CCAR-F Free Demo Questions (Part 2, Q41-Q80): 40 More Demo Questions for Preview

You should have preview CCAR-F free demo questions (Part 1, Q1-Q40) V8.02 before and verified that DumpsBase is the best partner during your Claude Certified Architect – Foundations (CCAR-F) exam preparation. Today, we will continue to share 40 more demo questions in Part 2, heloing you preview more about the full version:

1. During a tool execution step, your agent's lookup_customer tool fails to connect to the external database due to a timeout.

What is the architecturally correct way to handle this error and propagate it back to Claude?

Return a structured error response with isError: true, specify the error category (e.g., timeout), indicate if it is retryable, and provide context about what was attempted.

Silently return an empty JSON array [J so the agent can smoothly transition to trying an alternative lookup method.

Return a generic string like { "error" : " Operation failed" } to prevent leaking internal database infrastructure details to the LL

Throw a fatal system exception to immediately terminate the agentic loop and trigger a fallback to a human operator.

2. In a hub-and-spoke multi-agent architecture, what is the best practice for passing context from the coordinator agent down to a specialized subagent?

Share the entire coordinator conversation history to ensure the subagent has maximum context.

Pass only the explicit context, findings, and parameters specifically relevant to that subagent's assigned subtask.

Grant the subagent access to a shared global state object where the coordinator writes its findings.

Subagents automatically inherit the coordinator's full context window, so no explicit passing is needed.

3. When building an agent that queries a backend order system, the lookup_order tool returns a JSON object with 40+ fields, but the age only needs the order status, shipping date, and tracking number.

What context optimization technique should be applied?

Implement a PostToolUse hook to trim the verbose tool outputs, returning only the relevant fields to the agent's context.

Prompt the model to ignore the irrelevant fields after the full JSON object is appended to the conversation history.

Utilize the /compact command immediately after every tool call.

Use a PreToolUse hook to block the tool call entirely and escalate to a human.

4. A developer at builds an MCP server to standardize repetitive actions for the engineering team. They want to provide ready-to-use message sequences with specific formatting instructions that bypass the need for users to write them from scratch.

Which MCP component fulfills this requirement?

MCP Subagents

MCP Prompts

MCP Tools

MCP Resources

5. An agentic loop is the core execution pattern for Claude-based agents.

When building an agent, how should the loop reliably determine when to terminate and return a final response to the user?

Parse the assistant's natural language text output to check for keywords like 'task complete' or 'l am done'.

Set a hard maximum iteration cap of 10 loops to prevent infinite execution and terminate when reached.

Check the stop_reason field of the API response and exit the loop when it equals end_turn.

Monitor the token count of the conversation and stop when it approaches the context window limit.

6. An MCP server offers a templated resource to fetch specific documentation pages by ID.

What is the correct URI syntax pattern utilized by the MCP Python SDK to represent this parameterized resource?

Option A

Option B

Option C

Option D

7. What is the primary architectural difference between enforcing a business rule via a system prompt versus using an Agent SDK hook?

Prompts execute after the tool runs, while hooks execute before the prompt is processed.

Prompts are deterministic, while hooks rely on the model's probabilistic reasoning.

Hooks provide 100% reliable deterministic enforcement, whereas prompts are probabilistic and can occasionally be ignored by the LL

Prompts require an active MCP server connection, while hooks run strictly within the Claude desktop application.

8. When orchestrating an agentic workflow using the Claude Agent SDK, you must enforce a strict business rule: the agent is never allowed to issue refunds over $500.

What is the most robust and deterministic method to implement this constraint?

Add a capitalized warning in the system prompt: NEVER process a refund exceeding $500.

Implement a PostToolUse hook that intercepts the process_refund tool inputs, checks the amount, and programmatically blocks execution if it exceeds 500.

Configure the agent's tool_choice parameter to auto so it can decide when a refund is inappropriate.

Provide few-shot examples showing the agent refusing to process a $600 refund.

9. Using the FastMCP Python SDK, which decorators are used to expose capabilities to an MCP client? Choose 2 correct answers.

@mcp.tool

@mcp.agent

@mcp.action

@mcp.resource

10. When a subagent encounters a timeout while querying an external database, what is the best practice for propagating this failure back to the coordinator agent?

