  4. Reject fabricated evidence and report the actual test execution status.

Explanation

Correct Answer

A:

Generated prose cannot authoritatively determine legal or organizational obligations.

Incorrect Answers

B:

Incident attribution requires verifiable records, not confident wording. generated prose cannot authoritatively determine legal or organizational obligations.

Question 46

A new patch was generated by Copilot and passes compilation. What assurance is still required?

  1. Run behavior-focused tests and inspect security and error paths before merging.
  2. Compare workload query plans and write overhead under realistic data volumes.
  3. Inspect the destination, permissions, and intended effect before executing the command.
  4. Add boundary and adversarial cases tied to the changed validation rule.

Explanation

Correct Answer
