And today is the first part, containing 40 demo questions.

1. Your project has React components, API handlers, and database models. Test files are spread throughout the codebase next to the code they test.

How can you ensure Claude automatically applies the correct testing conventions when generating code?

Consolidate all conventions in the root CLAUD

md file and rely on Claude to infer the correct section.

Create rule files in. claude/rules/with YAML frontmatter specifying glob patterns like **/*. test.tsx.

Create an MCP server that injects testing rules into the prompt manually.

Place a separate CLAUD

md file in each subdirectory containing test-specific conventions.

2. To optimize a CI/CD pipeline, your manager wants to use the Message Batches API to reduce costs by 50%. The pipeline includes a real-time, blocking pre-merge code review, and a separate nightly technical debt audit.

How should you apply the Batch API?

Use the Batch API for both workflows to maximize cost savings, utilizing status polling for the pre-merge check.

Use synchronous API calls for both workflows, as the Batch API does not support structured JSON schema outputs.

Use the Batch API strictly for the nightly technical debt audit, and retain synchronous real-time calls for the blocking pre-merge review.

Switch both to the Batch API, but implement a timeout fallback that switches to synchronous calls if the batch exceeds 5 minutes.

3. Your application has test files spread throughout the codebase next to the components they test. You want Claude to automatically apply specific testing conventions whenever it generates or edits a test file.

Which configuration method is most maintainable and deterministic?

Consolidate all testing conventions in the root CLAUD

md and rely on Claude's inference to apply them.

Create a rule file in. claude/rules/testing.md With YAML frontmatter specifying paths: [. test. tsx"].

Place a separate CLAUD

md file in every subdirectory that contains test files.

Define an MCP server resource to fetch testing standards dynamically.

4. Your automated extraction pipeline displays an impressive 96% aggregate accuracy on the dashboard. However, downstream teams complain about frequent errors when processing complex financial contracts.

What monitoring methodology resolves this visibility gap?

Tracking accuracy per document type and field (stratified metrics) instead of relying solely on aggregate metrics.

Increasing the overall sampling size randomly to capture a broader dataset.

Switching entirely to the Message Batches API to ensure complete asynchronous processing.

Utilizing fork_session to isolate contract documents into separate evaluation workflows.

5. When implementing multi-pass review architectures for automated CI/CD pipelines, why is configuring the exact same Claude SDK session to review its newly generated code considered a major anti-pattern?

It causes the token limit of the context window to exceed its maximum capacity.

The Message Batches API does not support synchronous self-review workflows.

Tools invoked in the first pass are permanently locked and cannot be reused in the second pass.

The reviewer retains the reasoning context from the generation phase, creating confirmation bias and reducing the likelihood of catching subtle flaws.

6. Which of the following statements represent correct principles of multi-agent orchestration design? Choose 2 correct answers.

Parallel execution of subagents is achieved by emitting multiple Task tool calls in a single coordinator response.

A flat architecture where all agents share a global state is generally preferred over a hub-and-spoke architecture.

The coordinator should route all inter-subagent communication to maintain observability and consistent error handling.

Subagents should automatically inherit the coordinator's memory across invocations to save token costs.

7. A application features a tool designed to fetch a user's profile. During execution, the tool fails to connect to the database due to a timeout.

Why is silently returning an empty array [ ] in this scenario considered a catastrophic anti-pattern?

It prevents the use of few-shot prompting in the next iteration.

It causes the agent to misinterpret an access failure (could not check) as a valid empty result, wrongly concluding the user does not exist.

It forces the model to ignore all subsequent tool calls in the session.

It causes the Claude API to throw a 400 Bad Request error due to missing required schema fields.

8. You are implementing a validation-retry loop for a structured data extraction prompt. The extraction fails a business logic validation (e.g., line items do not sum to the total).

Which techniques represent best practices for the follow-up retry prompt? Choose 2 correct answers.

Return a generic error message like There were errors in your extraction. Please try again.

Append specific validation errors, detailing which field failed and the nature of the discrepancy.

Include the original document and the failed extraction in the retry prompt to guide self-correction.

Increase the model temperature to 1.0 so it thinks of a different answer.

9. You are designing a prompt to extract structured data from unstructured documents. You decide to use tool_use with a strict JSON schem a.

What specific guarantee does this approach provide?

It guarantees both structural compliance and the semantic correctness of the extracted data.

