Question 180

During an enterprise Copilot rollout, the following condition is confirmed: A developer wants safe inspection without allowing code execution. Which action addresses the actual technical requirement?

  1. Use the reviewed diff and test evidence as source context
  2. Review, test, and commit the script through the standard CI workflow
  3. Restrict tools to read-only operations and request an analysis report
  4. Request appropriate Git permissions rather than bypassing controls

Explanation

Correct Answer

C:

The best response is "Restrict tools to read-only operations and request an analysis report". Tool-scoped access can support diagnosis without mutations. This directly addresses the condition: A developer wants safe inspection without allowing code execution.

Incorrect Answers

A:

The alternative "Use the reviewed diff and test evidence as source context" fits another situation: A developer asks an agent to produce a pull-request description. Accurate summaries must reflect real changes and verified tests. Here the condition is A developer wants safe inspection without allowing code execution; use "Restrict tools to read-only operations and request an analysis report" instead. Tool-scoped access can support diagnosis without mutations.

B:

The alternative "Review, test, and commit the script through the standard CI workflow" addresses A generated shell script needs to run repeatedly under CI. An interactive assistant's output requires a reproducible automation artifact. It does not resolve A developer wants safe inspection without allowing code execution; the correct choice is "Restrict tools to read-only operations and request an analysis report". Tool-scoped access can support diagnosis without mutations.

D:

"Request appropriate Git permissions rather than bypassing controls" targets A CLI agent cannot push a branch because the user has not approved write operations. Repository writes need distinct authorization from local analysis. That differs from A developer wants safe inspection without allowing code execution; the required decision here is "Restrict tools to read-only operations and request an analysis report". Tool-scoped access can support diagnosis without mutations.

Question 181

An engineering lead documents, the following condition is confirmed: A ticket requires updating an API contract and its three callers. Which approach is the most defensible?

  1. Ask it to execute the agreed tests under approved permissions
  2. Use agent mode with a defined test plan for coordinated edits
  3. Narrow the goal and constrain the permitted code areas
  4. Adjust instructions to update sources and run generation explicitly

Explanation

Correct Answer

B:

Select the action "Use agent mode with a defined test plan for coordinated edits". Agent mode can inspect and modify linked files across a task. It is the specific match for the scenario in which A ticket requires updating an API contract and its three callers.

Incorrect Answers

A:

For the different scenario An agent has edited the intended code but not run any relevant tests, "Ask it to execute the agreed tests under approved permissions" could be appropriate. Multi-step assistance still requires behavioral validation. The present requirement is A ticket requires updating an API contract and its three callers, which calls for "Use agent mode with a defined test plan for coordinated edits". Agent mode can inspect and modify linked files across a task.

C:

The action "Narrow the goal and constrain the permitted code areas" is useful when A task begins touching unrelated modules after a broad prompt. Autonomous selection of files must respect the requested scope. Under the stated condition A ticket requires updating an API contract and its three callers, instead choose "Use agent mode with a defined test plan for coordinated edits". Agent mode can inspect and modify linked files across a task.

D:

The alternative "Adjust instructions to update sources and run generation explicitly" fits another situation: An agent modifies generated artifacts that should be regenerated by the build. Hand-editing derived outputs can break reproducibility. Here the condition is A ticket requires updating an API contract and its three callers; use "Use agent mode with a defined test plan for coordinated edits" instead. Agent mode can inspect and modify linked files across a task.

Question 182

During an enterprise Copilot rollout, the following condition is confirmed: A developer wants to compare implementation approaches before edits. What should the team do first?

  1. Narrow the goal and constrain the permitted code areas
  2. Adjust instructions to update sources and run generation explicitly
  3. Use agent mode with a defined test plan for coordinated edits
  4. Use plan mode to produce a reviewable implementation proposal

Explanation

Correct Answer

D:

Given that A developer wants to compare implementation approaches before edits, choose "Use plan mode to produce a reviewable implementation proposal". Planning defers writes until architectural choices are considered. This targets the identified problem rather than a neighboring issue.

Incorrect Answers

A:

"Narrow the goal and constrain the permitted code areas" targets A task begins touching unrelated modules after a broad prompt. Autonomous selection of files must respect the requested scope.

Question 183

During a pull request review, the following condition is confirmed: An agent has edited the intended code but not run any relevant tests. Which recommendation correctly handles the situation?

  1. Adjust instructions to update sources and run generation explicitly
  2. Use agent mode with a defined test plan for coordinated edits
  3. Use plan mode to produce a reviewable implementation proposal

  1. Ask it to execute the agreed tests under approved permissions
  2. Narrow the goal and constrain the permitted code areas
  3. Use plan mode to produce a reviewable implementation proposal

Question 186

In a repository maintenance task, the following condition is confirmed: A large task has a separate documentation research component. What should the team do first?

  1. Supply a precise task description and required references
  2. Delegate research to a subagent and collect a bounded report
  3. Assign a read-only security-review specialist with limited tools
  4. Have the main agent reconcile the result against source-of-truth constraints

Explanation

Correct Answer

B:

Given that A large task has a separate documentation research component, choose "Delegate research to a subagent and collect a bounded report". Isolated subtask context avoids flooding the primary task. This targets the identified problem rather than a neighboring issue.

Incorrect Answers

A:

"Supply a precise task description and required references" targets A user expects a subagent to remember all parent-session state automatically. Context boundaries can omit implicit information from the parent. That differs from A large task has a separate documentation research component; the required decision here is "Delegate research to a subagent and collect a bounded report". Isolated subtask context avoids flooding the primary task.

C:

The alternative "Assign a read-only security-review specialist with limited tools" fits another situation: A security review should not modify source files. A subagent's capabilities can be constrained to its responsibility. Here the condition is A large task has a separate documentation research component; use "Delegate research to a subagent and collect a bounded report" instead. Isolated subtask context avoids flooding the primary task.

D:

The alternative "Have the main agent reconcile the result against source-of-truth constraints" addresses A subagent suggests a fix contradicting the main application's requirements. Delegated results are recommendations, not automatic authority. It does not resolve A large task has a separate documentation research component; the correct choice is "Delegate research to a subagent and collect a bounded report". Isolated subtask context avoids flooding the primary task.

Question 187

While onboarding an engineering team, the following condition is confirmed: A security review should not modify source files. Which recommendation correctly handles the situation?

  1. Delegate research to a subagent and collect a bounded report
  2. Assign a read-only security-review specialist with limited tools
  3. Delegate distinct self-contained tasks rather than sharing an unbounded thread
  4. Supply a precise task description and required references

Explanation

Correct Answer

B:

The choice "Assign a read-only security-review specialist with limited tools" matches the requirement: A security review should not modify source files. A subagent's capabilities can be constrained to its responsibility. This is the best-supported approach under the stated constraint.

C:

The alternative "Delegate distinct self-contained tasks rather than sharing an unbounded thread" addresses A maintainer wants two unrelated investigations run independently. Separate context reduces cross-contamination of assumptions. It does not resolve A security review should not modify source files; the correct choice is "Assign a read-only security-review specialist with limited tools". A subagent's capabilities can be constrained to its responsibility.
