Question 40

A dependency-analysis subagent failed because its source-control read permission was revoked. The coordinator wants to retry with an alternate approved source. What must be included in the new worker invocation?

  1. Only the original high-level question; prior attempts and errors are never relevant to new invocations.
  2. An assertion that the inaccessible repository was fully scanned.
  3. The relevant prior findings, the exact access failure, attempted path and the authorized fallback scope.
  4. The administrator's private credentials so the retry can bypass permissions.

Explanation

Correct Answer

C:

The coordinator can pass a concise error history, partial evidence and accepted fallback route. This allows an informed retry without leaking unrelated state or fabricating permissions.

Incorrect Answers

A:

Fresh subagent invocations do not automatically know what happened earlier. Omitting failure context invites repeating the same unsuccessful access path.

B:

A permission failure is not proof of successful scanning. Claiming otherwise would make the final report falsely comprehensive.

D:

A subagent should not receive privileged credentials to circumvent a deliberate access control. Permission changes require authorized channels, not secret sharing in prompts.

Question 41

During a 200-page document investigation, search results contain large intermediate extracts. The coordinator must keep enough context for final decisions. Which architecture limits context bloat?

  1. Copy every raw extract from every specialist into the coordinator's message history after each step.
  2. Ask all specialists to omit evidence and report only 'complete' or 'failed'.
  3. Keep verbose inspection in bounded specialist contexts and forward concise attributed findings plus references.
  4. Have the coordinator discard all references and trust its first unsourced summary.

Explanation

Correct Answer

C:

Isolated specialist contexts hold verbose exploration while the coordinator receives structured results and stable source pointers. This preserves decision quality without repeatedly reloading all source text.

Incorrect Answers

A:

Accumulating every raw snippet can exhaust context and obscure critical conclusions. The main agent usually needs the distilled decision evidence, not all exploratory traffic.

B:

A bare status cannot support source-grounded conclusions or uncertainty resolution. The coordinator needs more than a success indicator.

D:

Removing references defeats provenance and impedes targeted follow-up. Compression should preserve claim evidence rather than replace it with unverified recollection.

Question 42

A research coordinator reassigns a specialized topic to a second worker. Its prompt provides the same broad mission but no specific jurisdiction, time range, or exclusions. What is the principal risk?

  1. The worker may duplicate previous searches and omit the intended narrow evidence because its boundaries are unclear.
  2. The worker will automatically infer the exact current customer's jurisdiction from the model name.
  3. The worker will refuse to work unless it receives the coordinator's complete historical transcript.
  4. The worker's first output becomes legally binding because the task has no limits.

Explanation

Correct Answer

A:

Without explicit topic, date and source boundaries, the worker can search the wrong material or repeat completed work. Defining the narrow unanswered question improves relevance and reduces duplication.

Incorrect Answers

B:

Model identity does not supply private customer facts such as jurisdiction. The delegation needs verified scope information from the active case.

C:

The full transcript is usually unnecessary and may include irrelevant sensitive context. A carefully scoped task brief with targeted evidence is preferable.

D:

An unclear delegated task is not a source of legal authorization. Outputs remain analysis subject to verification and the service's established governance.

Question 43

A team configures an AgentDefinition for a specialized QA reviewer with a system prompt but no role description. The coordinator rarely selects it when relevant. What should the team improve?

  1. Increase the model's temperature so the reviewer gets invoked more often by chance.
  2. Describe the reviewer’s purpose, inputs, typical triggers and outputs clearly in its registered definition.
  3. Rename the reviewer to a single generic name shared by all other agents.
  4. Give the reviewer permission to approve every downstream business action.

Explanation

Correct Answer

B:

Clear agent descriptions help the coordinator recognize when a specialist matches a question. They should state the review boundary and expected evidence so it can be invoked for appropriate work.

Incorrect Answers

A:

Randomizing selection does not clarify when this specialist should be used. Better routing follows explicit capability definitions and the coordinator's task analysis.

C:

Giving all specialists the same generic label increases ambiguity rather than improving role selection. Distinct responsibilities should be discoverable.

D:

An agent's lack of description does not justify granting it business approval powers. Tool access should stay narrowly scoped to actual QA needs.

Question 44

A cited research report must combine findings from four subagents. Each agent has returned a different mix of text, footnotes and page references. How should the coordinator combine them?

  1. Concatenate the paragraphs and rely on the final model to remember which footnote came from which worker.
  2. Remove all metadata fields so the synthesis input is shorter.
  3. Merge the findings under structured claim IDs with source locators, qualifiers and producing-agent status.
  4. Sort the findings alphabetically by agent nickname and treat that order as evidence priority.

Explanation

Correct Answer

C:

A structured merge preserves each atomic claim's provenance and confidence limits. The coordinator can then deduplicate, reconcile conflicts and produce an auditable synthesis.

Incorrect Answers

A:

Plain concatenation can misattach citations, especially when multiple workers use similar numbering. Report generation needs stable source linkage, not a guess based on position.

B:

Discarding source metadata reduces text length but sacrifices verifiability. A concise structured record can be compact while retaining the critical fields.

D:

Alphabetical worker naming is unrelated to claim reliability. Evidence priority should follow quality, currency and relevance rather than labels.

Question 45

Two subagents are asked to edit the same configuration file concurrently. Each proposes a different valid change, and the second completion overwrites the first. What design correction would avoid this conflict?