It eliminates JSON syntax errors and guarantees structural compliance, but does not prevent semantic errors.

It guarantees the model will not hallucinate missing information.

It eliminates the need for validation-retry loops.

10. When implementing a multi-agent research system for a enterprise application, a coordinator agent must delegate a market analysis task to a specialized subagent.

What is the correct approach for passing context to this subagent?

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

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

Pass only the specific, explicit context relevant to the subagent's assigned subtask in the prompt.

Use the /compact command to summarize the coordinator history before passing it to the subagent.

11. A subagent attempts to query an external database but encounters a timeout.

How should this error be propagated back to the coordinator agent?

The subagent should silently return an empty JSON array to allow the workflow to proceed smoothly.

Return a generic 'Operation failed' string to prevent leaking infrastructure details.

Return structured error context, including the failure type (access failure), what was attempted, and partial results.

Throw a fatal exception to immediately terminate the entire research workflow.

12. When configuring Claude Code for a new project, you want to establish team-wide TypeScript strict mode conventions, while keeping your personal Vim keybindings private.

What is the correct architectural approach?

Option A

Option B

Option C

Option D

13. To integrate an MCP server providing database tools for a team, you must configure it so that all developers share the integration but do not leak secrets into version control.

What is the correct configuration approach?

Configure the server in the user-scoped ~/. claude. json file to keep credentials local.

Configure the server in the project-scoped .mcp. j son file using environment variable expansion like ${DB_TOKEN}.

Hardcode an encrypted API token directly in the .mcp.json file.

Store the credentials in an ignored secrets. json file referenced by CLAUD

md.

14. How can a coordinator agent effectively execute multiple subagents in parallel to speed up a complex research task?

By emitting multiple Task tool calls within a single response turn.

By invoking the parallel_execute method provided natively in the Agent SD

By using the fork_session command for each subagent sequentially.

By setting the concurrency frontmatter field to a value greater than 1.

15. When utilizing Claude Code's built-in tools for codebase exploration and modification, which of the following usages represent correct tool selections? Choose 2 correct answers.

Using Grep to search for all occurrences of a deprecated function name across the src/directory.

Using Glob to find all file paths that end in .test.tsx within the project.

Using Write to fix a minor typo in an existing, heavily documented configuration file.

Using Bash to execute find. "-name * .ts" to locate all TypeScript files.

16. A developer needs to migrate a monolithic application into microservices, requiring changes across 45+ files, updates to module dependencies, and new architectural boundaries.

Which execution approach in Claude Code is recommended for this task?

Use Direct Execution to incrementally modify files one by one until the migration is complete.

Use the /compact command heavily to fit all 45 files into the context window for a single-pass Direct Execution.

Use Plan mode to explore the codebase, map dependencies, and design an implementation strategy before committing to file modifications.

Write a static Prompt Chain that forces the agent to read, refactor, and save each file sequentially.

17. During a multi-agent synthesis phase, the coordinator receives conflicting financial statistics from a web search subagent and a document analysis subagent.

What is the required architectural pattern for handling this conflict?

Arbitrarily select the value from the document subagent, as internal documents are generally more reliable.

Average the two conflicting values together to provide a balanced estimate.

Maintain structured claim-source mappings to preserve information provenance (source, confidence, timestamp) allowing for an informed resolution.

Discard both values and prompt the user to manually input the correct statistic.

18. Where should a development team configure a shared Jira MCP server to ensure credentials are NOT leaked in version control?

In the user-level 4. claude. json file, requiring each team member to manually script the configuration.

In the project-level .mcp.json file, using environment variable expansion syntax like

Inside a dedicated secrets. json file that is committed to the repository.

As inline comments within the CLAUD

md file.

19. When configuring a project-level Jira Model Context Protocol (MCP) server for a development team, what is the required method for securely managing authentication credentials?

Hardcode the API tokens directly in the .mcp.json file to ensure all team members can access the integration.

Configure the server in the user-scoped ~/. claude. json file so credentials remain local to each developer.

Define the server in the project-scoped .mcp.json file using environment variable expansion like ${JIRA_TOKEN}.

Store the credentials in an encrypted secrets .json file referenced by the CLAUD

md configuration.

20. You need to create a reusable behavior for complex refactoring.

To prevent the exploration noise from polluting the main session's context window, which configuration should you use in your SKILL. md?

Set context: fork in the YAML frontmatter.

Set isolation: true in the YAML frontmatter.

