Microsoft AB-100 Practice Test 42

Question 410

A plant manager approves a high-risk maintenance action valid for the next 20 minutes. The field agent attempts to execute it two hours later using the same token. What should occur?

Extend the approval indefinitely whenever the agent’s retry counter is nonzero.
Execute first, then refresh the approval timestamp in the agent’s stored narrative.
Treat a read-only work-order view as an equivalent approval for the later execution.
Reject the expired approval and request a new authorization tied to the current maintenance request.

Explanation

Correct Answer

Short-lived approval prevents stale authority being reused after the operational conditions or responsible staff change.

Incorrect Answers

Retries do not prolong delegated authority; execution must respect the actual expiry of the approved window.

Backdating or rewriting the narrative would conceal an unauthorized operation rather than satisfy the prerequisite.

Viewing an approved request does not prove the current caller holds valid time-bound execution authority.

Question 411

An agent proposes changing a supplier’s bank details. Policy requires a requester and a different verifier before any payout can use the new account. What architecture is appropriate?

Record a separate verifier identity and block activation until a different authorized person confirms the bank change.
Allow the proposing agent to fill both requester and verifier fields with the same service identity.
Update the active payout account immediately while the verifier task waits for acceptance.
Accept an attached supplier PDF saying verified without confirming the verifier in the approved identity service.

Explanation

Correct Answer

Segregation of duties must be enforced in the payment master-data system, not inferred from conversation text.

Incorrect Answers

A single actor cannot satisfy a two-person verification policy even when the form has two populated fields.

Activating the changed account before independent verification exposes payments to the very risk the control addresses.

A document supplied during the request cannot itself establish that a distinct authorized verifier approved the change.

Question 412

A compliance reviewer rejects an agent-generated request to release a restricted shipment. At the next scheduled run the agent proposes the same action from cached case notes. What should govern the retry?

Treat the absence of a new reviewer comment as implicit approval.
Persist the rejection as an authoritative workflow state and require a documented new-review trigger before reconsideration.
Clear the rejection whenever a model produces a higher confidence score.
Retry the shipment release under a different agent identity until a tool call succeeds.

Explanation

Correct Answer

A prior denial remains binding until approved conditions justify reopening; the agent cannot evade it by rerunning.

Incorrect Answers

Silence after an explicit denial is not a positive release authorization.

Model confidence does not change the actual review decision or establish new compliance evidence.

Switching identities to bypass a denial undermines authorization and the required actor-level audit trail.

Question 413

A manufacturing assistant combines two raw-material feeds. One expresses chemical quantities in kilograms; the other stores pounds but omits the unit label. What data validation must precede its batch recommendation?

Average the two quantities before identifying the source units.
Convert only the final explanatory text to kilograms while leaving the computation in mixed raw units.
Normalize quantities to a documented canonical unit with verified source units and reject ambiguous records.
Let the model infer that every numeric value is kilograms because the first feed uses that unit.

Explanation

Correct Answer

A numerical match between feeds is unsafe if the physical unit differs by a conversion factor.

Incorrect Answers

Averages across different units are not meaningful and conceal the underlying conversion error.

Display formatting cannot repair a calculation performed on quantities with inconsistent dimensions.

Assuming unlabelled values are kilograms can materially distort the mix and cannot be justified by a neighboring feed.

Question 414

A production scheduling copilot reads a machine-hours table containing negative actual run times and duplicated event IDs. Which TWO independent data gates should be applied before scheduling? (Select TWO.)

Deduplicate events using stable source event identifiers and preserve a correction trace.
Scale all durations by a fixed factor until the annual total matches the budget.
Sort the duplicate events by the operator’s display name and keep every row.
Ask the model to estimate missing time from its preferred response style.
Validate operational duration bounds and quarantine impossible negative run times.

Explanation

Correct Answers

Repeated event IDs would double-count machine time unless the ingestion contract enforces uniqueness.

Physical-duration validity should reject negative machine run intervals rather than treating them as capacity.

Incorrect Answers

A budget target cannot determine actual machine time or correct invalid event-level observations.

Sorting changes the presentation but does not remove duplicated capacity consumption or validate the values.

Generation style cannot establish observed run time and would weaken the source-of-record evidence.

Question 415

A treasury assistant ingests a bank statement where credits are positive and an ERP export where customer refunds appear as negative outflows. Summing both as positive has doubled reported cash. What should be fixed?

