Microsoft AB-100 Practice Test 9

Question 80

Dynamics 365 Sales and Supply Chain Management have conflicting product codes after a merger. A cross-app purchasing agent fails to reconcile stock. What should the solution strategy prioritize?

Choose a newer language model but leave the code mapping unresolved.
Grant both agents permission to rewrite the code catalog independently.
Use free-text fuzzy name matching as the sole reconciliation mechanism.
A canonical product identity mapping with authoritative ownership and integration checks.

Explanation

Correct Answer

Reliable cross-app decisions depend on stable keys and governed transformations.

Incorrect Answers

Model upgrades cannot fix business identifier mismatches.

Independent rewrites create competing source-of-truth records.

Fuzzy names can collide across units and product variants.

Question 81

A returns agent generated an accurate refund rationale, but the finance API rejects the action because the caller lacks approval rights. What should happen?

Retry with the agent service’s global administrator account.
Honor the rejection and route the case to a verified authorized approver.
Alter the request metadata to impersonate the finance manager.
Remove the approval tool and mark the refund completed in chat.

Explanation

Correct Answer

A justified recommendation is not permission to execute; failure should produce a controlled approval handoff.

Incorrect Answers

Privilege escalation defeats the finance boundary.

Impersonation invalidates user and audit accountability.

A chat message cannot substitute for a committed financial transaction.

Question 82

A regulated business needs an AI adoption roadmap across countries with uneven cloud readiness. What first readiness artifact helps avoid uncontrolled production rollout?

A phased deployment matrix of data residency, identity, model access and local operating ownership.
A model shopping list with no governance or cost baselines.
A directive to ignore regional privacy rules until after launch.
A single production tenant shared across countries without access rules.

Explanation

Correct Answer

Roadmap readiness includes secure landing zones and local constraints, not just platform choice.

Incorrect Answers

Model selection cannot replace readiness analysis.

Deferring binding compliance undermines feasibility.

A single broad tenant may violate local data boundaries.

Question 83

An AI business architect is ranking a contact-center virtual agent against an agentic invoice reconciliation process. What KPI comparison is essential?

Prioritize whichever agent wins a prototype user-satisfaction survey without comparing resolution cost and exception rates.
A rule that autonomous agents always outperform assistive agents.
Compare cost per model call across the two pilots while excluding case-resolution, invoice exception and human-handoff cost.
Cost per correctly resolved task, escalation rates and downstream exception costs for each process.

Explanation

Correct Answer

Risk-adjusted value must compare achieved business results and operational workload.

Incorrect Answers

Presentation preference is only an adoption signal and cannot replace process-specific financial outcome analysis.

Autonomy can increase risk when tasks need approval.

Low inference cost is not the same as low correctly resolved-task cost; downstream rework and escalations affect economic performance.

Question 84

A project sponsor says an agentic-first strategy means every step must be autonomous. What interpretation is more accurate?

Remove all workflow conditions so the model may choose policy.
Give one conversational agent all ERP permissions to minimize handoffs.
Treat human approval as proof that an agentic-first design failed.
Design agent-driven workflows where helpful, while retaining deterministic rules and human control for high-impact actions.

Explanation

Correct Answer

Agentic-first describes an architectural approach, not a mandate to bypass controls or manual accountability.

Incorrect Answers

Business policy should not become ungoverned model text.

Excess permissions expand failure blast radius.

Human approval can be an intentional safeguard in agentic systems.

Question 85

A multi-agent supply chain workflow has planner and transporter agents with separate account permissions. How should they exchange shipment requests?

Share the planner’s administrator secret with all downstream agents.
Assume an agent’s message automatically authenticates the business request.
Pass a minimal typed request with correlation ID and verify the receiver’s permissions before execution.
Copy the entire customer database into every handoff prompt.

Explanation

Correct Answer

Structured handoff and least privilege support safe inter-agent orchestration and recovery.

Incorrect Answers

Secret sharing removes role separation.

Agent-to-agent messages still need an authenticated authorization boundary.

Broad context creates unnecessary privacy exposure.

Question 86

A service manager considers replacing a built-in Contact Center agent with a bespoke orchestration platform. What evidence supports a buy-versus-build decision?

Choose custom work simply because the prototype has more lines of code.
Assume built-in functionality cannot be extended before testing supported capabilities.
Ignore service continuity during migration because both use AI.
Document capability gaps, recurring support cost, integration limits and risk of migration.

Explanation

Correct Answer

A supported prebuilt baseline should be compared with measurable customization value and total lifecycle cost.

Incorrect Answers

Code volume is not an outcome metric.

Extensions may meet requirements with less complexity.

Customer-contact availability must be preserved across cutover.

Question 87

A Copilot Studio order action receives a model-generated address that is missing a required postal code. Which tool behavior supports business correctness?

Execute the tool anyway and rely on the shipping provider to guess.
Store the missing field as “approved” to pass schema validation.
Let the model fabricate a postal code from the city name.
Reject invalid structured input and request correction before calling shipping services.

Explanation

Correct Answer

Typed required fields and actionable validation errors avoid corrupted downstream transactions.

Incorrect Answers

Blind execution shifts preventable errors downstream.

Sentinel strings do not constitute a valid postal code.

Guessing addresses can misdirect deliveries.

Question 88

A knowledge agent uses both tenant-protected SharePoint files and public product documentation. A worker asks about an internal financial report. How should the retrieval plan choose sources?

Index all tenant documents with globally accessible search keys.
Use public pages to infer missing private financial numbers.
Use authorized internal content for that caller, retain source provenance and fall back only to appropriate public information.
Cite unrelated public product docs as evidence of internal reporting results.

Explanation

Correct Answer

Grounding requires permission-aware retrieval matched to the requested business facts.

Incorrect Answers

Global search keys bypass entitlement filtering.

Public sources cannot establish private financial results.

A citation to irrelevant content does not support an answer.

Question 89

An enterprise wants to extend existing Microsoft 365 Copilot with a governed ticket-system agent instead of launching a new portal. Select TWO requirements that support the extension safely.

Demonstrate a supported extension integrated into Microsoft 365 workload and sign-in context.
Verify the extension applies each requesting user’s permission scope to ticket retrieval and tool actions.
Grant the extension a single all-tenant administrator identity for every user request.
Move all conversations to an unauthenticated external site for convenience.
Accept parameter count as sufficient proof of user adoption and access safety.

Explanation

Correct Answers

A supported extension leverages existing work surfaces rather than duplicating interfaces.

End-to-end authorization is necessary for records accessed through the agent.

Incorrect Answers

Global credentials bypass per-user permissions and audit attribution.

An unauthenticated portal creates an avoidable identity boundary.

Model size does not validate security, compatibility or actual user outcomes.

Question 90

A tuned custom classifier improves invoice routing accuracy slightly but triples support and monitoring cost. How should the architect decide whether to use it?

Compare the measured incremental business benefit against full model lifecycle cost and risk.
Use only development training loss rather than held-out business outcomes.
Ignore data monitoring because tuning happened once.
Assume any accuracy improvement justifies unlimited cost.

Explanation

Correct Answer

Custom-model economics depend on real error reductions, maintenance and retraining burden.

Incorrect Answers

Training fit is not proof of deployment benefit.

Model performance can change as invoices evolve.

Marginal gains may not justify large ongoing costs.