Return a generic 'search unavailable' string to avoid leaking infrastructure details to the LL

Catch the timeout and silently return an empty array [ ] marked as successful so the workflow continues smoothly.

Return structured error context including the failure type, the attempted query, and partial results so the coordinator can make an intelligent recovery decision.

Terminate the subagent process immediately and throw a fatal system exception to the top-level handler.

11. You are integrating Claude Code into a GitHub Actions CI/CD pipeline to automate pull request reviews.

Which flag combination must be used to ensure the process runs without hanging and produces machine-parseable output?

Option A

Option B

Option C

Option D

12. When planning complex multi-flle architectural changes, such as a monolith-to-microservices migration, why is it recommended to use plan mode rather than direct execution?

Plan mode automatically generates missing unit tests for legacy code before executing.

Plan mode utilizes the Message Batches API to reduce token costs by 50 percent.

Plan mode restricts Claude to using only read-only tools to explore the codebase, design a strategy, and get developer approval before making costly modifications.

Plan mode overrides the token limit context window by executing across multiple continuous sessions automatically.

13. When splitting a generic MCP tool (e.g., analyze_document) into purpose-specific tools, which of the following represent improved tool design practices? Choose 2 correct answers.

Renaming the tools to have completely identical descriptions to let the LLM randomly balance the load.

Creating specific tools with defined input/output contracts like and sununarize_content.

Eliminating functional overlap by ensuring descriptions differentiate each tool's exact purpose.

Combining all extraction and summarization functions into a single tool with 25 optional parameters.

14. While configuring prompt engineering standards for a production application, you must decide when to implement few-shot examples.

Which of the following scenarios represent the most effective use cases for few-shot prompting? Choose 2 correct answers.

Ambiguous classification tasks where the boundaries between categories are fuzzy or subjective.

Simple, well-defined data extraction tasks with clear objective criteria.

Tasks requiring standard output formats like valid JSON, where tool_use is already implemented.

Tasks requiring a custom, non-standard output format that Claude does not handle natively.

15. To maintain a clean and modular configuration, you want to split a monolithic CLAUDE.md file into distinct, topic-specific rule files.

How can you include these external rule files into your main project configuration?

Option A

Option B

Option C

Option D

16. To allow a coordinator agent to spawn specialized subagents in a multi-agent orchestration setup, which specific configuration must be applied to the coordinator?

Set the tool_choice parameter to auto for the coordinator agent.

The coordinator's allowedTools array must explicitly include the Task tool.

The subagent must be initialized with an inherit_context: true flag.

Configure a PreToolUse hook to automatically manage the spawning process.

17. According to best practices, which of the following scenarios should trigger a developer to use Plan Mode in Claude Code? Choose 2 correct answers.

When implementing multi-file architectural changes.

When adding a single console. log statement to a known file.

When evaluating multiple valid approaches for a new feature implementation.

When fixing a minor typo in project documentation.

18. Your CI pipeline must consume Claude's code review feedback programmatically to post inline comments on a GitHub pull request.

How should you enforce the exact structural shape of the output?

Use regex to parse the unstructured markdown text output returned by Claude.

Add - -output-format json and supply the required structure via the --json-schema CLI flag.

Inject a PostToolUse hook that formats the text output into a JSON object.

Provide at least 10 few-shot examples of valid JSON structures in the system prompt.

19. An architect is designing an MCP tool that occasionally fails due to downstream rate limits.

Which fields should be included in a well- designed structured error response to help the agent recover? Choose 2 correct answers.

isError: true

system_prompt_override

isRetryable: true

temperature _ adjustment

20. A development team wants to enforce TypeScript strict mode, specific ESLint rules, and API design standards for all developers working on a shared repository.

Where is the correct location to configure these team-wide standards in Claude Code?

In the user-level configuration file located at ~/.claude/CLAUD

md.

In the project-level configuration file located at .claude/CLAUD

md or the project root.

In a directory-level configuration file located at src/api/CLAUD

md.

In the claude/settings.json file under the team_standards array.

21. When the coordinator agent delegates a subtask to a specialized document analysis subagent, what is the best practice for passing context to ensure optimal performance?

Share the full coordinator conversation history with the subagent so it has the maximum possible context.

Pass ONLY the explicit context and findings relevant to that specific subagent's assigned task.

