CCDV-F sample questions

2 questions from the CCDV-F practice set, with the answer and explanation.

  1. Question 1
    An application receives a Claude response whose stop_reason is tool_use. What should the code do next?
    • A.
      Execute the requested tool, append its result to the conversation as a tool result block, and send the updated messages back to Claude
    • B.
      Treat the response as final and display its text to the user, since every reply from the API is a complete answer by design
    • C.
      Discard the response and retry the same request with a higher max_tokens value so that the tool call fits in the reply
    • D.
      Store the stop_reason in a log and end the session, because a tool_use value means the API has closed the conversation
    Show answer

    Correct answer:

    • A.
      Execute the requested tool, append its result to the conversation as a tool result block, and send the updated messages back to Claude

    Explanation

    A tool_use stop_reason means Claude is waiting for the application to run a tool, so the code must execute it and return the result as a tool result block. Showing the text as final or ending the session stops the loop too early. Raising max_tokens does not respond to a requested tool call.
  2. Question 2
    Opus is the most capable Claude tier and is generally the best fit for complex reasoning, while Haiku is the fastest and lowest-cost tier.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • A.
      True

    Explanation

    The Claude tiers trade capability against speed and cost, with Opus at the capable end and Haiku at the fast, economical end. Choosing a tier means weighing quality, latency, and cost for the task. The statement is true.