Add the /compact command at the end of the skill's instructions.

Use a standard custom command in. claude/commands/instead of a skill.

Silently average the conflicting numerical values to provide a balanced estimate.

Require subagents to output structured claim-source mappings.

Preserve information provenance including the source, confidence level, and timestamp.

Arbitrarily select the value from the most recently updated database to resolve the conflict.

22. You are assigned to restructure a monolithic application into microservices, requiring architectural decisions and changes across 45+ files.

Which execution approach in Claude Code is recommended?

Start with direct execution and make changes incrementally, letting the implementation reveal the natural boundaries.

Use direct execution with a massive upfront prompt detailing how every service should be structured.

Enter plan mode to explore the codebase and design an implementation strategy before executing changes.

Write a static Prompt Chain that forces the agent to read and refactor each file sequentially.

23. A developer asks the agent to 'read the project configuration file to determine the database connection string'.

Which built-in tool represents the correct architectural choice for this task?

"database", "config. j son

Bash("cat config. j son")

Grep( Glob ( " config. j son ")

Read (" config. j son

24. A properly structured SKILL.md file relies on YAML frontmatter metadata to inform Claude of its capabilities.

Which of the following are REQUIRED fields in the skill frontmatter? Choose 2 correct answers.

name

description

allowed-tools

model

25. When designing a multi-agent research system for a enterprise application, which architectural pattern is recommended to manage parallel research tasks effectively?

A flat architecture where all agents share a global state and full conversation history to maximize context visibility.

A hub-and-spoke architecture where a central coordinator delegates tasks to specialized subagents with isolated contexts.

A sequential pipeline architecture where each agent passes its entire context and output directly to the next agent in the chain.

A monolithic architecture utilizing a single agent loaded with all available research and synthesis tools.

26. You are designing an MCP tool to look up customer orders.

Which approach to tool descriptions is recommended to ensure reliable tool selection by Claude?

Keep the description under 10 words to save context window tokens.

Include the input format, example queries, edge cases, and boundaries explaining when to use it versus similar tools.

Use the description solely to list the required JSON properties.

Leave the description blank and rely on Claude's semantic understanding of the tool's name.

27. A pull request modifies 14 files across a stock tracking module. When analyzing all files in a single pass, Claude provides superficial comments, misses obvious bugs, and produces contradictory feedback.

How should you redesign the multi-pass review architecture to resolve this?

Switch to a higher-tier model with a larger context window so all 14 files receive adequate attention in one pass.

Require developers to manually split large PRs into smaller submissions of 3-4 files before triggering the automated review.

Run three independent single-pass reviews on the full PR and only flag issues that achieve consensus across at least two runs.

Split the review into focused passes: analyze each file individually for local issues, followed by a separate integration-focused pass for cross-file data flow.

28. A developer is designing a hub-and-spoke multi-agent system.

How should context be passed from the coordinator down to a newly spawned subagent?

The subagent automatically inherits the coordinator's full conversation history by default.

Provide the coordinator's complete context window inside the Task tool prompt for maximum context visibility.

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

Write all context to a shared scratchpad file that all agents read globally before executing their turns.

29. The configuration hierarchy in Claude Code resolves settings from multiple levels.

Which of the following are valid configuration layers where CLAUDE.md files can be placed? Choose 2 correct answers.

User-level (e.g., 4. claude/CLAUD

md) for personal preferences.

Global system-level (e.g., /etc/c1aude/CLAl_JD

md) for machine-wide mandates.

Directory-level (e.g., src/api/CLAUD

md) for module-scoped conventions.

Cloud-level (e.g., s3 : //config/CLAUD

md) for distributed synchronization.

30. An automated pipeline is using a PreToolUse hook to block unauthorized file reads by evaluating the requested file path.

How does the hook command properly communicate to Claude *why* the action was blocked so the agent can adjust its behavior?

By returning an exit code of 2 and writing the explanation to standard error, which is fed back to Claude as feedback.

By silently terminating the session and initiating a new one with an updated system prompt.

By overriding the context window entirely with a generic access denied template.

By returning an empty JSON array [] on standard output.

31. Claude Code provides several built-in tools for codebase exploration and modification.

If an agent needs to fix a bug on line 42 of an existing, lengthy TypeScript file, which tool should be utilized to ensure unchanged content is safely preserved?

Write, passing the updated content block to rewrite the target file.

