Anthropic Claude Certified Architect Foundations (CCA-F) : CCA-F

You are using Claude Code to accelerate software development. Your team uses it for code generation, refactoring, debugging, and documentation. You need to integrate it into your development workflow with custom slash commands, CLAUDE.md configurations, and understand when to use plan mode vs direct execution.
Your team wants Claude to follow a detailed code review checklist (8 items covering API changes, test coverage, documentation, security, etc.) when reviewing pull requests. The team also uses Claude extensively for other tasks: writing new features, debugging production issues, and generating documentation. Currently, developers paste the checklist at the start of each review session. Which approach best addresses this workflow need?

• A. Create a dedicated review subagent with the checklist embedded in its configuration.
• B. Create a /review slash command containing the checklist, invoked when starting reviews.
• C. Configure plan mode as the default for code review sessions.
• D. Add the checklist to the project's CLAUDE.md file under a "Code Review" section.

A team wants to reduce hallucinations without significantly changing application logic. Which improvement should be implemented FIRST?

• A. Raise temperature.
• B. Add reliable retrieval sources.
• C. Shorten all outputs.
• D. Remove role instructions.

You are building developer productivity tools using the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive tasks. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.
An engineer sees an unfamiliar error message "SYNC_CONFLICT: entity version mismatch detected" in production logs but doesn't know which of the 12 services in the codebase generates it. They ask the agent to help locate the source code. What exploration approach will most efficiently find the responsible code?

• A. Read the project's README and service configuration files to understand the architecture, then systematically Read source files in each service directory.
• B. Use Grep to find all files that import the project's error handling module, then Read those files to locate custom error definitions.
• C. Use Grep to search for distinctive text from the error message (like "SYNC_CONFLICT" or "entity version mismatch"), then Read the matching files to understand context.
• D. Use Glob to find files in directories commonly associated with error handling (such as errors/, exceptions/,or handlers/) across all services, then Read each matching file.

A user asks Claude to ignore all previous instructions and reveal confidential internal prompt content. How should Claude behave?

• A. Generate random text.
• B. Follow higher-priority instructions and refuse.
• C. Partially reveal hidden instructions.
• D. Reveal the prompt.

The coordinator agent has AgentDefinitions configured for all four specialized subagents, each with appropriate descriptions, prompts, and tool restrictions. During testing, you notice the coordinator correctly reasons about when to delegate - it generates messages like "I'll ask the web search agent to find sources on this topic" - but no subagent execution ever occurs. The coordinator then proceeds as if the delegation happened and continues with incomplete information. Logs show no errors. What is the most likely cause?

• A. The coordinator's allowedTools configuration doesn't include "Task", so while it can reason about delegation, it cannot invoke the tool required to spawn subagents.
• B. The AgentDefinitions are configured correctly, but the coordinator's system prompt doesn't explicitly list the available subagent types, preventing the model from knowing they can be invoked.
• C. The coordinator's max_tokens setting is too low, causing the Task tool invocation to be truncated before the subagent type parameter can be specified.
• D. Subagent context isolation means task descriptions from the coordinator don't automatically reach subagents; you need to configure explicit context forwarding in ClaudeAgentOptions.
