Claude Code & Hierarchy — CCAR-F Practice Question
A representative Claude Certified Architect - Foundations (CCAR-F) exam question on Claude Code & Hierarchy. Work through it below, then read why each option is right or wrong.
Short answer
The correct answer is B. Keep universal rules at the repository level and place service-specific guidance near each service, avoiding duplication and conflicts.
Layered instructions mirror scope. Universal guidance remains visible while local files keep service context relevant and maintainable.
The Question
A monorepo has organization-wide security rules and service-specific test commands. How should Claude Code instructions be structured?
Why B is correct
Layered instructions mirror scope. Universal guidance remains visible while local files keep service context relevant and maintainable.
Why the other options are wrong
Option A does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (B) is the only one that fully meets every constraint stated in the question.
Option C does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (B) is the only one that fully meets every constraint stated in the question.
Option D does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (B) is the only one that fully meets every constraint stated in the question.
Key idea: Claude Code & Hierarchy
Layered instructions mirror scope. Universal guidance remains visible while local files keep service context relevant and maintainable. On the CCAR-F exam, questions in the "Claude Code Configuration and Workflows" domain test whether you can map a scenario's constraints to the right choice. Read the requirement carefully, eliminate options that violate any single constraint, and pick the one that satisfies all of them with the least operational overhead.
