Anthropic CCA-F Sample Question Answers
Question # 1
A developer implements compaction for a long-running code review session. After compaction, Claudeloses track of files it already reviewed and re-reviews them. What technique preserves the reviewprogress through compaction?
A. Use custom compaction instructions: 'Always preserve the list of reviewed files and their review
status' B. Maintain a scratchpad file (e.g., REVIEW_PROGRESS.md) listing completed reviews, with Claude
reading it after compaction to restore state C. Increase the compaction summary length to capture all reviewed files D. Disable compaction and manage context manually
Answer : A
Explanation:
Custom compaction instructions ensure the summarizer explicitly preserves the review state. By
instructing compaction to maintain the list of reviewed files and their status, this information persists
through summarization without requiring external files. Option A may not be configurable to target
specific content. Option B works but adds file I/O overhead. Option D is fragile for long sessions.
Question # 2
A startup is designing a customer service agent. They want the agent to detect when a customer isfrustrated based on conversation patterns (multiple repeated questions, escalating language, long waittimes). The detection should trigger a different handling workflow. Where should frustration detectionlogic be implemented?
A. In the system prompt: 'Detect frustration and adjust your approach' B. In a PostToolUse hook that monitors the conversation for frustration indicators C. As a separate sentiment analysis tool that the agent calls periodically D. In the orchestrator as a classifier that analyzes each customer message and adjusts the agent's system
prompt or routing based on sentiment signals
Answer : D
Explanation:
The orchestrator is the appropriate layer for cross-cutting concerns like sentiment analysis. Analyzing
each customer message through a lightweight classifier enables dynamic adjustments: updating the
system prompt tone, routing to a specialized empathy-focused agent, or triggering human handoff.
Option A relies on the agent self-detecting. Option C adds tool call overhead. Option D only monitors
tool interactions.
Question # 3
A team implements a structured output pipeline where Claude generates quiz questions. Each questionmust have exactly 4 options and one correct answer. They use json_schema strict mode. Occasionally,two options are semantically identical (e.g., 'Use a load balancer' and 'Implement load balancing'). Theschema can't prevent this. What additional quality measure is needed?
A. Add a schema constraint for unique options (uniqueItems in JSON Schema) B. Implement a semantic similarity check in the application layer that compares all option pairs and
flags near-duplicates for regeneration C. Use extended thinking to encourage Claude to verify distinctness before generating D. Add a system prompt instruction: 'All options must be semantically distinct'
Answer : B
Explanation:
Schema validation can enforce syntactic uniqueness (Option A) but not semantic uniqueness. A
semantic similarity check using embedding comparison catches near-duplicate options like 'Use a load
balancer' vs 'Implement load balancing'. This application-layer validation complements the schema
enforcement. Option B may help but isn't reliable. Option D is guidance without enforcement.
Question # 4
Your organization is designing a prompt caching strategy. Their application has: (1) a 3K token systemprompt, (2) a 10K token knowledge base, (3) a 2K token conversation history, and (4) user messagesaveraging 200 tokens. They're using Claude Sonnet 4.5 which has a minimum 1024 token cachethreshold. Which portions should be cached?
A. System prompt (3K) + knowledge base (10K) as a single cached prefix, since both are stable and
together form a 13K prefix well above the minimum threshold B. Only the system prompt (3K) since it's stable across all requests C. Cache everything including conversation history D. Only the knowledge base since it's the largest component
Answer : A
Explanation:
The system prompt and knowledge base together form a stable 13K token prefix that's shared across all
requests and well above the 1024 token minimum for Sonnet 4.5. Conversation history changes per
turn (Option C) making it uncacheable across requests. The system prompt alone (Option A) misses the
larger savings from the knowledge base. Option D wouldn't include the system prompt prefix.
Question # 5
A developer creates an MCP tool that wraps a SOAP-based legacy API. The SOAP API returns XMLwith deeply nested namespaced elements. What transformation should the MCP tool apply beforereturning results to Claude?
A. Return the raw XML — Claude can parse XML natively B. Base64-encode the XML and return it as a string C. Convert to a flat key-value pair format D. Convert to a simplified JSON structure that strips namespaces and flattens unnecessary nesting,
keeping only the business-relevant fields
Answer : D
Explanation:
MCP tools should return high-signal, Claude-friendly responses. Complex XML with namespaces and
deep nesting wastes context tokens and confuses tool result processing. Converting to simplified JSON
with only business-relevant fields improves both context efficiency and Claude's ability to use the data.
