1. Use an agent because variable reasoning and tool selection: Select TWO.

Select two. More than one option is correct — every correct one is ticked below.

1. Use an agent because variable reasoning and tool selection are required, with supported APIs for opportunity actions. ✓

   Variable sales situations and tool selection justify an agent, while supported APIs provide controlled transactional integration.
2. Fine-tune the model on historical opportunities so it learns current pricing and bypasses source-refresh management.

   Fine-tuning changes learned behavior but does not guarantee current pricing knowledge or access enforcement.
3. Expose all pricing and opportunity records to simplify cross-system reasoning and reduce permission-related failures.

   Broad exposure violates data-access requirements and creates security risk rather than solving integration complexity.
4. Permit the agent to update opportunities directly whenever its recommendation confidence exceeds a configured threshold.

   Confidence does not replace authorization, transaction validation, or the required manager approval boundary.
5. Ground recommendations in authorized, owner-managed pricing sources with documented refresh responsibility and current metadata. ✓

   Authorized current sources improve grounding while ownership and refresh processes reduce stale pricing recommendations.

Combine agentic reasoning with authorized current data and governed transactional actions.

2. Assign source owners: What should the architect address first?

1. Assign source owners, remove stale duplicates, establish refresh processes, and validate permissions. ✓

   These controls directly address observed cleanliness, timeliness, accuracy, and authorized availability problems.
2. Add more inventory documents to increase coverage before investigating duplicate and obsolete records.

   More poorly governed content can increase conflicting evidence and reduce answer reliability further.
3. Fine-tune the model using historical exception conversations while leaving inventory snapshots and permissions unchanged.

   Model adaptation cannot correct obsolete source content or enforce reliable access boundaries.
4. Replace retrieval with a larger model so reasoning compensates for inconsistent inventory evidence.

   A larger model cannot reliably infer current facts from inaccurate or unauthorized evidence.

Accuracy requires correcting source quality, freshness, ownership, and permissions before changing model behavior.

3. Publish governed APIs with shared metadata: What is the missing prerequisite?

1. Copy every scheduling table into one unrestricted repository for simpler cross-system consumption.

   Unrestricted duplication creates permission risk and may produce stale competing records.
2. Expose only a natural-language summary because downstream AI systems cannot use structured business data.

   Structured governed data and APIs can support downstream AI systems more reliably than summaries alone.
3. Train a scheduling model on historical appointments so future systems need no live data access.

   Historical training does not provide current availability, permissions, or transactional scheduling state.
4. Publish governed APIs with shared metadata, ownership, refresh rules, and permission-aware access. ✓

   Governed interfaces make business data discoverable, current, reusable, and appropriately authorized for other AI systems.

Other AI systems need governed, discoverable, current, permission-aware data interfaces.

4. Begin with a bounded reporting pilot: Select TWO actions that best implement an incremental AI adoption proces

Select two. More than one option is correct — every correct one is ticked below.

1. Prioritize the most engaging assistant experience first, postponing baseline measurement until adoption is established.

   Engagement alone does not establish business value or provide a reliable basis for adoption decisions.
2. Delegate adoption entirely to a central AI center of excellence without assigning department-level data ownership.

   Central enablement helps governance, but departments still need ownership of data and business outcomes.
3. Begin with a bounded reporting pilot, measure representative outcomes, and use feedback to guide subsequent increments. ✓

   An incremental pilot limits exposure while producing evidence for iteration, governance, and broader adoption decisions.
4. Standardize one architecture immediately across departments so every reporting workload follows identical implementation patterns.

   Immediate standardization can ignore differing readiness, business value, and workload-specific integration requirements.
5. Establish a baseline business outcome, identify data and people readiness, and define acceptable risk before selecting pilots. ✓

   CAF-oriented adoption connects measurable value and risk tolerance with readiness across business, data, people, and platform dimensions.

