Question 30

An agent platform has search, extract, verify and report specialists connected in an unrestricted peer-to-peer mesh. Auditors cannot reconstruct which worker approved a contradictory source claim. What architecture best improves accountability?

  1. Give each agent access to a single global mutable answer field so all decisions converge instantly.
  2. Ignore the source disagreement if the final report has a fluent writing style.
  3. Authorize a provisional refund while the two policy interpretations are reconciled, planning to reverse it if needed.
  4. Use coordinator-mediated handoffs with recorded producer, source identifiers, status and decision history.

Explanation

Correct Answer

D:

Central orchestration permits consistent evidence labeling, exception handling and clear decision ownership. A coordinator can trace which specialist produced and verified each claim before including it in the output.

Incorrect Answers

A:

A shared mutable answer field loses individual provenance and lets agents overwrite each other's findings. It does not create an auditable decision trail.

B:

Readability cannot establish evidence quality. A report may be polished while misrepresenting contradictory or stale claims.

C:

A payment side effect can be difficult or impossible to reverse. Conflicting authorization evidence is a reason to withhold the transaction until the applicable eligibility rule is resolved.

Question 31

A research coordinator sees that two document batches are independent but the final synthesis must reconcile sources across both. Which execution plan best balances speed and coherence?

  1. Run document workers independently in parallel, then have the coordinator compare findings and synthesize by source-backed claim.
  2. Wait for the first document batch to finish, synthesize immediately, then silently ignore the second batch.
  3. Process both batches sequentially even when they share no mutable state or dependency.
  4. Let each worker publish a separate final answer without a coordination step.

Explanation

Correct Answer

A:

Independent extraction batches can run concurrently without interfering with each other. The coordinator still needs an aggregation phase to deduplicate findings, handle contradictions and preserve citation provenance in the final report.

Incorrect Answers

B:

Early synthesis from only the first batch leaves the second evidence population unexamined. It can misstate completeness and omit important counterexamples.

C:

Sequential processing is valid but unnecessarily lengthens latency when inputs and outputs are independent. Parallelism is safe here because the merge is deferred until both results are available.

D:

Separate final answers do not satisfy the request for one coherent account. They also force the user to reconcile duplicates or disagreements that the coordinator was designed to handle.

Question 32

A long-running multi-agent review of a retailer’s refund policy has conflicting findings: one specialist says a disputed transaction qualifies and another says the account is excluded. Which coordinator action best handles the conflict?

  1. Choose the first result to avoid an extra step.
  2. Check the controlling policy version, customer eligibility and both specialists’ evidence, then resolve the discrepancy or report an unresolved policy decision.
  3. Automatically process two refunds so at least one specialist's recommendation is fulfilled.
  4. Tell the customer policy is universally permissive because one worker supported a refund.

Explanation

Correct Answer

B:

A completed synthesis cannot pick a winner by response order. Checking the source clauses, account conditions and effective dates allows a justified decision; otherwise the coordinator should keep the refund action blocked and escalate the conflict.

Incorrect Answers

A:

Response order is not an eligibility rule. One worker may have evaluated a different product, policy version or customer identity.

C:

Issuing multiple payments in response to contradictory advice creates financial harm. No transaction should be made until authorization and eligibility are established.

D:

An isolated permissive output does not override a potentially applicable denial. Overriding policy based on one worker would risk an unauthorized transaction.

Question 33

A research coordinator invokes a document-analysis subagent that cannot see the previous web-search transcript. The analyst needs three specific search results to verify vendor claims. What should the coordinator provide?

  1. Nothing; subagents automatically inherit all previous assistant and tool messages.
  2. An explicit evidence bundle with the three relevant findings, URLs and the requested verification criteria.
  3. Only the name of the search worker, expecting the analyst to access that worker's private memory.
  4. The final report title without any source text, because a specialized agent can infer what was found.

Explanation

Correct Answer

B:

The delegation should include the pertinent search evidence, provenance and decision goal. A scoped bundle lets the analyst verify facts without needing unrelated conversation turns or hidden state.

Incorrect Answers

A:

Agent contexts are isolated unless explicitly configured and populated. Assuming shared history causes the specialist to miss essential source evidence.

C:

The worker name is not a data transfer mechanism. A distinct subagent does not ordinarily read another agent's private context without explicit handoff.

D:

A title communicates the end product but not the underlying facts. Verifying specific vendor claims requires the actual results and the criteria for acceptance.

Question 34

An Agent SDK coordinator is configured with specialists but never delegates work because the allowed tool list excludes the platform's subagent invocation capability. Which change fixes the missing mechanism?

  1. Add the current installed SDK's supported delegation tool to the coordinator allowlist and configure the specialists appropriately.
  2. Repeat 'delegate now' in the system prompt while leaving tool permissions unchanged.
  3. Pretend that multiple subagents were run by writing their names in the final answer.
  4. Give all subagents full administrative tools without changing the coordinator's permitted calls.

Explanation

Correct Answer

A:

Delegation requires an exposed and authorized invocation capability, known as Task in some guide-era examples and Agent in newer SDK contexts. The exact tool name should match the deployed version, with specialist definitions and restrictions in place.

Incorrect Answers

B:

A model cannot invoke a tool that its runtime forbids. Additional prompt urgency does not supply the missing executable capability.

C:

Listing agent names in prose is not equivalent to running those agents. It fabricates work and provides no independent findings or audit record.

D:

Broadening specialist privileges does not enable the coordinator to invoke them and creates unnecessary risk. Configure the caller's delegation permission rather than unrelated tool access.

