Question 250

A service rotates signing keys and a partner verifies signed callbacks using the old public key. The team has not agreed on transition overlap. What mode is appropriate?

  1. Plan key publication, overlap, cutover tests and rollback before changing keys, then execute the agreed stages.
  2. Destroy the old key immediately because rotation is a security improvement.
  3. Post private signing keys in a shared document to coordinate the partner.
  4. Assume all partner clients refresh keys instantly without evidence.

Explanation

Correct Answer

A:

A signing-key rotation has external dependencies and can break verification. A phased plan protects service continuity.

Incorrect Answers

B:

Abrupt removal may invalidate outstanding signatures and partner callbacks. The transition must be designed.

C:

Partners typically need trust material such as public keys, not secret private keys. Publishing private material is unsafe.

D:

Clients may cache keys or require scheduled updates. Compatibility must be verified.

Question 251

A generated ID parser handles ASCII customer names but rejects valid accented letters. An engineer suggests simply disabling all validation. What is the better improvement?

  1. Declare every non-ASCII customer name fraudulent.
  2. Add representative Unicode fixtures, update the precise character handling, and run both security and acceptance tests.
  3. Remove all length and syntax checks to accept every byte string.
  4. Convert accented names to empty strings to keep ASCII-only output.

Explanation

Correct Answer

B:

Targeted tests capture the legitimate edge case while preserving constraints against malformed input. Broad validation removal is unnecessary.

Incorrect Answers

A:

Language and script are not fraud signals. The parser should handle legitimate text.

C:

Unbounded acceptance can create injection or storage errors. The parser needs defined Unicode support.

D:

Discarding identity data is not an acceptable interpretation. Preserve valid information.

Question 252

A release-note summarizer labels any feature with “legacy” in the name as officially deprecated. This creates false retirement notices. Which instruction best fixes it?

  1. Hide citations so readers cannot challenge a guessed status.
  2. Require explicit issuer language announcing deprecation or end-of-support, including effective date or uncertainty when absent.
  3. Assume “legacy” is synonymous with unsupported.
  4. Predict a deprecation date based on the name length.

Explanation

Correct Answer

B:

Product naming does not establish lifecycle status. A source-backed criterion prevents unsupported retirement claims.

Incorrect Answers

A:

Provenance is essential for time-sensitive product claims. Evidence should remain visible.

C:

Legacy can describe architecture or compatibility without a retirement deadline. The classification overreaches.

D:

Arbitrary heuristics invent lifecycle information. Only authoritative statements support a date.

Question 253

An AI parser extracts “remote access allowed” even from policies stating “remote access is not allowed except via approved VPN.” Which few-shot set is most useful?

  1. Examples contrasting full allowance, complete prohibition and conditional allowance, with the negation and exception spans labeled.
  2. Only examples where access is always allowed.
  3. Examples with the word “not” removed for consistency.
  4. No examples, only a directive to be confident.

Explanation

Correct Answer

A:

Boundary examples teach how qualifiers change the outcome. Extracting the precise clause prevents oversimplified permissions.

Incorrect Answers

B:

Positive-only examples reinforce the error and omit negative/conditional cases.

C:

Removing negation changes policy meaning. The model must learn to preserve it.

D:

Confidence is not semantic disambiguation. Representative labeled clauses are more useful.

Question 254

A tool schema requires a list of two distinct approver IDs for a high-value transaction. The model returns the same ID twice. What should validation enforce?

  1. Accept any two strings even if they identify the same person.
  2. Treat missing IDs as automatically approved.
  3. Replace the array with a free-form statement that approval occurred.
  4. Use the supported array/item schema and separately enforce exactly two distinct, authorized approver IDs in application validation before approval.

Explanation

Correct Answer

D:

The model-facing schema can require an array, but unsupported exact-length and uniqueness constraints need deterministic application checks. Two copies of one approver do not establish dual authorization.

Incorrect Answers

A:

Duplicated identity defeats separation of duties. The contract needs a distinctness rule.

B:

Absent approval should fail closed. The tool must not fabricate consent.

C:

Prose is not a verifiable approval record. Structured identities and checks are necessary.

Question 255

An extraction model reads a scanned invoice where the last digit of `total_due` is clipped. It outputs a plausible amount. Which correction loop is defensible?

  1. Approve if the JSON passes numeric schema checks.
  2. Drop the total field but mark the invoice completely extracted.
  3. Flag the source field as uncertain, retry with targeted image evidence, and escalate rather than invent an exact digit.
  4. Set the digit to zero because that is common in invoices.

