Question 590

A repository CLAUDE.md contains hundreds of pages of historical design discussions. Agents regularly miss the few mandatory build commands. What structure is better?

  1. Keep essential commands and constraints concise in project memory and link optional background documents by topic.
  2. Append even more historical transcripts to the root file.
  3. Delete mandatory commands so the file is shorter.
  4. Put build instructions inside an unrelated generated image.

Explanation

Correct Answer

A:

High-signal instructions are easier to apply when irrelevant history is not always loaded.

Incorrect Answers

B:

Additional volume can bury critical requirements.

C:

Conciseness should not remove essential workflow controls.

D:

A nontext artifact is not a reliable instruction location.

Question 591

A researcher subagent investigating a code vulnerability is given a development server shell with deployment credentials. The coordinator only asked for evidence. Which handoff is best?

  1. Give the worker permission to deploy a patch before reporting evidence.
  2. Allow every tool the coordinator itself can access.
  3. Treat the worker’s role name as sufficient proof of authorization.
  4. Specify a read-only evidence scope and withhold unnecessary execution or deploy privileges.

Explanation

Correct Answer

D:

Delegated expertise does not justify broad side-effect authority.

Incorrect Answers

A:

Production modification is a separate decision requiring authorization.

B:

Parent capabilities need not be replicated to each child.

C:

A role label is not a concrete permission grant.

Question 592

A file manager tool accepts `operation` as optional and defaults to delete if omitted. Agents sometimes omit it while asking for metadata. How should it change?

  1. Hide the operation from the tool schema.
  2. Require an explicit operation enum and use a safe read-only default or reject missing values.
  3. Keep deletion as the silent default for convenience.
  4. Infer deletion intent whenever the user mentions a filename.

Explanation

Correct Answer

B:

Destructive behavior must not be triggered by ambiguous input.

Incorrect Answers

A:

Unknown effects make reliable selection harder.

C:

An omitted parameter could erase files during an inspection request.

D:

Mention of an object is not authorization to destroy it.

Question 593

A tool returns nine successful searches and one permission-denied search in a ten-query request. How should the caller receive the result?

  1. The denied resource content in an error message.
  2. Per-query records with nine completed results, one denied resource and overall partial status.
  3. Ten completed results with the denied query replaced by an empty list.
  4. A total failure that discards all nine valid search results.

Explanation

Correct Answer

B:

Typed item outcomes preserve progress without disclosing denied content.

Incorrect Answers

A:

Authorization failures must not reveal protected data.

C:

That misrepresents permission failure as no matches.

D:

Usable evidence need not be thrown away because one item was denied.

Question 594

A student asks for the conceptual distinction between agent delegation and tool calls. The assistant has several connected workspaces but no user data is needed. What tool choice is best?

  1. Always inspect private workspaces to personalize conceptual explanations.
  2. Require a destructive tool call before any response.
  3. Invent live account findings to demonstrate tool use.
  4. Explain the concepts without accessing connected accounts, citing product documentation only if technical precision requires it.

Explanation

Correct Answer

D:

Available tools should be selected by task need. Unnecessary account access increases exposure and cost.

Incorrect Answers

A:

The user did not request private data retrieval.

B:

Side effects are unrelated to the educational question.

C:

Examples must not be falsely presented as retrieved facts.

Question 595

A previously approved MCP integration now advertises a new bulk-export tool. The analyst only needs the older lookup functionality. Which policy should apply?

  1. Review and explicitly authorize the new capability before exposing it, while retaining the approved lookup scope.
  2. Enable export automatically because lookup was trusted.
  3. Disable monitoring during upgrade to avoid noisy records.
  4. Invoke bulk export to discover whether it is dangerous.

Explanation

Correct Answer

A:

Server updates can broaden authority; past trust does not automatically grant export rights.

Incorrect Answers

B:

A different side effect requires separate scope review.

C:

Audit evidence helps detect inappropriate tool use.

D:

Testing a consequential capability can itself disclose data.

Question 596

A pre-tool hook rejects a request to edit a protected settings file. The agent receives a text string “blocked by policy.” Which interpretation is correct?

  1. Retry with a renamed file path to bypass protection.
  2. Delete all previous source evidence so the agent can try a new plan.
  3. The tool was not executed; report the blocked state and request permitted scope if the task truly needs the edit.
  4. The file edit succeeded because the hook returned text.

