Microsoft AB-100 Practice Test 48

Question 470

An insurer has an approved case-routing agent. A custom alternative may improve unusual claim triage but has not been measured. Which migration approach protects current service?

Switch all customer traffic to the custom agent immediately and retire the known-good rollback path.
Run both agents as independent writers for every claim without a shared case state.
Judge the custom agent solely on its development-team demo without independent case measurements.
Pilot the custom triage for the bounded exception class while preserving the prebuilt primary flow and comparing outcomes.

Explanation

Correct Answer

A narrow trial can establish incremental value without replacing a working platform before acceptance criteria are met.

Incorrect Answers

A full cutover before measured acceptance exposes routine service to unverified failures.

Concurrent uncoordinated action paths risk duplicate updates and contradictory customer communications.

A polished demo cannot establish error, escalation and permission behavior under actual claim conditions.

Question 471

A Copilot Studio agent sends `amount: 8500` to an expense-reimbursement tool without a currency field. The tenant operates in USD and EUR. What must the tool schema enforce?

A typed amount plus an allowed explicit currency code, validated against the user and claim before payment.
Accept the number without currency and assume the user’s display language determines the payment currency.
Let the model choose whichever currency yields the smaller nominal value.
Write the amount as plain text in the transaction log and bypass service-side type validation.

Explanation

Correct Answer

Numerically equal figures can represent materially different obligations, so currency must not be inferred from chat tone.

Incorrect Answers

Interface language is not a financial contract and can differ from the account’s settlement currency.

Choosing a favorable denomination is not an authorized conversion or a valid interpretation of the claim.

Logging an ambiguous value does not prevent the payment tool from committing the wrong monetary amount.

Question 472

A service agent calls a ticket-creation action. The connector times out after the downstream system may have saved the ticket. What action contract prevents duplicate records?

Tell the model to declare success if the retried action response sounds plausible.
Use a stable idempotency key and query the authoritative ticket result before any bounded retry.
Generate a fresh random request ID on every retry and submit identical ticket details.
Assume every timeout means the database definitely rolled back its write.

Explanation

Correct Answer

The caller must distinguish an uncertain acknowledgment from an absent transaction and avoid repeating the create blindly.

Incorrect Answers

Narrative confidence cannot establish durable ticket state in the downstream service.

Changing the identity defeats deduplication and can create several tickets for one user request.

A lost response may occur after a successful commit and does not prove the write failed.

Question 473

A Copilot Studio action can update contacts in a CRM account. A sales representative requests a bulk update covering another representative’s territory. How should the service enforce scope?

Use the connector’s full administrative privileges for every bulk request to avoid partial failures.
Check only the first contact in the batch and assume all later contacts share its owner.
Authorize each target record against the caller’s actual territory permissions before executing any batch change.
Authorize the batch only by checking that the model output is valid JSON.

Explanation

Correct Answer

A valid login does not imply write permission to every contact named in an agent-generated bulk request.

Incorrect Answers

An elevated service identity would bypass record-scope policy and increase unauthorized modification risk.

Mixed ownership across a batch makes first-record authorization insufficient for the remaining requested changes.

Typed syntax is necessary but does not establish the caller’s rights over the requested CRM records.

Question 474

An agent exposes `CheckInventory` and `ReserveInventory`. Users sometimes ask “is stock available?” but the model invokes reservation. What design reduces unintended writes?

Rename both actions to `Inventory` and let the model infer the intended side effect.
Grant every inventory lookup the same mutation permission so either action can execute.
Hide the reservation confirmation after the action completes to avoid confusing the user.
Separate read and mutation contracts with unambiguous action descriptions, explicit confirmation and service-side authorization for reservation.

Explanation

Correct Answer

A query must not have a side effect merely because the model selected a similar-sounding business tool.

Incorrect Answers

Removing action distinction makes accidental write selection more likely rather than clarifying the user’s intent.

A data request does not confer authorization to reserve limited stock for a customer.

Suppressing a notification does not prevent an unintended inventory commitment.

Question 475

A purchase action returns `{status:"pending",orderId:"PO-14"}`. The agent tells the user “order shipped” because it paraphrases pending as completed. What interface control should prevent that?

Use an enumerated status contract and require authoritative fulfillment confirmation before claiming shipment.
Raise generation temperature so the assistant varies how it describes pending results.
Change the local display label from pending to shipped without updating the order service.
Ignore the status field and assume any returned order ID proves dispatch.

