Question 360

A support agent escalates a billing dispute after an API failure. The human operator receives only the customer's greeting and no prior tool history. What handoff would prevent redundant work?

  1. Mark the case closed and ask the operator to open a new one.
  2. Send only the agent's final apologetic sentence.
  3. Send the verified case/customer reference, disputed amount, facts, tools attempted, specific failure and pending decision in a structured case record.
  4. Include credentials and irrelevant private transcripts for every customer.

Explanation

Correct Answer

C:

A concise relevant history lets the operator act without repeating the full investigation.

Incorrect Answers

A:

Discarding the existing case obscures failure and delays resolution.

B:

Apology wording does not convey the unresolved work.

D:

Broad disclosure is unnecessary and unsafe.

Question 361

A research subagent queried an external registry twice; both calls timed out, but it did retrieve a valid cached excerpt from another source. What should it return to the coordinator?

  1. A declaration that the full source search succeeded because something was cached.
  2. Only an empty list of registry results, implying the query completed with no matches.
  3. The timeout category, attempts, affected registry query, partial verified excerpt and remaining evidence gap.
  4. A retry request that omits all attempted filters and prior errors.

Explanation

Correct Answer

C:

Error context and partial success support a targeted fallback and accurate scope statement.

Incorrect Answers

A:

One cached excerpt does not cover an unavailable primary query.

B:

A timeout cannot establish that the registry contained no records.

D:

The next worker may repeat the same failing access path.

Question 362

A research coordinator receives an agent's completed knowledge-base search yielding no articles for a rare model error. The agent's handoff omitted which index and filters were searched. Select TWO statements that preserve useful evidence without claiming that all possible sources were exhausted.

  1. Use a matching article from a neighboring product line without disclosing that its relevance was not checked.
  2. Repeat the identical lookup until it produces a result, without recording the already completed zero-match search.
  3. Label the result `isError:true` because the returned list is empty.
  4. Record that the specified knowledge-base lookup completed with zero matches, explicitly limiting that statement to the searched index.
  5. Include the index version, attempted query and filters in the handoff so an authorized follow-up can search other relevant sources.

Explanation

Correct Answers

D:

A no-match result is a scoped observation, not proof that every source lacks guidance. The coordinator can report the completed query honestly without misclassifying the tool as failed.

E:

Coverage and provenance metadata let downstream teams decide what evidence remains missing. This differs from the transport-level success versus error semantics tested separately in the MCP section.

Incorrect Answers

A:

An adjacent product's guidance may not apply to this model error. Without an explicit qualification it would falsely imply that the searched knowledge base returned a supported match.

B:

A normal no-match outcome does not imply a transient service failure. Repeating the same scoped query without a reason adds latency and loses useful coverage evidence.

C:

Empty success is not automatically a tool execution failure.

Question 363

A documentation subagent receives HTTP 403 from a restricted source but reports `[]` to its coordinator. What should be changed?

  1. Keep `[]` because the consumer expects a list even for errors.
  2. Preserve the permission-denied status and the blocked source identifier, explicitly distinguishing inaccessible evidence from zero matching documents.
  3. Use a less restricted user’s token from a previous case to repeat the blocked retrieval.
  4. Claim that no relevant documents exist because the first request did not return content.

Explanation

Correct Answer

B:

A 403 means the source was not successfully searched, so emptiness cannot be inferred.

Incorrect Answers

A:

A result shape should not conceal failure semantics.

C:

Credential reuse across principals would violate the access boundary. A 403 requires a properly authorized channel or an explicit missing-source limitation.

D:

No-access is not a factual search result.

Question 364

A multi-agent market report cannot reach one licensed data source but has strong verified evidence from two public datasets. What should its synthesis state?

  1. Claim every requested source was checked to avoid an incomplete-looking report.
  2. Discard all verified public evidence without assessing relevance.
  3. Estimate the inaccessible dataset from correlated public trends but describe the estimate as observed licensed data.
  4. Proceed only with clearly qualified coverage, identifying the missing source and any conclusions that cannot be supported without it.

Explanation

Correct Answer

D:

Partial evidence can be useful if limits are honestly reported.

Incorrect Answers

A:

A failed dependency cannot be converted into a completed review.

B:

One missing source does not necessarily invalidate all independent findings.

