Question 80

A suggested production fix depends on an unknown runtime version, a disputed API limit, and an unverified race-condition diagnosis. Which THREE steps produce defensible evidence? (Select THREE.)

  1. Confirm the deployed runtime and installed dependency versions.
  2. Check the disputed API limit against current first-party documentation.
  3. Accept the response with the highest confidence score as verified.
  4. Reproduce concurrent execution and inspect timing and synchronization evidence.
  5. Assume the development machine exactly matches production.
  6. Remove synchronization checks to simplify the patch.

Explanation

Correct Answers

A:

Correct environmental facts determine which implementation behavior applies.

B:

Source verification resolves unsupported model claims about version-dependent limits.

D:

A suspected race requires observable shared-state behavior.

Incorrect Answers

C:

Confidence is not a runtime or protocol test.

E:

Environment parity must be demonstrated, not presumed.

F:

Eliminating guards can increase race-condition severity.

Question 81

An agent needs repository access to fix a serializer, but its tool scope includes production secrets. What is the safer setup?

  1. Grant only repository and test permissions needed for the serializer task.
  2. Validate publisher, checksum, necessity, and permitted execution before installing.
  3. Remove secret-bearing output and use masked diagnostic fields.
  4. Require protected-branch checks and the repository's approval conditions.

Explanation

Correct Answer

A:

Least-privilege tool access reduces risk from errors and injected instructions.

Incorrect Answers

B:

Agent suggestions are not a trusted software-supply-chain authorization. What is the safer setup. Least-privilege tool access reduces risk from errors and injected instructions.

C:

CI logs are durable artifacts that may be visible to broader audiences. least-privilege tool access reduces risk from errors and injected instructions.

D:

Automated authorship does not justify bypassing merge quality gates. least-privilege tool access reduces risk from errors and injected instructions.

Question 82

A developer gives a chat assistant an unrestricted cloud credential for convenience. What should be used instead?

  4. Validate publisher, checksum, necessity, and permitted execution before installing.

Explanation

Correct Answer

B:

Broad persistent secrets provide unnecessary access if exposed.

Question 84

A coding agent asks to install an unknown executable as a prerequisite. What should be verified?

  1. Require protected-branch checks and the repository's approval conditions.

  3. Validate publisher, checksum, necessity, and permitted execution before installing.
  4. Grant only repository and test permissions needed for the serializer task.

Explanation

Correct Answer

C:

Agent suggestions are not a trusted software-supply-chain authorization.

Incorrect Answers

A:

Automated authorship does not justify bypassing merge quality gates. What should be verified. Agent suggestions are not a trusted software-supply-chain authorization.

B:

Question 85

A generated script prints environment variables in CI logs. How should it be corrected?

  1. Validate publisher, checksum, necessity, and permitted execution before installing.
  2. Require protected-branch checks and the repository's approval conditions.
  3. Use scoped short-lived credentials or an approved delegated tool connection.
  4. Remove secret-bearing output and use masked diagnostic fields.

Explanation

Correct Answer

D:

CI logs are durable artifacts that may be visible to broader audiences.

Incorrect Answers

A:

Agent suggestions are not a trusted software-supply-chain authorization. cI logs are durable artifacts that may be visible to broader audiences.

B:

Automated authorship does not justify bypassing merge quality gates. How should it be corrected. CI logs are durable artifacts that may be visible to broader audiences.

C:

Broad persistent secrets provide unnecessary access if exposed. cI logs are durable artifacts that may be visible to broader audiences.

Question 86

A developer encounters a persistently wrong completion in a repository. What is a constructive response?

  1. Remove the data, assess exposure, and follow the incident process if published.
  2. Consult the authorized administrator rather than trying to bypass the managed setting.
  3. Fix the access check and add a negative regression test before reopening review.
  4. Reject the unsafe completion and provide feedback with reproducible context.

Explanation

Correct Answer

D:

Feedback is useful when grounded in the actual defect rather than blind acceptance.

Incorrect Answers

A:

A post-generation cleanup does not alone establish that data was never disclosed. Feedback is useful when grounded in the actual defect rather than blind acceptance.

B:

Organization policies represent deliberate governance boundaries. feedback is useful when grounded in the actual defect rather than blind acceptance.

C:

A corrected control should be proven against unauthorized callers. What is a constructive response. Feedback is useful when grounded in the actual defect rather than blind acceptance.
