Microsoft AB-100 Practice Test 1

Question 1

A claims intake team wants an AI agent to resolve routine submissions whose decisions depend on reading inconsistent supporting narratives. Fixed eligibility checks already run deterministically. Which division of responsibility is safest?

Replace all validation rules with a single generative prompt so the policy has fewer components.
Use a classification score as proof that a required legal eligibility test passed.
Keep fixed eligibility rules deterministic and use a grounded agent only for narrative interpretation and escalation.
Permit an agent to auto-override a failed eligibility rule when its justification receives a high confidence score from another model.

Explanation

Correct Answer

Deterministic tests are auditable and stable; agent reasoning adds value only for unstructured evidence, while uncertain cases need review.

Incorrect Answers

A prompt cannot replace enforceable business policy, evidence and human exception handling.

Classification confidence does not demonstrate that independently defined legal conditions were satisfied.

A second model score is not independent legal authorization. The policy rule remains binding even when generated reasoning appears convincing.

Question 2

A distributor plans a forecasting agent, but the demand data includes returns and canceled orders. Business users ask the agent to recommend purchasing quantities. What must the architect establish before relying on its recommendations?

Treat gross order count as net demand because a model can infer all returns automatically.
Accept a forecast whenever its generated explanation cites recent sales, without measuring prediction error against normalized net demand.
Define a reconciled demand measure that excludes canceled orders and validates forecasts against observed outcomes.
Grant the forecasting agent purchase-order privileges before verifying its source data.

Explanation

Correct Answer

Reliable analytics requires a defensible target measure, clean history and evaluation against outcomes before acting.

Incorrect Answers

A model cannot repair a misleading business definition merely by generating text.

Descriptive citations cannot replace reconciled canceled-order and return data or a measured forecasting outcome.

Execution privileges should follow evidence of accuracy and approved authority, not precede them.

Question 3

A manufacturing agent can propose reorder quantities, but a purchase over $50,000 legally requires a procurement manager signature. Which architecture keeps that control enforceable?

Generate a proposed order and hold the transaction behind a separate approval service that checks the threshold.
Allow the tool to approve itself when a manager is unreachable.
Include “obtain approval” in the agent system prompt as the only enforcement mechanism.
Write the order first and ask the model to notify the manager afterward.

Explanation

Correct Answer

The transactional system should verify a real approver before committing regulated purchases, independently of the model output.

Incorrect Answers

An agent cannot substitute its own identity for the required human approver.

Prompts guide behavior but do not provide a tamper-resistant transaction authorization boundary.

Post-hoc notification is not prior authorization and cannot reverse an already binding purchase.

Question 4

A sales assistant provides contradictory account-balance answers from two ERP exports. One export includes entries that were later reversed. What data gate is most appropriate?

Reconcile balances against the authoritative ledger and reject or label unverified source records before grounding.
Answer using whichever export has more rows, regardless of reconciliation status.
Average the two exports without checking whether their accounting definitions match.
Choose the ERP export whose account names most closely match the user’s question, without reconciling balances to the ledger.

Explanation

Correct Answer

Accuracy depends on the business system of record and reversal rules; the retrieval layer must not promote unreconciled balances.

Incorrect Answers

Record count is not evidence that values reflect posted and unreversed transactions.

Averages of contradictory balances can create a third incorrect number.

Matching account descriptions does not prove that balance definitions and accounting periods agree with the authoritative ledger.

Question 5

A regulatory help agent cites a policy from 2024 although a new policy took effect this morning. Which requirement should determine whether its grounding data is usable?

An instruction to answer quickly without checking policy revision dates.
A documented freshness window and effective-date filter that excludes superseded policies.
The semantic similarity of the obsolete document to the user question alone.
Prefer the policy PDF with the latest modification timestamp without checking when each revision became legally effective.

Explanation

Correct Answer

An agent may retrieve text relevant in wording but wrong in time; effectivity and source revision are required constraints.

Incorrect Answers

Faster completion with stale policies increases compliance risk rather than reducing it.

Semantic relevance does not establish that a document is currently binding.

