Microsoft AB-100 Practice Test 90

Question 890

An insurance assistant uses one model on Monday and another on Tuesday under an unchanged display alias. An auditor needs to replay Tuesday’s recommendation. What should be captured?

Only the displayed model alias.
The representative’s personal view of which model felt faster.
Only the final recommended outcome.
The resolved model artifact/deployment ID with prompt version, source snapshot and evaluation settings for that run.

Explanation

Correct Answer

Mutable aliases conceal backing-model changes unless actual serving artifacts are recorded.

Incorrect Answers

An alias can point at multiple artifacts over time.

Subjective impressions do not prove exact model identity.

An outcome without input/configuration provenance cannot be independently reconstructed.

Question 891

An agent audit log stores approvals and executed refunds in a database all chatbot makers can edit. Which security architecture corrects this?

Use append-only or tamper-evident logs with scoped writer/read roles and retention controls.
Keep the current editable table because the makers are employees.
Delete refund approvals after the customer receives a message.
Use a model-generated summary instead of transaction event history.

Explanation

Correct Answer

Authors of agent prompts should not be able to rewrite authoritative financial approval evidence.

Incorrect Answers

Internal access does not justify changing historical transaction records.

Premature deletion destroys accountability and dispute evidence.

Natural-language summaries cannot substitute for tamper-evident event records.

Question 892

A data steward changes 500 mislabeled examples, and a custom model is retrained. Operations cannot tell if production uses the corrected data. What must the audit trail link?

The number of examples corrected without dataset identity.
The steward-approved dataset revision, training job, resulting artifact hash and production deployment ID.
Only the new model’s display title.
Only the date when the steward sent an email.

Explanation

Correct Answer

An end-to-end lineage chain proves which corrected labels influenced the served model.

Incorrect Answers

A count cannot prove which records were changed or used for training.

A name does not identify training data or deployment content.

Communication timing cannot establish the actual data and model versions promoted.

Question 893

A service agent recommends rejecting a warranty request, but an authorized reviewer overrides it after finding valid coverage. What should the audit record contain?

Keep only the final customer message as the entire audit.
Let the agent rewrite the reviewer’s identity in the log for consistency.
Original recommendation and sources, reviewer identity, override reason, final decision and linked case outcome.
Delete the model recommendation once a person changes it.

Explanation

Correct Answer

Overrides are necessary governance evidence for correcting model mistakes and improving future evaluation.

Incorrect Answers

A response does not show who changed the decision or on what evidence.

Accountable human decisions require authentic identity, not generated attribution.

Removing history prevents analysis of the original policy or model failure.

Question 894

A purchasing agent drafts a $65,000 supplier order. The spending policy requires a manager approval above $50,000. Which architecture enforces it?

Trust the assistant’s sentence that the manager would probably approve.
Divide the order into two below-threshold payments.
Submit the order and request retrospective approval afterward.
Keep the order pending until a separate authenticated approval service authorizes the exact amount and supplier.

Explanation

Correct Answer

The transaction must be approved before a high-value purchase creates a binding obligation.

Incorrect Answers

Prediction cannot substitute for actual delegated financial authority.

Splitting a single obligation evades rather than satisfies spending policy.

Post-commit review does not meet a prerequisite signature requirement.

Question 895

An authorized finance manager approves a $10,000 payment to supplier A. The agent later changes the bank beneficiary to supplier B before execution. What must happen?

Invalidate or reauthorize the material change and require a verified approval bound to the new beneficiary.
Keep the first approval because the dollar amount is unchanged.
Ask the agent to append “same transaction” to the request.
Execute and inform the manager afterward that the bank changed.

Explanation

Correct Answer

Approval of a transaction tuple cannot silently transfer to a different payee.

Incorrect Answers

Beneficiary identity is a material approval attribute independent of amount.

Generated words cannot extend a manager’s authenticated authorization.

A post-payment notification does not prevent an unauthorized transfer.

Question 896

A payroll agent requests two independent signoffs for bonus changes. One manager approves twice using two browser sessions. What should the system enforce?

Accept the second click whenever it occurs after a short delay.
Distinct authenticated approver identities and separation-of-duties rules bound to the exact bonus request.
Count two sessions as independent human approvals.
Allow the language model to provide the second signature.

Explanation

Correct Answer

Two approval events from the same principal do not satisfy a two-person control.

Incorrect Answers

Time separation does not confer independent authorization.

Session count does not establish distinct authorized people.

Model-generated rationale is not an authenticated manager decision.

Question 897

A finance agent receives approval for a purchase, then pauses when the payment gateway is down. It retries later. What should the retry validate?

Assume approval never expires regardless of business policy.
Create a fresh payment key every time the service is slow.
Approval identity, amount, payee, expiry and current authorization state before the original idempotent payment attempt resumes.
Retry with a new payee if the first account is unavailable.

Explanation

Correct Answer

Delayed execution must still satisfy exactly the transaction the approver authorized.

Incorrect Answers

Authorizations may be time bound or revoked before execution.

Uncoordinated new identifiers can cause duplicate payments after ambiguous timeouts.

An altered beneficiary is not covered by the original payment approval.

Question 898

A spending request is reviewed and rejected by the designated manager. The agent argues that fulfilling the purchase would improve customer satisfaction. What should happen?

Execute because the model supplies stronger reasoning than the manager.
Submit the order with a different request ID to bypass the rejection.
Mark the rejection as a temporary technical outage and retry automatically.
Block the order and record the rejection, allowing a new authorized review only under the formal escalation process.

Explanation

Correct Answer

Business benefit does not empower the agent to overrule a signed financial denial.

Incorrect Answers

Generated persuasion is not a replacement for delegated authority.

New identifiers cannot legitimize an already denied purchase intent.

An explicit policy decision is not a transient connector failure.

Question 899

A customer-service agent receives approval for a $250 goodwill credit, but the customer later asks for $400. What must the workflow enforce?

Obtain a new authorized decision for $400 before committing, because the approved amount changed.
Use the previous approval because both amounts concern the same customer.
Issue $400 and annotate the original approval as approximate.
Split $400 into two $200 credits under the old approval.

Explanation

Correct Answer

The original signoff was scoped to a smaller exact financial obligation.

Incorrect Answers

Identity consistency does not authorize a larger payment.

Changing record labels cannot broaden authenticated approval retroactively.

Multiple transactions can evade the intended value limit and create audit ambiguity.

Question 900

A procurement assistant produces an excellent sourced justification for paying a restricted vendor, but its payment service indicates the requester lacks signoff authority. What is the final action?

Publish “payment completed” because the proposal itself was technically correct.
Respect the authorization denial and route the exact proposed payment to an eligible approver without executing it.
Call a more powerful model to obtain a higher confidence score.
Retry with an administrator connector to bypass the 403.

Explanation

Correct Answer

Well-grounded reasoning can inform the decision but does not confer financial execution permission.

Incorrect Answers

A justified recommendation is not a committed payment receipt.

Confidence cannot alter backend access roles or supplier authorization.

Privilege escalation would invalidate the intended policy boundary.
