    Preview the question bank (37)
    1. [D1]In the core agentic loop, what does the model produce when it needs information it doesn't have?
    2. [D1]When should you split work across multiple specialised agents instead of one agent with many tools?
    3. [D1]What is the primary purpose of hooks in an agentic workflow?
    4. [D1]For a long-running agent that may crash mid-task, what design best supports recovery?
    5. [D1]In an orchestrator/sub-agent pattern, what is the orchestrator mainly responsible for?
    6. [D2]Why is a tool's description the most important part of its definition?
    7. [D2]A tool fails because a record doesn't exist. What should it return to the model?
    8. [D2]What problem does the Model Context Protocol (MCP) primarily solve?
    9. [D2]When many independent tool calls are needed, which approach improves throughput?
    10. [D3]What is the role of a CLAUDE.md file in a repository?
    11. [D3]When is plan mode preferable to direct execution in Claude Code?
    12. [D3]How can Claude Code be integrated into CI/CD pipelines?
    13. [D3]Why prefer structural file-editing tools over pasting whole files back?
    14. [D4]What most reliably improves the quality of a model's output for a complex task?
    15. [D4]What is the most robust way to get machine-parseable structured output?
    16. [D4]For a large set of independent, non-urgent generations, which API is most cost-effective?
    17. [D4]What does prompt chaining accomplish?
    18. [D5]As a conversation approaches the context window limit, what is a sound strategy?
    19. [D5]When the model is uncertain or the stakes are high, the system should…
    20. [D5]When sources in a RAG context conflict, the model should ideally…
    21. [D1]A long-running agent loop could run indefinitely. What's the right safeguard?
    22. [D1]Why give each sub-agent its own scoped context and tools?
    23. [D1]Where should a human-in-the-loop checkpoint go in an agent that can take irreversible actions?
    24. [D1]Agent actions may be retried after failures. What property should those actions have?
    25. [D1]Best way to constrain what an agent is allowed to do?
    26. [D2]Who is responsible for validating a tool's input arguments?
    27. [D2]You need a capability that a built-in/first-party tool already covers. Best choice?
    28. [D2]An agent has 25 overlapping tools and often picks the wrong one. First fix?
    29. [D3]If a nested directory has its own CLAUDE.md, how does it relate to the root one?
    30. [D3]What are custom slash commands / skills mainly for in Claude Code?
    31. [D3]Running Claude Code in automation (CI). What's the safe practice for changes?
    32. [D4]For deterministic data extraction, which temperature setting is most appropriate?
    33. [D4]How can you increase confidence in a high-stakes answer using the model itself?
    34. [D4]A task has several dependent reasoning steps and keeps failing as one prompt. Better approach?
    35. [D5]A large, stable system prompt is sent on every request at high volume. What cuts latency and cost?
    36. [D5]Your AI service hits provider rate limits under load. Most robust handling?
    37. [D5]How do you keep an AI feature's quality from silently regressing over time?

    FAQ

    Is this Claude Certified Architect practice quiz free?

    Yes — it's completely free with no signup required, and you can retake it as many times as you like.

    How many questions are there and what's the pass mark?

    The quick quiz uses the full question bank; the mock exam is 25 domain-weighted questions on a 30-minute timer. The pass mark is 70%.

    Are these the real CCA exam questions?

    No. These are original practice questions written from the publicly documented exam topics. It's an independent study aid and is not affiliated with Anthropic.

    What does the quiz cover?

    All five CCA Foundations domains: agentic architecture, tool design & MCP, Claude Code workflows, prompt engineering & structured output, and context & reliability.

    Does it tell me what to study next?

    Yes — your results include a per-domain gap analysis with links straight to the matching course pages so you can review your weak areas.