A file modification timestamp can reflect a formatting update or draft and cannot establish the controlling policy effective date.

Question 6

A service agent needs shipment facts from a warehouse feed that goes offline during nightly maintenance. What should the architect specify for the grounding dependency?

Return yesterday’s shipment status as though it were live without displaying its timestamp.
Retry the unavailable feed indefinitely while holding the customer session open.
A source-availability check and a safe “status unavailable” fallback instead of inventing current shipment facts.
Ask the model to reconstruct missing tracking events from typical delivery patterns.

Explanation

Correct Answer

A reliable assistant distinguishes current verified data from unavailable information and gives a controlled retry or escalation path.

Incorrect Answers

A historical status can mislead customers unless clearly timestamped and qualified.

Unbounded retries fail availability objectives and do not guarantee the feed recovers.

Common logistics patterns cannot establish this individual shipment’s events.

Question 7

Finance, support and supply-chain agents all need an approved supplier master, but each currently maintains its own spreadsheet copy. Which data strategy best supports reuse?

Share one administrator account among all agents to simplify access to every supplier field.
Let each agent invent supplier identifiers so integrations need not agree.
Copy supplier rows into each prompt with no update or deletion mechanism.
Publish a governed supplier data product with a stable schema, ownership and access-controlled interfaces.

Explanation

Correct Answer

A governed shared contract reduces conflicting copies while letting consuming agents use permitted fields and controlled updates.

Incorrect Answers

Shared privileged credentials remove least privilege and actor-level traceability.

Invented identifiers break joins and audit consistency between business systems.

Static prompt copies become stale and are difficult to correct or revoke.

Question 8

An internal knowledge assistant uses a common search index for two customers. A user from tenant A asks about a contract that belongs only to tenant B. Which design is required?

Retrieve all indexed contracts, then hide restricted paragraphs only in the final rendered UI.
Rely on a visible customer label in the chat interface instead of a server-side filter.
Ask the model not to quote cross-tenant documents after retrieving them.
Enforce tenant-scoped authorization on retrieval results before the model receives document content.

Explanation

Correct Answer

The search and data access boundary must filter unauthorized documents before they enter model context.

Incorrect Answers

Late hiding cannot undo exposure through prompts, traces or model reasoning.

UI labels have no effect on API-level retrieval authorization.

A prompt prohibition does not stop the model from seeing sensitive content.

Question 9

A customer-service agent quotes a refund policy, but its supporting search result has no source URL, revision ID or effective date. What deficiency should block an authoritative answer?

Confirm citation policy by matching only the visible article heading to the response heading.
Accept the assistant’s citation because the retrieved snippet exactly matches the answer text, without resolving the source or revision.
Count the presence of formatted citations in the answer without validating that their identifiers resolve to a published policy revision.
Missing provenance that links the quoted statement to an approved, current policy source.

Explanation

Correct Answer

Policy advice should be traceable to a verifiable source and effective version so a reviewer can reproduce it.

Incorrect Answers

Matching a heading can establish topical similarity but not which approved refund-policy revision supplied the quoted clause or when it took effect.

Matching quotation text is insufficient: a snippet can be from a superseded or unapproved copy and requires source identity, effective date and reviewable provenance.

Formatted citation markers can appear credible even when their target does not establish source provenance and validity.

Question 10

An AI program combines HR and Finance datasets. The data team cannot decide who approves corrections to shared employee-cost fields. Which organizational control is missing?

A prompt telling users to edit source data when an answer seems unexpected.
A nightly export into an unmanaged spreadsheet accessible to every team.
Assume that using a stronger embedding model eliminates the need to assign a data steward for shared HR and Finance records.
A named data steward and escalation workflow for ownership, quality and authorized updates.

Explanation

Correct Answer

Clear stewardship assigns accountable owners who can resolve conflicting records and approve changes at the system of record.

Incorrect Answers

Ad hoc end-user edits risk corrupting shared records and bypassing review.

An unmanaged copy increases access and reconciliation problems instead of defining ownership.

Better retrieval does not provide organizational authority over quality corrections, access permissions or lawful use of employee data.
