CCA-F Practice Questions With Explanations: 20 Free Scenarios [2026]

An insurance company runs a claims-intake system as a hub-and-spoke (a coordinator agent that routes work to specialized subagents). The coordinator collects the policy number and incident details from the customer, then delegates to a fraud-screening subagent. In testing, the subagent repeatedly reports "no policy number provided" even though the coordinator confirmed it two turns earlier. What is the likely cause and the correct fix?

A compliance team's agent produces a weekly regulatory digest. A coordinator delegates three research jobs (EU, US, and UK rule changes) to subagents, then a fourth subagent writes the digest from all three sets of findings. The current design runs the four subagents strictly one after another and takes forty minutes. Which TWO changes are correct? (Select TWO)

An IT helpdesk agent resets passwords, unlocks accounts, and assigns software licenses. The operations lead wants a policy for when the agent hands a ticket to a human. Tickets sometimes stall when the agent retries the same unlock call with the same arguments and nothing changes. Which escalation trigger should be implemented programmatically?

A support operation runs one Claude Code investigation session per fraud case. Day-shift analysts stop mid-investigation, and the night shift must continue from the exact point where they left off, with the full history of tool calls and findings intact. Separately, a senior analyst wants to test an alternative theory on one case without disturbing the main line of investigation. Which pairing is correct?

A logistics company's agent re-plans routes when a truck breaks down. The agentic loop (send a message, run any tool Claude requests, send the result back, repeat) calls a routing tool, a driver-notification tool, and a fleet database. In production it sometimes stops before drivers are notified, and sometimes keeps calling the routing tool after a plan is final. How should the loop decide when to continue and when to stop?

An HR team's pipeline sends every incoming resume to Claude with three tools defined: extract_candidate, check_duplicate, and notify_recruiter. Every resume must produce a structured candidate record on the first call, yet about one response in twenty comes back as a prose summary instead of an extract_candidate call. Which change fixes this most reliably?

A platform team is standardizing Claude Code for twelve engineers. Everyone needs the same Jira MCP server (an external tool server speaking the Model Context Protocol), which authenticates with a token that must never be committed. Several engineers also run personal MCP servers (note-taking, music) that teammates should not inherit. Which TWO configuration decisions are correct? (Select TWO)

A retail support agent has two tools: lookup_customer, described as "Gets customer info", and find_customer, described as "Finds customer data". The first takes an exact customer ID; the second does a fuzzy search on name and email. The agent frequently calls the ID tool with a name and gets a not-found error. What should you change first?

You are writing an MCP tool that charges a card through a payments gateway. The gateway returns HTTP 429 when the merchant is rate-limited and HTTP 403 when the API key lacks the charge permission. Today the tool returns an empty result in both cases, and the agent tells customers the payment "did not go through". How should the tool respond instead?

A platform lead wrote the repository's testing conventions (which runner to use, how to name fixtures) into ~/.claude/CLAUDE.md on their laptop. CLAUDE.md is the instructions file Claude Code loads at start; teammates' sessions ignore the conventions. The lead also keeps a personal preference for terse responses that should never affect anyone else. Which TWO placements are correct? (Select TWO)

A fintech team has two hard requirements for Claude Code in its payments repository: the agent must never edit files under migrations/, and the black formatter must run after every edit to a Python file. A CLAUDE.md line for each already exists, and both requirements are still violated in long sessions. Which mechanism enforces them?

A CI pipeline invokes Claude Code on every pull request to produce a list of review findings that a later job turns into GitHub comments. Some runs hang until the job times out, and on runs that do finish, the parsing step fails on the output. Which invocation fixes both problems?

A security team wants a /dependency-audit skill (a reusable, on-demand instruction set for Claude Code) that scans lockfiles, runs an audit command, and produces a long report. Two constraints: the report's volume must not fill the main conversation, and the skill must never be able to modify files. Which frontmatter satisfies both?

A procurement platform extracts purchase-order fields with Claude. Two defects recur: about 2% of responses are not parseable JSON, and in another few percent the line-item amounts do not add up to the stated total. The current prompt says "return valid JSON with these fields" and includes six examples. What is the right design?

A publisher has two workloads: re-tagging 400,000 archived articles, due within two days, and a writer's assistant that suggests tags in a multi-turn chat while an article is being drafted. Finance wants the Batch API's 50% saving applied wherever it is safe. Which TWO decisions are correct? (Select TWO)

A community platform uses Claude to flag posts for moderator review. The prompt says "be careful not to over-flag harmless posts", yet moderators report that most flagged items are benign, and the queue has become unmanageable. Which revision most directly reduces the false positives?

A real-estate extraction schema has a parking_type enum with garage, street, and none. Listings that say only "parking available" get labeled garage, and downstream valuations are skewed. Some listings say nothing about parking at all, and those must stay distinguishable from the ambiguous ones. How should the schema change?