Bash, using standard Unix utilities like sed to replace the line.

Edit, providing the old text block and the new text block for targeted replacement.

Glob, searching for the specific line and replacing it via regex.

32. When designing an autonomous customer support agent, you must explicitly program the conditions under which it stops attempting to solve the problem and escalates to a human.

Which of the following are valid, objective escalation triggers? Choose 2 correct answers.

The agent detects a policy gap where no existing rule covers the customer's specific situation.

The agent assesses its own confidence level to be below 0.6 out of 1.0.

The customer explicitly demands to speak with a human representative.

The customer expresses high frustration and uses negative sentiment words.

33. When implementing a hub-and-spoke multi-agent architecture using the Claude Agent SDK, which of the following statements about subagent spawning and execution are correct? Choose 2 correct answers.

The coordinator agent must have Task included in its allowed Tools configuration to spawn subagents.

Subagents automatically inherit the full conversation history of the coordinator agent by default.

A single coordinator response cannot emit multiple Task tool calls; subagents must be spawned sequentially across separate turns.

Parallel execution is achieved when the coordinator agent emits multiple Task tool calls in a single response.

34. Which of the following tasks is the MOST appropriate use case for Direct Execution rather than Plan Mode?

Changing the state management library from Redux to Zu stand across a large React application.

Designing an implementation approach for a new API integration with unknown dependencies.

Fixing a specific bug with a clear stack trace in a single TypeScript file.

Restructuring the database schema and updating all corresponding repository models.

35. What is the primary difference in tool usage between Plan Mode and Direct Execution in Claude Code?

Plan Mode uses Write and Edit heavily to scaffold boilerplate code.

Plan Mode restricts Claude to using only read-only tools to analyze the codebase before executing.

Plan Mode completely disables all tool usage until the user explicitly permits it.

Plan Mode automatically switches to a higher-tier model with larger tool capabilities.

36. In a Continuous Integration (CI) pipeline, you run a script where a single Claude session generates a block of code and then immediately reviews its own changes in the same session.

Why is this considered an architectural anti-pattern?

The reviewer retains the reasoning context from the code generation phase, creating confirmation bias and reducing the likelihood of catching subtle issues.

It exceeds the maximum token limit for the context window, causing the session to silently truncate the generated code.

Same-session reviews trigger rate limiting automatically, breaking the CI/CD pipeline.

The Message Batches API does not support multi-turn tool calling within a single request.

37. You are building a customer support resolution agent using the Claude Agent SDK. The agent is currently escalating simple requests like password resets if the customer uses angry language.

How should you fix this escalation logic?

Lower the sentiment analysis threshold so that the agent only escalates if explicit profanity is detected.

Implement escalation based on objective criteria such as policy gaps, capability limits, or explicit human requests, rather than customer sentiment.

Issue an automatic partial refund to calm the customer down before processing the password reset.

Use a PreToolUse hook to normalize the customer's text input to a neutral tone before Claude processes it.

38. A developer needs to perform a monolith-to-microservices migration spanning 45+ files.

Why is Plan Mode recommended over Direct Execution for this task?

It uses the Message Batches API to reduce token costs by 50 percent during execution.

It enables safe codebase exploration and design to determine architectural approaches before making costly file modifications.

It automatically forks the session into a persistent subagent.

It bypasses the token limit context window by executing across multiple continuous sessions automatically.

39. A developer is using a multi-agent system to analyze a massive legacy codebase. The coordinator agent is running out of context window space because the search tool returns verbose file contents and exploration noise.

What is the best pattern to mitigate this context degradation?

Share the full coordinator conversation history with all subagents to ensure maximum context propagation.

Delegate the verbose file-by-file exploration to a subagent, which then returns only a synthesized summary of its findings back to the coordinator's context.

Force the coordinator agent to use the Bash tool to run grep manually instead of reading files.

Switch from dynamic adaptive decomposition to static prompt chaining to force a linear review path.

40. When designing JSON schemas for an extraction tool, why is it considered a best practice to define certain fields as optional or nullable (e.g., ["string’,' "null " J)? Choose 2 correct answers.

To prevent the model from fabricating or hallucinating values when the requested information is absent from the source document.

To ensure structural compliance without forcing the model to guess unknown values to satisfy required field constraints.

To trigger an automatic retry loop whenever the model returns a null value.

To bypass the tool_choice: " any" parameter constraint during execution.
