Anthropic Claude Certified Architect - Foundations Sample Questions (Q46-Q51):

NEW QUESTION # 46
Your order management system requires tools for three distinct operations: issuing refunds (requires amount and reason), canceling orders (requires reason), and requesting reshipments (requires shipping address). Each operation shares an order_id parameter but has different additional requirements. You notice during testing that with your current unified tool design, the agent frequently omits required parameters or includes irrelevant ones. What design change will most effectively improve parameter accuracy?

A. Keep one unified tool with all parameters marked optional, but add detailed few-shot examples in the system prompt showing correct parameter combinations for each operation type.
B. Split into three separate tools (issue_refund, cancel_order, request_reshipment), each defining only the parameters required for that specific operation.
C. Keep one unified tool with a nested operation_details object parameter whose internal structure varies by operation type, documented in the tool description.
D. Keep one unified tool but add JSON Schema if-then-else conditionals to enforce that parameters like amount are required only when the operation type is "refund".

Answer: B

Explanation:
Separate tools with operation-specific schemas make the required parameters clear and reduce ambiguity during tool selection. This improves parameter accuracy because each tool exposes only the fields needed for that exact action, such as refund amount and reason, cancellation reason, or reshipment address.

NEW QUESTION # 47
Users report that final reports sometimes lack depth on specific subtopics. Investigation shows that the document-analysis agent frequently identifies evidence gaps-for example, noting that "the retrieved sources discuss API authentication but lack details about token-refresh patterns." Under the current strict pipeline, this insight is not actionable because searching has already finished. What is the most effective architectural change?

A. Have the coordinator look for general gap indicators in the analysis output and run additional searches without repeating the analysis stage.
B. Have the synthesis agent assign confidence scores to each report section and flag insufficiently supported sections for manual review.
C. Add a research-planning agent before the initial search phase to decompose every topic into detailed subquestions.
D. Require the analysis agent to return specific evidence gaps to the coordinator, which launches targeted searches and invokes analysis again until the defined coverage criteria are satisfied.

Answer: D

Explanation:
Option C converts the linear pipeline into a controlled iterative research loop. The document-analysis agent is best positioned to identify precisely what the retrieved evidence fails to answer. It should return structured gaps containing the missing question, evidence already examined, preferred source characteristics, and the coverage criterion that remains unsatisfied. The coordinator can then issue focused searches and resubmit the new material for analysis.
Anthropic's multi-agent research architecture uses a lead agent to decompose work, coordinate research agents, assess returned information, and continue investigation when further evidence is required. The guidance also stresses clear objectives, output formats, source requirements, and task boundaries to prevent gaps and duplicated work.
Option A may improve initial coverage but cannot anticipate every deficiency revealed only after sources are examined. Option B documents incompleteness rather than correcting it. Option D retrieves more information but does not ensure that the new evidence is analyzed and tested against the original gap. The loop in Option C establishes an explicit completion condition and preserves specialization: analysis identifies the gap, the coordinator orchestrates, search agents retrieve evidence, and analysis verifies whether the gap has actually been closed.

NEW QUESTION # 48
You are building developer-productivity tools using the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive tasks. It uses the built-in tools-Read, Write, Bash, Grep, and Glob-and integrates with Model Context Protocol (MCP) servers.
Your productivity agent connects to three MCP servers: an issue tracker with search_issues , get_issue , and create_comment ; a documentation wiki with search_docs , get_page , and list_spaces ; and a database explorer with run_query , get_schema , and list_databases . For cross-system questions such as, "Which database tables are affected by the authentication refactor in PROJ-1234?", the agent makes eight to ten sequential exploratory calls, lacks visibility into each server's available content, and exhausts context before completing complex investigations.
What architectural change best leverages MCP capabilities to address these problems?

A. Consolidate all three systems into one unified MCP server with cross-referencing capabilities.
B. Add an orchestrator that routes each question to one server based on keywords.
C. Expose each server's content catalog as MCP resources, including issue summaries, documentation hierarchies, and database schemas.
D. Add a prepare_investigation tool to each server that accepts a natural-language question and returns relevant summaries.

