Question 250

A suggestion matches public code and a reference is shown. What should the user do?

  1. Run normal developer validation and correct the code before review.
  2. Compare effective policy and display behavior before inferring model degradation.
  3. Review the match and its license or provenance before deciding to keep the suggestion.
  4. Do not treat the rejected text as a committed change or a verified test result.

Explanation

C:

The reference is review evidence, not automatic permission or a required rejection.

Question 255

After compaction, a critical acceptance criterion is missing from the chat. What should the user do?

  1. Filter tool output and summarize repeated failures with exact identifiers.
  2. Reintroduce the authoritative criterion from the project specification.
  3. Extract only the relevant error section and environment details.
  4. Consult each model's current supported context and feature limits.

Explanation

Correct Answer

B:

Summaries can omit details needed for later validation.

Question 256

An MCP search result contains a URL to an external private file. What should determine access?

  1. Verify the external system's resulting state before describing the operation as complete.
  2. Reject self-authorized escalation and ask the accountable owner for scoped access.
  3. Enforce data minimization and permissions separately on that custom tool.
  4. Use authorized connector permissions and verify the actual source before relying on it.

Explanation

Correct Answer

D:

A URL in tool text does not prove the model can open the underlying file.

Incorrect Answers

A:

Tool acknowledgments are not equivalent to confirmed provider-side effects. a URL in tool text does not prove the model can open the underlying file.

B:

Retrieved text cannot legitimately grant itself broader credentials. A URL in tool text does not prove the model can open the underlying file.

C:

Content exclusion on GitHub clients may not constrain third-party MCP processing. What should determine access. A URL in tool text does not prove the model can open the underlying file.

Question 257

A coding agent sends a repository excerpt to an approved external analysis tool. What must the owner evaluate?

  1. Verify the external system's resulting state before describing the operation as complete.
  2. Check the tool's data handling, scope, and organizational approval for that excerpt.
  3. Enforce data minimization and permissions separately on that custom tool.
  4. Use authorized connector permissions and verify the actual source before relying on it.

Explanation

Correct Answer

B:

External tools can introduce additional data processors beyond the model service.

Incorrect Answers

A:

Tool acknowledgments are not equivalent to confirmed provider-side effects. external tools can introduce additional data processors beyond the model service.

C:
