Microsoft GH-300 Practice Test 10
Question 90
An AI patch contains a missing authorization check, leaked test credentials, and claims that a failing suite is wrong. Which THREE actions are appropriate? (Select THREE.)
- Merge without review because a licensed Copilot tool was used.
- Disable all CI tests to prevent future false alarms.

- Add the missing authorization control and a negative regression test.
Explanation
Correct Answers

Question 91
A new developer sees no Copilot completions in VS Code despite being assigned a seat. What should be checked first?
- Consult the current IDE-specific Copilot feature matrix and extension release requirements.
- Confirm the GitHub account is signed in and the approved Copilot extension is enabled.
- Check language support, editor extension state, and per-language suggestion settings.
- Review the supported network allowlist and proxy or certificate settings with the administrator.
Explanation
Correct Answer
B:Authentication and extension availability are prerequisites to IDE suggestions.
Incorrect Answers
A:Surface and version support is not identical across all Copilot clients. authentication and extension availability are prerequisites to IDE suggestions.
C:Per-language and editor configuration can suppress inline completion despite an active seat. authentication and extension availability are prerequisites to IDE suggestions.

- Check language support, editor extension state, and per-language suggestion settings.
- Review the supported network allowlist and proxy or certificate settings with the administrator.
- Confirm the GitHub account is signed in and the approved Copilot extension is enabled.

D:Authentication and extension availability are prerequisites to IDE suggestions. What should be validated. Connectivity and TLS interception can prevent the IDE client from reaching the service.
Question 95
A developer with an organization-provided Copilot seat sees no suggestions and receives a permission error in VS Code. Which TWO checks most directly address access? (Select TWO.)
- Confirm the IDE is signed in to the GitHub account that holds the assigned seat.
- Disable certificate verification permanently to hide the permission message.
- Delete the application source files to refresh Copilot.
- Assume a seat makes every beta feature available in every IDE.
- Confirm the Copilot extension and organization feature policy permit the requested IDE capability.
Explanation
Correct Answers
A:Entitlement follows the effective authenticated identity.
E:Client installation and managed policies are prerequisites to suggestions.
Incorrect Answers
B:Removing TLS checks adds security risk and does not solve entitlement issues.
C:Removing code does not repair authentication or feature policy.
D:Client-version and organization limitations still apply.
Question 96
A developer has nearly finished writing a pure helper function and wants a few predictive lines without a conversation. Which interaction fits?
- Review and selectively accept or edit the inline suggestion as supported by the IDE.
- Use inline code suggestions at the cursor and inspect the proposed ghost text.
- Treat the suggestion as transient context-dependent assistance, not a saved repository change.
- Check whether an edit was actually applied, then inspect the working-tree diff.
Explanation
Correct Answer
B:Inline completion fits small local continuation based on editor context.
Incorrect Answers
A:Suggested text is optional and should be inspected before entering the codebase. Inline completion fits small local continuation based on editor context.
C:Ghost text does not become source until the developer accepts it. inline completion fits small local continuation based on editor context.
D:Conversational code blocks alone do not establish that source files were changed. Which interaction fits. Inline completion fits small local continuation based on editor context.
Question 97
A programmer needs to explain why an unfamiliar function returns the wrong value. Which Copilot surface is better suited?
- Ask Copilot Chat to explain the selected code and relevant dependencies.
- Use inline code suggestions at the cursor and inspect the proposed ghost text.
- Treat the suggestion as transient context-dependent assistance, not a saved repository change.
- Check whether an edit was actually applied, then inspect the working-tree diff.
Explanation
Correct Answer
A:A conversational request supports explanation and follow-up rather than only insertion.
