最新的 Claude Certified Architect CCAR-F 免費考試真題 (Q118-Q123):

問題 #118
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, Glob) and integrates with Model Context Protocol (MCP) servers.
During testing, you observe that in extended exploration sessions (30+ minutes), the agent starts giving inconsistent answers about code structure it discussed earlier. Engineers report having to repeat context about modules they've already explored. What's the most effective approach to address this?

A. Switch to a higher-capacity model tier to provide more context window space for accumulated exploration data.
B. Have the agent maintain a scratchpad file that records key findings, referencing it for subsequent questions.
C. Implement automatic context clearing every 15 minutes to ensure the agent starts with fresh, uncontaminated context.
D. Create summaries of all source files before exploration begins, loading only these compressed representations into context.

答案：B

解題說明：
Long exploration sessions fill the context window and degrade recall. A persistent scratchpad externalizes important architectural findings so the agent can re-read them instead of relying solely on increasingly crowded conversation context.

問題 #119
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 extracts event metadata (date, location, organizer, attendee_count) from news articles using a JSON schema with all nullable fields. During evaluation, you observe the model frequently generates plausible but incorrect values for fields not mentioned in the article--for example, outputting "500" for attendee_count when the source contains no attendance information.
What's the most effective way to reduce these false extractions?

A. Upgrade to a more capable model tier with improved instruction-following to reduce hallucination tendencies.
B. Add prompt instructions to return null for any field where information is not directly stated in the source.
C. Make all schema fields required (non-nullable) with strict validation rules to ensure the model only outputs verifiable data.
D. Add a post-processing step using a second LLM call to verify each extracted value exists in the source document.

答案：B

解題說明：
The schema already supports the correct representation of missing evidence: null. The remaining defect is behavioral. Claude must be explicitly instructed that absence of information is a valid outcome and that values may be populated only when directly supported by the supplied article.
Anthropic's hallucination-reduction guidance recommends explicitly permitting Claude to express uncertainty, grounding outputs in the source, and retracting claims that lack supporting evidence.
It also recommends restricting the model to the provided documents rather than allowing unsupported external knowledge. Option C translates those controls directly into the extraction contract: when no source evidence exists, the model returns null.

問題 #120
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.
You're implementing the escalation logic for when the agent should call escalate_to_human . Your team proposes four different approaches for triggering escalation.
Which approach will most reliably identify cases that genuinely require human intervention?

A. Build a rules engine that maps specific issue types, customer segments, and product categories to escalation decisions, removing the need for model judgment calls.
B. Instruct the agent to escalate when the customer requests a human, when the issue requires policy exceptions, or when the agent cannot make meaningful progress.
C. Implement sentiment analysis that monitors for frustration indicators (negative language, repeated questions, exclamation marks) and triggers escalation when the frustration score exceeds a configured threshold.
D. Configure the agent to escalate after three consecutive tool calls that fail to resolve the customer's stated issue, ensuring a reasonable attempt before involving a human.

答案：B

解題說明：
Option B identifies escalation through direct operational criteria rather than indirect proxies. A customer's explicit request for a person is unambiguous. A required policy exception defines an authorization boundary.
An inability to make meaningful progress identifies a case where continued autonomous execution is no longer productive.
Anthropic describes agents as systems that act, observe results, adjust, and continue until the task is completed or human input is required. Its trustworthy-agent guidance also emphasizes that agents must recognize when to pause rather than pushing through uncertainty or decisions that only a human can settle. (
https://www.anthropic.com/research/trustworthy-agents )
Option A is too rigid for high-ambiguity support cases. Maintaining exhaustive mappings for every issue, product, and customer segment recreates the brittleness that agentic reasoning is intended to avoid. Option C treats repeated tool use as a substitute for semantic progress; one definitive authorization failure may require immediate escalation, while several legitimate diagnostic calls may not. Option D confuses emotional tone with operational necessity. A calm customer may require a policy exception, while a frustrated customer may still have a straightforward automated resolution.
The escalation criteria should be encoded in the system instructions and supported by evaluations covering explicit requests, authorization limits, unresolved ambiguity, repeated non-progress, and successful self- service cases.
Official references/topics: Human-control checkpoints, escalation criteria, authorization boundaries, progress-aware agents.

問題 #121
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.
Production logs show that when the agent handles complex billing disputes requiring 6+ tool calls, it sometimes exhausts its max_turns limit after gathering data but before completing resolution or escalating.
The team's goal is to guarantee that every customer interaction ends with either a completed resolution or a human handoff, regardless of how the agent loop terminates.
Which approach achieves this guarantee?

A. Add orchestration-layer code that checks the agent's outcome after each loop termination-if the loop ended without a completed resolution or escalation, programmatically call escalate_to_human with the accumulated conversation context and tool results.
B. Add system prompt instructions telling the agent to call escalate_to_human with a summary of its findings whenever it determines it cannot complete resolution within its remaining actions.
C. Implement a pre-tool-use hook that counts tool invocations and terminates the loop with an automatic escalation once the agent reaches 80% of its max_turns limit.
D. Split the workflow into two sequential agent invocations-a first agent gathers information via get_customer and lookup_order, then a second agent receives that data and handles process_refund or escalate_to_human, each with separate turn budgets.

答案：A

解題說明：
Option C is the only approach that guarantees the required terminal condition independently of the model's behavior. When the agent loop stops, the orchestration layer evaluates the recorded outcome. If neither a successful resolution nor a confirmed human escalation occurred, deterministic application code invokes escalate_to_human using the information accumulated before termination.
The max_turns limit is a host-controlled safety boundary. Once that boundary is reached, the model may no longer have an opportunity to follow a prompt instruction or make another tool call. Therefore, the required fallback cannot depend entirely on Claude deciding to escalate before its remaining turns are exhausted.
Option A escalates based on an arbitrary 80% threshold and may prematurely terminate cases that could have been resolved successfully within the remaining budget. Option B provides additional turn capacity but does not guarantee that the second agent will complete its work or escalate before its own limit is reached. Option D remains probabilistic and cannot operate after an unexpected termination has already occurred.
The orchestration fallback should be idempotent, ensuring that repeated completion checks cannot create duplicate escalation records. It should also include verified customer information, relevant order data, completed actions, failure reasons, and the unresolved request in the handoff payload.
Official references/topics: Agent-loop termination, deterministic fallback orchestration, terminal-state validation, human handoff guarantees.

問題 #122
A retail organization observes that Claude occasionally gives different wording when summarizing identical customer reviews. The summaries remain accurate. What is the MOST likely explanation?

A. Claude is malfunctioning.
B. Large language models are probabilistic.
C. Retrieval failed.
D. The API returned cached responses.

答案：B

解題說明：
Claude generates text probabilistically, meaning multiple valid outputs may exist for the same prompt. Small wording differences are expected even when factual content remains consistent.
Lower temperature can improve consistency if deterministic outputs are preferred.
