Question 127
CCA-F is a newly released exam. These practice questions reflect our best current understanding — the exact wording and question formats may change in the live exam until the certification matures. Use them to learn the concepts, not to memorize.
Scenario: Customer Support Agent - The `lookup_order` MCP tool fails because the orders backend timed out. It returns `{"isError": true, "content": "Operation failed"}`. The agent cannot tell whether to retry, change the query, or escalate, and ends up looping on the same call. What should the error response include?
- AJust a longer human-readable sentence describing what went wrong.
- BNothing extra; the agent should automatically retry every `isError` response.
- CStructured metadata: `errorCategory` (e.g., transient), `isRetryable`, a clear message, the attempted query, and any partial results.
- DAn empty success payload so the workflow keeps moving.
