Question 320 A report generator tool offers summarize_document and extract_table. The assistant chooses summaries when it needs row-level values. What belongs in descriptions? An instruction that summaries always contain exact table cells. The same description for both because they read documents. A claim that all tools automatically validate user requirements. Distinct output contracts that explain summaries versus structured row extraction. Explanation Correct Answer D:The expected result type is decisive when selecting a tool. Incorrect Answers A:A summary need not retain every value. B:Shared domain does not mean equivalent outputs. C:The interface should not promise unimplemented guarantees.
Question 321 A rule applies to all **/migrations/*.sql but misses SQL files inside nested archive folders. Which investigation comes first? Increase the model context window without changing the pattern. Move all SQL files to root automatically. Disable test checks for archive migrations. Inspect the actual paths and revise the glob for required nested levels. Explanation Correct Answer D:Accurate path matching depends on both repository structure and pattern semantics. Incorrect Answers A:Context size cannot make unmatched files load a rule. B:Reorganizing the repository is unnecessary and risky. C:Omitted rules are not a reason to remove validation.
Question 322 An agent runner crashes after a successful API write but before acknowledging it in the session log. What must resumption handle? Reconcile the external operation by idempotency key before replaying pending work. Assume all pending writes succeeded without checking. Assume all unlogged writes failed and repeat them immediately. Delete the database record to reset the scenario. Explanation Correct Answer A:The durable session may lag a completed side effect, so naive replay can duplicate it. Incorrect Answers B:A requested action can also have failed before the crash. C:The first write may have succeeded despite the crash. D:An unrelated destructive reset is not a safe recovery strategy.
Question 323 A coordinating agent merges successful outputs from four workers, but two use incompatible schemas for the same field. What should happen? Drop the mismatched fields without disclosing lost information. Trust the first worker’s schema regardless of business requirements. Normalize through a documented shared schema and reject incompatible values pending correction. Coerce every value to a string and assume meaning is preserved. Explanation Correct Answer C:A common contract prevents semantic type errors during aggregation. Incorrect Answers A:Silent omission changes report coverage. B:Arbitrary preference is not compatibility. D:Type conversion may conceal different units or semantics.
Question 324 A repository reviewer finds four possible bugs, but only one is reproducible with the available test fixture. How should findings be labeled? Separate the confirmed reproducible defect from the other hypotheses and request evidence for each. Suppress the one proven bug because the others are uncertain. Label all four as confirmed because a model produced them. Classify every suspicion as low priority without investigation. Explanation Correct Answer A:Confidence calibration prevents unsupported claims from being promoted to facts. Incorrect Answers B:Unverified claims do not invalidate verified evidence. C:Generation is not verification. D:Some may be material once tested.
Question 325 Claude Code displays “MCP server unavailable” even though the server process is installed. What should be checked first? The user’s keyboard layout. Only the model’s temperature setting. The server registration, launch command or URL, required environment and connectivity. The number of markdown headings in CLAUDE.md. Explanation Correct Answer C:Installed software is not necessarily correctly configured or reachable from the client. Incorrect Answers A:Input layout rarely explains a missing MCP transport. B:Sampling does not establish a transport connection. D:Instruction formatting does not replace server registration.
Question 326 A synthesis worker sees independent analysts each provide mutually inconsistent numbers for the same metric. What should the coordinator require? A reconciliation step that checks definitions, periods, and source provenance before choosing a figure. Suppress the disagreements in the published report. Always trust the first worker to finish. Average all reported values regardless of their units. Explanation Correct Answer A:Superficially conflicting numbers may reflect different denominators or dates. Incorrect Answers B:Unreconciled conflicts should be resolved or disclosed. C:Completion order has no relation to evidence quality. D:Averaging incompatible measures produces a meaningless value.
Question 327 A developer wants a personal preference for verbose explanations across all their Claude Code repositories without imposing it on teammates. Which memory scope fits? A private note embedded in every generated source file. User-level CLAUDE.md preferences outside each shared repository. A committed repository README changed to require all developers to be verbose. A system command that rewrites teammates’ local instructions. Explanation Correct Answer B:Personal settings should follow the user without changing team-wide guidance. Incorrect Answers A:Source code is not an appropriate personal configuration channel. C:That turns a personal preference into shared project policy. D:The preference is not authorized to change other users’ setup.
Question 328 A support analytics classifier labels ordinary shipping delays as fraud because the word “late” appears. What prompt change addresses the cause? Remove examples of legitimate delays. Force all delayed orders into fraud for consistency. Increase the list of trigger words without adding definitions. Provide an explicit fraud definition requiring deception or unauthorized gain indicators. Explanation Correct Answer D:A decision boundary based on actual evidence reduces keyword-driven false positives. Incorrect Answers A:Negative examples help establish the boundary. B:Consistent but incorrect labeling is not precision. C:More keywords can amplify misclassification.
Question 329 An MCP calendar tool accepts user_id but needs an ISO date and timezone to interpret “tomorrow.” Calls fail because those inputs are absent. What schema change is needed? Make all parameters optional and silently default to UTC. Guess timezone from whichever calendar returned first. Require explicit date and timezone fields with clear formats and descriptions. Accept arbitrary free-text strings without any validation. Explanation Correct Answer C:Structured required parameters prevent ambiguous scheduling requests from reaching the backend. Incorrect Answers A:Defaults can book a different local time than the user intended. B:Calendar order does not authorize a temporal interpretation. D:A missing timezone remains ambiguous.
Question 330 A pipeline processes ten independent invoices with a known fixed extract-validate-post sequence. What orchestration is proportionate? Validate only the final aggregate total. A new autonomous planning agent for every extraction field. One giant model call combining all invoices without record IDs. A deterministic per-invoice pipeline with parallel jobs and explicit validation gates. Explanation Correct Answer D:The steps are known and do not require a free-form planner on every invoice. Incorrect Answers A:Each invoice needs field-level checks before posting. B:Extra agents add overhead without resolving a planning ambiguity. C:Mixing cases risks cross-record contamination and makes recovery harder.
