QUESTION NO: 1
You are setting up the configuration management approach for a new Claude Code project. Your team will use CLAUDE.md files and settings.json files to control behavior, and you want to make sure changes are tracked and reviewable.
The configuration management approach would...

A. Version-control CLAUDE.md and settings.json files in a separate repository from the project's source code, so configuration evolves independently from the application code over time. B. Duplicate CLAUDE.md and settings.json files in multiple repositories to provide redundancy, on the grounds that a single source of truth is risky for project configuration. C. Version-control CLAUDE.md and settings.json files alongside the project's source code, with changes reviewed through standard pull request workflows the team applies. D. Version-control CLAUDE.md alongside the project's source code and settings.json files in a separate repository from the project's source code.

QUESTION NO: 2
Your Claude application's error handling currently logs every API error with the same severity level. The team wants to differentiate between errors that should page an on-call engineer and errors that should be logged for later review. How would you structure the error handling?

A. Categorize errors by severity based on impact and recoverability, then route each category to the appropriate channel for paging or logging. B. Disable logging for any error that does not page, treating non-paging errors as not worth recording for later review either. C. Page on every error, on the grounds that paging guarantees that no error is missed by the team during normal operation across the application's lifecycle. D. Log every error with the same severity, on the grounds that differentiating severity adds complexity that does not pay off in most application setups over time.

QUESTION NO: 3
You are building an MCP server that exposes several internal data sources as MCP resources. The server needs to be deployed so multiple Claude applications can integrate with it.
How would you approach the build and deployment?

A. Bypass the MCP server and embed each data source directly in every Claude application that needs the data, with each application maintaining its own integration. B. Deploy the MCP server only on individual developer machines, with the Claude applications unable to reach the server outside each developer's machine. C. Author the server with clearly defined resources, tools, and prompts, choose a communication pattern, and deploy to an accessible hosting environment. D. Build the MCP server with resource and tool definitions scoped to the first Claude application that needs it, and extend the definitions to additional applications as each integration is requested.

QUESTION NO: 4
A new Claude model release includes performance improvements for several reasoning tasks but has changed the format of its responses to system prompts that use multi-section instructions. Your application uses multi- section system prompts heavily. Initial evaluation on the application's actual workload shows the new model performs 8 percent better on reasoning tasks but produces malformed output on roughly 3 percent of requests because of the format change. The team is debating whether to upgrade.
How would you decide?

A. Adapt the application's system prompt to the new model's format expectations and re-evaluate, then upgrade only if the adapted prompt eliminates the malformed output while preserving the reasoning improvements. B. Upgrade and add a downstream validation step that catches the 3 percent malformed output before it reaches users, treating the validation step as the team's mitigation for the format change. C. Stay on the previous model permanently to avoid the malformed output rate and any future format changes that subsequent model releases might introduce in the application. D. Upgrade immediately, because the 8 percent reasoning improvement outweighs the 3 percent malformed output rate across the application's typical request distribution.

QUESTION NO: 5
You are setting up Claude Code for a new project repository. Your team has shared coding standards, preferred libraries, and project-specific context that every developer working on the repository should have available when they use Claude Code.
How would you set this up?

A. Initialize Claude Code in the repository and document the standards and project-specific context in a CLAUDE.md file at the repository root. B. Add the coding standards and project context to the repository's existing README file and direct developers to reference it when starting Claude Code sessions. C. Configure Claude Code through environment variables that each developer sets on their own machine when they begin working in the repository. D. Document the standards in a separate wiki page maintained outside the repository so the documentation stays decoupled from the source code.

QUESTION NO: 6
Your team is preparing a new Claude application for production, and the product team has asked for a cost projection. The team needs to estimate the cost based on expected request volume, average input length, and average output length. How would you build the projection?

A. Build a cost model based on expected request volume and the chosen model's pricing, treating average input and output token counts as variables to be estimated post-launch. B. Build a cost model that combines expected request volume and average input tokens, treating output tokens as a small enough share of cost to leave out of the projection. C. Build a cost model that combines expected request volume, average input tokens, average output tokens, the chosen model's pricing, and any caching benefits. D. Build a cost model that uses the average per-request cost from a similar Claude application the team built last year, scaling that figure by expected request volume.

QUESTION NO: 7
Your team's Claude agent has accumulated several customizations that bypass the SDK's defaults, including custom history management, retry logic, and error handling. A new team member has proposed reverting all the customizations to maintain the codebase more easily. The tech lead disagrees and says each customization was added for a reason.
How would you advise the team?

A. Revert all customizations to the SDK's defaults to standardize the codebase. B. Decide on each customization individually based on its original reason and the SDK's current capabilities. C. Migrate the agent off the SDK and rebuild it with a custom loop. D. Keep all customizations, trusting that the tech lead's original reasoning is still valid.

QUESTION NO: 8
A teammate is reviewing the team's threat model for a Claude application and has asked you to identify the categories of AI-specific threats that the model should cover. The teammate has already listed traditional web application threats and wants to know what additional categories apply to a Claude application.
Which AI-specific threat categories would you add?

A. Network-level denial of service and physical infrastructure attacks, because these categories cover the threats most likely to affect any Claude application in production. B. Supply chain attacks on the Claude SDK because the SDK itself is the only point of vulnerability that a Claude application introduces beyond traditional web application threats. C. Cross-site scripting and SQL injection, because these traditional web application threats apply with equal weight to any application that uses Claude in any way. D. Prompt injection, data leakage from prompts or context, jailbreak attempts, and unsafe model output that bypasses application controls.

QUESTION NO: 9
Your Claude agent's hooks are currently triggered for every action, which slows down the agent significantly even when actions pose no risk. The team wants to scope hooks more carefully.
How would you scope the hooks?

A. Disable the agent during peak hours so the hook overhead does not slow the application down during the busiest periods of the day across the application's operation. B. Replace hooks with system prompt instructions on the grounds that prompt instructions can produce the same enforcement effect that hooks produce on the agent's actions. C. Scope hooks to only the high-risk actions, such as destructive operations or sensitive data access, and remove hooks from low-risk actions to balance safety with performance. D. Disable all hooks while the team re-scopes them, treating the period of no hook enforcement as a temporary state during the re-scoping work.

QUESTION NO: 10
Your Claude application requests structured JSON output from the model. Most of the time the JSON is well- formed, but occasionally Claude returns malformed JSON that breaks downstream processing.
How would you handle the malformed output?

A. Switch to free-form text output so the application no longer depends on JSON parsing for any of the responses it sends to downstream systems during normal operation. B. Retry the same request repeatedly until valid JSON appears in the model's response, with the retry loop adding delay to the application's response time on affected requests. C. Manually inspect every response before downstream processing so a human reviewer catches any malformed JSON before the application passes the response to downstream systems. D. Add output validation that parses Claude's response against the expected schema and treats malformed output as a recognized error path with retry or fallback handling.
