Question 59
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 - Production logs show the agent misinterprets outputs from your MCP tools: Unix timestamps from `get_customer`, ISO 8601 dates from `lookup_order`, and numeric status codes (1=pending, 2=shipped). Some tools are third-party MCP servers you cannot modify. Which approach to data format normalization is most maintainable? Which approach is most maintainable?
- AUse a PostToolUse hook to intercept tool outputs and apply formatting transformations before the agent processes them.
- BModify tools you control to return human-readable formats and create wrappers for third-party tools.
- CCreate a `normalize_data` tool that the agent calls after every data retrieval to transform values.
- DAdd detailed format documentation to the system prompt explaining each tool’s data conventions.
