You are designing a Claude application that helps medical researchers analyze multi-step clinical case studies.
The application must work through differential diagnoses by considering symptom patterns, weighing evidence across competing hypotheses, and showing intermediate reasoning steps before producing a final recommendation. The team is choosing among Claude's available model options.
The model option best suited to this use case is...

• A. Zero-shot prompting alone with no model option adjustments, which keeps the application's configuration as simple as possible.
• B. A smaller model with a tighter context window, which encourages the model to focus its limited capacity on the task.
• C. Extended thinking, which lets the model reason through the differential diagnosis steps before producing the final recommendation.
• D. Fast mode, which prioritizes the lowest possible latency at the expense of reasoning depth on complex tasks.

You are choosing between using STDIO-based communication and HTTP-based communication for an MCP server. The server will be invoked by a Claude Code session running locally.
Which communication pattern would you use?

• A. HTTP polling against the MCP server, treating HTTP as a substitute for the standard MCP communication patterns.
• B. HTTP on the grounds that HTTP is preferable to STDIO in any context the application might encounter during normal operation.
• C. STDIO because STDIO is well-suited to local process communication and avoids unnecessary network setup.
• D. STDIO and HTTP simultaneously for redundancy, with the team running two communication patterns at the same time across Claude Code sessions.

A new agent your team built handles customer support tickets, but it routinely gets confused when a single ticket spans billing, shipping, and product issues. The agent often loses track of which sub-issue it has already addressed and revisits the same one. The team is considering architectural changes.
What architectural change would you recommend?

• A. Add detailed prompting that instructs the agent to track which sub-issues have been resolved and which remain.
• B. Introduce an orchestrator agent that delegates billing, shipping, and product sub-issues to dedicated subagents.
• C. Increase the size of the agent's context window so it can hold the full ticket history at once.
• D. Switch to a deterministic workflow that handles billing, shipping, and product issues in a fixed sequence.

You are building a Claude application that needs to deliver model output to end users as it is generated, instead of waiting for the full response to complete.
The Claude API mechanism you would use is...

• A. Prompt caching, which speeds up the cost profile of future requests and does not affect the delivery timing of the first response.
• B. The Batch API, which delivers full responses after a delay suitable for non-interactive workloads.
• C. Streaming responses, which deliver tokens incrementally as the model generates them so users see output progressively.
• D. Structured JSON output, which delivers responses only after the model has finalized the JSON shape across the entire response.
