Question 360

Copilot scaffolds a CRUD endpoint for a documented API, but the release requires both correct access control and conformant responses. Which TWO checks are required? (Select TWO.)

  1. Validate the endpoint's response schema and status codes through contract tests.
  2. Return HTTP 200 for every validation error.
  3. Accept all generated handlers without running tests.
  4. Log user passwords to simplify investigation.
  5. Verify per-record authorization and negative access cases.

Explanation

Correct Answers

A:

A compilable scaffold may still violate consumer expectations.

E:

Authentication alone cannot establish resource ownership permissions.

Incorrect Answers

B:

Blanket success codes hide failure semantics.

C:

A scaffold is unverified application logic.

D:

Credential logging creates avoidable security exposure.

Question 361

A legacy method has nested branching but all external behavior must remain unchanged. How can Copilot help?

  1. Restore bounded-memory processing for the specified input sizes.
  2. Search public call sites and preserve compatibility or plan a versioned breaking change.
  3. Suggest smaller functions and compare behavior with characterization tests.
  4. Inspect dependency direction and run module import and integration tests.

Explanation

Correct Answer

C:

Refactoring should improve structure without changing observable results.

Incorrect Answers

A:

A syntactically cleaner refactor can worsen resource use. refactoring should improve structure without changing observable results.

B:

Rename safety depends on consumers beyond one module. How can Copilot help. Refactoring should improve structure without changing observable results.

D:

Decomposition must respect the language's dependency graph. refactoring should improve structure without changing observable results.

Question 362

A developer asks Copilot to extract repeated error handling into a helper. What must be preserved?

Explanation

Correct Answer

C:

Deduplication can accidentally alter failure behavior.

Incorrect Answers

A:

Decomposition must respect the language's dependency graph. deduplication can accidentally alter failure behavior.

B:

Rename safety depends on consumers beyond one module. What must be preserved. Deduplication can accidentally alter failure behavior.

D:

Question 364

A code assistant proposes renaming a public library symbol. What check matters?

  1. Restore bounded-memory processing for the specified input sizes.
  2. Keep exception types, logging semantics, and call-site contracts intact.
  3. Search public call sites and preserve compatibility or plan a versioned breaking change.
  4. Suggest smaller functions and compare behavior with characterization tests.

Explanation

Correct Answer

C:

Rename safety depends on consumers beyond one module.

Question 365

A class extraction introduces circular module imports. What should the engineer validate?

  1. Inspect dependency direction and run module import and integration tests.
  2. Restore bounded-memory processing for the specified input sizes.
  3. Search public call sites and preserve compatibility or plan a versioned breaking change.
  4. Keep exception types, logging semantics, and call-site contracts intact.

Explanation

Correct Answer

A:

Decomposition must respect the language's dependency graph.

Question 366

A new service lacks API documentation but has code and tests. How can Copilot help?

  1. Replace them with placeholders and use approved credential setup instructions.
  2. Draft endpoint documentation from implementation and verify examples against tests.
  3. Draft changes from verified commits and remove unsupported claims before publishing.
  4. Generate a revised setup guide grounded in current manifests and run it in a clean environment.

Explanation

Correct Answer

B:

Code-derived docs still require developer fact checking.

Incorrect Answers

A:

Examples should never reveal reusable production secrets. Code-derived docs still require developer fact checking.

C:

Generated summaries can miss or misstate user-visible impacts. code-derived docs still require developer fact checking.

D:

Documentation correctness must be tested against real installation steps. How can Copilot help. Code-derived docs still require developer fact checking.

Question 367

A complex function has no explanatory comments. What prompt is useful?

  1. Draft endpoint documentation from implementation and verify examples against tests.
  2. Replace them with placeholders and use approved credential setup instructions.
  3. Ask Copilot to describe purpose, invariants, and nonobvious edge cases, then validate claims.
  4. Draft changes from verified commits and remove unsupported claims before publishing.

Explanation

Correct Answer

C:

Comments add value when they explain why rather than repeat syntax.
