Question 300

An incident-analysis agent is allowed to inspect logs with Bash but must never erase them. A prompt injection inside a retrieved file asks it to run `rm -rf logs/`. Where should the decisive safeguard operate?

  1. A final-answer review that redacts the deletion command after execution.
  2. An instruction embedded in the same untrusted file telling the agent to be careful.
  3. A nightly backup without any execution-time command checks.
  4. A trusted pre-tool command policy that rejects destructive Bash operations before they execute.

Explanation

Correct Answer

D:

Preventive interception can block the side effect regardless of model instructions or injected text. Scope the rule to permitted commands and working directories.

Incorrect Answers

A:

Final output inspection cannot recreate logs deleted by an earlier tool call.

B:

Untrusted document contents cannot reliably enforce tool permission boundaries.

C:

Backups aid recovery but do not prevent unauthorized destruction or loss of current evidence.

Question 301

An analyst resumes an overnight research session after its OAuth access token expired. The saved conversation still contains useful citations and query decisions. What should session recovery do?

  1. Restore the verified analysis state, obtain a fresh authorized token, and retry only operations that have not completed.
  2. Reuse the expired token until an API accepts it.
  3. Discard all cited findings whenever the access token expires.
  4. Ask the model to invent API responses for the expired session.

Explanation

Correct Answer

A:

Persistent context and credential validity have different lifecycles. Reauthentication permits continuation without replaying completed research.

Incorrect Answers

B:

A known expired credential is not a reliable or authorized basis for recovery.

C:

Loss of an authentication token does not invalidate previously confirmed research evidence.

D:

Fabricated tool results conceal authentication failures and compromise source provenance.

Question 302

Two developers share a repository. One has a personal preference for verbose commentary, while the repository requires a strict code-test workflow. Which memory placement is appropriate?

  1. Put mandatory shared test requirements in repository CLAUDE.md and keep personal style preferences in individual user-level configuration.
  2. Put mandatory CI rules exclusively in one developer’s private global memory.
  3. Copy individual personal preferences into every generated source file.
  4. Treat every personal preference as a reason to disable the repository test workflow.

Explanation

Correct Answer

A:

Shared instructions should govern consistent work across contributors; individual preferences should not silently impose project policy on everyone.

Incorrect Answers

B:

Other contributors would not reliably receive a project-wide requirement.

C:

This pollutes code artifacts and does not establish a maintainable instruction hierarchy.

D:

Optional style choices cannot override required project verification.

Question 303

A CI pipeline automatically invokes Claude Code on pull requests from untrusted forks. The review task needs source diffs but not deployment credentials. Which runtime boundary matters most?

  1. Inject production tokens so the reviewer can test every deployment pathway.
  2. Grant every pull request job organization-wide administrator rights for reproducibility.
  3. Suppress security logging so contributors cannot inspect the reviewer environment.
  4. Run the review with read-only repository access and without privileged secrets or write tokens exposed to fork-supplied code.

Explanation

Correct Answer

D:

Untrusted contributions must not inherit deployment credentials. A constrained review can inspect changes without granting release authority.

Incorrect Answers

A:

A fork may execute attacker-controlled code. Exposing privileged tokens creates a direct compromise path.

B:

Overbroad permissions are unnecessary for static review and multiply potential damage.

C:

Removing audit records does not replace credential isolation and reduces incident visibility.

Question 304

A loan-support assistant reports 98% confidence that two similar customer names refer to the same person, but their account identifiers disagree. It is asked to merge the records. What is the responsible response?

  1. Merge immediately because the probability is above 95%.
  2. Delete the inconsistent identifier field to improve consistency.
  3. Copy all source fields to both accounts and declare them the same person.
  4. Withhold the merge and seek authoritative identifier resolution, rather than treating the confidence score as identity proof.

Explanation

Correct Answer

D:

A highly confident wrong match could corrupt financial records. Material contradictions take precedence over model self-rating.

Incorrect Answers

A:

Confidence alone is not an independent verification of identity, especially when identifiers conflict.

B:

Removing contrary evidence hides the actual ambiguity and undermines accountability.

C:

Duplicating sensitive fields does not resolve an uncertain match and may spread private data.

Question 305

A concierge agent issues simultaneous inventory requests for three warehouses. Responses arrive out of order. How can the host avoid attaching quantities to the wrong warehouse?