Answer: C

Explanation:
Option C uses MCP resources for their intended purpose: exposing contextual data that applications and agents can discover and read without treating every lookup as an action-oriented tool invocation. Anthropic's Claude Code MCP documentation states that Claude Code automatically provides mechanisms to list and read resources exposed by connected MCP servers. Resources may contain text, JSON, structured data, or other server-provided content. The official MCP server concepts likewise explain that resources expose information from files, APIs, and databases through identifiable, discoverable URIs. Publishing issue summaries, the wiki hierarchy, and database schemas gives the agent an initial map of available evidence. It can identify relevant systems and retrieve only the necessary records before making targeted tool calls. Option A creates another opaque, high-level tool whose output quality depends on each server interpreting the investigation correctly.
Option B produces tight coupling and increases operational complexity. Option D prevents the cross-system investigation required by the question. Resource catalogs improve discoverability, reduce blind exploration, and preserve tools for searches, queries, and mutations that genuinely require execution.

NEW QUESTION # 49
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 system has been running for 3 weeks and human reviewers have corrected 847 extractions.
Analysis reveals a recurring pattern: when recipes use informal measurements like "a handful" or
"a splash," the model either invents specific amounts or leaves fields empty--accounting for 23% of all corrections.
How should you use this feedback to improve extraction accuracy?

A. Fine-tune the model on the 847 corrected extractions.
B. Implement a post-processing layer that uses pattern matching to detect informal measurement phrases in source text and automatically populate values when the extraction is empty.
C. Add few-shot examples to your prompt demonstrating correct handling of informal measurements--extracting them verbatim rather than converting or omitting them.
D. Update your JSON schema to add a "measurement_type" enum field (precise/informal).

Answer: C

Explanation:
The reviewer corrections have exposed a narrow and repeatable interpretation failure. The desired policy is clear: informal measurements are valid source values and must be preserved verbatim rather than normalized into invented quantities or treated as missing. This behavior can be communicated efficiently through targeted few-shot examples.
Anthropic recommends examples for demonstrating expected behavior and improving consistency. Examples can pair source phrases such as "a handful of spinach," "a splash of vinegar," and "a pinch of salt" with outputs that retain handful, splash, and pinch exactly.
Additional counterexamples can show that Claude must not convert these phrases into grams, millilitres, or estimated serving quantities.

NEW QUESTION # 50
You are building a customer support resolution agent using the Claude Agent SDK. The agent handles high- ambiguity requests like returns, billing disputes, and account issues. It has access to your backend systems through custom Model Context Protocol (MCP) tools ( get_customer , lookup_order , process_refund , escalate_to_human ). Your target is 80%+ first-contact resolution while knowing when to escalate.
During testing, you find that when a customer says "I need a refund for my recent purchase," the agent calls process_refund immediately-but populates the required order_id parameter with a plausible-looking but fabricated value instead of first calling lookup_order to retrieve the actual order ID. The refund call fails because the fabricated ID doesn't exist.
Which change directly addresses the root cause of the agent fabricating the order_id value?

A. Switch tool_choice from "auto" to "any" to force the agent to make a tool call on every turn.
B. Add server-side validation that checks whether the order_id exists in your database before executing the refund, returning an error to the agent if not found.
C. Update the process_refund tool description to explicitly state that order_id must be obtained from a prior lookup_order call and must never be assumed or invented.
D. Pre-parse incoming customer messages to extract any order IDs mentioned, and inject them into the conversation context before passing to Claude.

Answer: C

Explanation:
The root cause is an incomplete tool contract. Claude sees that process_refund requires an order_id , but the tool description does not explain the parameter's trusted source or the prerequisite lookup sequence. Option A makes the dependency explicit and prohibits fabricated values.
Anthropic states that tool descriptions should explain what a tool does, when it should be used, how it behaves, and any important limitations. Its prompting guidance also states that dependent tool calls must be executed sequentially and that Claude must never use placeholders or guess missing tool parameters. (
https://platform.claude.com/docs/en/agents-and-tools/tool-use/define-tools ) Option B merely forces some tool use; it does not force the correct tool or prevent a fabricated identifier.
Option C is an essential defense-in-depth control, but it detects the invalid ID after the model has already made the faulty call. It does not correct the selection logic that caused the fabrication. Option D works only when the customer actually provides an identifier and introduces an unnecessary preprocessing dependency.
The process_refund schema should describe order_id as a verified identifier returned by lookup_order , and the tool description should state that the tool is unavailable until the corresponding order has been retrieved and eligibility established.
Official references/topics: Tool descriptions, prerequisite tool calls, parameter provenance, sequential tool orchestration.