  1. Run all workers with unrestricted write access because last-writer-wins is simplest.
  2. Prohibit any parallel analysis, even of independent files.
  3. Deploy whichever branch finished last and treat its timestamp as proof that earlier valid edits are included.
  4. Assign disjoint edit ownership or route proposed changes through a coordinator-controlled merge and conflict check.

Explanation

Correct Answer

D:

Clear file ownership boundaries prevent concurrent mutation collisions. When shared edits are unavoidable, centralized merge with version checks can detect and resolve conflicting changes deliberately.

Incorrect Answers

A:

Uncoordinated writes can destroy earlier changes and produce an invalid combined configuration. Simplicity does not justify silent overwrite.

B:

Parallelism is safe for independent read or edit domains. The failure comes from shared mutable state, not all concurrency.

C:

A last-writer-wins rule does not merge distinct modifications. It can silently lose one change when concurrent agents edit the same base version.

Question 46

A certification guide calls the delegation capability 'Task', while the deployed Agent SDK documentation exposes an 'Agent' tool for subagents. What should the integration engineer do?

  1. Use the delegation tool name from the certification guide without checking which SDK version is actually deployed.
  2. Inspect the installed SDK/tool API, bind the appropriate permitted delegation capability and record the version-sensitive name.
  3. Hide the discrepancy and tell operators both tools definitely behave identically in every release.
  4. Remove all explicit tool permissions so the model can guess which agent tool exists.

Explanation

Correct Answer

B:

The architect should respect the actual installed tool contract. The stable principle is explicit subagent delegation and scoped permissions; the concrete API name must match the deployed version.

Incorrect Answers

A:

Guide examples may describe an earlier API surface. A supported delegation tool must be discovered from the installed version rather than presumed from a historical example.

C:

Different releases may change configuration names or behavior. Claiming universal equivalence is unsupported and can mislead maintainers troubleshooting a production system.

D:

Removing tool constraints is unsafe and does not guarantee availability of a missing API. Discover and configure the supported interface deliberately.

Question 47

A coordinator wants to send a complete 30,000-line search transcript into a specialized subagent that only needs three risk findings. What is the strongest context-selection choice?

  1. Pass the three relevant findings, verified facts and source pointers in a bounded structured briefing.
  2. Pass the entire transcript because larger prompts always improve accuracy.
  3. Pass only the customer's first name so the specialist must rediscover all requirements.
  4. Keep only document titles in the compacted briefing and ask the specialist to reconstruct precise citation anchors later.

Explanation

Correct Answer

A:

The specialist needs task-relevant evidence and constraints. A concise briefing with stable source identifiers preserves auditability while avoiding unnecessary context pressure.

Incorrect Answers

B:

More text can dilute important details and consume context available for reasoning. Huge raw logs are better retained in referenced storage or the originating worker's scope.

C:

A name is neither a task brief nor an evidence handoff. It omits the very risk findings the coordinator already collected.

D:

Titles are not enough to reproduce claim-level citations. An evidence handoff should preserve the actual source ID and locator from the originating research rather than force reconstruction.

Question 48

A coordinator receives a subagent response reading 'done' but no structured claim list, coverage notes or errors. The customer needs a cited report. What response is appropriate?

  1. Declare the full report complete because the subagent returned a completion word.
  2. Treat the worker as successful and cite arbitrary documents from the user's folder.
  3. Request or require structured findings, evidence anchors, coverage and error status before aggregation.
  4. Treat the worker's completion flag as an implicit success and draft the report from the coordinator's original assumptions.

Explanation

Correct Answer

C:

The coordinator needs a result contract rather than a conversational completion heuristic. Structured findings and limitations make synthesis and targeted recovery possible.

Incorrect Answers

A:

A status word does not provide information supporting a report. It cannot establish that the specialist covered the assigned work or found no relevant evidence.

B:

Citing unrelated documents would create the appearance of support without an actual claim-source connection. That fails the report's evidentiary requirement.

D:

A status signal cannot replace claim-level findings and source anchors. The requested evidence must be returned or reported missing.

Question 49

An order agent receives a request to refund $240. The order record exists, but identity verification is still pending. How should the payment integration behave?

  1. Tell Claude in its prompt to verify identity but let every refund tool call pass.
  2. Reject process_refund at the executable authorization boundary until verified customer identity is bound to this order.
  3. Process the refund and request identification afterward to minimize wait time.
  4. Accept a matching customer first name as equivalent to verified account ownership.

Explanation

Correct Answer

B:

A server-side prerequisite protects funds even if the model tries to invoke the payment tool prematurely.

Incorrect Answers

A:

Prompt wording cannot enforce a dependency when the payment endpoint remains callable.

C:

Post-transaction checks cannot undo an unauthorized transfer.

D:

Display names are not stable proof of authority over a specific transaction.

Question 50

A shopper asks where an overdue parcel is and why the card shows a second charge. The coordinator has shipping and billing specialists. What plan best addresses both issues?

  1. Route everything to shipping because the parcel question appeared first.
  2. Request a refund before investigating either transaction or shipping status.
  3. Open two scoped workstreams against the verified order and reconcile their findings into one accurate response.
  4. Have both specialists independently repeat the full chat analysis and issue separate customer replies.

Explanation

Correct Answer

C:

Separate concerns permit parallel investigation without losing the relationship to the same order.

Incorrect Answers

A:

A shipping agent cannot establish the nature of the extra payment.

B:

Initiating money movement would prejudge the dispute and bypass policy checks.

D:

Duplicated work may produce inconsistent conclusions and no accountable combined answer.
