You are running a controlled experiment to compare two prompts and must complete the design steps before executing the experiment.
Which two steps must be completed BEFORE running the experiment with random assignment? (Select two.) Each correct answer presents part of the solution.

• A. Analyze the results against the predefined success metric and significance threshold.
• B. Define the hypothesis and the primary success metric for the comparison.
• C. Decide whether to promote, reject, or iterate the candidate based on the analysis.
• D. Determine the minimum detectable effect size and the sample size needed for power.
• E. Document the recommendation, the trade-offs accepted, and the alternatives considered.

A Claude architect needs to ensure that a security-hardening flag cannot be disabled by any individual engineer after it is set.
Which configuration scope correctly enforces this requirement?

• A. User scope (~/.claude/settings.json) on each engineer's machine
• B. Project scope (.claude/settings.json) committed to the repository
• C. Environment variable defined in the CI/CD pipeline only
• D. Managed configuration applied centrally and marked as non-overridable

An operations engineer reports that a Claude-based pipeline began returning malformed JSON responses after a scheduled maintenance window, causing downstream processing failures.
Which two investigative steps most directly isolate the root cause? (Select two.)

• A. Clear the prompt cache and resubmit all pending requests to eliminate stale cached prefixes.
• B. Compare the current system prompt and output schema configuration against the last known good version from before the maintenance window.
• C. Increase the max_tokens limit to determine whether output truncation is causing incomplete JSON structures.
• D. Switch to a different Claude model tier to rule out provider-side changes as a contributing factor.
• E. Replay a set of premaintenance requests against the current configuration and inspect the raw model output before downstream parsing.

You are designing a feedback session for a deployment in flight.
Which structure best supports productive stakeholder feedback?

• A. End the session without recording decisions, follow-up items, action owners, or dates, relying on participant memory to carry the session's outcomes forward.
• B. Define a focused agenda, share the artifacts in advance, capture decisions and follow-ups in writing, and confirm action owners and dates.
• C. Hold an open-ended meeting with no pre-distributed agenda or artifacts, and rely on participants' memory to carry decisions and follow-up owners forward.
• D. Distribute artifacts at the session start rather than in advance, so stakeholders review materials in real time without preparation before the discussion begins.

Engineering leadership wants to roll out Claude Skills to 280 developers across 14 teams. Skills will encode internal coding standards, code-review checklists, and incident-postmortem templates. Leadership has asked how to govern Skill authorship so that Skills remain trustworthy without bottlenecking on a single central team.
Which governance model should you recommend?

• A. Federated authorship across the 14 teams with a central review and publication gate.
• B. Per-developer authorship across the 280 engineers with no team-level coordination required.
• C. Fully decentralized authorship across the 14 teams with no review before publication.
• D. Centralized authorship by a single platform team responsible for every Skill produced.