Option A wastes tokens on XML overhead. Option C may lose hierarchical relationships. Option D
makes the data unusable.
Question # 6
A senior developer is building a chatbot for a hospital that must NEVER provide specific medicaldiagnoses while still being helpful about general health information. A previous attempt using onlysystem prompt instructions failed when a patient described symptoms in detail and Claude provided atentative diagnosis. What is the correct implementation?
A. Add more emphatic language to the system prompt: 'ABSOLUTELY NEVER provide diagnoses' B. Use a two-layer approach: system prompt for general guidance plus a separate classifier model that
screens every response before it reaches the patient, blocking anything containing diagnostic statements C. Implement a PostToolUse classification step that checks every response for diagnostic language and
regenerates if detected D. Limit the conversation length to prevent detailed symptom discussions
Answer : B
Explanation:
Safety-critical content filtering requires defense-in-depth. A classifier model screening every response
provides a deterministic safety layer that the system prompt alone cannot guarantee. The system
prompt provides guidance (often effective), while the classifier provides enforcement (always
effective). This is the same 'prompts for guidance, hooks for enforcement' philosophy. Option A is still
only prompt-level. Option B is less reliable than a dedicated classifier. Option D degrades user
experience.
Question # 7
A developer wants Claude Code to output results in a specific format when run in their CI pipeline.They use headless mode with --json-schema. The schema specifies {issues: [{file: string, line: number,severity: string, message: string}]}. However, the output sometimes includes extra explanation textalongside the JSON. What flag ensures only the JSON schema output is returned?
A. The --json-schema flag already guarantees only schema-compliant JSON output in headless mode B. --quiet to suppress all logging and only show the result C. --json-only to suppress non-JSON output D. Pipe the output through jq to extract only the JSON portion
Answer : A
Explanation:
When using --json-schema in headless mode, Claude Code is designed to output only schemacompliant JSON. The combination of headless mode and --json-schema provides clean machinereadable output suitable for CI pipelines. Option A is not a real flag. Option B may suppress useful
information. Option D is a workaround, not a solution.
Question # 8
An architect implements context awareness (formerly citations) to track which sources Claude uses inits responses. The marketing team wants to display source links alongside generated content. Whatdoes the context awareness feature provide?
A. URLs to original source documents that Claude used during training B. A list of document IDs that were most relevant to the response C. Character-level pointers back to specific locations in the input context, showing exactly which parts
of the provided documents Claude referenced for each claim D. A confidence score indicating how well-supported each claim is by the input documents
Answer : C
Explanation:
Context awareness provides character-level pointers (start and end indices) back to the input context,
showing exactly which parts of the provided documents Claude referenced when generating each
claim. This enables source attribution UI features like highlighting or linking to specific passage
locations. Option A references training data, not input context. Option C lacks granularity. Option D
provides confidence, not attribution.
Question # 9
A developer needs to generate unit tests for a complex function. They have the function implementationand existing tests for similar functions. What prompting strategy produces the highest quality test suite?
A. Send only the function implementation and ask Claude to generate tests B. Send the function, its type definitions, and 2-3 examples of test files for similar functions as
reference — the examples calibrate Claude's testing style, coverage patterns, and assertion conventions C. Ask Claude to list all edge cases first, then generate one test per edge case D. Send the function and a testing framework documentation page
Answer : B
Explanation:
Providing the function, types, and example test files (few-shot reference) calibrates Claude to the
team's testing conventions: assertion style, mocking patterns, edge case coverage, and naming
conventions. This produces tests that match the existing codebase style. Option A lacks calibration.
Option C may produce tests inconsistent with team conventions. Option D provides framework docs
but not team patterns.
Question # 10
A platform engineer is designing an agent that interacts with a third-party API. The API has rate limitsof 100 requests per minute. The agent makes rapid tool calls that can exceed this limit. Where shouldrate limiting be implemented?
A. In the system prompt: 'Wait at least 600ms between API calls' B. In a PreToolUse hook that adds a delay between tool invocations C. In the MCP server implementation, using a token bucket algorithm that queues requests exceeding
the rate limit D. In Claude's API parameters by setting a request_delay field
Answer : C
Explanation:
Rate limiting is best implemented in the MCP server where it's transparent to the agent. A token bucket
algorithm queues excess requests until capacity is available, preventing rate limit errors while allowing
burst handling. Option A relies on prompt compliance and isn't precise. Option C adds delays to all tool
calls, not just rate-limited ones. Option D doesn't exist.
