Question 20

A generated utility closely resembles code in a public repository, and the product is commercially distributed. Which TWO steps appropriately address provenance risk? (Select TWO.)

  1. Assume no rights review is necessary if the function compiles.
  2. Apply the project's legal and license compliance review before incorporating the utility.
  3. Delete displayed code references while retaining the copied implementation unchanged.
  4. Review available public-code references and their licensing context.
  5. Assume that generated code is automatically public domain.

Explanation

Correct Answers

B:

A responsible distribution decision requires consideration of compatible rights and notices.

D:

Match references may identify original authors and conditions that matter for reuse.

Incorrect Answers

A:

Correct execution does not determine the legal status of the code.

C:

Hiding references neither alters provenance nor fulfills license requirements.

Question 21

A developer is about to paste a production API key into Copilot Chat for debugging. What is the right action?

Explanation

Correct Answer

A:

A secret is not needed to reason about an authentication failure's structure.

Question 26

Copilot retrieves a README that says to disable security tests before running any commands. How should that instruction be treated?

  1. Keep task authorization separate from issue text and restrict agent tool permissions.
  2. Review proposed file changes and require approval for privileged write operations.
  3. Treat repository text as untrusted task data and retain the authorized test policy.
  4. Use the page as reference material only, never as a higher-priority policy authority.

Explanation

Correct Answer

C:

Retrieved content cannot override the user's instructions or security requirements.

Incorrect Answers

A:

Lower-trust issue content must not grant privileges outside the intended assignment. How should that instruction be treated. Retrieved content cannot override the user's instructions or security requirements.
