Microsoft AB-100 Practice Test 16

Question 150

An autonomous service agent may issue low-value credits when an outage is independently verified. A customer asks for a credit when telemetry is missing. What should happen?

  1. Treat the customer’s request itself as verified outage telemetry.
  2. Withhold autonomous issuance and escalate for source verification or authorized manual review.
  3. Treat the customer-service agent’s high confidence in its outage classification as enough evidence to issue a credit.
  4. Grant the agent new billing permissions to force a successful transaction.

Explanation

Correct Answer

B:

Delegated actions must satisfy their evidence gates; missing data is not positive proof.

Incorrect Answers

A:

A request is an allegation, not independent system status.

C:

A model confidence score does not replace independent outage telemetry or an authorized eligibility review.

D:

Privilege escalation cannot repair evidence gaps.

Question 151

A prompt-response employee knowledge agent receives a request to change banking details. What response respects its design boundary?

  1. Ask the user to send passwords in the chat for manual processing.
  2. Write the new number into the model system prompt as authoritative state.
  3. Explain the approved change procedure and direct the user to the authenticated transaction workflow.
  4. Generate bank account changes as if it has committed them.

Explanation

Correct Answer

C:

Read-oriented knowledge assistance should not pretend to execute privileged banking updates.

Incorrect Answers

A:

Collecting secrets through chat is unnecessary and risky.

B:

Prompt content is not a secure transaction database.

D:

A generated statement is not a system-of-record mutation.

Question 152

An agent must determine whether a recorded support call contains a refund promise. Which Foundry Tools category is a sensible first processing step?

  1. Use document OCR on call attachments instead of transcribing the actual recorded speech before determining the refund promise.
  2. Ask a text model to invent the call transcript from the caller’s name.
  3. Transcribe the audio accurately, then evaluate the transcript against approved policy with source time references.
  4. Use a prior autogenerated call summary to decide whether a refund was promised, without validating the source recording or speaker timestamps.

Explanation

Correct Answer

C:

The audio modality requires speech processing before reliable text-based evidence review.

Incorrect Answers

A:

OCR of documents cannot establish which words were spoken, by whom and at what timestamp in a call recording.

B:

Invented dialogue is not a recording.

D:

An existing summary may omit or misattribute the promise; the recorded speech must be transcribed and checked against the relevant time span.

Question 153

A developer wants a generative Power Apps page to suggest report filters based on a user request. What should the trusted application validate?

  1. Allowed filter fields, user data permissions and execution limits before applying generated filter specifications.
  2. Allow the model to join hidden payroll tables to improve suggestions.
  3. Treat generated expressions as safe privileged code by default.
  4. Disable app-level validation to reduce response time.

Explanation

Correct Answer

A:

Generated UI suggestions need a safe schema and permission checks before database queries.

Incorrect Answers

B:

Hidden sensitive data remains protected by access policy.

C:

AI output must not be granted arbitrary code execution rights.

D:

Skipping validation can cause data leaks or erroneous queries.

Question 154

An HR agent repeatedly fails to match a requested parental-leave intent. What is the proper Copilot Studio fallback mechanism?

  1. Write a new leave approval record to force topic matching.
  2. Suppress errors and mark the conversation resolved.
  3. Map the parental-leave intent to a superficially related sick-leave topic without verifying applicable entitlement rules.
  4. Route to a configured fallback topic that gathers missing context or offers a governed human handoff.

Explanation

Correct Answer

D:

Fallback should handle unmatched needs honestly rather than fabricate policy or execute actions.

Incorrect Answers

A:

Creating an approval does not solve language-understanding ambiguity.

B:

False completion hides unmet user needs.

C:

Similar terminology does not make the legal policies interchangeable; the proper fallback must preserve the requested entitlement context.

Question 155

A RAG pipeline returns incorrect product versions because the chunks lost their release tags during preprocessing. What must change?

