Anthropic Claude Certified Architect - Foundations Sample Questions (Q30-Q35):

NEW QUESTION # 30
You are building a structured data extraction system using Claude. The system extracts information from unstructured documents, validates the output using JSON schemas, and maintains high accuracy. It must handle edge cases gracefully and integrate with downstream systems.
Your extraction uses tool use with a JSON schema in which property_type is defined as an enum: house, apartment, condo, or townhouse. After deployment, 8% of extractions fail schema validation. Investigation reveals that listings mention many uncommon property types-"studio," "loft," "duplex," "mobile home,"
"tiny house," and "converted warehouse"-and new types continue appearing regularly.
What is the most effective long-term solution?

A. Add an other value to the enum with a separate property_type_detail string field for specifics when other is selected.
B. Change property_type from an enum to a free-form string and implement a normalization step in post- processing.
C. Continuously expand the enum to include newly observed property types and add monitoring for additional edge cases.
D. Add few-shot examples demonstrating how to map unexpected property types to the closest existing enum value.

Answer: B

Explanation:
Option A is the most sustainable open-world design. The property-type domain is demonstrably not closed:
uncommon values already occur, and new labels continue to appear. An enum is appropriate only when the valid vocabulary is stable and exhaustive. If the source contains a legitimate value outside that vocabulary, the schema either rejects it or pressures the model to map it inaccurately. A free-form string preserves the source meaning, while deterministic post-processing can normalize "studio," "loft," "duplex," and future terms into an evolving canonical taxonomy. Anthropic's Structured Outputs documentation distinguishes structural schema conformance from the semantic decisions made within that schema; it also documents that JSON Schema constraints such as enums govern allowable output shapes and values. Few-shot mapping to the nearest existing enum, option B, discards real distinctions. Continually expanding the enum, option C, creates recurring schema changes and still lags newly observed values. An "other" bucket with detail, option D, is workable but collapses all emerging categories at the primary field and complicates analytics until downstream interpretation occurs. Capturing the raw type first and normalizing it in code provides lossless extraction, testable mappings, and forward compatibility.

NEW QUESTION # 31
You are building a structured data extraction system using Claude. The system extracts information from unstructured documents, validates the output using JavaScript Object Notation (JSON) schemas, and maintains high accuracy. It must handle edge cases gracefully and integrate with downstream systems.
Your pipeline uses a tool called extract_metadata with a JSON schema for paper details. You've also defined lookup_citations and verify_doi tools for enrichment. During testing, you notice that when users include requests like "extract the metadata and tell me how cited it is," Claude sometimes calls lookup_citations first, which fails because it needs the DOI that extract_metadata would provide.
What's the most effective way to ensure structured metadata extraction happens first?

A. Set tool_choice to {"type": "tool", "name": "extract_metadata"} for every API call in the pipeline, ensuring Claude always extracts metadata before any enrichment can occur.
B. Set tool_choice to "any" so Claude must use a tool, combined with system prompt instructions prioritizing extract_metadata .
C. Set tool_choice to "auto" and reorder the tool definitions so extract_metadata appears first in the tools array, since Claude prioritizes earlier-listed tools.
D. Set tool_choice to {"type": "tool", "name": "extract_metadata"} and process the enrichment requests in subsequent turns after receiving the extracted metadata.

Answer: D

Explanation:
The dependency must be enforced by orchestration rather than left to probabilistic tool selection. Anthropic documents that tool_choice: {"type": "tool", "name": "..."} forces Claude to invoke the specified tool. By contrast, auto allows Claude to decide whether and which tool to call, while any requires some tool but does not force a particular one. ( https://platform.claude.com/docs/en/agents-and-tools/tool-use/define-tools ) Option A therefore establishes a deterministic two-stage workflow. The first API turn forces extract_metadata
, producing the DOI and other structured paper details. The application validates and stores that result. A subsequent turn then exposes or permits verify_doi and lookup_citations , passing the extracted DOI as explicit state. This design converts an implicit tool dependency into an application-controlled execution graph.
Option B is incorrect because array order is not a documented precedence mechanism and cannot guarantee selection. Option C forces extract_metadata on every call, including turns where enrichment should occur, potentially creating an infinite or non-progressing workflow. Option D guarantees only that one available tool is called; Claude could still select lookup_citations before the DOI exists.
For stronger input integrity, the tools can also use strict schemas so their arguments conform to the declared JSON Schema. The sequencing requirement, however, remains the responsibility of the orchestration layer.

