Exam CCA-F Topic 1 Question 97 Discussion

Actual exam question for Anthropic's CCA-F exam
Question #: 97
Topic #: 1
An MCP tool configured for a quicktechie.com application fails to connect to its backend database due to a timeout. Why is it considered a critical anti-pattern to silently return an empty JSON array [] for this failure?

Suggested Answer: B Vote an answer

Distinguishing between an access failure (could not connect/check) and a valid empty result (checked successfully but found no data) is critical. Silently returning an empty array for a timeout misleads the agent into concluding the data does not exist, rather than knowing it needs to retry or escalate the access issue.