Explanation

Correct Answer

C:

Validation includes evidence completeness, not just parseable numbers. Financial totals should not be guessed from an obscured image.

Incorrect Answers

A:

A syntactically valid number can still be factually unsupported. Provenance and clarity matter.

B:

The required value remains unresolved. Incomplete output should be explicit.

D:

A common pattern cannot establish the actual amount. Guessed values can misroute payments.

Question 256

A batched classification job finishes individual requests in a different order from submission. The client maps results by array position and assigns wrong labels to documents. What should change?

  1. Discard all document identifiers to reduce output size.
  2. Correlate results using the original unique custom request IDs, independently of arrival order.
  3. Sort results by their text length and align with the input list.
  4. Assume the first returned result belongs to the first submitted document.

Explanation

Correct Answer

B:

Asynchronous batches do not promise order. Stable IDs prevent cross-document misclassification.

Incorrect Answers

A:

Removing IDs prevents traceable reconciliation. The small metadata cost is justified.

C:

Length does not identify the source item. Reordering can make mismatches worse.

D:

Completion order is not necessarily submission order. Identity-based joins are required.

Question 257

An architecture review panel asks three specialist agents to produce independent critiques. The first reviewer’s favorable verdict is shown to the others before they inspect the design. What is a better method?

  1. Ignore any dissenting review automatically.
  2. Collect independent evidence-backed assessments first, then conduct a separate reconciliation pass on disagreements.
  3. Have every reviewer restate the first verdict in different words.
  4. Choose whichever reviewer has the highest self-reported confidence.

Explanation

Correct Answer

B:

Independent first readings reduce anchoring. Later synthesis can compare trade-offs without losing original observations.

Incorrect Answers

A:

Dissent may identify the only material defect. It should be assessed rather than suppressed.

C:

Rephrasing consensus does not supply independent validation. Shared bias remains.

D:

Confidence alone is not evidence quality. Claims need source or test support.

Question 258

A coordinator spawns three search agents for one confidential merger investigation. One worker requests unrelated HR folders. What is an appropriate delegation policy?

  1. Hide worker search history so the access cannot be audited.
  2. Let workers exchange credentials with each other to overcome access denials.
  3. Give each worker only the authorized document collection and case scope, with retrieval permissions enforced separately.
  4. Allow all workers to browse HR records because the overall investigation is confidential.

Explanation

Correct Answer

C:

Specialist roles do not justify browsing unrelated employee records. Narrow access reduces accidental disclosure.

Incorrect Answers

A:

Audit trails are useful for detecting scope violations. Suppression increases risk.

B:

Credential sharing bypasses authorization and destroys attribution. Legitimate access must be granted centrally.

D:

Confidentiality alone does not authorize unrelated access. Need-to-know still applies.

Question 259

An agent has a `send_notice` tool that can trigger a legally binding termination notice. Its description only says “sends messages.” What is the critical improvement?

  1. Send notices to every contact so the intended recipient is not missed.
  2. Describe the binding effect, required recipient and authority checks, validation inputs and irreversible consequences in a dedicated tool contract.
  3. Rename it to `send` without describing legal consequences.
  4. Allow any user to send termination notices if the prompt contains the word “urgent”.

Explanation

Correct Answer

B:

Precise semantics help the model choose correctly, while the host enforces authorization before sending. A generic message description hides high impact.

Incorrect Answers

A:

Broadcasting a binding notice risks serious unintended effects. Recipient specificity is mandatory.

C:

A shorter name does not communicate side effects. The tool needs an explicit contract.

D:

Urgency is not authority. High-impact notices require trusted approval.

Question 260

A bulk import MCP tool accepts 100 contacts; three have invalid email addresses. The API currently fails silently with no explanation. Which response is best?

  1. Discard all validated contacts without telling the caller which failed.
  2. Replace invalid email values with arbitrary addresses.
  3. Return per-record outcomes with stable IDs, field-level validation errors and explicit overall partial status.
  4. Mark all 100 contacts imported successfully regardless of rejected rows.

Explanation

Correct Answer

C:

The client can correct only three bad contacts and preserve 97 valid outcomes. Explicit identity and status prevent duplicate imports.

Incorrect Answers

A:

Lack of detail causes unnecessary retries and may duplicate valid imports. Precise errors are more useful.

B:

Invented contacts can misdirect communications. The caller should supply corrected data.

D:

False success corrupts downstream assumptions. Actual per-record state is required.
