Claude Certified Architect - Professional v1.0

You are an architect supporting the iteration phase of a deployed Claude-based system.
Which activity most directly fits this phase?

A Claude architect at a health services organization is defining evaluation metrics for a clinical-summary pipeline. The pipeline must remain within a per query cost ceiling and must never surface patient data to unauthorized roles.
Which two metrics directly address these requirements? (Choose two.)

A revenue projection assistant has missed its monthly cost target by 38 percent. Profiling shows three contributors: a 6,000-token policy preamble repeated on every call (45 percent of cost), retrieval of historical sales chunks averaging 3,000 tokens per call (30 percent), and inference on a flagship tier model (25 percent). Stakeholders require that projection accuracy remain unchanged.
Which two optimizations should you sequence first to reduce cost without affecting accuracy? (Choose two.)
Each correct answer presents part of the solution.

You are operating an interactive assistant whose dominant performance constraint is per-turn latency. Quality on routine turns is already acceptable.
Which configuration adjustment most directly improves latency without disproportionately damaging quality?

You are evaluating an evaluation set used to score a Claude-based hiring-support tool. The set is drawn from one geographic region and one tenure band.
Which response is most appropriate?

You are reviewing instrumentation in a multi-agent system.
Which two findings constitute valid observability gaps in the instrumentation? (Choose two.)
Each correct answer presents a complete solution.

You are building an evaluation pipeline for a Claude-based deployment and must complete the specification steps before running the deployment against the dataset.
Which two steps must be completed BEFORE running the deployment against the evaluation dataset? (Choose two.)
Each correct answer presents part of the solution.

You are identifying the highest-impact optimization for a deployment whose token cost is dominated by a long, repeated system prompt and a large retrieved context per request.
Which optimization most directly targets the dominant cost driver?

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? (Choose two.)

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? (Choose two.)
Each correct answer presents part of the solution.

An architect is reviewing a Claude-based candidate-screening tool prior to deployment. A stakeholder asserts that because the model was not trained on company data, no bias evaluation is necessary.
Which two responses most accurately challenge this assertion? (Choose two.)

You are building an ethics review checklist for deployments supported by artificial intelligence (AI).
Which two checks belong on the list? (Choose two.)
Each correct answer presents a complete solution.

You are defining where human review must remain in a planned automated pipeline.
Which placement reflects sound human-in-the-loop design?

An engineer inadvertently commits an API key to the repository by placing it in .claude/settings.json.
Which configuration design principle was violated?
