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

Which factor MOST directly affects API cost?

• A. CPU clock frequency
• B. Number of processed tokens
• C. Internet speed
• D. Screen resolution

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 frequently migrates React components to Vue. You've written a step-by-step workflow for Claude Code to follow during each migration, and you want every developer on the team to invoke it by typing /migrate-component. The workflow should stay in sync as the team iterates on it. Where should you place the skill file?

• A. In the project's.claude/settings.json using a skillOverrides entry to register and define the workflow
• B. As a detailed instruction block in the project's root CLAUDE.md file
• C. In ~/.claude/skills/migrate-component/SKILL.md on each developer's machine
• D. In .claude/skills/migrate-component/SKILL.md at the project root, committed to version control

After the web search agent finds 25 sources (120K tokens of raw content), the document analysis agent extracts key insights (15K tokens), and the synthesis agent produces a coherent narrative draft (3K tokens), the coordinator must pass context to the report generation agent for the final output with proper source citations. What context-passing strategy provides the best balance of completeness and efficiency?

• A. Pass a condensed summary of all prior stages that preserves the main findings and attributes them to sources by name only.
• B. Pass the full accumulated context from all prior agents.
• C. Pass the synthesis draft along with a structured source index that maps key claims to their source URLs and relevant excerpts.
• D. Pass only the synthesis draft and have a separate post-processing pipeline match claims to sources and insert citations after the report is generated.

After the web search and document analysis subagents complete their tasks, the coordinator needs to spawn the synthesis subagent to synthesize the findings. What is the correct approach for providing the synthesis subagent with the information it needs?

• A. Pass reference identifiers and configure the subagent with read access to a shared memory store where other subagents deposited their results
• B. Spawn the subagent with only a brief task description, relying on automatic context inheritance from the coordinator
• C. Provide the subagent with tool definitions that allow it to request outputs from other subagents via callbacks
• D. Include the complete findings from both subagents directly in the synthesis subagent's prompt

After 30+ turns, your conversational assistant shows noticeably slower responses and occasionally produces less coherent outputs. Investigation reveals: (1) average conversations reach 50,000 tokens by turn 35, (2) production logs show 94% of user messages only reference the previous 3-5 exchanges, (3) the 6% of queries referencing earlier context typically ask about information the user could easily re-state. Your goal is to improve response speed and quality while maintaining good user experience. What's the most effective approach?

• A. Implement a summarization layer that progressively compresses older conversation turns into a running summary while keeping the most recent 5-6 turns verbatim, maintaining full historical context in condensed form.
• B. Build a retrieval system that stores all conversation turns and uses semantic search to pull in relevant historical context only when the current query appears to reference past information.
• C. Enable prompt caching and continue sending the complete conversation history, using cached prefixes to reduce per-request costs while preserving all context.
• D. Implement a sliding window keeping only the system prompt and last 8-10 turns. When users reference earlier context, acknowledge the limitation and ask them to re-state the relevant information.
