Anthropic CCAR-F Exam Syllabus Topics:

Anthropic Claude Certified Architect - Foundations Sample Questions:

Question 1

Your update_user_profile tool accepts a user_id (required) and an optional fields_to_update object. In testing, Claude frequently omits user_id or passes incorrectly structured data. What is most critical for helping Claude understand what parameter values to provide?

A. Strict JSON Schema type constraints marking user_id as required and defining fields_to_update as an object type
B. Clear parameter descriptions explaining expected format, such as "user_id: UUID of the user to update (required)"
C. Detailed error responses explaining why invalid parameter values were rejected
D. Verbose parameter names encoding format hints, such as user_id_string_uuid_format

Question 2

You are building a structured data extraction system using Claude. The system extracts information from unstructured documents, validates the output using JavaScript Object Notation (JSON) schemas, and maintains high accuracy. It must handle edge cases gracefully and integrate with downstream systems.
Your extraction system implements automatic retries when validation fails. On each retry, the specific validation error is appended to the prompt. This retry-with-error-feedback approach resolves most failures within 2? attempts.
For which failure pattern would additional retries be LEAST effective?

A. The model extracts dates as ISO 8601 datetime strings ("2023-03-15T00:00:00Z") when the schema requires only the date portion (YYYY-MM-DD).
B. The model extracts keywords as a nested object organized by category when the schema requires a flat array of strings.
C. The model extracts citation counts as locale-formatted strings ("1,234") when the schema requires integers.
D. The model extracts "et al." for co-authors when the full list exists only in an external document not in the input.

Question 3

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

Question 4

Your control_device tool manages smart home devices through external APIs. When a device doesn't respond within the timeout period, the tool returns an error. Production logs show that the agent simply tells users "the device is not responding" without offering helpful next steps. Which error response structure would best enable the agent to provide useful follow-up?

A. Set is_error: false with an optimistic message indicating the command was dispatched successfully but device acknowledgment is still pending.
B. Set is_error: true with a brief "Device offline" message and provide a separate tool the agent can call to retrieve context-specific troubleshooting suggestions.
C. Set is_error: true with a structured technical error containing the device ID, timeout duration, and raw API response code for debugging purposes.
D. Set is_error: true with a message explaining the likely cause and suggesting troubleshooting steps the agent can offer the user.

Question 5

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. You need to design prompts that provide actionable feedback and minimize false positives.
Your pipeline includes a release-notes generation step that classifies and summarizes approximately 200 commits at the end of each weekly release cycle. Each commit is currently sent as a separate Messages API request using a Sonnet-tier Claude model. The release notes are not needed until the following morning, providing approximately 12 hours of acceptable latency.
Your team must reduce the per-token API cost while retaining the same model, prompts, and output quality.
Which approach satisfies all these constraints?

A. Replace the Sonnet-tier model with a Haiku-tier model to obtain a lower per-token price.
B. Submit the 200 requests through the Message Batches API with unique custom_id values and retrieve the results after the batch finishes.
C. Issue the 200 Messages API requests concurrently because parallel execution reduces the per- token price.
D. Concatenate all 200 commit messages into one Messages API request because reducing the number of requests always reduces token costs.
