最新的 Claude Certified Architect CCAR-F 免費考試真題 (Q125-Q130):

問題 #125
Production monitoring shows that follow-up queries like "summarize what we learned about market trends" consistently take 40+ seconds. Investigation reveals the coordinator spawns the synthesis subagent for each summarization request, passing 80K+ tokens of accumulated findings. The coordinator already has these findings in its context from orchestrating the research.
What's the most effective way to improve response time for these follow-up summaries?

A. Pre-generate and cache summaries at multiple granularities whenever new findings accumulate.
B. Enable prompt caching on the synthesis subagent to reduce the overhead of repeatedly transferring the same research findings.
C. Spawn the synthesis subagent with reduced context and have it request specific findings from the coordinator on-demand.
D. Have the coordinator handle straightforward summarization requests directly using its existing context, reserving subagent spawning for complex analysis.

答案：D

解題說明：
The coordinator already holds the accumulated findings and can perform simple summarizations directly. Avoiding repeated spawning of the synthesis subagent for straightforward queries reduces token processing and latency, improving response speed while maintaining accuracy.

問題 #126
You are integrating Claude Code into your Continuous Integration/Continuous Deployment (CI/CD) pipeline.
The system runs automated code reviews, generates test cases, and provides feedback on pull requests. You need to design prompts that provide actionable feedback and minimize false positives.
After deploying automated code review, developers report that approximately 35% of findings are false positives following consistent patterns: style suggestions that contradict team conventions, security warnings for patterns that are safe in the deployment environment, and performance suggestions that would degrade this particular use case.
You want to reduce false positives while enabling the model to generalize its judgment to novel code patterns it has not seen before.
Which approach is most effective?

A. Add general instructions telling Claude to be conservative and report only definite issues.
B. Use keyword-based post-processing to remove findings containing terms such as "convention,"
"context-dependent," or "trade-off."
C. Create a comprehensive specification of every pattern that must not be flagged and include the complete document in the system prompt.
D. Include few-shot examples containing annotated code snippets that distinguish acceptable project patterns from genuine issues in each category.

答案：D

解題說明：
Option B demonstrates the decision boundary Claude must learn. Carefully selected examples can show structurally similar code producing different outcomes based on project context-for example, an approved authentication wrapper versus an unsafe direct call, or a deliberate performance trade-off versus an accidental quadratic operation. These contrasts help Claude apply the underlying judgment to new code rather than merely memorizing prohibited phrases.
Anthropic identifies relevant, diverse, and clearly structured examples as one of the most reliable methods for improving output accuracy and consistency. It recommends several examples that mirror the real use case and cover important edge conditions. Option A risks creating an oversized negative catalogue that consumes context, becomes difficult to maintain, and cannot anticipate every future variation. Option C filters text after generation and may suppress genuine findings that happen to use the selected keywords. Option D is dangerously vague: telling a reviewer to be conservative can suppress real but uncertain defects and reduce recall. The prompt should provide paired acceptable/problematic examples, explain why each classification differs, and require concrete code evidence for every reported finding.

問題 #127
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.
Testing reveals that when source documents are missing certain specifications, the model fabricates plausible-sounding values to satisfy your schema's required fields. For example, a document mentioning only dimensions receives a fabricated "weight: 2.3 kg" in the extraction output.
What schema design change most effectively addresses this hallucination behavior?

A. Change fields that may not exist in source documents from required to optional, allowing the model to omit them.
B. Add explicit instructions to the prompt stating "only extract information explicitly stated in the document; use placeholder text for missing values."
C. Add a "confidence" field alongside each specification where the model self-reports its certainty, then filter out low-confidence extractions.
D. Implement semantic validation that verifies each extracted value appears in or can be inferred from the source document text.

答案：A

解題說明：
The schema is creating a structural incentive for fabrication. When a field is declared required, the output must contain a value even when the source document contains no corresponding evidence. Structured Outputs can guarantee that Claude's response conforms to a JSON Schema, but schema conformance does not establish that every generated value is factually supported. Anthropic's documentation shows that the required array determines which properties must be present; therefore, source-dependent properties that may legitimately be absent should not be included as required fields.
Option B corrects the problem at the contract level. Claude can omit the unavailable property rather than inventing content merely to produce valid JSON. A nullable representation could also be used when downstream systems require a stable key set, but forcing an unsupported non-null value is architecturally unsound.

問題 #128
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.
Monitoring shows 12% of extractions fail Pydantic validation with specific errors like "expected float for quantity, got `2 to 3'". Retrying these requests without modification produces identical failures.
What's the most effective approach to recover from these validation failures?

A. Send a follow-up request including the validation error, asking the model to correct its output.
B. Pre-process source documents to standardize problematic formats before sending them for extraction.
C. Implement a secondary pipeline using a larger model tier to reprocess documents that fail validation.
D. Set temperature to 0 to eliminate output variability and ensure consistent formatting.

答案：A

解題說明：
An unchanged retry repeats the same task specification and therefore commonly reproduces the same invalid interpretation. The validator has generated precise corrective information--quantity requires a float, but the model returned the range string 2 to 3. Supplying that error in a follow-up turn converts a generic retry into an iterative repair operation.
Anthropic identifies iterative refinement as a method for detecting and correcting inconsistencies by feeding an earlier output back into a subsequent request with targeted instructions. Option A applies that pattern directly. Claude receives the invalid output, the exact Pydantic error, and an instruction to return a schema-compliant correction. The application should cap retries, retain the original source, and escalate cases that cannot be represented without information loss.

問題 #129
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.
During testing, you observe that in extended exploration sessions lasting more than 30 minutes, the agent starts giving inconsistent answers about code structure it discussed earlier. Engineers report having to repeat context about modules they have already explored.
What is the most effective approach to address this?

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

答案：D

解題說明：
Option A moves durable, high-value discoveries outside the transient conversation history. The scratchpad should record module responsibilities, important symbols, architectural relationships, file paths, unresolved questions, and decisions supported by the code. The agent can reread this compact file after context compaction or before answering a later architectural question. Anthropic's large-codebase guidance recommends saving plans and important state to files because those artifacts survive when long conversations are compacted. Its context-management guidance also warns that accumulated file contents and command output can reduce performance during extended sessions.
Option B clears valuable information on a fixed schedule regardless of whether the current task is complete.
Option C delays the problem but does not prevent irrelevant history from crowding out important details.
Option D performs expensive summarization before the agent knows which files are relevant and may remove implementation details needed later. A focused scratchpad supports just-in-time restoration: the agent keeps the active context lean while retaining an auditable architectural map that can be updated as exploration progresses.
