricks:
Use Copilot for boilerplate, scaffolding, and mundane code, and focus your time on core logic and design decisions.
Keep Copilot-driven changes small and testable, and run automated tests frequently.
Treat Copilot suggestions as drafts that you review, refactor, and integrate into your normal workflow.

Important

Productivity gains come from reducing routine work, not skipping tests, reviews, or governance, your usual quality gates still apply.

Correct and Wrong:
The correct option is the only one aligned with Copilot’s documented value: helping with repetitive coding and fast prototyping. The other options describe business operations or unrealistic claims that Copilot does not address.

Question: [174]
What can developers use Copilot for when working with unfamiliar APIs?

Options:
A. Generate example code and speed up learning
B. Automatically produce complete, authoritative documentation for the entire API
C. Remove or uninstall APIs from existing projects
D. Handle licensing or contractual agreements for API usage

Correct Answer(s): A

Explanation:
When working with unfamiliar APIs, developers can use Copilot especially Copilot Chat to generate example code, explore usage patterns, and get explanations of parameters, responses, and error handling. This significantly speeds up learning and experimentation, but must be validated against the API’s official documentation and real-world testing.

Tips and Tricks:
Ask Copilot to “show example usage of <API> in <language/framework>” and iterate with follow-up questions.
Include version info and constraints/allowed endpoints in prompts to reduce hallucinations.
Cross-check Copilot’s examples with the vendor’s official docs and samples before using them in production code.

Important

Copilot helps you learn and experiment with unfamiliar APIs; it does not automatically create official documentation or handle licensing for you.

Correct and Wrong:
The correct option is the only one that reflects Copilot’s realistic role: generating example code and helping you learn. Automatically documenting entire APIs, removing APIs from projects, or managing licenses are not Copilot capabilities.

Question: [175]
Why is it important to validate Copilot’s output for compliance?

Options:
A. To ensure code meets organizational and legal requirements
B. Because Copilot guarantees that all generated code is fully compliant by default
C. To eliminate the need for testing frameworks and quality checks
D. To stop GitHub from training its models on any of your code

Correct Answer(s): A

Explanation:
It is important to validate Copilot’s output because compliance and governance responsibilities remain with your organization, not with Copilot. Validation ensures that generated code aligns with your security, licensing, regulatory, and internal policy requirements. Copilot does not guarantee compliance or replace your existing controls like code review, testing, or license scanning.

Tips and Tricks:
Configure code referencing, duplication filters, and content exclusion to align Copilot behavior with your policies, but still review outputs for compliance.
Keep branch protections, required reviews, security scans, and license checks in your CI/CD pipeline.
Train developers to treat Copilot suggestions as proposals that must pass the same governance checks as any other code.

Important

Copilot assists with generation but does not certify compliance, your organization must validate outputs through its own policy, review, and testing processes.

Correct and Wrong:
The correct option is the only one that acknowledges that compliance is an organizational responsibility and that validating Copilot output ensures it meets legal and policy requirements. The other options either wrongly assume Copilot guarantees compliance, suggest skipping testing, or conflate validation with training behavior.

Question: [176]
How can Copilot help developers write repetitive boilerplate code?

Options:
A. By automatically generating common patterns and structures
B. By manually copying boilerplate from documentation into the codebase
C. By outsourcing repetitive coding tasks to external developers
D. By skipping the need to write any repetitive code at all

Correct Answer(s): A

Explanation:
Copilot can infer and generate boilerplate code such as constructors, handlers, configuration objects, and simple DTOs based on surrounding context and brief natural-language comments. This reduces the time spent on repetitive setup, while still following patterns that are idiomatic to your codebase or ecosystem. Developers remain responsible for reviewing and adapting this boilerplate before committing.

Tips and Tricks:
Use a short comment describing intent, inputs, outputs, and errors so Copilot can propose the right shape of boilerplate.
Ask for minimal, idiomatic examples rather than large blocks to keep generated code focused and readable.
Always compile, run, and test after accepting boilerplate; treat Copilot’s output as a draft that needs verification.

Important

Copilot is best at accelerating routine work, not guaranteeing correctness. Never paste unreviewed boilerplate into production use linters, tests, and code review to validate what it generates.

Correct and Wrong:
The correct option is the only one that reflects Copilot’s ability to generate boilerplate automatically from context and prompts. The other options either describe manual copying, outsourcing, or skipping repetitive code entirely, which are not how Copilot works.

Question: [177]
How does Copilot assist with learning new frameworks or languages?

