Microsoft AB-100 Practice Test 66

Question 650

A Copilot Studio agent reasons that it should close outstanding invoices to improve quarter-end metrics, but its assigned tools are read-only. What should the architecture enforce?

Dynamically promote read tokens to write tokens when a business justification sounds strong.
Call the read endpoint with a `force_close=true` query flag and assume it mutates state.
Use a coworker’s privileged connector identity to perform invoice closure.
Keep read-only tool scopes immutable at execution and request separate approval for any write capability.

Explanation

Correct Answer

A reasoning plan may propose actions but cannot create new backend permissions from its own objective.

Incorrect Answers

Authorization cannot be issued solely by the model’s generated explanation.

Unsupported side effects violate the declared API contract and cannot be treated as approved.

Credential borrowing bypasses actor accountability and least-privilege controls.

Question 651

A voice agent reads out a long table containing account numbers and disputed charges in a shared office. The user asks for a private written copy. What is the right multimodal routing?

Use an authenticated private text/document channel and stop speaking sensitive table contents aloud.
Continue reading every account number because speech is already active.
Send the table to a public email address detected in background speech.
Summarize charges from memory without validating the original table.

Explanation

Correct Answer

Voice convenience must be balanced against ambient disclosure and the user’s requested confidential delivery.

Incorrect Answers

The surrounding office may overhear private financial details.

Unverified voice input does not authorize transmitting protected content to a new destination.

A channel change does not permit abandoning factual evidence or exact amounts.

Question 652

A Teams agent summarizes project files in SharePoint. A contractor is removed from one site but still receives cached document excerpts in Teams. What must the design fix?

Grant the contractor site-owner status to synchronize Teams and SharePoint access.
Apply current SharePoint permissions at retrieval time and invalidate stale access-scoped caches.
Leave the cached excerpts and hide their SharePoint URLs.
Instruct the model to avoid naming the removed contractor.

Explanation

Correct Answer

Teams membership alone cannot preserve revoked SharePoint document rights; both layers must be respected.

Incorrect Answers

Expanding privileges is the opposite of honoring an access revocation.

The text itself can disclose restricted project facts without a clickable link.

Name suppression does not revoke permission to read the confidential documents.

Question 653

Two departments have Teams channels called “Operations.” A channel agent is asked to summarize action items. Which context binding prevents cross-department leakage?

Use the channel name only and trust the answer generator to infer context.
Combine all Operations channels into one shared unrestricted summary.
Bind retrieval to the authenticated tenant, team and channel IDs, then enforce each user’s underlying content access.
Choose the first channel returned from the global search index.

Explanation

Correct Answer

Channel display names are not unique security identities and cannot select a safe document scope.

Incorrect Answers

Language similarity is insufficient to distinguish two access-controlled channels.

A global aggregate bypasses the distinct audience and permission boundaries.

Retrieval order may select an unrelated department and leak restricted tasks.

Question 654

A department creates a SharePoint FAQ agent but the library includes approved guidance and drafts tagged “Pending Legal.” What publication rule is necessary?

Prefer drafts when they have more recently edited filenames.
Use all documents equally and ask the model to mention draft status afterward.
Remove approval metadata from the index to improve search relevance.
Index only approved current revisions for authoritative answers, retaining draft visibility only where explicitly permitted.

Explanation

Correct Answer

Publication state and revision lineage must constrain grounding before launch.

Incorrect Answers

File recency does not establish legal approval or effective policy.

Grounding on unapproved clauses can still contaminate a supposedly authoritative answer.

Deleting governance metadata prevents filtering and reproducible citation.

Question 655

A Teams meeting recap agent extracts action items and suggests creating Jira-style work tasks. Attendees asked only for a summary. How should the action boundary be designed?

Publish the summary and proposed tasks, then require explicit authorized confirmation before external task creation.
Automatically create tasks for everyone mentioned in meeting speech.
Declare every suggestion completed as soon as the model writes the recap.
Use a global service account to assign tasks without each attendee’s consent.

