Question 45
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: Code Generation with Claude Code - You’re adding error-handling wrappers around external API calls across a 120-file codebase. The work has three phases: (1) discover all call sites and patterns, (2) collaboratively design the error-handling approach, and (3) implement wrappers consistently. In Phase 1, Claude generates large output listing hundreds of call sites with context, quickly filling the context window before discovery finishes. Which approach is most effective to complete the task while maintaining implementation consistency?
- AUse an Explore subagent for Phase 1 to isolate verbose discovery output and return a summary, then continue Phases 2–3 in the main conversation.
- BDo all phases in the main conversation, periodically using `/compact` to reduce context usage while moving through files.
- CSwitch to headless mode with `--continue`, passing explicit context summaries between batch calls to maintain continuity.
- DDefine the error-handling pattern in CLAUDE.md, then process files in batches across multiple sessions relying on the shared memory file for consistency.
