Free CCAR-F Practice Questions

Test your knowledge with the following CCAR-F practice questions. Try to answer each question before checking the correct answer and explanation.

Question 1

You are integrating Claude Code into your Continuous Integration/Continuous Deployment (CI/CD) pipeline. The system runs automated code reviews, generates test cases, and provides feedback on pull requests.

The automated review consistently flags patterns your team uses intentionally, including force-unwrapping optionals in test files, large coordinator classes that follow your established architecture, and internally maintained modules marked as deprecated in the public SDK.

Which approach prevents the model from generating these findings in the first place by supplying the project’s conventions as persistent context during every review?

A. Document the team’s accepted patterns and intentional conventions in the project’s CLAUDE.md file so the model receives this context during every review.
B. Configure the review to analyze only the changed lines in the diff without the surrounding file context.
C. Build post-processing keyword filters that suppress findings before results reach developers.
D. Have developers add inline suppression comments at flagged lines and preprocess diffs to exclude them.

Answer: A

Explanation:
CLAUDE.md provides persistent project-level instructions that can document coding conventions, architecture rules, and accepted exceptions. This helps Claude evaluate the code using the team’s actual standards instead of filtering false positives only after they are generated.

Question 2

You are building a multi-agent research system using the Claude Agent SDK. A coordinator agent delegates to specialized subagents that search the web, analyze documents, synthesize findings, and generate reports.

The synthesis agent currently converts all outputs into bullet points, causing financial comparisons to lose tabular clarity and news summaries to lose their narrative flow.

What change would most improve briefing quality?

A. Standardize all subagent outputs as prose summaries with inline citations.
B. Add a format-conversion layer that transforms every subagent output into a common intermediate representation.
C. Update the synthesis agent to render each content type appropriately—for example, financial data as tables, news as prose, and patent areas as structured lists.
D. Standardize all subagent outputs as JSON containing claim, evidence, source, and confidence fields.

Answer: C

Explanation:
Different information types are best presented in different formats. Financial metrics benefit from tables, news is clearer in connected prose, and categorized technology findings are naturally suited to structured lists.

Question 3

You are building a structured data extraction system using Claude. The system must extract event details from calendar invitations and output JSON that strictly conforms to a schema.

What approach provides the most reliable schema compliance?

A. Pre-fill Claude’s response with an opening brace to force JSON output.
B. Add instructions such as “Output only valid JSON” and retry if parsing fails.
C. Define a tool with the target schema as input parameters and have Claude call it with the extracted data.
D. Include detailed JSON formatting instructions and parse Claude’s text response.

Answer: C

Explanation:
A schema-defined tool creates an explicit structured contract for the model’s output. This is more reliable than depending only on prompt instructions because the returned tool arguments must align with the declared schema.

Question 4

You have configured all four subagents to access the complete set of 18 tools. During testing, agents frequently call tools outside their specialization.

What is the primary cause of this poor tool-selection behavior?

A. The agents’ role descriptions in their system prompts conflict with having access to tools outside those roles.
B. The tool definitions consume too much context-window space.
C. The coordinator cannot track which capabilities each subagent has.
D. Choosing from 18 tools exceeds a fixed reliability threshold.

Answer: A

Explanation:
A specialized agent should receive tool access that matches its defined responsibility. Giving unrelated tools to every subagent creates a mismatch between role instructions and available capabilities, increasing the chance of inappropriate tool selection.

Question 5

After implementing strict schema definitions, JSON syntax errors are eliminated, but some extractions still contain empty arrays or null values for required information that is present in varied document formats.

What is the most effective way to address these failures?

A. Retry the same request whenever validation detects empty required fields.
B. Add few-shot examples showing how to extract the same information from documents with varied structures.
C. Build a regex-based post-processing layer to populate missing fields.
D. Modify the schema to make the fields optional.

Answer: B

Explanation:
Strict schemas solve structural compliance, but they do not teach the model how to recognize information that appears in different layouts. Diverse few-shot examples help Claude learn where and how to find the required content across varied document structures.

Question 6

You are using Claude Code to accelerate software development. You need to add a date validation check to one existing function in a single file.

What is the most appropriate approach?

A. Use direct execution to make the change.
B. Start with extended thinking mode.
C. Enter plan mode first to create a detailed implementation strategy.
D. Enter plan mode to analyze how the validation might affect the wider reservation flow.

Answer: A

Explanation:
The change is small, localized, and clearly defined, so direct execution is appropriate. Plan mode is more useful when the scope is uncertain, multiple files are involved, or the implementation requires broader architectural reasoning.

Question 7

A coordinator invokes a web-search subagent, waits for the response, and then invokes a document-analysis subagent. These two tasks are independent.

How should you modify the system to run these subagents concurrently?

A. Switch both subagents to a faster model tier.
B. Structure the coordinator to emit both Agent tool calls in a single response rather than across separate turns.
C. Add instructions asking the coordinator to run the tasks simultaneously.
D. Create separate coordinator-subagent pairs and aggregate their results later.

Answer: B

Explanation:
Independent subagent calls can run in parallel when the coordinator emits both tool calls in the same orchestration turn. This removes unnecessary serial waiting while preserving one coordinating agent for result aggregation.

Question 8

A financial API agent returns structured metrics, a news-monitoring agent returns prose summaries, and a patent-analysis agent returns structured technology lists. The synthesis agent currently converts everything into bullet points.

What change would most improve briefing quality?

A. Standardize all outputs as prose.
B. Standardize all outputs as JSON.
C. Render each content type appropriately, such as tables for financial data, prose for news, and structured lists for technology areas.
D. Convert every result into one common representation before synthesis.

Answer: C

Explanation:
The synthesis layer should preserve the semantic strengths of each content type. Uniform formatting can reduce clarity, while content-aware rendering improves readability and usefulness for the final audience.

Question 9

An engineer asks an agent to identify untested code paths in a legacy payment module spanning 45 files. After reading several files, the agent’s responses are becoming less accurate and it is losing track of earlier findings.

What’s the most effective approach to complete this investigation?

A. Spawn subagents to investigate specific questions while the main agent coordinates the findings.
B. Clear the context and selectively re-read the most important files.
C. Use Grep exclusively instead of reading full files.
D. Summarize all findings, clear context, and use the summary as the only reference.

Answer: A

Explanation:
Subagents allow separate investigation paths to run in isolated contexts while the main agent preserves the high-level understanding of the overall task. This is especially useful for large codebase exploration where extensive file reading can overwhelm the main context.

Question 10

A customer says:

“This is frustrating. I’ve explained my issue twice and nothing is being resolved. I want to talk to a real person NOW.”

The agent has not yet called any tools.

What should the agent do?

A. Explain what the agent can do and escalate only if the customer repeats the request.
B. Gather account context first, then escalate.
C. Immediately call escalate_to_human with the conversation history.
D. Ask one targeted question before escalating.

Answer: C

Explanation:
The customer has made an explicit request for human assistance. The agent should respect that request immediately rather than delaying the transfer with additional investigation, questions, or autonomous actions.
