Question 134
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 - To "future-proof" the support agent, the team gave it 17 tools spanning refunds, shipping, account edits, analytics, and marketing email sends. Tool-selection accuracy dropped from 94% to 78% versus an earlier build that had 5 role-relevant tools. What is the most likely cause and fix?
- AThe system prompt is too short; list all 17 tools with detailed descriptions to restore accuracy.
- BToo many tools degrade selection reliability; scope the agent to only the tools its role needs plus a few utilities.
- CTool count is irrelevant; the regression must be a model-version change.
- DSwitch `tool_choice` from `"auto"` to `"any"` to force more decisive selection.
