Question 370
A customer-support assistant retrieves external FAQ pages, and one page embeds instructions telling the agent to export internal tickets. Which limitation must be considered before claiming the issue is fully resolved?
Explanation
Correct Answer
Prompt filters alone cannot replace tool-side least-privilege authorization. This caution prevents extrapolating beyond the specific evidence or product boundary. LLM inputs are untrusted data even when they appear in a retrieved document. The unresolved point should be tested using retrieved prompt traces, tool-call logs, data-access policy and adversarial evaluation rather than assuming a working interface proves full compliance or resilience.
Incorrect Answers
Prompt filtering eliminates all need for tool-side authorization enforcement. This limitation is framed as a blanket exception, but the case requires a different, narrower caution. The relevant boundary is that prompt filters alone cannot replace tool-side least-privilege authorization. LLM inputs are untrusted data even when they appear in a retrieved document. Inspect retrieved prompt traces, tool-call logs, data-access policy and adversarial evaluation.
Model Armor is a substitute for all authorization at the data API boundary. The proposed claim mistakes an incomplete signal or product feature for a universal guarantee. The relevant boundary is that prompt filters alone cannot replace tool-side least-privilege authorization. LLM inputs are untrusted data even when they appear in a retrieved document. Inspect retrieved prompt traces, tool-call logs, data-access policy and adversarial evaluation.
A safe-looking answer means no unauthorized tool was executed in the background. This claim exceeds the evidence and ignores an important risk or operational dependency. The relevant boundary is that prompt filters alone cannot replace tool-side least-privilege authorization. LLM inputs are untrusted data even when they appear in a retrieved document. Inspect retrieved prompt traces, tool-call logs, data-access policy and adversarial evaluation.