Explanation

Correct Answer

Pending order acceptance is not shipment; status values must map to allowed customer-facing statements and state transitions.

Incorrect Answers

Sampling changes wording, not the business meaning of an unfulfilled order status.

UI text cannot establish that goods have left the warehouse or that shipment tracking exists.

An order identifier can exist long before packing, carrier handoff or customer delivery.

Question 476

A Copilot Studio policy agent serves contractors and employees. Both can access published safety guidance, but only employees may read internal incident reports. Which knowledge design is appropriate?

Rely only on a system prompt telling the agent not to reveal employee information.
Connect separately governed sources and enforce the caller’s document permissions before presenting retrieved passages.
Search all knowledge sources under a tenant administrator identity and redact incident titles at the end.
Store every incident report in a public website source so all users can query it consistently.

Explanation

Correct Answer

The same subject matter does not make private employee incident data appropriate for contractor context.

Incorrect Answers

Prompt instructions cannot prevent a privileged connector from returning unauthorized document content.

Late redaction cannot undo exposure through retrieved context or model-generated details.

Making protected reports public is not a legitimate solution to retrieval permissions.

Question 477

A leave-entitlement agent sees a signed regional policy and a newer draft circulated for comment. A user requests the amount of leave available today. Which source rule should control?

Average the days of leave stated in both documents for a compromise answer.
Cite the draft without identifying its provisional status so the answer appears current.
Filter to the approved effective regional policy and exclude the draft until its formal effective date.
Use the draft because the file has the latest modified date.

Explanation

Correct Answer

Current authority comes from publication and effective status, not semantic similarity or a newer draft timestamp.

Incorrect Answers

Employee entitlement is governed by an authorized policy, not by a numerical midpoint between revisions.

An unlabeled draft could mislead employees into relying on terms that have not been approved.

Recent editing does not establish that a proposed policy is legally in effect.

Question 478

A service agent needs warranty repair instructions and a live warranty expiry date for a specific serial number. The manual is indexed weekly; the entitlement service is real time. How should it ground both?

Index one customer’s live expiry date into the public repair manual and use that for every serial number.
Infer warranty expiry from the model’s confidence about product age.
Skip the repair manual and let the live entitlement API invent technical repair instructions.
Retrieve approved manual passages and query the authenticated serial-number entitlement API for current coverage.

Explanation

Correct Answer

Instructional content and customer-specific transactional entitlement have different source, freshness and authorization requirements.

Incorrect Answers

Coverage is serial-specific and should not be copied into a general document accessed by unrelated customers.

Age estimates do not establish contract terms or registered customer purchase dates.

Coverage verification does not supply the approved procedural steps or safety information needed for repair advice.

Question 479

An employee health-benefits agent searches an approved handbook and a popular internal discussion thread with informal suggestions. Which retrieval policy should govern a binding benefit answer?

Use the approved handbook for entitlement claims and label discussions as non-authoritative context when permitted.
Use the discussion reply with the most reactions instead of the handbook.
Treat the latest thread comment as an amendment to the signed benefits policy.
Combine contradictory thread and handbook terms into a newly worded allowance.

Explanation

Correct Answer

High-engagement conversation text is not the published source of the organization’s binding benefits policy.

Incorrect Answers

Popularity can reflect helpful anecdotes, but does not confer formal policy approval.

Only the controlled publication process can create an effective policy change.

An invented compromise may promise benefits that neither legally operative policy nor approval authorizes.

Question 480

A facility compliance agent retrieves a low-quality OCR extract with ambiguous emergency valve numbers. A field engineer asks which valve to close. What should the agent do?

Answer confidently to avoid delaying the engineer, omitting the OCR uncertainty.
Withhold a definitive valve instruction and escalate to a verified maintenance procedure or qualified operator.
Select whichever valve number appears most often in the corrupted OCR extract.
Use the nearest numerically adjacent valve code if the scanned digits are unclear.

Explanation

Correct Answer

A misread equipment identifier is safety-critical, so incomplete source evidence must not become an actionable command.

Incorrect Answers

A rapid unsupported command is not safer than an explicit evidence and verification escalation.

Repeated OCR artifacts can be wrong and cannot establish the actual tagged field equipment.

Proximity of identifiers does not prove the correct isolation point and could create a safety hazard.