NEW QUESTION # 32
Your multi-agent research pipeline crashed after processing12 of 28 documents. The web search agent had identified relevant sources, the document analyzer had partially completed extraction, and the synthesizer had begun pattern identification. You need to resume processing without repeating work or losing fidelity of prior findings. What state management approach best balances information fidelity with context efficiency when restoring agent state?

A. Have each agent persist a structured export to a known location. On resume, the coordinator loads the manifest and injects relevant state into agent prompts.
B. Index all agent outputs in a shared vector store. When resuming, each agent queries the store using semantic search to retrieve relevant prior findings.
C. Have each agent maintain its own persistent state file and reload it independently at the start of each session.
D. Persist the coordinator's conversation log containing all task delegations and responses, providing this to agents when resuming.

Answer: A

Explanation:
Persisting structured exports and a coordinator manifest preserves completed work in a reliable, resumable format. On recovery, the coordinator can reload only the relevant state for each agent, avoiding repeated processing while maintaining fidelity of prior findings without flooding prompts with full conversation logs.

NEW QUESTION # 33
You are building a multi-agent research system using the Claude Agent SDK. A coordinator agent delegates to specialized subagents: one searches the web, one analyzes documents, one synthesizes findings, and one generates reports. The system researches topics and produces comprehensive, cited reports.
The synthesis agent completes its initial pass but flags that three key research questions remain unanswered because the web-search and document-analysis agents did not find relevant information on those specific subtopics. The coordinator currently proceeds directly to report generation, producing reports with incomplete coverage.
What change would most effectively improve research completeness?

A. Increase the initial breadth of queries sent to web search and document analysis to reduce the probability of missing relevant information.
B. Give the synthesis agent direct access to web-search tools so it can autonomously fill knowledge gaps without returning control to the coordinator.
C. Have the report-generation agent note which research questions could not be answered, so users understand the limitations of the final output.
D. Have the coordinator evaluate the synthesis output for gaps, then re-delegate to web search and document analysis with targeted queries before invoking synthesis again.

Answer: D

Explanation:
Option B introduces an evaluator-and-refinement loop at the correct orchestration layer. The coordinator already owns the research plan and delegation decisions, so it should inspect the synthesis result against the required questions, identify coverage gaps, and issue focused follow-up assignments. Anthropic's description of its multi-agent research system follows this pattern: the lead agent synthesizes returned findings, determines whether additional research is required, and creates new subagents or refines its strategy before producing the final result. Increasing the initial query breadth, option A, may generate additional irrelevant material and cannot guarantee that unforeseen gaps will be covered. Option C merely documents the incompleteness instead of correcting it. Option D weakens role separation by giving the synthesis agent search capabilities, increasing tool complexity and bypassing the coordinator's centralized tracking. Targeted re- delegation preserves specialized responsibilities and creates an observable sequence of research, evaluation, refinement, and resynthesis. The coordinator should also maintain explicit coverage criteria and limit the number of refinement rounds so the system improves completeness without entering an uncontrolled research loop.

NEW QUESTION # 34
Your automated review generates many findings per pull request, but developer feedback shows that roughly half are dismissed as "not worth addressing." Analysis reveals that dismissed findings are often technically accurate but involve minor style preferences or patterns that are acceptable in your codebase. Before adding infrastructure complexity, what prompt-design change could most effectively reduce dismissals while maintaining the detection of genuine issues?

A. Implement a secondary classification model that filters Claude's findings according to predicted developer acceptance.
B. Append instructions telling Claude to "only report findings you are highly confident are genuine problems."
C. Add explicit criteria defining which issues to report, such as bugs and security defects, and which issues to skip, such as minor style preferences and accepted local patterns.
D. Ask Claude to rate every finding's confidence from 1 to 10 and include only findings rated 8 or higher.

Answer: C

Explanation:
The problem is an undefined relevance threshold. Claude is finding technically valid observations, but the prompt does not clearly distinguish actionable defects from acceptable conventions and low-value style preferences. Option A establishes explicit positive and negative reporting criteria, allowing the model to apply the team's actual definition of a useful finding during generation.
Anthropic's prompt-engineering guidance emphasizes clear, specific instructions and well-defined success criteria. The managed Code Review documentation similarly recommends defining skipped categories, generated paths, severity rules, and evidence requirements. Reporting "bugs affecting correctness or security" while excluding "formatting handled by CI and documented local conventions" is substantially more precise than asking the model to be generally conservative.