Question 35

A legal team uploads three independent policy PDFs and asks a multi-agent research system to extract specific clauses. Each PDF can be read separately. Select TWO steps that produce efficient, auditable document analysis.

  1. Analyze the PDFs serially and wait for an assistant reply after each even when no dependency exists.
  2. Send all three PDFs in one unstructured prompt and ask for a single unsupported global conclusion.
  3. Issue independent scoped analysis requests concurrently, then merge the returned clause records by source.
  4. Skip the PDF evidence and ask the agents to infer likely policies from document titles.
  5. Require each worker to preserve the PDF identifier, clause text and page/section anchors in its returned findings.

Explanation

Correct Answers

C:

Independent subagent calls can run in parallel and return structured clause, locator and document identifiers. The coordinator then reconciles overlapping or conflicting provisions before summarizing.

E:

Parallel extraction accelerates independent reads, but recorded source locations make the later merged clause list checkable rather than a collection of untraceable quotations.

Incorrect Answers

A:

Serial execution is possible but adds latency when the tasks do not depend on one another. The merge can happen after independent reads complete.

B:

A large undifferentiated prompt makes clause attribution and coverage difficult. The team needs identified findings from each document.

D:

Titles provide no evidence of the actual clauses. Omitting source inspection would misrepresent the contracts and defeat the extraction task.

Question 36

A synthesis worker receives a note saying 'Clause 4 limits data retention' but no document identity or page. The system must make each conclusion auditable. What context format should replace the note?

  1. Only the text 'retention limited' repeated several times to reinforce the finding.
  2. The complete coordinator chat history, including unrelated customers' personal information.
  3. An agent-authored citation string generated later from memory.
  4. A structured finding with claim text, source document ID, page or anchor, and relevant qualification.

Explanation

Correct Answer

D:

Separating claim content from source metadata lets the coordinator verify and cite it. A qualification field preserves exceptions or uncertainties that would otherwise be lost when compressing subagent notes.

Incorrect Answers

A:

Repetition does not add provenance or clarify which agreement controls the retention period. It may instead reinforce an unsupported assertion.

B:

An indiscriminate transcript dump would introduce irrelevant information and potential privacy exposure. The needed fields are narrow, source-linked and task specific.

C:

Later citation invention is prone to incorrect document names and page numbers. Source metadata should be carried from extraction through synthesis.

Question 37

A document-analysis subagent returns a claim table for a cited report, but the handoff drops document IDs and page or section anchors. What should the coordinator require before using the table?

  1. Assume every worker finished all assigned topics successfully unless one explicitly says 'error'.
  2. Return only a fluent executive summary, suppressing references to missing sources.
  3. Choose the longest worker response as authoritative and discard all others.
  4. Return typed claim records with the source document ID, original page or section anchor, confidence limits and any missing coverage.

Explanation

Correct Answer

D:

A row in a table is not verifiable without a link back to the exact document and source location. Structured claim records with stable page anchors and qualifiers preserve evidence through aggregation without copying the entire raw analysis transcript.

Incorrect Answers

A:

Successful-looking text can omit required topics or hide access failures. Completion needs explicit scoped status and coverage, not a default assumption.

B:

A fluent summary can mask source gaps if limitations are suppressed. The final report should distinguish supported claims from open uncertainties.

C:

Response length is unrelated to factual reliability or breadth. Other workers may carry critical contradictory evidence absent from the longest answer.

Question 38

A report-generation specialist needs only to read approved research notes and write a summary, yet its AgentDefinition allows unrestricted terminal commands and network writes. What should an architect change?

  1. Remove unnecessary tools, permitting only the bounded read and report-writing capabilities needed for the role.
  2. Keep all tools because the agent's friendly role description is sufficient protection.
  3. Send a user-facing warning while leaving dangerous capabilities fully available.
  4. Disable the coordinator's ability to receive findings so the specialist operates entirely unmonitored.

Explanation

Correct Answer

A:

Tool permissions should follow least privilege. A summary-only specialist can work with constrained evidence and output tools without acquiring shell or network mutation authority.

Incorrect Answers

B:

Role prose shapes behavior but does not deterministically restrict runtime capabilities. An agent exposed to irrelevant destructive tools may misuse them or be manipulated by untrusted content.

C:

A warning does not prevent execution of an unauthorized action. The enforcement boundary belongs in the actual allowed tool configuration and service permissions.

D:

Monitoring and handoff are useful safeguards. Eliminating the coordinator would reduce observability rather than address excessive tool rights.

Question 39

A coordinator delegates a complex audit and wants the worker to decide how to inspect the modules while still reporting concrete findings. Which instruction style is preferable?

  1. Supply an exact 200-step command script even though module dependencies are not yet known.
  2. Provide the audit goal, scope, acceptance criteria, permitted tools and expected evidence format, allowing the worker to choose relevant steps.
  3. Provide only the word 'audit' without codebase identifiers or quality criteria.
  4. Authorize arbitrary filesystem changes as an incentive for the worker to finish quickly.

Explanation

Correct Answer

B:

A scoped goal and evidence contract tell the specialist what success means without micromanaging exploratory reasoning. Runtime permissions and task boundaries remain explicit.

Incorrect Answers

A:

A rigid script may fail to account for discovered dependencies and can spend effort on irrelevant modules. It is less suitable when the investigation plan must adapt.

C:

An undefined one-word prompt omits the target, expectations and constraints. It cannot support reliable specialist routing or meaningful audit acceptance.

D:

Excess filesystem privileges neither improve audit reasoning nor justify mutation. A read-focused audit should not be given arbitrary destructive authority.

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.