Question # 11
A team builds a legal document analysis agent. The agent needs to cross-reference clauses across a 200-page contract. Their first approach loads the full document and asks Claude to find all cross-references.Results are inconsistent — some cross-references are found, others are missed. What documentprocessing strategy improves reliability?
A. Use a smarter model (Opus instead of Sonnet) for better attention across the full document B. Split the document into overlapping sections, have Claude identify cross-references in each section,
then merge and deduplicate results across sections C. Index the document by clause number first, then query specific clause pairs for cross-references D. Use extended thinking with a large budget to improve attention throughout the document
Answer : D
Explanation:
Extended thinking with a large budget allows Claude to methodically work through the entire
document, tracking cross-references as it goes. For 200-page documents within the context window,
this is more effective than splitting (which may miss cross-section references) or simple full-document
scanning. Option A helps but isn't sufficient alone. Option B may miss references spanning sections.
Option D requires knowing which clauses to check in advance.
Question # 12
A developer is implementing token counting for their application to monitor costs. They need to counttokens before sending requests to avoid exceeding context limits. Which approach does the Anthropicdocumentation recommend?
A. Use the token counting API endpoint to get exact counts before sending the full request B. Use a third-party tokenizer library to estimate token counts locally C. Estimate based on character count: ~4 characters per token for English text D. Send the request and check the usage field in the response for actual token counts
Answer : A
Explanation:
Anthropic provides a token counting API endpoint that returns exact token counts without processing
the full request. This enables pre-flight checks to ensure requests fit within context limits and budget
constraints. Option A may be inaccurate for Claude's specific tokenizer. Option C is a rough estimate.
Option D provides post-hoc information, not pre-flight validation.
Question # 13
An architect wants to implement a 'dry run' mode for their agent where all tool calls are simulatedwithout executing. This is useful for testing agent behavior and estimating costs. Whichimplementation approach is most effective?
A. Add 'this is a dry run, don't actually execute anything' to the system prompt B. Replace all tool implementations with mock versions that return realistic simulated responses C. Use PreToolUse hooks that intercept all tool calls, log them, and return simulated results without
executing the actual tools D. Set effort='low' to minimize the impact of tool calls during testing
Answer : C
Explanation:
PreToolUse hooks provide a clean interception layer for dry-run mode. They can log each tool call (for
analysis and cost estimation), return simulated results (keeping the agent's behavior realistic), and avoid
any side effects from actual execution. This works without modifying tool implementations (Option B)
or relying on prompt compliance (Option A). Option D doesn't prevent execution.
Question # 14
A developer needs to pass sensitive credentials to an MCP server configured in Claude Code. Theywant the credentials stored securely and not committed to the repository. Where should the credentialsbe configured?
A. In .claude/settings.json with the credentials directly in the MCP server configuration B. In environment variables referenced by the MCP server configuration using ${VAR_NAME}
expansion syntax C. In the CLAUDE.md file with instructions for where to find credentials D. Hardcoded in the MCP server source code
Answer : B
Explanation:
MCP server configurations support environment variable expansion using ${VAR_NAME} syntax.
Credentials are stored in environment variables (via .env files, shell profiles, or CI secrets) and
referenced in the configuration. This keeps secrets out of committed files. Option A commits secrets to
the repository. Option C exposes secrets in a documentation file. Option D is a security anti-pattern.
Question # 15
An AI engineer is building a multi-agent system for software testing. Agent A generates test cases,Agent B executes them, and Agent C analyzes results. Agent B discovers a test environmentmisconfiguration that affects all remaining tests. How should Agent B communicate this blocking issueto the orchestrator?
A. Continue executing tests and note failures in the results for Agent C to analyze B. Stop execution and return an error message to the orchestrator C. Return a structured status with escalation metadata: {status: 'blocked', reason:
'environment_misconfiguration', details: '...', blockedTests: [...], suggestedAction:
'fix_environment_and_retry'} D. Call Agent A to regenerate test cases that work with the misconfigured environment
Answer : C
Explanation:
Structured escalation metadata enables the orchestrator to make informed decisions. The status includes
the blocking reason, affected tests, and suggested remediation. This is superior to a generic error
(Option B) because it provides actionable information. Option A wastes resources on known-bad tests.
Option D works around the problem instead of fixing it.
Question # 16
A developer's agent system has a memory of 50 previous customer interactions stored in a database.For each new interaction, they inject all 50 prior interactions into the context for personalization. Thisconsumes 100K tokens, leaving limited room for the current conversation. What is the better approach?