Grant the subagent access to the coordinator's scratchpad file using a Read tool.

Use the /compact command to summarize the coordinator's history before injecting it into the subagent's context.

22. While working in Claude Code, you press Shift + Tab to enter Plan Mode.

Which subagent is typically associated with isolating the verbose discovery phase to prevent context window exhaustion during planning?

The Review subagent

23. When building the raw tool-handling conversation loop with the API/SDK, Claude may return a ToollJse block.

To properly continue the multi-turn agentic loop, what are the requirements for formatting and returning the result of the executed function to Claude? Choose 2 correct answers.

The result must be appended to the messages array inside a user role message containing a tool_result block.

The tool result block must include a that matches the ID generated by Claude's initial tool request.

The result must be passed back inside an assistant role message with an is_error'. false flag.

The tool result must strictly be a serialized JSON object; raw text strings will automatically trigger a loop termination.

24. What is the only reliable and architecturally correct signal in the Claude API to determine whether an agentic loop should continue executing tools or terminate?

Parsing the assistant's natural language text output for completion keywords like 'task complete'.

Inspecting the stop_reason field of the response for tool_use versus end_turn.

Monitoring the total token count and exiting the loop when it reaches the context window limit.

Setting a hard maximum iteration cap of 5 loops to prevent infinite execution.

25. In Model Context Protocol architecture, what is the primary distinction between an MCP Tool and an MCP Resource?

Resources execute functions that perform backend mutations, whereas Tools expose data catalogs.

Resources expose static or templated data that clients can fetch to inject into prompts, whereas Tools are executable functions that perform actions.

Resources are hosted locally via stdio, whereas Tools are hosted remotely via HTT

Resources provide pre-built conversation templates, whereas Tools provide context history.

26. A customer support agent built with the Claude Agent SDK needs to correctly identify when to resolve a case autonomously versus when to trigger human escalation.

Which of the following represents an architectural anti-pattern for triggering escalation?

Escalating when the agent detects a policy gap not covered by its existing knowledge base.

Escalating immediately when the customer explicitly demands to speak to a human representative.

Escalating based on negative customer sentiment or self-reported low model confidence scores.

Escalating when a deterministic programmatic hook blocks a business operation that exceeds the agent's permission limits.

27. When using a hook to normalize heterogeneous data formats (e.g., standardizing different date formats returned by multiple external APIs) before the LLM processes them, which hook pattern is typically used?

A PreToolUse hook that modifies the user's prompt.

A PostToolUse hook that intercepts and transforms the tool results.

A Notification hook that alerts the user of data inconsistencies.

A SubagentStop hook that triggers re-evaluation.

28. An AI extraction system processes thousands of financial documents. The dashboard displays an impressive 96% overall aggregate accuracy. However, downstream teams complain about frequent errors.

What is the most likely oversight in the review and monitoring design?

The system is using prompt chaining instead of dynamic adaptive decomposition.

Aggregate accuracy metrics can mask severe per-document-type failures (e.g., invoices failing at 70% while receipts succeed at 99%).

The extraction is using JSON schema tool_use which guarantees semantic correctness but fails structural checks.

The system lacks a PostToolUse hook to block large financial transactions.

29. Using the @anthropic-ai/claude-agent-sdk, you want to programmatically narrow the set of tools available to a specific query loop to prevent the agent from making unintended modifications.

Which configuration is used to restrict tools in the SDK?

Pass the allowedTooIs: [ " Read, '" ' Glob"] array inside the options object of the query() function.

Inject a permissions: read-only tag into the top-level AgentDefinition.

Set tool choice: "none" to force the model to only use search tools.

Edit the. mcp. j son file to globally disable the write tools for the entire project.

30. When orchestrating complex workflows, you must decide between prompt chaining (fixed sequential pipelines) and dynamic adaptive decomposition.

In which scenario is dynamic adaptive decomposition the preferred architectural choice?

When conducting predictable, multi-aspect code reviews where the sequence of analysis is static.

When executing an open-ended investigation task where intermediate discoveries dictate the next required steps.

When applying deterministic compliance policies to financial transaction requests.

When extracting structured JSON data from standardized invoice templates.

31. You need Claude to output raw JSON directly to the user interface of your application, without any conversational preamble or markdown formatting.