C:

Inferences may be reported as clearly labeled estimates, but they cannot stand in for the inaccessible source’s actual measurements.

Question 365

A research worker timed out on its first lookup but recovered with a bounded retry and then delivered a valid cited result. How should its completion record describe the error?

  1. Omit the successful result because any earlier error permanently invalidates the job.
  2. Escalate every recovered timeout as unresolved and block all downstream work.
  3. Mark the task successful with an observable retry trace, final source result and no unresolved access gap.
  4. Claim the first request succeeded without retries.

Explanation

Correct Answer

C:

The error history remains useful, but a recovered transient problem should not be reported as an active blocker.

Incorrect Answers

A:

Successful authenticated evidence can resolve a transient failure.

B:

A completed result should not be treated as missing evidence.

D:

Rewriting history obscures operational reliability.

Question 366

A refund request is rejected because a verified customer exceeds a nonoverrideable policy limit. The tool returns a structured nonretryable business error. What should the agent do?

  1. Hide the rejection and tell the customer the refund succeeded.
  2. Remove the policy field from the request and repeat the transfer.
  3. Retry the same request indefinitely until the backend responds differently.
  4. Explain the applicable limit and available authorized alternatives, without repeating the identical rejected call.

Explanation

Correct Answer

D:

A deterministic policy rejection requires a changed valid condition or human route, not a network retry.

Incorrect Answers

A:

This contradicts the real transaction outcome.

B:

Bypassing enforcement attempts an unauthorized action.

C:

Policy validation is not a transient availability issue.

Question 367

A tool rejects `date=30/10/26` because it accepts only ISO `YYYY-MM-DD`. What response enables a safe corrected next call?

  1. Mark the request successful but omit the date.
  2. Return `internal error` with no field details.
  3. Return a validation error identifying `date`, the accepted format and whether a verified source date is available for conversion.
  4. Generate today's date as a substitute whenever parsing fails.

Explanation

Correct Answer

C:

Precise feedback can correct representation without fabricating a date.

Incorrect Answers

A:

A missing required field means the operation did not complete.

B:

A generic error makes targeted correction difficult.

D:

The requested date may differ from the current date.

Question 368

A research specialist returns only 'search unavailable' when its approved index connector times out. What context should it give the coordinator?

  1. Fill the failed index result with a cached query from a different scope without marking the stale provenance.
  2. Include the affected index, attempted query or document scope, failure type, partial results if any and authorized fallback options.
  3. The API token so the coordinator can post it into another model prompt.
  4. A generic one-word failure with no identity of the missing source.

Explanation

Correct Answer

B:

Specific scope makes it possible to retry or qualify the final report.

Incorrect Answers

A:

A different or older search cannot prove what the requested index would return. The coordinator needs an explicit timeout and relevant prior attempt details.

C:

Leaking credentials is neither necessary nor safe.

D:

The coordinator cannot assess coverage or recovery from that response.

Question 369

Three parallel research workers finish: two return cited findings and one fails on a restricted endpoint. How should aggregation behave?

  1. Fill the missing worker result with another specialist's output and omit the failed workstream from the coverage report.
  2. Retain the two supported finding sets, record the third worker's explicit failure and decide whether the final claim requires the missing source.
  3. Discard all successful findings by default because one worker failed.
  4. Conclude that no restriction-related evidence exists because the worker failed to access it.

Explanation

Correct Answer

B:

Mixed results call for transparent partial aggregation and targeted recovery.

Incorrect Answers

A:

Unrelated findings cannot stand in for the missing specialization. A coordinator should retain successful work and explicitly mark the unresolved leg.

C:

Unrelated valid work need not be repeated or thrown away.

D:

Unavailable sources cannot support a negative finding.

Question 370

A summarizer receives `rows:[]` from a successful query and `rows:[]` from a failed query whose adapter swallowed HTTP 500. What should the integration layer preserve?

  1. Treat both as valid evidence of zero rows.
  2. An explicit success/error status, operation identifier and source scope in addition to the collection data.
  3. Treat every empty search as a server outage.
  4. Remove the status fields to make the schema smaller.

Explanation

Correct Answer

B:

Empty data cannot distinguish a genuine no-match search from an unexecuted request.

Incorrect Answers

A:

A server error gives no such evidence.

C:

Valid no-match queries should not become false failures.

D:

Losing error semantics makes the summaries unreliable.
