You are compiling a diagnostic toolkit for Claude Code operational issues.
Which two diagnostic actions belong in the toolkit? (Select two.)
Each correct answer presents a complete solution.

• A. Increase the model sampling temperature so that intermittent issues surface more frequently for analysis.
• B. File a support ticket with vendor support before any local reproduction or evidence collection.
• C. Roll back to the previous Claude Code version immediately to confirm whether the issue is version specific.
• D. List the configured Model Context Protocol (MCP) servers and inspect server status to identify connection failures.
• E. Reproduce the issue with a minimal reproduction case that isolates one variable at a time.

You are compiling continuity practices that span the deployment lifecycle.
Which two practices belong on the list? (Select two.)
Each correct answer presents a complete solution.

• A. Capture lessons learned at the end of each phase and surface them as inputs to the next phase.
• B. Archive every phase deliverable in long-term storage to preserve a record of what was produced.
• C. Maintain a stakeholder register and notify the listed parties at every phase transition event.
• D. Carry the evaluation framework and reference set forward across iterations rather than rebuilding each time.
• E. Lock decisions made in early phases to prevent revisiting them as later phases begin.

You are supporting a team whose Claude Code sessions consistently load 60 or more MCP tools from many servers, exhausting context budget before the session begins.
Which adjustment most directly addresses this issue without removing capability?

• A. Add additional MCP servers to give the team more capability, which increases rather than reduces the number of tool definitions loaded into the session's context budget.
• B. Enable Tool Search so tool definitions are deferred and discovered on demand rather than loaded into context upfront.
• C. Increase the prompt's verbosity with additional instructions and context, which consumes more of the context budget rather than reducing the tool-definition overhead causing the issue.
• D. Disable every MCP server in the configuration to free up context budget, accepting that the team loses all tool access and cannot perform any MCP-dependent task in the session.

You are assessing a Claude-based system whose dominant risk is silent quality drift on safety-relevant outputs after a model-version upgrade.
Which assessment activity most directly addresses this risk?

• A. Maintain an adversarial evaluation set with version-attributed scoring so each upgrade is measured against the same set before promotion.
• B. Skip evaluation on each model-version upgrade and rely on user-submitted complaints to surface safety drift after the upgraded model has already served production traffic.
• C. Rotate adversarial inputs randomly so no two upgrades are scored on the same set.
• D. Disable adversarial evaluation entirely during model-version upgrade cycles to reduce evaluation cost, accepting that safety drift will go undetected until it appears in production.