  1. Increase the search index size without restoring metadata.
  2. Preserve product/version metadata and filter by effective release before retrieval-based answers.
  3. Remove all version labels from the remaining source documents.
  4. Ask the model to always answer as though the latest version were installed.

Explanation

Correct Answer

B:

Version-sensitive business advice needs retained source attributes and explicit filtering.

Incorrect Answers

A:

More untagged chunks do not repair missing version scope.

C:

Further metadata deletion worsens the ambiguity.

D:

Prompt assertions cannot identify actual customer releases.

Question 156

A field-service canvas app shows an AI-generated repair recommendation while the device is offline. What architecture should the architect specify?

  1. Hide offline status so the technician trusts the assistant.
  2. Execute server-side purchase actions while the service is disconnected and report success.
  3. Label cached guidance with last-updated time and require an online verification before high-impact repair orders.
  4. Present cached parts availability as guaranteed current inventory.

Explanation

Correct Answer

C:

Offline assistance can be useful, but transactional decisions need honest freshness and connectivity boundaries.

Incorrect Answers

A:

Concealed staleness undermines operational decisions.

B:

A disconnected client cannot confirm remote state changes.

D:

Cached inventory may change before reconnect.

Question 157

An intelligent Power Platform app meets average latency goals but fails under 20 simultaneous approvals. Which review best matches Well-Architected?

  1. Test peak concurrency and use performance-efficiency capacity planning with reliability and security tradeoffs.
  2. Assume average response time guarantees the 95th-percentile target.
  3. Disable request authorization to save time under load.
  4. Measure only UI loading animation speed and not actual end-to-end service processing under concurrent user requests.

Explanation

Correct Answer

A:

High concurrency requires realistic load testing and measured scaling behavior.

Incorrect Answers

B:

An average can hide severe tail latency.

C:

Skipping auth sacrifices correctness and privacy.

D:

A fast animation can mask overloaded connectors or model endpoints; operational capacity needs real latency and error measures.

Question 158

A Copilot Studio bot must interpret “close the case” as an intent but must not close regulated cases autonomously. Which language and action design is appropriate?

  1. Suppress all case-state validation once a category is identified.
  2. Recognize the intent with a bounded classifier and separately check case authorization before the close action.
  3. Treat every “close” message as a direct privileged command.
  4. Let generated confidence authorize closure without reading the case.

Explanation

Correct Answer

B:

Intent recognition is different from permission to execute the requested transaction.

Incorrect Answers

A:

Classification does not eliminate business validation.

C:

Natural language may be ambiguous or malicious.

D:

Confidence cannot replace record policy.

Question 159

An agent flow calls a shipping service that returns 429 throttling. Which operational pattern should it use?

  1. Retry immediately forever at maximum concurrency.
  2. Generate a fabricated tracking number so the case appears complete.
  3. Apply bounded backoff and retry-after guidance with idempotency and a terminal escalation path.
  4. Retry throttled shipping operations using fresh correlation and transaction identifiers after each 429 response.

Explanation

Correct Answer

C:

A safe flow respects service quotas and avoids duplicate side effects while recovering from transient errors.

Incorrect Answers

A:

Aggressive retries compound throttling.

B:

Invented shipment evidence is harmful.

D:

A new business identifier per retry defeats idempotency and trace reconciliation, while the rate limit still needs bounded backoff and retry-after handling.

Question 160

A prompt action returns a JSON object with valid syntax but contains an unsupported refund reason code. What validation is still required?

  1. Use the first free-text value as an approved code.
  2. Ignore schema version mismatches because the parser succeeded.
  3. Assume any syntactically valid JSON is semantically authorized.
  4. Check the enum against current business rules and reject or request correction before updating Finance.

Explanation

Correct Answer

D:

Syntax validation alone does not prove that values belong to permitted business categories.

Incorrect Answers

A:

Free text does not establish an approved enumerated reason.

B:

Version changes can alter the accepted contract.

C:

Valid JSON can still carry invalid or unauthorized values.