A. Summarize all 50 interactions into a 5K token customer profile that's injected instead B. Retrieve only the 3-5 most relevant prior interactions (using embedding similarity or recency) and
inject those, keeping context lean while maintaining personalization C. Increase to a 1M token context model to fit all history D. Store all interactions in a tool that Claude can query on demand
Answer : A
Explanation:
Summarizing interaction history into a concise customer profile preserves the key insights (preferences,
recurring issues, communication style) while consuming far fewer tokens. This is more efficient than
raw injection (full history) and more complete than selecting only a few interactions (which may miss
important patterns). Option A is expensive. Option B may miss important context. Option D adds round
trips.
Question # 17
A technical lead is implementing a content moderation system using Claude. They need to classifyuser-generated content as safe, questionable, or unsafe. For legal compliance, they need an audit trailshowing why each decision was made. What API features support this requirement?
A. Enable extended thinking to capture the reasoning, and use structured output for the classification —
the thinking blocks provide the audit trail while the structured output provides the consistent decision
format B. Use the Messages API with logging enabled to capture all request/response pairs C. Use a separate API call for classification and another for explanation generation D. Store the raw API response JSON as the audit trail
Answer : A
Explanation:
Extended thinking provides transparent reasoning (the 'why' behind the decision) while structured
output ensures consistent classification format. Together, they create a complete audit trail: the thinking
blocks show deliberation, and the structured output shows the deterministic output. Option A lacks
decision reasoning. Option C doubles API costs. Option D contains the decision but not the reasoning.
Question # 18
A team uses Claude Code's /init command to generate the initial CLAUDE.md for their project. Aftergeneration, they want to customize it. The /init command has already analyzed the repository. What isthe recommended approach for customization?
A. Delete the generated CLAUDE.md and write one from scratch B. Keep the generated CLAUDE.md as a base and iteratively refine it — add project-specific
conventions, remove irrelevant sections, and commit the customized version C. Generate multiple CLAUDE.md files with /init and merge the best parts D. Never modify the /init output — it's optimized for the repository
Answer : B
Explanation:
The /init command creates a good starting point based on repository analysis. The recommended
workflow is to keep this base and iteratively customize it: add project-specific coding conventions,
team preferences, and workflow rules. Remove auto-detected rules that don't apply. Commit the
customized version. Option A loses the auto-detected insights. Option C is redundant. Option D misses
the opportunity for customization.
Question # 19
A developer implements an MCP tool for image processing. The tool accepts an image URL andreturns analysis results. During testing, they find that Claude sometimes passes a data URL (base64-encoded image) instead of an HTTP URL. The tool only supports HTTP URLs. How should the toolhandle this gracefully?
A. Return an error: 'Invalid URL format' without further guidance B. Accept data URLs by decoding the base64 content within the tool implementation C. Return a structured error with the constraint: {isError: true, message: 'Only HTTP/HTTPS URLs are
supported. Data URLs (base64) cannot be processed. Please provide the image's HTTP URL.',
isRetryable: true} D. Silently ignore the data URL and return empty results
Answer : C
Explanation:
Structured error responses with clear constraints help Claude self-correct. By returning the specific
requirement (HTTP/HTTPS only), the reason (data URLs can't be processed), and marking it as
retryable, Claude can adjust and provide a valid URL. Option A is too vague. Option B adds
unnecessary complexity if there's a reason only HTTP is supported. Option D hides the failure.
Question # 20
An architect builds an agent that must handle both simple lookups (e.g., 'What is the status of order#1234?') and complex investigations (e.g., 'Why was order #1234 delayed and what is the impact on thecustomer's account?'). Currently both types use the same processing pipeline with extended thinking,making simple lookups slow. What architecture balances speed and depth?
A. Disable extended thinking for all requests and rely on tool results for complex analysis B. Let users select 'quick' or 'detailed' mode for their queries C. Add a timeout that kills thinking after 3 seconds for simple queries D. Use a classifier to route simple lookups (effort='low', no thinking) to a fast path and complex
investigations (effort='high', thinking enabled) to a deep-analysis path
Answer : D
Explanation:
A routing classifier separates queries by complexity, sending simple lookups through an optimized fast
path (low effort, no thinking) and complex investigations through a thorough deep-analysis path (high
effort, thinking enabled). This optimizes both latency for simple queries and quality for complex ones.
Option A loses depth. Option C may produce inconsistent results. Option D adds friction.
