Question 110
A developer delegates a coding task to Copilot agent mode. A task description says only 'fix everything' across a large monorepo. Which response best addresses the stated risk or requirement?
- Use plan-oriented interaction before authorizing edits.
- Review the diff against compatibility requirements and revise before merging.
- Specify target behavior, relevant paths, and limits before delegation.
- Require explicit authorization and review before any high-impact command.
Explanation
Correct Answer
C:Ambiguous broad tasks invite excessive changes and unpredictable work.
Incorrect Answers
A:A reviewed plan can clarify the approach without immediately modifying code. This addresses a different situation: The developer wants an implementation design before any code is changed.
B:Autonomous execution does not remove the need for contract review. This addresses a different situation: The agent produces a patch but the new behavior breaks backward compatibility.
D:Tool access does not imply blanket authority to alter external systems. This addresses a different situation: The agent asks to run a command that modifies production infrastructure.
Question 111
A developer is installing GitHub Copilot CLI. The team has these independent requirements: (1) A Node-based workstation needs a cross-platform package installation route. (2) A first-time user has launched the CLI but cannot access Copilot features. Which TWO actions together satisfy all requirements? Choose TWO.
- Install the supported copilot-cli cask with Homebrew.
- Run the interactive sign-in flow and authenticate the GitHub account.
- Use the documented npm package @github/copilot with a supported Node version.
- Ask the organization administrator to check whether Copilot CLI is enabled.
- Follow the documented WinGet installation for GitHub.Copilot.
Explanation
Correct Answers
B:Authentication is required before a CLI session can use the account's entitlement.
C:The official CLI supports a cross-platform npm installation path.
Incorrect Answers
A:The documented CLI distribution includes a Homebrew cask. This addresses a different situation: A macOS engineer prefers Homebrew for terminal tooling.
D:Organization policy can disable a surface even when a user has a Copilot seat. This addresses a different situation: An enterprise user has a valid license but CLI access is blocked by policy.
E:Official installation options include a Windows package-manager route. This addresses a different situation: A Windows workstation uses a package manager rather than npm.

Question 115
A developer is installing GitHub Copilot CLI. An enterprise user has a valid license but CLI access is blocked by policy. What is the most defensible next step under responsible development practices?
- Run the interactive sign-in flow and authenticate the GitHub account.
- Follow the documented WinGet installation for GitHub.Copilot.
- Ask the organization administrator to check whether Copilot CLI is enabled.
- Install the supported copilot-cli cask with Homebrew.

Question 116
An engineer launches Copilot CLI in a repository. The first session asks whether the current project directory is trusted. Which action is the most appropriate response to this situation?
- Distinguish conversation suggestions from explicitly approved tool actions.
- Keep permissions read-oriented and reject unnecessary write actions.
- Limit the working scope and deny unrelated filesystem permissions.
- Inspect the repository and confirm trust only if its files are appropriate for AI access.
Explanation
Correct Answer
D:Trust decisions govern what local content the assistant may process.
Incorrect Answers
A:Starting a session alone does not authorize every proposed operation. This addresses a different situation: A developer believes starting an interactive Copilot CLI session automatically applies fixes.
B:Granting fewer capabilities reduces the chance of unintended changes. This addresses a different situation: The task needs only repository inspection, not file modification.
C:A narrow working set protects confidential or irrelevant material. This addresses a different situation: The agent repeatedly requests access to unrelated folders.
Question 117
An engineer launches Copilot CLI in a repository. The CLI proposes removing a large directory and requests permission. What should the developer do before accepting the proposed result?
- Limit the working scope and deny unrelated filesystem permissions.
- Distinguish conversation suggestions from explicitly approved tool actions.
- Inspect the repository and confirm trust only if its files are appropriate for AI access.
- Review the command's paths and implications before approving execution.
Explanation
Correct Answer
D:Commands can have destructive effects despite originating from an assistant.
Incorrect Answers
A:A narrow working set protects confidential or irrelevant material. This addresses a different situation: The agent repeatedly requests access to unrelated folders.
B:Starting a session alone does not authorize every proposed operation. This addresses a different situation: A developer believes starting an interactive Copilot CLI session automatically applies fixes.
