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.

Question 311

An MCP service rejects a search request with HTTP 429 and a Retry-After hint. An agent currently treats it as a permanent “not found.” What response contract is correct?

  1. Report a user-permission denial whenever the server is busy.
  2. Report a rate-limited, retryable error with the backoff hint and no claim that the resource is absent.
  3. Return an empty successful list and mark the search complete.
  4. Retry rapidly with no delay until the server accepts the request.

Explanation

Correct Answer

B:

A capacity limit is distinct from lookup failure. Structured retry hints support safe bounded recovery.

Incorrect Answers

A:

Rate limiting does not establish an authorization failure.

C:

No data was retrieved, so an empty result would misrepresent evidence.

D:

Ignoring backoff can worsen rate limiting and cause unnecessary cost.

Question 312

A research worker should assess shipping options. The integration also offers `create_shipment`, which commits a charge. What should be available to this worker?

  1. All shipment tools, relying only on a natural-language reminder.
  2. Expose `create_shipment` to the rate-comparison worker for a staging connectivity check, with no separate charge approval.
  3. Only the charged tool and no read capability.
  4. Read-only carrier-rate and tracking tools, with shipment creation reserved for a separately authorized execution worker.

Explanation

Correct Answer

D:

Separating discovery from charged actions is a least-privilege boundary.

Incorrect Answers

A:

Prompt instructions can be bypassed or misunderstood; capability restriction is stronger.

B:

Even a staging or test shipment can create a real order or fee depending on provider behavior. The worker only needs read-only rates and tracking; shipment creation requires independent authorization.

C:

It would force consequential actions to answer a read-only research question.

Question 313

A developer adds an MCP endpoint from a community README. It advertises the same tool name as a trusted internal server but a different URL. What should happen first?

  1. Send internal API tokens to the new endpoint to see if it responds.
  2. Disable logs and automatically trust all tools listed in the README.
  3. Verify endpoint identity, permission scope and source trust before enabling the new server or resolving naming conflicts.
  4. Treat matching tool names as proof both servers are interchangeable.

Explanation

Correct Answer

C:

An identical tool name does not establish common ownership. Trust must attach to authenticated endpoints.

Incorrect Answers

A:

Credential exposure is not a safe identity-verification method.

B:

Unaudited automatic trust broadens the attack surface.

D:

Untrusted endpoints can mimic names to gain access to prompts or data.

Question 314

A developer knows the exact line in a configuration file that contains a wrong timeout. The file includes hand-maintained comments. Which built-in operation best preserves unrelated content?

  1. Inspect the surrounding lines and apply a targeted Edit to the timeout value.
  2. Overwrite the entire file with a minimal example containing only the timeout.
  3. Use Glob to modify the timeout automatically.
  4. Use Grep as a write operation against every configuration file.

Explanation

Correct Answer

A:

A scoped edit retains comments and unrelated settings. Testing afterward checks for unintended effects.

Incorrect Answers

B:

Whole-file replacement could erase important comments and settings.

C:

Glob discovers path matches; it does not perform a scoped content change.

D:

Grep is a search tool, not a surgical patch facility.

Question 315

A reusable skill contains deployment guidance used during planning. A developer wants a separate command to run the deployment only after approval. How should they organize it?

  1. Use the skill for reference and a distinct explicitly invoked workflow that checks approval before executing deployment.
  2. Automatically deploy whenever the skill documentation is read.
  3. Hide the deployment shell step within examples of an explanatory skill.
  4. Make every project command irreversibly modify production systems.

Explanation

Correct Answer

A:

Reusable knowledge should not cause unrequested actions. Explicit invocation keeps the release boundary visible.

Incorrect Answers

B:

Reading procedural advice is not authorization to act.

C:

Hidden side effects can surprise users and create unsafe changes.

D:

Commands should match their declared scope and permissions.

Question 316

A mixed repository has Terraform modules and front-end CSS. A rule requires infrastructure changes to include policy-as-code verification, but the assistant runs those checks on every CSS edit. What is the improvement?

  1. Scope the infrastructure verification rule to Terraform-related paths, keeping shared security requirements separately documented.
  2. Disable policy-as-code verification on all infrastructure changes.
  3. Copy all Terraform rules into front-end source comments.
  4. Require a full infrastructure redeploy after every change to any file.

Explanation

Correct Answer

A:

Path-specific rules focus validation where it applies without omitting global safety requirements.

Incorrect Answers

B:

The problem is improper scope, not the necessity of infrastructure validation.

C:

Adding irrelevant instructions to CSS does not clarify ownership.

D:

This adds needless operational risk and unrelated work.

Question 317

A developer requests correction of a misspelled configuration flag in a README. No code or production state will change. What is a proportionate workflow?

  1. Rewrite all product code because its flag appears in documentation.
  2. Skip checking the actual README and announce the correction completed.
  3. Inspect the affected paragraph, make a scoped documentation edit, then verify the rendered text and diff.
  4. Prepare a multi-week deployment strategy before touching the typo.

Explanation

Correct Answer

C:

A small reversible edit does not need a major migration plan, but still benefits from verification.

Incorrect Answers

A:

A documentation typo does not establish a source-code defect.

B:

A claim of completion needs a real edit and verification.

D:

Heavy planning is disproportionate to a localized documentation correction.

Question 318

An assistant optimizes a search function but a benchmark shows p95 latency rose from 150 ms to 500 ms. It reports success because the new code is shorter. What next?

  1. Treat the benchmark as a failed performance criterion, inspect the changed path and iterate against the measured regression.
  2. Ignore the benchmark because the code contains fewer lines.
  3. Claim the change improved p95 because the median was not measured.
  4. Remove all benchmark tests before merging.

Explanation

Correct Answer

A:

Shorter source is not proof of faster behavior. Evaluation should target the specified latency requirement.

Incorrect Answers

B:

Code length is not the user’s performance acceptance criterion.

C:

Missing or different metrics cannot override a measured p95 regression.

D:

Suppressing a failing measurement hides rather than corrects the defect.

Question 319

A classifier labels every health-related chatbot response as regulated medical advice, including appointment reminders. What decision criteria should it be given?

  1. Require an actual patient-specific diagnostic or treatment recommendation, permit a non-advice category, and cite the relevant text.
  2. Flag any response containing the word appointment.
  3. Remove the administrative category so every message must be risky.
  4. Ask the model to increase confidence when it lacks supporting text.

Explanation

Correct Answer

A:

Specific criteria and evidence reduce false positives for administrative messages.

Incorrect Answers

B:

A keyword is not evidence that treatment guidance was provided.

C:

Forcing a binary high-risk classification creates avoidable errors.

D:

Unsupported confidence does not improve factual correctness.

Question 320

A contract extractor confuses “shall not retain records” with “shall retain records.” Which few-shot addition is most helpful?

  1. More examples of unrelated invoices containing only positive statements.
  2. A rule to ignore the word not in every document.
  3. A prompt asking for the most optimistic interpretation.
  4. Paired examples differing only by negation, each labeled with the correct obligation and exact text span.

Explanation

Correct Answer

D:

Minimal contrasts teach the model to attend to legally decisive words rather than nearby subject terms.

Incorrect Answers

A:

Unrelated examples do not address the negation failure mode.

B:

Negation reverses the obligation. Ignoring it causes systematic errors.

C:

Optimism cannot determine a contract’s actual requirement.
