Microsoft GH-300: GitHub Copilot

Last checked October 22, 2026 against the official Microsoft exam page.

1. Question 1GitHub Copilot fundamentals

   A developer types a function signature and a docstring in the editor, and Copilot suggests the function body as grey text. What feature is this?

   1. ACopilot code review
   2. BDependabot version updates
   3. CInline code completion
   4. DCopilot Workspace planning
   Show answer and explanationHide answer

   Correct answer: C

   Inline suggestions that appear as the developer types are code completions. Code review, workspace planning and Dependabot updates are separate capabilities.

2. Question 2Prompt engineering for GitHub Copilot

   A developer wants a Python function that validates an email address and returns a boolean, with a docstring and unit tests. Which prompt is most likely to produce a useful result?

   1. AWrite some code for the email part of the project and keep it looking properly clean, adding whatever else the application needs
   2. BJust produce something that runs without errors, however it is structured, and do not worry about the details or the expected inputs
   3. CMake it good overall, clean and polished, and tidy up the naming so it reads nicely to whoever opens it later
   4. DA specific request that states the language, expected inputs and outputs, edge cases, and that tests should be included

   Correct answer: D

   Specific prompts with language, inputs, outputs, edge cases and deliverables give Copilot clear targets. Vague prompts produce unpredictable results.

3. Question 3Responsible use of GitHub Copilot

   A developer accepts a Copilot suggestion that uses a library the team has never reviewed. What should happen before merging?

   1. AThe library should be installed in production and its version pinned without a security or licensing review by the team
   2. BThe dependency should be reviewed for licensing, security, and maintenance like any other new dependency
   3. CThe suggestion should be merged immediately because Copilot selected it for this file
   4. DThe dependency should be removed from the lock file so it no longer appears in the audit report or the dependency graph
   Show answer and explanationHide answer

   Correct answer: B

   Suggested dependencies must be vetted like any other dependency, including licensing and security. Merging immediately, installing without review and hiding dependencies all bypass governance.

4. Question 4GitHub Copilot for business administration

   An organization wants to allow Copilot only for approved repositories. Which setting controls this?

   1. AContent exclusion and policy controls for Copilot in the organization settings
   2. BThe user's profile picture and the avatar displayed beside their commits in the activity feed
   3. CThe repository's star count and fork count shown on its landing page
   4. DThe organization's logo, its brand colors, and the favicon used on the public homepage banner
   Show answer and explanationHide answer

   Correct answer: A

   Content exclusion and organization policies control which code and users are covered by Copilot. Stars, logos and profile pictures do not control Copilot access.

5. Question 5GitHub Copilot fundamentals

   Which Copilot experience lets a developer ask natural-language questions about code in the IDE and receive explanations or proposed edits?

   1. ACopilot licensing dashboard
   2. BGitHub Pages
   3. CDependabot alerts
   4. DCopilot Chat
   Show answer and explanationHide answer

   Correct answer: D

   Copilot Chat provides a conversational interface in the IDE for explanations, questions and edit suggestions. The licensing dashboard manages seats, Dependabot alerts dependencies and Pages hosts sites.
