Question 137
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: Developer Productivity Tools - You must migrate an internal logging library used across 52 files in an unfamiliar service. Several refactoring approaches look viable and you don't yet know all the call sites or their coupling. Which mode should you start in?
- ADirect execution: start editing files immediately and adjust as problems surface.
- BPlanning mode: explore with Read/Grep/Glob, map dependencies, and produce a plan for approval before changing anything.
- CDirect execution with one long up-front instruction covering all 52 files at once.
- DSkip planning and run a single batch refactor command across the repo.
