Anthropic CCA-F Practice Test 49

Question 480

A coding agent reviews build scripts for security concerns. The project provides shell execution and production deployment tools, but the user requested a read-only assessment. What tool set should the coordinator grant?

  1. Give the reviewer an unrestricted shell to install dependencies and run repository scripts during evidence collection.
  2. Automatic script execution from every retrieved file.
  3. Source reading/search tools and any separately safe testing capability, with deploy and destructive actions withheld.
  4. All tools because the agent has coding expertise.

Explanation

Correct Answer

C:

Least privilege matches the review scope while still supporting evidence gathering.

Incorrect Answers

A:

Running source-controlled scripts under an unrestricted shell can perform side effects and exceed the requested read-only analysis. Prefer narrowly scoped file-reading tools; any test execution needs its own authorization boundary.

B:

Untrusted code should not be run merely to read it.

D:

Expertise does not create authorization for side effects.

Question 481

A project connects an internal audit MCP server and a public demo server. Both advertise a tool named `search_records`. The assistant is requested to search internal compliance data. What should routing verify?

  1. Have the model guess which one is internal from response wording.
  2. Choose the explicitly authorized internal server identity and tool, not the name alone.
  3. Use whichever `search_records` appears first in the registry.
  4. Send internal records to both servers and compare results.

Explanation

Correct Answer

B:

Tool names can collide across servers. Provenance and permission must bind the selected endpoint.

Incorrect Answers

A:

Post hoc text cannot substitute for verified server identity.

C:

Registry ordering does not establish trust or data scope.

D:

Broad dispatch could disclose confidential data to an untrusted endpoint.

Question 482

A sanitizer removes sensitive data from tool errors, but also strips the `permission_denied` status. The agent then interprets the empty response as a successful lookup. What should be corrected?

  1. Retry the denied read under a different user identity automatically.
  2. Preserve nonsecret error classification and correlation metadata while redacting only protected values.
  3. Remove the entire error and return an empty success.
  4. Expose the original secret-bearing error to every worker.

Explanation

Correct Answer

B:

Sanitization should minimize exposure without destroying control-flow evidence.

Incorrect Answers

A:

A permission failure is not authorization to probe alternative credentials.

C:

That converts a known failed operation into a false completion signal.

D:

Broad exposure is unnecessary; safe structured fields can remain.

Question 483

A travel assistant requests flights and a hotel. The flight tool returns promptly; the hotel tool is still running. Its final answer claims both are confirmed. Which loop rule was violated?

  1. Required result reconciliation: completion needs confirmed outcomes for both requested services or an explicit partial status.
  2. An agent must always call every tool sequentially even when they are independent.
  3. A model cannot produce text while a tool call is pending.
  4. The flight tool should be rerun until the hotel result arrives.

Explanation

Correct Answer

A:

A finished flight lookup does not prove hotel availability or booking.

Incorrect Answers

B:

Parallelism is not the problem; missing result verification is.

C:

Text may be streamed, but it must not misstate unverified outcomes.

D:

Unrelated retries do not settle the outstanding hotel action.

Question 484

Five agents repeat an outdated price from a blog, while one agent retrieves an authenticated current product price. What should the coordinator prioritize?

  1. The current authoritative price and its applicability, recording why the other results are stale.
  2. The blog price because more agents reported it.
  3. The average of all six prices.
  4. The lowest price as a customer-friendly guess.

Explanation

Correct Answer

A:

Consensus among correlated secondary reports does not outweigh direct current evidence.

Incorrect Answers

B:

Worker count is not source authority.

C:

Combining stale and current figures invents a transaction price.

D:

A favorable estimate is not the current listed cost.

Question 485

A model explains why deleting an account seems beneficial, then calls `delete_account` without current permission. The application had provided general safety instructions. What design closes the gap?

  1. Ask the model to output a confidence score above 90%.
  2. Let the deletion happen and email a supervisor afterward.
  3. A pre-execution permission check tied to the authenticated actor, exact account and requested deletion.
  4. An even longer reminder that deletion is serious.

