Question 290

An MCP search tool returns 80 valid records and then loses its paging cursor while fetching the next page. How should it report status?

  1. Delete the 80 valid results because later paging failed.
  2. Invent the missing records based on prior page patterns.
  3. Return validated records with a partial-completion status, cursor failure details and a safe retry hint.
  4. Return success with a claim that the full dataset was inspected.

Explanation

Correct Answer

C:

A partial result is neither a complete success nor invalid data. The caller can preserve evidence and repair the missing tail.

Incorrect Answers

A:

Discarding known-good data increases unnecessary work and loses evidence.

B:

Synthetic rows cannot replace authoritative search results.

D:

The missing pages make a completeness claim false.

Question 291

An export agent must verify eligibility before a separate approved service sends customer data. The platform exposes a send tool by default. How should its permissions be scoped?

  1. Expose only read-only eligibility tools to the verification agent, with sending held behind an independent authorized phase.
  2. Expose the send tool and rely entirely on the instruction do not send.
  3. Allow the verification worker to call the send tool in a trial mode that lacks a host-enforced no-send guarantee.
  4. Use an unrestricted global tool set for every child agent.

Explanation

Correct Answer

A:

Agent-specific capabilities protect the handoff boundary; checking eligibility is not consent to transmit data.

Incorrect Answers

B:

Prompts alone are weaker than actually withholding sensitive capabilities.

C:

A tool labelled preview can still transmit data unless the host enforces a non-mutating mode. Eligibility review should not hold a send capability at all; a separate authorized phase performs transmission.

D:

Overbroad tools increase the impact of errors and prompt injection.

Question 292

After a server upgrade, a report tool now requires a tenant_id field. An old agent call fails validation. What is the safest response?

  1. Read the updated server tool schema, supply a verified tenant identifier, and retry only after permission validation.
  2. Guess a tenant ID from another user’s previous report.
  3. Bypass input validation to keep the old payload working.
  4. Send an empty tenant ID and declare a successful report.

Explanation

Correct Answer

A:

Schema evolution must be handled explicitly. A tenant identifier is also an access-control boundary.

Incorrect Answers

B:

Cross-tenant guessing can cause misrouting and unauthorized access.

C:

Disabling schema checks increases risk and does not repair the changed contract.

D:

A placeholder cannot establish tenant selection or completed retrieval.

Question 293

An agent repeatedly suggests the same code patch after a test failure, despite identical test logs. The host has a limited retry budget. What should it detect?

  1. Declare the patch applied because it was proposed multiple times.
  2. Clear all failure logs so the agent can reason more optimistically.
  3. Repeated unchanged patch/test state and lack of progress, then stop with a precise unresolved diagnosis.
  4. Continue forever because repeated reasoning increases certainty.

Explanation

Correct Answer

C:

A progress gate prevents costly circular attempts while preserving the actual failed evidence.

Incorrect Answers

A:

A suggestion is not an executed edit or a passing test.

B:

Removing evidence makes debugging less reliable.

D:

Identical actions and evidence do not justify unbounded retries.

Question 294

A coordinator asks a contract-reading subagent whether a refund is allowed. The subagent reports that it appears allowed, but no refund authorization tool was called. What should happen?

  1. Treat the finding as analysis and invoke the distinct authorized refund decision gate before any transfer.
  2. Pay immediately because the subagent used a trusted legal document.
  3. Allow the subagent to assign itself payment permissions.
  4. Report the refund completed without invoking the payment service.

Explanation

Correct Answer

A:

A worker interpretation is not a transaction approval. Authority remains with the guarded execution path.

Incorrect Answers

B:

A grounded interpretation can inform but does not replace the required approval workflow.

C:

Workers must not escalate their own capabilities to execute financial side effects.

D:

A claim of completion needs the actual transaction result.

Question 295

A records agent requests approval to delete a dataset. After approval, the selection changes from 200 records to 900. What should execution enforce?

  1. Delete all 900 because approval was once given for a similar request.
  2. Use the requester’s job title as a substitute for a scope check.
  3. Hide the record-count change to avoid wasting approver time.
  4. Require approval bound to the exact validated dataset selection or digest; reauthorize when the target changes.

Explanation

Correct Answer

D:

Scope-bound approval prevents an old consent artifact authorizing a broader destructive action.

Incorrect Answers

A:

The expanded target exceeds the original permission.

B:

A role does not prove authorization for the changed exact deletion set.

C:

Concealing material scope drift undermines informed consent.

Question 296

A security agent receives a telemetry finding that may indicate either a sensor clock error or an actual unauthorized login. The two cases require different next actions. Which workflow shape is best?

  1. Normalize every suspicious timestamp using an assumed sensor offset before checking the time source or sign-in evidence.
  2. Choose a branch randomly to keep response times consistent.
  3. Branch on verified timestamp and identity evidence, then execute the appropriate clock-repair or incident-response path.
  4. Perform destructive incident containment for every timestamp mismatch.

Explanation

Correct Answer

C:

Conditional decomposition avoids treating a mere time anomaly as a confirmed attack while preserving escalation for genuine misuse.

Incorrect Answers

A:

Blindly applying an assumed offset could erase a genuine impossible-travel signal. First verify sensor clocks and session/identity evidence, then branch to clock repair or incident response accordingly.

B:

Branching must be justified by evidence and policy.

D:

Unconditional containment can disrupt operations when the cause is a monitoring defect.

Question 297

An agent is about to export private customer records, but the consent-verification service is unavailable. The user says the export is urgent. What state and action are defensible?

  1. Email the records to the agent developer to validate the account.
  2. Do not export, mark authorization unverified, and use an approved retry or escalation path.
  3. Send the records because urgency implies consent.
  4. Mark authorization denied permanently based only on service unavailability.

Explanation

Correct Answer

B:

A failed approval lookup is not consent. The side-effect gate should fail closed while explaining the blocker.

Incorrect Answers

A:

A new recipient would compound the unauthorized disclosure risk.

C:

Urgency cannot independently establish authorization for private data.

D:

Unknown due to tool failure is distinct from an affirmative denial.

Question 298

An invoice analysis worker finished with a validated total. A separate tax-check worker timed out. How should an orchestrator record the combined state?

  1. Keep the verified invoice result and mark the tax component pending or failed, withholding any tax-dependent completion claim.
  2. Erase the invoice result because a different worker timed out.
  3. Publish the tax result as zero because no response arrived.
  4. Mark the entire assessment fully complete because one worker succeeded.

Explanation

Correct Answer

A:

Per-component states preserve usable evidence without misrepresenting the missing requirement.

Incorrect Answers

B:

Unnecessary rollback destroys valid progress and increases rework.

C:

A timeout is not a computed zero tax liability.

D:

Partial success cannot certify the unresolved required calculation.

Question 299

A code-analysis subagent finds a security-sensitive authorization helper, but its long context is being compacted. What should the summary preserve?

  1. The entire unrelated dependency lockfile, omitting the helper location.
  2. An ungrounded assurance that all authorization code is safe.
  3. Repository path, symbol name, relevant call sites, security assumptions and unresolved tests.
  4. Only the fact that many files were inspected.

Explanation

Correct Answer

C:

A concise code map keeps high-value dependencies retrievable without copying the whole repository.

Incorrect Answers

A:

Bulk unrelated text displaces the finding that matters to subsequent analysis.

B:

A summary should preserve evidence and open questions, not invent a blanket pass.

D:

Inspection volume does not identify where the relevant authorization behavior lives.

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.