Map both feeds to documented debit/credit semantics, reconcile against posted transactions and test refund examples.
Treat every positive-looking number as revenue and disregard transaction type.
Prompt the assistant to explain that cash always rises after customer refunds.
Average the two unreconciled totals and accept the midpoint as the authoritative balance.

Explanation

Correct Answer

Sign conventions are part of source correctness; a grounded cash result requires consistent accounting meaning.

Incorrect Answers

Raw sign alone cannot identify cash inflow across feeds that encode the same event differently.

A confident narrative cannot turn outflows into inflows or repair the underlying normalization rule.

A midpoint between inconsistent calculations need not equal the posted financial ledger.

Question 416

An agent compares warranty records after a product merger. A legacy model code now maps to two different current products; both are found by vector search. What must be resolved?

Apply whichever warranty has the longest term to every ambiguous code.
Use a versioned, effective-date product-code crosswalk and stop the claim when the mapping is ambiguous.
Choose the product description with the closest embedding score without checking effective crosswalk records.
Grant the agent permission to edit both product masters so the models have matching names.

Explanation

Correct Answer

An explicit identity mapping avoids applying the wrong product’s coverage to a legacy identifier.

Incorrect Answers

The longest coverage is not necessarily contracted and can create unauthorized commitments.

Semantic proximity does not establish which successor product legally covers the legacy warranty code.

Rewriting master records to force a match obscures the real conversion history and requires governed ownership.

Question 417

A shipment-monitoring agent receives a delivered event at 14:00, then an old in-transit event arrives at 14:07 with an event timestamp of 11:30. What rule prevents false status regression?

Delete the delivered event as soon as an in-transit record arrives.
Have the model estimate the current status from typical delivery patterns without examining timestamps.
Order state transitions by authoritative event time and permitted transition rules rather than message arrival time.
Treat the most recently received event as the latest shipment state regardless of its occurrence time.

Explanation

Correct Answer

A late-delivered older event cannot reverse a verified delivered state merely because its message arrived later.

Incorrect Answers

Removing the authoritative terminal event destroys evidence instead of resolving event timing.

Typical logistics patterns are not a substitute for the shipment-specific event and transition history.

Network delivery order can differ from business event order, causing a regression to an older status.

Question 418

A catalog agent answers general specifications from a weekly product index but must confirm a product recall before advising safe sale. Which source selection is required?

Use the weekly index as authoritative for all recall decisions because product text changes infrequently.
Replace the recall register with a model prediction of whether products are commonly recalled.
Show the product description without any freshness metadata even when the recall service is unavailable.
Use the weekly index for stable descriptions, but check the current recall register for safety-related recommendations.

Explanation

Correct Answer

Recall state changes can invalidate a sale while a weekly product description remains otherwise accurate.

Incorrect Answers

Stable specifications do not prove that the safety status remains unchanged between catalog refreshes.

Predicted likelihood is not an official active recall notice for the specific model and batch.

Concealing an unavailable safety check can lead users to treat a stale listing as sale-ready.

Question 419

A treasury payment agent calculates a cross-border settlement using a quoted exchange rate that expired at noon. The payment will be committed at 16:00. What should the commit service validate?

Require a rate quote still valid at execution time or obtain and approve a new quote.
Accept the expired quote when the generated summary still contains the approved invoice number.
Use the arithmetic average of the expired quote and an unverified news headline as the replacement rate.
Change the stored quote timestamp to the current time without obtaining a new rate.

Explanation

Correct Answer

Currency execution must respect quote expiry and current accepted amount, not a stale planning estimate.

Incorrect Answers

An invoice identifier does not extend the financial validity window of a market rate quote.

Neither a news headline nor an arbitrary average is an authorized executable exchange-rate quote.

Rewriting metadata does not make the market terms valid and breaks the audit evidence.

Question 420

A support employee is removed from an incident-response group at 09:00; their agent’s cached retrieval results remain available until 10:00. How should the service handle a 09:20 question about restricted incidents?

Ask the employee whether they previously had group membership and proceed if they say yes.
Revalidate current entitlements at retrieval or invalidate the affected cache before returning any protected incident text.
Keep serving cached records until the next scheduled hourly index refresh.
Rely on the model to avoid repeating restricted terms while retaining the same privileged context.

Explanation

Correct Answer

Cached document relevance must not override a permission revocation that already took effect.

Incorrect Answers

Self-reported prior membership does not establish present record-level authorization.

An indexing schedule is not authorization; the employee no longer has rights to the protected incident material.

The protected content has already crossed the access boundary if it enters the model context.