Explanation

Correct Answer

C:

Deterministic enforcement prevents model reasoning from conferring its own authority.

Incorrect Answers

A:

Confidence does not grant the right to delete another account.

B:

Notification cannot prevent an unauthorized irreversible effect.

D:

Additional prose remains a probabilistic guidance layer.

Question 486

An archive contains 2,000 independent documents. Each must be classified and then a single distribution summary created. Which decomposition best fits?

  1. Aggregate only the first worker’s results regardless of coverage.
  2. Drop file IDs to shorten each classification response.
  3. Classify disjoint document sets in parallel with stable IDs, then aggregate validated per-file outcomes.
  4. Give each worker the entire archive, then use a majority vote on their independently generated summaries.

Explanation

Correct Answer

C:

Independent tasks can fan out, while a final reduction verifies coverage and totals.

Incorrect Answers

A:

An incomplete shard cannot represent the whole archive.

B:

Identity is required to reconcile missing and duplicate records.

D:

Redundant full-corpus work is costly and may still miss duplicate or omitted file IDs. Disjoint per-file assignments with stable identifiers allow deterministic coverage reconciliation before one summary.

Question 487

A slow review job for commit A finishes after a faster job for commit B and overwrites the current pull-request status. What control avoids this?

  1. Bind each review result to its source commit and update current status only when the result still applies.
  2. Choose the latest-arriving job as the current result.
  3. Combine both results without labeling which commit they tested.
  4. Disable all source hashes to reduce CI metadata.

Explanation

Correct Answer

A:

Source-version checks prevent stale jobs from superseding newer evidence.

Incorrect Answers

B:

Completion order is unrelated to commit freshness.

C:

Unlabeled findings may refer to obsolete code.

D:

Content identity is essential to prevent stale approvals.

Question 488

A certification guide illustrates a feature available on an older model. Current product docs state that support depends on the selected model. Which teaching claim is most accurate?

  1. Say every model necessarily supports the old example.
  2. Remove the guide concept because one model lacks the feature.
  3. Hide the version distinction and cite the guide as current API proof.
  4. Explain the guide’s scenario and separately qualify current product availability by supported model.

Explanation

Correct Answer

D:

An exam concept and a current feature matrix can both be true within their respective scope.

Incorrect Answers

A:

Compatibility cannot be inferred across all releases.

B:

The published technical requirement can still test the underlying design decision.

C:

That conflates historical exam framing with live implementation.

Question 489

A developer is asked to make report generation read-only. The exact write location is unknown, but it calls `writeFile`. Which first tool sequence is appropriate?

  1. Overwrite the first file found under reports.
  2. Read only the README and mark the file writes removed.
  3. Search source references to `writeFile` and the report function, then read relevant call sites before edits.
  4. Run a broad search-and-replace removing all writeFile calls before inspecting which function owns report generation.

Explanation

Correct Answer

C:

Evidence-based code search identifies real side effects and their dependencies.

Incorrect Answers

A:

Path proximity alone does not prove where the write occurs.

B:

Documentation inspection is not a source change.

D:

A blind global replacement could disable unrelated logging, exports, and state storage. Search and read the actual report-writing call sites before applying a minimal permission-safe change.

Question 490

A reusable `/incident-summary` skill sometimes omits unresolved facts, making a preliminary report sound final. What improvement matters most?

  1. Hide all source identifiers to keep summaries shorter.
  2. Auto-close incidents when the skill generates a report.
  3. Define required evidence, confirmed findings, open questions and next-action fields in its output contract.
  4. Tell the model to sound definitive regardless of evidence.

Explanation

Correct Answer

C:

Explicit fields make uncertainty a first-class result rather than prose that can be silently omitted.

Incorrect Answers

A:

Provenance helps reviewers verify consequential statements.

B:

Report drafting is not authorization for operational closure.

D:

Certainty without support worsens incident reporting.
