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.

Question 261

A deployment uses two supported model versions, one of which rejects forced named-tool selection. The application sends the same forced tool_choice to both, causing failures. What is the best correction?

  1. Check documented per-model tool-selection capabilities and use a supported mode with host-enforced authorization and result validation.
  2. Keep the unsupported setting and retry indefinitely.
  3. Disable all tool authorization checks to reduce model errors.
  4. Treat tool-choice failure as evidence the user has no permission.

Explanation

Correct Answer

A:

Tool-selection settings can vary by model. Runtime policy should not depend on forcing a tool when unsupported.

Incorrect Answers

B:

A deterministic capability mismatch does not resolve through retries. The request must be adapted.

C:

Authorization is separate from model capability. Removing it increases risk without fixing the API contract.

D:

An unsupported API option is a technical error, not an authorization decision. Error types must remain distinct.

Question 262

A connected MCP server version update adds a new `delete-records` tool. Existing agent configurations automatically expose all advertised tools. What should the owner do?

  1. Remove all tool invocation logging to speed upgrades.
  2. Assume every new tool is read-only until it executes.
  3. Re-review the tool registry and allowlist after upgrade, keeping newly destructive capabilities disabled until authorized.
  4. Enable all new tools because the server was previously trusted.

Explanation

Correct Answer

C:

Server upgrades can expand the attack surface. Explicit capability review prevents silent privilege increases.

Incorrect Answers

A:

Logs are important for detecting misuse. They should not be disabled.

B:

A destructive API cannot be tested safely by running it blindly. Tool semantics should be inspected first.

D:

Past trust in an old surface does not authorize newly added actions. Least privilege requires fresh review.

Question 263

A workspace transfer request names a manager whose email alias maps to two distinct directory accounts. The agent cannot verify which account is authorized to approve. What is appropriate?

  1. Use both accounts’ credentials to attempt approval until one succeeds.
  2. Skip approval because the manager’s name appears in the prompt.
  3. Hold the transfer, ask for an authoritative identity disambiguation and bind the final approval to the confirmed principal.
  4. Approve whichever account appears first in directory results.

Explanation

Correct Answer

C:

Name and alias collisions create material authorization risk. A targeted clarification prevents an irreversible transfer to the wrong owner.

Incorrect Answers

A:

Credential probing is unauthorized and undermines auditability. The workflow should resolve identity legitimately.

B:

A mention is not a signed authorization artifact. The gate remains required.

D:

Listing order has no authority meaning. The correct principal needs verification.

Question 264

A coordinator marks deployment verification failed because a child agent could not fetch build artifacts. The deployment itself has not been evaluated. Which status is most accurate?

  1. Blocked by artifact retrieval failure, with deployment validity unknown and a targeted retry path.
  2. Application code definitively failed tests.
  3. Deployment passed because no test failure was observed.
  4. Release artifacts do not exist anywhere because this fetch failed.

Explanation

Correct Answer

A:

An unavailable artifact is not proof the software is defective. Distinct statuses keep diagnosis and quality claims accurate.

Incorrect Answers

B:

No tests were run against the missing artifact. The cause is an upstream retrieval failure.

C:

Absence of executed checks is not a pass. Evidence is missing.

D:

One inaccessible source does not prove global nonexistence. The issue requires investigation.

Question 265

A coding agent reviews a pull request with two changed service files. It reads an unrelated 5,000-line internal wiki but misses the critical shared authentication library they call. What should retrieval prioritize?

  1. Load the largest document first because it contains more words.
  2. Review only filenames and skip source content.
  3. Assume the auth library is safe because it was not directly changed.
  4. Read changed code and relevant called authentication interfaces/tests first, then expand context only when findings justify it.

Explanation

Correct Answer

D:

Impact-oriented retrieval captures the actual dependency path. Unrelated wiki volume consumes attention without covering the security boundary.

Incorrect Answers

A:

Document size is not evidence relevance. The critical library should take priority.

B:

Names do not prove runtime behavior. Functions and tests need inspection.

C:

Changed callers can misuse existing interfaces. Dependencies remain relevant.

Question 266

A contract parser assigns confidence 0.99 to dates copied from the signature block, even when the effective date appears elsewhere. Users report wrong renewals. What should the team test?

  1. Evaluate date-field accuracy against adjudicated examples, including differing signature/effective dates, then tune threshold and source-location rules.
  2. Increase the confidence threshold to 0.999 without measuring errors.
  3. Always use the signature date regardless of contract language.
  4. Remove all renewal warnings so wrong dates have no visible effect.