Explanation

Correct Answer

Extracting an action item does not itself grant permission to create assignments in another system.

Incorrect Answers

Names in a transcript do not prove assignee identity, acceptance or system permission.

A narrative summary cannot prove work-item creation or actual work completion.

Overbroad identity masks responsibility and can impose unintended obligations.

Question 656

A compliance agent summarizes Teams conversations and SharePoint retention records. It proposes to copy every message into its own permanent index. What architecture principle should govern ingestion?

Grant read access to all employees because the source is an organization-owned site.
Preserve source-specific retention, deletion, and access rules with documented data lifecycle controls.
Save every message forever because embeddings are not personal data.
Ignore a SharePoint file deletion if the same text is used in a chat answer.

Explanation

Correct Answer

An agent index is a derivative information store and must not silently override original retention obligations.

Incorrect Answers

Organizational ownership does not remove per-site and per-document permissions.

Embeddings and linked text can still contain regulated or identifiable information.

Derivative caches need appropriate deletion/expiration propagation and permission checks.

Question 657

A Supply Chain Management purchase agent selects vendor code A-418, while the Finance ledger uses a migrated ID V-9418. What integration gate is required?

Create a new Finance vendor every time the code differs.
Permit the agent to rewrite both systems’ IDs independently.
Validate a governed vendor identity crosswalk before creating any payable or purchase order.
Choose the vendor with the closest display name in Finance.

Explanation

Correct Answer

The business transaction needs one reconciled supplier identity across inventory and accounts payable.

Incorrect Answers

Blind creation produces duplicates and can direct payments to an unintended counterparty.

Uncontrolled changes undermine master-data ownership and other cross-app references.

Similar names may denote different legal entities and cannot establish an audited match.

Question 658

An agent posts a purchase order to Supply Chain Management, then receives a timeout when initiating the related Finance commitment. Which workflow response is sound?

Replay the full purchase and commitment with fresh IDs.
Mark both operations complete because the model generated an order summary.
Delete the purchase order without verifying approvals or downstream receipts.
Query both systems using the transaction correlation ID and resume only the uncommitted step.

Explanation

Correct Answer

Cross-app transactions can be partially complete despite an HTTP timeout; reconcile before another write.

Incorrect Answers

Restarting creates duplicate orders or encumbrances if the first step succeeded.

Generated text cannot prove acceptance by the Finance service.

Compensation must be scoped and permitted based on actual committed state.

Question 659

A supply planning agent predicts demand and asks to reserve 3,000 units, but the live warehouse reports only 1,900 available. Which system should decide the reservation quantity?

The authoritative availability and reservation service, with the forecast retained as a proposal.
Use predicted demand as the stock count because it is closer to future sales.
Allow the agent to mark unavailable units as reserved without stock checks.
Increase the model context window until it outputs 3,000 as an approved quantity.

Explanation

Correct Answer

A forecast is predictive advice; committing inventory requires a verified current stock and allocation rule.

Incorrect Answers

Expected sales and physically available inventory represent different business quantities.

Over-reservation risks conflicting commitments and fulfillment failure.

Longer context cannot create real stock or override allocation authority.

Question 660

A Supply Chain Management agent proposes scrapping damaged stock. The Finance policy requires a write-off approval if value exceeds $20,000. What should the integration implement?

Scrap first and request a manager signature after the financial posting.
Calculate value from authoritative valuation and block the write-off until an authenticated Finance approver signs off.
Use the model’s visual damage estimate alone as the accounting amount.
Approve automatically because warehouse staff have already marked the goods damaged.

Explanation

Correct Answer

The stock-management step and accounting consequence need a shared enforceable financial threshold.

Incorrect Answers

Post-hoc approval cannot satisfy a prerequisite to committing the loss.

Estimated appearance is not a reconciled inventory valuation.

Condition classification does not replace the required financial authority.
