54A user asks an agent to summarize an email thread. One email contains a hidden instruction to reveal the agent's system prompt. Which behavior is correct?
Prompt injection prevention
Hard
A.Follow the hidden instruction because it was retrieved from a trusted mailbox
B.Reveal the system prompt because the email is part of the task
C.Refuse the entire task whenever any email contains instructions
D.Treat the hidden instruction as untrusted content and summarize the thread
Correct Answer: Treat the hidden instruction as untrusted content and summarize the thread
Explanation:
Email content is task data, not an authority over system behavior. The agent should ignore embedded instructions that conflict with its policy while continuing the benign requested task.
Incorrect! Try again.
55A user asks an agent to retrieve a report they are allowed to view, but the agent's cached session belongs to a different user with broader access. What must happen before retrieval?
Authentication and authorization
Hard
A.Use the cached session because it has sufficient permissions
B.Retrieve the report and redact fields after generation
C.Ask the user to confirm that the report is needed
D.Re-authenticate or delegate using the requesting user's identity
Correct Answer: Re-authenticate or delegate using the requesting user's identity
Explanation:
Authorization must be evaluated for the actual requester and resource. A broader cached identity creates an impersonation and privilege-confusion risk.