Which prompt engineering technique achieves this?

Add "DO NOT USE MARKDOWN" to the end of the user prompt.

Combine Assistant Message Prefilling ```json with and use ```as a stop sequence.

Set max_tokens to exactly match the length of the JSON string.

Provide a 10-shot example list of raw JSON outputs.

32. When implementing an agentic loop using the Claude API, what is the only architecturally reliable signal to determine whether the loop should terminate or continue executing?

Parsing the assistant's natural language text output for completion keywords like 'task complete'.

Inspecting the stop_reason field of the API response for tool_use versus end_turn.

Implementing a hard maximum iteration cap of 5 loops to prevent infinite execution.

Monitoring the total token count and exiting when it reaches the context window limit.

33. You are managing context in a long-running Claude Code session that has accumulated a large amount of exploratory tool calls. You want to free up context space without completely losing the memory of what was previously worked on.

Which techniques are recommended? Choose 2 correct answers.

Use the /compact command to summarize conversation history and reclaim context space.

Use the /clear command to erase all history and rely on the model's pre-trained knowledge.

Save key findings to a scratchpad file and delegate verbose exploration to subagents.

Delete older messages from the conversation array manually to ensure hard truncation.

34. A engineer is creating a reusable custom Skill in. claude/skills/refactor/SKILL.md. The skill requires an isolated context window to avoid polluting the main session with exploration noise, and must be restricted to only reading files (no modifications).

Which frontmatter configurations are required? Choose 2 correct answers.

isolation: true

context: fork

allowed-tools: Read, Grep, Glob

permissions: read-only

35. When building a multi-agent research pipeline using the Claude Agent SDK, which of the following practices represent architectural anti- patterns that must be avoided? Choose 2 correct answers.

Silently returning empty result sets for failed API lookups instead of reporting access failures.

Using a flat architecture where all agents share a global state and full conversation history.

Emitting multiple Task tool calls in a single coordinator response to execute subagents in parallel.

Requiring subagents to output structured claim-source mappings to preserve attribution.

36. You are reviewing the escalation logs for a customer support agent. The agent currently escalates cases whenever it detects an angry customer tone, even for simple tasks like password resets.

What is the architectural flaw in this escalation design?

Sentiment does not equal task complexity; the agent should escalate based on objective criteria like policy gaps or explicit human requests, not emotion.

The agent should have processed a refund automatically to calm the customer down before escalating.

The sentiment threshold is set too low; it should only escalate if the customer uses specific profanity.

The agent lacks a PreToolUse hook to normalize the customer's text input before processing.

37. A engineering team wants to share formatting rules, testing guidelines, and preferred libraries across their entire repository.

Where is the correct location to configure these team-wide standards in Claude Code?

In the user-level configuration file located at ~/. claude/CLAUD

md.

In the project-level configuration file located at. claude/CLAUD

md or the project root.

In a directory-level configuration file located at tests/CLAlJD

md.

In the global .mcp.json file.

38. To prevent Claude from fabricating values when a requested field is absent from the source document, how should you engineer your JSON extraction schema?

Design the field with "type”: [" string, “null"] and mark it as optional/nullable.

Add a system prompt instruction to "never fabricate data".

Set the tool parameter tool_choice: " any".

Reduce the temperature to 0.0 to eliminate hallucinations.

39. You need to deterministically block any refund transaction that exceeds $500, escalating it to a human instead.

What is the architecturally correct method to enforce this critical business rule using the Agent SDK?

Add a strong, capitalized warning in the agent's system prompt forbidding refunds over $500.

Provide 5 negative few-shot examples showing the agent successfully refusing high-value refunds.

Implement a hook (e.g., PostToolUse or PreToolUse) to programmatically intercept and block the tool call execution.

Set the agent's tool_choice parameter to auto so it can assess the financial risk dynamically.

40. When integrating Claude Code into continuous integration and delivery pipelines, which of the following practices are highly recommended for reliability and automation? Choose 2 correct answers.

Executing Claude Code using the -p flag to ensure the process runs non-interactively.

Having the same session that generated the code perform the final review to ensure context consistency.

Isolating the code generator session from the code reviewer session to eliminate confirmation bias.

Using the Message Batches API to execute blocking pre-merge pull request checks to save costs.
