Question 58
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 - You are implementing the agent loop for your support agent. After each Claude API call, you must decide whether to continue the loop (run requested tools and call Claude again) or stop (present the final answer to the customer). What determines this decision? What determines this decision?
- ACheck the `stop_reason` field in Claude’s response—continue if it is `tool_use` and stop if it is `end_turn`.
- BParse Claude’s text for phrases like “I’m done” or “Can I help with anything else?”—natural language signals indicate task completion.
- CSet a maximum iteration count (e.g., 10 calls) and stop when reached, regardless of whether Claude indicates more work is needed.
- DCheck whether the response contains assistant text content—if Claude generated explanatory text, the loop should terminate.