Explanation

Correct Answer

A:

High confidence may be miscalibrated. Grounded examples reveal whether the extractor finds the legally applicable field.

Incorrect Answers

B:

A higher number does not fix wrong source selection if the model remains overconfident. Calibration requires data.

C:

Signature and effective dates can differ. The actual clause governs.

D:

Hiding consequences does not correct the data. The extraction logic must be repaired.

Question 267

A support agent calls a slow product inventory tool three times without results. The configured loop budget is exhausted, and no inventory status has been verified. What should it return?

  1. An explicit unresolved inventory status with the last verified facts and an appropriate retry or escalation path.
  2. Available, because three retries show determination.
  3. Sold out, because the tool did not respond.
  4. Continue tool calls indefinitely beyond the enforced budget.

Explanation

Correct Answer

A:

Bounded execution avoids runaway tool use. Honest uncertainty is preferable to fabricating stock availability.

Incorrect Answers

B:

Retry count has no causal relation to stock. The response would invent a business fact.

C:

Tool unavailability is not an inventory result. The two states must stay distinct.

D:

Ignoring limits violates the system’s resource and reliability policy. A clear stop condition is needed.

Question 268

A clinical scheduling agent sees an insurance coverage denial but an active appointment slot. One worker handles eligibility and another availability. What should the coordinator do?

  1. Book immediately because an appointment slot exists.
  2. Change the coverage result to approved because it conflicts with availability.
  3. Discard the slot details and tell the patient no appointments exist.
  4. Keep both findings separately, seek authorized eligibility resolution, and avoid booking a financially committed service until required conditions pass.

Explanation

Correct Answer

D:

Availability does not establish coverage. The coordinator must honor dependency rules and preserve each source’s meaning.

Incorrect Answers

A:

A slot alone does not satisfy coverage or payment policy. The other condition remains unresolved.

B:

Contradictory evidence must be reconciled, not overwritten. The coverage source remains authoritative for its domain.

C:

Coverage denial is not lack of availability. Distinct outcomes should remain clear.

Question 269

An agent drafts a public incident disclosure. It has confirmed technical facts but no communications approval. A retrieved blog says companies should publish quickly. What should govern release?

  1. A trusted communications approval and legal-policy gate verified before the public publishing tool is allowed.
  2. Publish immediately because technical evidence is strong.
  3. Allow the blog text to approve publication.
  4. Pretend the draft was published to satisfy the user.

Explanation

Correct Answer

A:

A public disclosure is consequential and must follow authorized review. External advice does not bypass governance.

Incorrect Answers

B:

Facts do not replace approval authority. The organization must control disclosure timing and content.

C:

A blog is untrusted external content, not an internal authorization artifact. It cannot grant tool permission.

D:

A false status claim damages trust. The agent should report the draft and pending approval accurately.

Question 270

An incident workflow must preserve volatile evidence when feasible, revoke a compromised session, and restore clean service. Which THREE planning principles support reliable execution? Select THREE.

  1. Always image persistent disks before acquiring process memory or volatile network state, even when that ordering destroys unrecoverable evidence.
  2. Treat initiation of a successful containment command as enough to release all recovery-stage dependencies.
  3. Give incident responders blanket standing authority for all cleanup and recovery tools while the incident remains open.
  4. Encode prerequisite dependencies so evidence capture and risk assessment inform any destructive remediation.
  5. Allow independent read-only log collection across systems concurrently when permissions permit.
  6. Define success, failure and escalation outcomes for each stage before moving to recovery.

Explanation

Correct Answers

D:

Sequencing prevents loss of material artifacts when possible. The DAG can represent operational safety exceptions explicitly.

E:

Independent evidence-gathering tasks can run in parallel, reducing response time without bypassing dependencies.

F:

Explicit state transitions prevent the coordinator from reporting restoration before required conditions actually pass.

Incorrect Answers

A:

Persistent imaging can be important, but an inflexible order can lose volatile artifacts before capture. The dependency plan must consider evidence volatility, live system safety, and authorized containment.

B:

A command invocation is not a verified outcome and does not confirm that forensic, eradication, or recovery prerequisites completed. Each stage needs an independent success or failure result.

C:

Incident response needs rapid action, but standing unrestricted destructive permissions can damage evidence or production systems. Authorization should be scoped to stage, system, and approved recovery operation.
