Microsoft AB-100 Practice Test 82

Question 810

A model registry alias `current` points to one artifact in test and another in production, but the promotion report lists only the alias. How should provenance be recorded?

Assume matching alias names imply matching model bytes.
Use only the latest deployment timestamp.
Compare output tone to infer that both environments use identical artifacts.
Record immutable model artifact hashes/versions and environment-to-artifact bindings.

Explanation

Correct Answer

Mutable aliases cannot prove that the tested artifact is the one serving real customers.

Incorrect Answers

Environment-local alias pointers can resolve to different models.

Time alone does not establish which artifact was deployed.

Generated wording is not cryptographic or registry evidence of model identity.

Question 811

A fine-tuned invoice model begins returning decimal amounts as strings with currency symbols. The finance connector requires numbers. What promotion safeguard is needed?

Block promotion through typed output-contract tests or revert to the last compatible model artifact.
Ask the Finance API to accept arbitrary strings as amounts.
Remove validation because the model appears accurate in natural language.
Convert every string by deleting punctuation without testing locale.

Explanation

Correct Answer

Model version approval must include compatibility with downstream numeric schema and validation.

Incorrect Answers

Permissive types can cause incorrect accounting and parse ambiguity.

Fluent descriptions cannot guarantee compatible machine-readable output.

Blind normalization can turn 1.250,00 into a materially incorrect amount.

Question 812

A compliance assistant receives a newly tuned model trained on customer conversations. Which TWO controls are needed before putting the artifact into production? (Select TWO.)

Approve because the training loss decreased.
Give the endpoint unrestricted access to all customer records.
Delete the previous known-good model artifact immediately.
Confirm approved training-data use and immutable model/dataset lineage.
Pass a held-out task evaluation including high-severity failure classes and required output schemas.

Explanation

Correct Answers

The release must be auditable to permitted source data and exact training transformations.

Training quality must generalize to critical production cases and downstream contracts.

Incorrect Answers

Training metrics alone do not establish real-world correctness or lawful data use.

Deployment privilege is a separate security boundary and must follow least privilege.

Removing the rollback target eliminates a recovery path before stable adoption.

Question 813

A training dataset contains customer records later flagged for removal under a lawful deletion request. What must the model governance process do?

Ignore the request because model weights are difficult to inspect.
Ask the deployed model not to mention the customer.
Trace affected training artifacts and apply the approved data-deletion, retraining or risk-remediation process with documented evidence.
Only remove the record from the live CRM screen.

Explanation

Correct Answer

Protected data lineage allows owners to assess which derivative artifacts require action after a source revocation.

Incorrect Answers

Operational inconvenience does not remove applicable data lifecycle obligations.

Output instructions cannot prove that training data use and retention comply.

Derivative training datasets and model artifacts may still retain affected information.

Question 814

A new tuned model routes 20% of invoice cases while the old model handles 80%. What canary metric is needed?

Compare raw error counts without accounting for different traffic volume.
Promote based solely on lower average output tokens.
Identify models by output writing style rather than version IDs.
Compare cohort-normalized exact extraction, business corrections, latency and critical-error rates by immutable model version.

Explanation

Correct Answer

Stable cohorts reveal whether the newer artifact improves production decisions without unacceptable failures.

Incorrect Answers

An 80/20 split requires rate or cohort normalization to compare fairly.

Token reduction cannot justify wrong invoice amounts.

Wording cannot prove which serving artifact handled a case.

Question 815

A release changes supplier tax validation in Finance but a Supply Chain purchase-order agent still sends the old field format. What release approach is required?

Coordinate schema-compatible updates and run end-to-end purchasing/invoicing tests before switching production traffic.
Roll out Finance first and ignore purchase-agent errors.
Allow the model to infer missing tax fields from previous invoices.
Disable input validation to keep orders flowing.

Explanation

Correct Answer

Cross-app agents depend on synchronized financial and inventory contracts.

Incorrect Answers

One-sided changes can block purchase posting or misstate tax.

Historical examples cannot replace current required transaction values.

Accepting incompatible data can corrupt legally material accounting records.

Question 816

A Supply Chain agent begins using a new stock valuation calculation, but Finance closing rules still require the old method through month-end. How should release governance handle it?

Average old and new valuations for a compromise.
Use effective-date and period-bound version controls so cross-app valuation stays on the approved accounting basis.
Let the model choose whichever method yields a smaller expense.
Apply the new calculation retroactively without authorization.

Explanation

Correct Answer

Accounting policy timing must be consistent across source inventory events and financial postings.

Incorrect Answers

Blended calculations may match neither authorized accounting policy.

Preference for a favorable amount is not an approved valuation rule.

Uncontrolled restatement can alter closed financial periods.

Question 817

A finance agent release adds automatic journal adjustments. The month-end close process forbids writes after the period lock. Which safeguard must remain after promotion?

Write adjustments before verifying whether the period is locked.
Use an administrator token to bypass the close check.
Enforce the period-open check in the ledger service for every proposed adjustment, with an exception approval path.
Reopen every closed period when the model proposes a correction.

Explanation

Correct Answer

Agent reasoning cannot override authoritative accounting period state.

Incorrect Answers

A post-write audit cannot replace a required posting prerequisite.

Privileged connectors must still respect signed-off accounting controls.

The model has no authority to change financial close governance.

Question 818

A stock allocation agent is replaced while thousands of reservations remain pending. The new version generates new IDs for each request. What migration behavior is required?

Replay all pending reservations with fresh identifiers.
Discard old reservations because the new model is more accurate.
Count any generated “reserved” text as a successful transfer.
Preserve reservation identifiers and state through a controlled cutover, reconciling unfinished jobs before accepting retries.

Explanation

Correct Answer

Pending business commitments cannot be duplicated or forgotten during agent-version changes.

Incorrect Answers

New IDs can double-allocate inventory that was already held.

Current inventory ownership and commitments live in operational systems, not model weights.

Prose cannot prove warehouse state or durable hold ownership.

Question 819

A solution upgrade changes the return workflow: Supply Chain restocks an item, but Finance refund posting can fail. What should release testing assert?

Correct partial-failure state, no duplicate restock, and safe refund retry or compensation linked to the same return.
Treat a restock receipt as proof the customer was refunded.
Create another return whenever refund posting times out.
Hide failed Finance results from the customer service team.

Explanation

Correct Answer

Multiple systems cannot be assumed atomically committed by one agent flow.

Incorrect Answers

Warehouse state is separate from the Finance payment outcome.

Uncoordinated retries may restock and credit the same item twice.

Concealing errors prevents controlled recovery and truthful status reporting.

Question 820

A new invoice agent release introduces a payment-approval action. The rollout team copied a broad test role into production. What must change before promotion?

Ask the model whether the user sounds like a manager.
Use approved finance role mappings and test permitted and denied approval actions with production-like identities.
Allow every Finance viewer to approve because the action is inside the Finance app.
Hide the approval button but leave the endpoint accessible under a global token.

Explanation

Correct Answer

New business capabilities need explicit user-role authorization, not inherited development convenience.

Incorrect Answers

Conversation style cannot authenticate an approver’s delegated role.

Read permission does not imply transaction signoff authority.

Backend access remains exploitable without service-side checks.
