Question 320
A developer asks Copilot to change code inside a monorepo. The prompt says to refactor all modules but only one API is affected. What is the most defensible next step under responsible development practices?
- Include the relevant tests as acceptance criteria.
- Limit work to the affected call graph and named files.
- State the supported runtime and package versions.
- Restrict new dependencies unless they are explicitly justified.
Explanation
Correct Answer
B:Narrow scope reduces collateral changes and review time.
Incorrect Answers
A:Existing tests often encode contracts not explicit in prose. This addresses a different situation: The task references a behavior defined in integration tests.
C:Compatibility is determined by the target environment, not general latest syntax. This addresses a different situation: The project requires Python 3.11 compatibility, but examples use newer syntax.
D:Constraints can prevent unapproved architectural changes. This addresses a different situation: The assistant adds an unnecessary dependency to solve a local problem.
Question 321
A team creates prompts for version-sensitive library upgrades. The assistant proposes syntax from an older framework major version. Which action is the most appropriate response to this situation?
- Request compatibility adapters, feature flags, and measurable rollback criteria.
- Include current and target library versions in the prompt.
- Verify options against installed types and reference documentation.
- Include the release-note contract change and required behavior.
Explanation
Correct Answer
B:Version-specific requirements steer suggestions toward supported APIs.
Incorrect Answers
A:Operational migration requirements belong in the prompt. This addresses a different situation: The developer wants a safe incremental rollout for an API rewrite.
C:A refined prompt cannot eliminate the need for factual checks. This addresses a different situation: The assistant still claims an undocumented option exists in the new version.
D:External version facts should guide code generation. This addresses a different situation: The proposed patch ignores a documented breaking response type.
Question 322
A team creates prompts for version-sensitive library upgrades. A migration answer omits deprecated functions that must be removed. What should the developer do before accepting the proposed result?
- Include current and target library versions in the prompt.
- Request compatibility adapters, feature flags, and measurable rollback criteria.
- Verify options against installed types and reference documentation.
- Ask for explicit deprecated-API inventory and replacements.
Explanation
Correct Answer
D:A useful migration plan identifies unsupported legacy usage.
Incorrect Answers
A:Version-specific requirements steer suggestions toward supported APIs. This addresses a different situation: The assistant proposes syntax from an older framework major version.
B:Operational migration requirements belong in the prompt. This addresses a different situation: The developer wants a safe incremental rollout for an API rewrite.
C:A refined prompt cannot eliminate the need for factual checks. This addresses a different situation: The assistant still claims an undocumented option exists in the new version.
Question 323
A team creates prompts for version-sensitive library upgrades. The proposed patch ignores a documented breaking response type. Which response best addresses the stated risk or requirement?
- Include the release-note contract change and required behavior.
- Ask for explicit deprecated-API inventory and replacements.
- Include current and target library versions in the prompt.
- Verify options against installed types and reference documentation.

Question 325
A team creates prompts for version-sensitive library upgrades. The assistant still claims an undocumented option exists in the new version. Which recommendation directly resolves this issue?
- Ask for explicit deprecated-API inventory and replacements.
- Request compatibility adapters, feature flags, and measurable rollback criteria.
- Include the release-note contract change and required behavior.
- Verify options against installed types and reference documentation.

Question 326
An engineer is iteratively improving a Copilot response. The team has these independent requirements: (1) The initial code works only for empty input. (2) The assistant repeatedly suggests a solution already rejected for security reasons. (3) A team has reached a working patch but no documented regression test. Which THREE actions together satisfy all requirements? Choose THREE.
- Restate the rejected approach and governing security constraint.
- Accept every subsequent patch because the latest response states that it is verified.
- Add the regression test and run the full relevant suite.
- Share actual observed failure output and request a correction.
- Ask to retain the fix while removing unnecessary new abstractions.
- Supply a failing nonempty case and request a minimal correction.
Explanation
Correct Answers
A:Explicit negative constraints help prevent repetition.
C:Iteration should finish with verified behavior, not merely plausible code.
F:Targeted feedback helps focus the next iteration.
Incorrect Answers
B:A model assertion is not observed proof that a repair worked. This addresses a different situation: A developer wants to skip all execution checks after a prompt revision.
D:Measured errors are stronger evidence than a generated claim. This addresses a different situation: A test fails after a revised patch even though the explanation says it should pass.
E:Iteration can refine complexity and scope. This addresses a different situation: The generated change fixes a bug but adds unrelated helper classes.