Options:
A. By providing fully curated tutorials and long-form documentation for every framework
B. By generating code snippets and examples in real time
C. By automatically installing and configuring all required dependencies
D. By blocking unsupported frameworks so you cannot use them

Correct Answer(s): B

Explanation:
Copilot assists with learning new languages and frameworks by generating context-aware code snippets and examples directly in your editor or via Chat. It can show how to use APIs, follow idiomatic patterns, and respond to natural-language questions with runnable fragments, letting you learn by iterating on real code instead of only reading documentation.

Tips and Tricks:
Include the language, framework, and version in your prompt to avoid outdated or deprecated APIs.
Ask Copilot to include error handling and simple tests so that edge cases and failure modes are visible.
Always validate examples against the framework’s official documentation and your team’s coding standards before adopting patterns.

Important

Copilot speeds up learning and experimentation, but it does not replace official docs treat generated examples as starting points, not authoritative guidance.

Correct and Wrong:
The correct option is the only one that describes Copilot’s real-time code example generation. The other options incorrectly suggest that Copilot provides full curated tutorials, manages dependency installation, or blocks frameworks.

Question: [178]
Which scenario demonstrates Copilot helping with testing?

Options:
A. Copilot generates boilerplate unit tests from function definitions or selected code
B. Copilot deploys application code straight to production environments
C. Copilot replaces manual QA by executing exploratory tests on its own
D. Copilot reviews legal contracts for licensing and compliance

Correct Answer(s): A

Explanation:
Copilot helps with testing by scaffolding unit tests based on a function’s signature, selected code, or a natural-language test description. It can suggest test methods, inputs, and basic assertions, allowing developers to focus on refining logic and adding coverage rather than writing every test from scratch.

Tips and Tricks:
Highlight the target function or file and specify the test framework (for example, JUnit, pytest, xUnit) in your prompt.
Ask explicitly for edge cases, negative scenarios, and boundary conditions instead of only happy-path tests.
Keep generated tests small and focused, then run them in your normal test runner as part of the red–green–refactor loop.

Important

Copilot can speed up test creation, but you must still review generated tests and integrate them into your CI and quality gates to ensure meaningful coverage.

Correct and Wrong:
The correct option is the only one that shows Copilot generating test code. The other options incorrectly attribute deployment, full manual QA replacement, or legal review to Copilot.

Question: [179]
Which of the following is NOT a Copilot developer use case?

Options:
A. Generating code snippets and helper functions in your editor
B. Writing inline documentation comments and basic explanations for code
C. Producing marketing slogans and non-technical advertising copy
D. Assisting with unit tests and simple test scaffolds

Correct Answer(s): C

Explanation:
GitHub Copilot is positioned as an AI pair programmer aimed at software development workflows writing and refactoring code, assisting with documentation comments, and helping with tests. Using Copilot to create marketing slogans or non-technical advertising content is outside the intended scope for developer-focused Copilot scenarios.

Tips and Tricks:
Aim Copilot at code, docs, tests, reviews, and PR workflows, where it has the most context and value.
Use Chat for explanations, refactors, and design help; use inline suggestions for snippets and boilerplate.
Avoid mixing non-technical or marketing tasks into exam scenarios they are usually distractors.

Important

Keep your prompts development-focused. Off-scope requests (like marketing copy) tend to produce weaker results and are not part of the intended Copilot exam use cases.

Correct and Wrong:
The correct option is the only one that clearly describes a non-development use case (marketing slogans). The other options fall squarely within Copilot’s core dev-focused usage, such as code generation, documentation comments, and testing assistance.

Question: [180]
Which of the following is a limitation of using Copilot for testing?

Options:
A. Copilot cannot generate any unit test or test-related code at all
B. Generated tests may require developer review and validation
C. Copilot always produces perfectly correct tests with complete coverage
D. Copilot can only write documentation and is unable to assist with tests

Correct Answer(s): B

Explanation:
A key limitation of using Copilot for testing is that generated tests still require human review and validation. Copilot can scaffold tests and suggest assertions, but it does not guarantee logical correctness, edge-case coverage, or alignment with organizational standards. Developers must refine these tests, measure coverage, and ensure they meaningfully validate behavior.

Tips and Tricks:
Add or adjust assertions, fixtures, and test data so they reflect real business behavior and edge cases.
Track coverage and test quality (for example, mutation testing) in your CI pipeline to avoid a false sense of safety.
Use code review to spot weak or superficial tests that might appear correct but do not really exercise logic.

Important

Copilot-generated tests are assistance, not a guarantee they should pass through the same reviews, coverage checks, and quality gates as any other test code.

Correct and Wrong:
The correct option is the only one that acknowledges that Copilot’s outputs require developer review and validation. The other options either understate Copilot’s capabilities (cannot generate tests) or overstate them (guaranteed coverage, only writes docs).