Question # 21
An architect needs Claude to generate a complex financial model with nested calculations. They wantto verify that intermediate calculations are correct before using the final result. Extended thinkingwould show the reasoning, but they need the intermediate values in a structured format. What approachcombines both?
A. Enable thinking and ask Claude to include intermediate values in the thinking blocks B. Use a structured output schema with nested objects that mirror the calculation hierarchy: {inputs:
{...}, intermediate: {step1: {...}, step2: {...}}, final: {...}} with thinking enabled for reasoning visibility C. Make separate API calls for each calculation step D. Use tool calls for each intermediate calculation, collecting results along the way
Answer : B
Explanation:
Combining structured output (which captures intermediate values in a verifiable schema) with extended
thinking (which provides reasoning transparency) gives both structured data and reasoning visibility.
The schema mirrors the calculation hierarchy, making each step verifiable. Option A puts values in
thinking which isn't reliably parseable. Option C loses context between steps. Option D adds
unnecessary complexity.
Question # 22
A developer is configuring Claude Code settings and notices there are three levels of settingsfiles: .claude/settings.json (project), .claude/settings.local.json (local), and ~/.claude/settings.json(user). They add an MCP server to the project settings. A teammate adds the same server with differentconfiguration to their local settings. Which takes precedence?
A. Project settings (.claude/settings.json) always take precedence B. Local settings (.claude/settings.local.json) take precedence over project settings for the same
configuration C. User settings (~/.claude/settings.json) have the highest precedence D. The settings are merged with conflicts causing an error
Answer : B
Explanation:
Local settings (.claude/settings.local.json) override project settings (.claude/settings.json) for the same
configuration keys. This allows individual developers to customize their local environment without
affecting the shared project configuration. User settings provide defaults that both project and local can
override. Option A understates local settings. Option C has the precedence reversed. Option D doesn't
match the merge behavior.
Question # 23
A solutions engineer is building a RAG (Retrieval Augmented Generation) system that retrievesdocuments and uses Claude to answer questions. After retrieval, they inject 5 relevant document chunkstotaling 15K tokens into the prompt. They want to maximize cache hits across users who ask similarquestions. What prompt structure optimizes caching?
A. System prompt ? document chunks ? user question (documents change per query, breaking the
cache) B. System prompt ? user question ? document chunks C. Put all content in a single user message to simplify caching D. System prompt (cached) ? common document corpus (cached) ? query-specific chunks ? user
question
Answer : D
Explanation:
Cache matching works on prefixes. Structuring as system prompt ? common corpus ? query-specific
content ? user question maximizes the cacheable prefix. The system prompt is shared across all
requests. A common document corpus (frequently accessed documents) extends the shared prefix.
Query-specific chunks come after. Option A breaks the cache frequently. Option B loses document
caching. Option D doesn't leverage prefix caching.
Question # 24
A team has their Agent SDK agent configured with max_turns: 10. Their complex workflow typicallyrequires 15-20 tool calls but the agent stops after 10 turns. They need the agent to complete the fullworkflow. What are the two options for handling this?
A. Increase max_turns to 25 and hope it's enough B. Split the workflow into exactly 10 steps or fewer C. Either increase max_turns, or implement multi-turn looping where the orchestrator checks if the task
is complete after max_turns and re-invokes the agent with the current state D. Remove the max_turns limit entirely to let the agent run indefinitely
Answer : C
Explanation:
The two approaches are: (1) increase max_turns to accommodate the workflow, or (2) implement outerloop orchestration that checks task completion after each max_turns cycle and re-invokes the agent
with accumulated state. The second approach provides better control and prevents runaway agents.
Option A is fragile. Option C may not be possible. Option D risks unbounded execution.
Question # 25
Your team is designing a prompt template for a customer email generator. They want Claude tomaintain the customer's language (English, Spanish, French) automatically without explicit languageinstructions. What is the most effective approach?
A. Detect the customer's language first with a classification call, then include a language instruction B. Include a few-shot example in each language to prime Claude for multilingual responses C. Use a separate translation API to convert all inputs to English and outputs back to the original
language D. Place the customer's original message prominently in the prompt — Claude naturally mirrors the
input language when generating responses
Answer : D
Explanation:
Claude naturally mirrors the language of the input it's responding to. By placing the customer's original
message prominently in the prompt, Claude generates the response in the same language without
explicit instructions. This is simpler and more reliable than classification (Option A), few-shot per
language (Option B), or external translation (Option D). The exam guide emphasizes leveraging
Claude's natural language matching behavior.