  1. Assume the first response always belongs to the first warehouse.
  2. Assign all three responses to the warehouse with the most stock.
  3. Discard the entire conversation whenever results arrive in a different order.
  4. Join tool results to their originating calls using stable tool-use identifiers and warehouse keys before continuing the reasoning loop.

Explanation

Correct Answer

D:

Correlation identities preserve causality when latency differs. Display order cannot determine which request a response belongs to.

Incorrect Answers

A:

Concurrent requests can finish in any order. Positional matching risks false stock information.

B:

A quantity-based heuristic is unrelated to the source request and would corrupt records.

C:

Ordering variation is normal. Stable identifiers allow safe reconciliation without lost context.

Question 306

A fraud-review coordinator has a worker that reads restricted account data and a different worker that drafts an executive summary. The summary needs aggregate patterns only. What should the coordinator pass?

  1. Publicly disclose all cases before running the synthesis.
  2. A sanitized, minimum-necessary finding summary with evidence references and explicit limitations, not raw protected account data.
  3. The full raw account database because the summary agent is part of the same workflow.
  4. Only a verdict with no evidence or uncertainty indicators.

Explanation

Correct Answer

B:

Task-specific context limits exposure while keeping synthesis grounded in verified findings.

Incorrect Answers

A:

Disclosure is a separate consequential action and not required for drafting an internal report.

C:

Same workflow membership does not grant unrestricted access to private records.

D:

A bare conclusion is difficult to evaluate and can obscure weak analysis.

Question 307

A warehouse-ordering agent submits a purchase request, times out waiting for a response, and is unsure whether the supplier accepted it. What should the orchestration do?

  1. Resubmit with a new random order number immediately.
  2. Assume the order completed and notify customers without any supplier evidence.
  3. Cancel all unrelated customer orders to free processing capacity.
  4. Query the outcome using the original idempotency key before retrying the same request.

Explanation

Correct Answer

D:

A timeout does not imply nonexecution. Reconciliation with stable identity prevents duplicate purchases.

Incorrect Answers

A:

A different identity can create a second independent order after the first succeeded.

B:

The missing response cannot establish a successful transaction.

C:

Unrelated side effects do not resolve uncertainty about the specific purchase.

Question 308

A team is replacing an authentication library used by multiple services. Its exact call sites are not yet mapped. Which sequence is most defensible?

  1. Deploy the new library everywhere before inspecting the callers.
  2. Test only the new library's documented API examples and assume all deployed callers use those supported interfaces.
  3. Replace all authorization checks with permissive defaults to simplify migration.
  4. Discover dependent call sites, design compatibility changes, test representative paths, then deploy in controlled phases.

Explanation

Correct Answer

D:

Dependencies must be identified before edits. A staged graph prevents hidden clients from breaking during rollout.

Incorrect Answers

A:

Premature deployment risks unsupported signatures and authentication outages.

B:

Passing examples establishes that an API works in isolation, not that every deployed service calls it compatibly. Inventory actual call sites and authentication dependencies before phasing the migration.

C:

Disabling security changes application behavior and violates the purpose of the migration.

Question 309

A coordinator runs three parallel reviews of the same repository at different commits. A late result from the oldest commit arrives after the main branch was updated. How should it be handled?

  1. Overwrite newer verified findings with the older worker report.
  2. Validate the returned commit identifier and assigned task before merging findings into the current assessment.
  3. Take the latest-arriving result as proof it examined the latest code.
  4. Remove commit metadata to reduce context length.

Explanation

Correct Answer

B:

Source version binding prevents stale conclusions from being treated as results for a newer code state.

Incorrect Answers

A:

Blind replacement can reintroduce resolved vulnerabilities and false statuses.

C:

Arrival time and source version are unrelated in parallel work.

D:

Deleting provenance destroys the basis for deciding whether the review is still applicable.

Question 310

An agent toolkit exposes `archive_accounts` and `inspect_accounts`. The first actually disables customer accounts; its description says only “organize records.” What is the proper tool-design change?

  1. Make both operations silently disable accounts for consistent behavior.
  2. Remove the authorization guard so all calls complete faster.
  3. Rename and document the destructive operation with its exact effects, prerequisites, and reversibility, separate from inspection.
  4. Keep the vague description and hope the model guesses from the name.

Explanation

Correct Answer

C:

Explicit semantics help the host and model select the intended action and gate account disabling appropriately.

Incorrect Answers

A:

A read-only inspection must not acquire unannounced destructive side effects.

B:

Tool descriptions complement rather than replace runtime permission checks.

D:

Ambiguous effects increase the risk of accidental disablement.