Explanation

Correct Answer

C:

A policy hook intercepts the attempted operation before side effects, distinct from an application error.

Incorrect Answers

A:

Circumvention violates the enforced boundary.

B:

A permission denial does not justify erasing context.

D:

Hook output cannot certify a tool that was never run.

Question 597

A research agent reaches a normal end-of-turn after writing a partial summary, but a mandatory citation lookup is still unresolved. What should the host do?

  1. Invent a source URL to fill the missing citation.
  2. Rerun all prior successful tools instead of just the missing lookup.
  3. Keep the task incomplete and either complete the citation step or report the verification gap explicitly.
  4. Treat any end-of-turn as proof the requested research is fully verified.

Explanation

Correct Answer

C:

A model stop condition describes generation, not the satisfaction of every business requirement.

Incorrect Answers

A:

A fabricated reference cannot support the claim.

B:

Unnecessary repetition does not solve the specific gap efficiently.

D:

The outstanding lookup contradicts that conclusion.

Question 598

An architecture coordinator asks a security subagent and a cost subagent to evaluate two deployment regions. Security documents a mandatory data-residency constraint. How should the coordinator decide?

  1. Select the cheapest region and defer compliance review until after deployment.
  2. Average the regions’ costs and locations to invent a compromise region.
  3. Hide the security finding so the cost comparison remains simple.
  4. Exclude noncompliant regions before comparing the remaining feasible cost options.

Explanation

Correct Answer

D:

Constraints define the valid solution set; low price cannot override legal placement requirements.

Incorrect Answers

A:

A deployment decision must satisfy mandatory constraints first.

B:

Neither an average geography nor a blended price guarantees compliance.

C:

Withholding evidence undermines the decision.

Question 599

A reporting agent is authorized to send a confidential file to one named recipient. The workflow later changes to a broader distribution list. What must happen before sending?

  1. Reuse the old receipt because the document itself is unchanged.
  2. Send first and provide a list of recipients afterward.
  3. Let the model choose which additional recipients seem appropriate.
  4. Revalidate approval for the exact updated recipient set and data classification before tool execution.

Explanation

Correct Answer

D:

A prior single-recipient approval cannot authorize broader distribution.

Incorrect Answers

A:

Recipient scope is part of the authorized action.

B:

Retrospective disclosure cannot undo an unauthorized send.

C:

Model preference is not a trusted authorization source.

Question 600

An agent executes a five-step onboarding pipeline. Identity verification and account provisioning succeeded, but equipment ordering failed. Which THREE practices support safe resumption? Select THREE.

  1. Gate final onboarding completion on required steps actually succeeding, not merely returning some output.
  2. Restart all steps under new customer identifiers whenever a later step fails.
  3. Treat ordering failure as proof identity verification was invalid.
  4. Mark every step complete when the pipeline was initially scheduled.
  5. Persist per-step status and stable identifiers for completed external actions.
  6. Retry or escalate only the failed ordering dependency under its original request identity.

Explanation

Correct Answers

A:

The coordinator must distinguish a step being scheduled, producing text, and actually satisfying its business success condition. A directed acyclic dependency graph should block final onboarding status until identity, account, equipment and other required stages have verified success receipts.

E:

Per-step status plus durable external action identifiers allow the resuming agent to distinguish completed provisioning from pending ordering. This prevents reissuing the same account-creation command and supports reconciliation after interrupted sessions.

F:

The failed equipment order can be retried with its stable idempotency key or escalated to an authorized operator while retaining the successful identity/account receipts. Reexecuting only the failed node avoids duplicate side effects and preserves accurate dependency status.

Incorrect Answers

B:

Replaying identity verification or account creation with new customer IDs can produce duplicate external accounts and inconsistent audit trails. A downstream equipment-order failure should not erase prior confirmed commits or change the workflow identity.

C:

Ordering uses a separate provider and may fail despite valid identity checks and successful account provisioning. Treating that failure as proof that earlier steps were invalid would discard good evidence and cause needless rework.

D:

Task submission is a pending operation, not a success acknowledgement. Marking every node complete at scheduling time hides real ordering failures and makes it impossible to retry the failed dependency correctly.