Baseline value and readiness, then learn through a bounded pilot with measured feedback.

5. Answer representative held-out questions with authorized: Which acceptance criterion is best?

1. Index every policy document centrally so auditors can inspect one repository.

   Central indexing may violate document permissions and does not itself validate answer quality.
2. Use pilot feedback and a target conversation-completion rate as release criteria.

   Feedback and completion measure experience but do not demonstrate authorized, current policy retrieval.
3. Answer representative held-out questions with authorized current evidence and traceable sources. ✓

   This tests realistic answer quality, permission honoring, freshness, and evidence traceability for audit review.
4. Use a larger model and require fluent answers across all policy topics.

   Model size and fluency do not establish current evidence, permission compliance, or audit-ready accuracy.

Require held-out accuracy using authorized, current, traceable evidence.

6. Use separate agents only where responsibilities: Select TWO design decisions.

Select two. More than one option is correct — every correct one is ticked below.

1. Allow agents to share complete branch records so handoffs retain maximum context without filtering.

   Complete sharing can violate permissions and expose unnecessary information across operational boundaries.
2. Use one general agent for every task to eliminate handoff failures regardless of workflow differences.

   One agent may simplify topology but can blur responsibilities and authority across distinct operational tasks.
3. Use separate agents only where responsibilities and handoffs are clear, with defined recovery behavior. ✓

   Decomposition is justified when responsibilities and handoffs are explicit; recovery design limits multi-agent failure propagation.
4. Keep schedule-changing actions behind validated tools and explicit human approval boundaries. ✓

   Tool validation and approval boundaries constrain consequential actions beyond relying on prompts or agent intent.
5. Create an additional coordinator agent that can override all branch and schedule permissions during failures.

   An unrestricted coordinator expands authority and conflicts with least-privilege operational risk controls.

Decompose only with explicit responsibilities and recovery; constrain consequential tools with approval.

7. Escalate defined exceptions with captured context: What recovery path should the solution implement?

1. Escalate defined exceptions with captured context, evidence, and resumable case state. ✓

   Targeted escalation preserves work context and enables accountable specialist resolution when automation cannot safely complete the case.
2. Permit approval when the agent's confidence score exceeds a configured threshold, even when evidence is incomplete.

   Confidence does not replace required evidence, sanctions review, or specialist approval for compliance exceptions.
3. Disable automated processing for every supplier submission and require manual review of all risk decisions.

   Universal manual processing removes appropriate routine automation instead of defining targeted exception criteria.
4. Retry the failed action until the supplier record reaches a completed status.

   Retries cannot supply missing ownership evidence or provide the required specialist judgment.

Escalate defined exceptions with preserved evidence and resumable state.

8. Accuracy of answers on representative held-out questions: Select TWO metrics that directly evaluate this outco

Select two. More than one option is correct — every correct one is ticked below.

1. Prompt-token consumption averaged across all conversations without linking usage to resolution outcomes.

   Token consumption informs operational cost, but does not directly measure resolution time or answer trustworthiness.
2. Employee interface clicks per session as the primary indicator of successful knowledge support.

   Clicks may reflect navigation friction or curiosity and do not establish accurate, timely resolution.
3. Accuracy of answers on representative held-out questions using authorized current sources. ✓

   This measures whether faster resolution preserves trustworthy grounded answers under realistic evaluation conditions.
4. Median time from question submission to accepted resolution. ✓

   This directly measures the stated efficiency outcome across completed employee support interactions.
5. Total monthly conversations, regardless of whether employees received correct resolutions.

   Conversation volume indicates activity, not faster resolution or trustworthy answer quality.

Measure resolution speed and grounded answer quality, rather than activity or usage proxies.

9. Route simple lookups through curated retrieval: Which design best balances cost and latency?

1. Route simple lookups through curated retrieval and a lightweight evaluated model, escalating complex cases to a capable model with tools. ✓

   Workload-aware routing addresses the common latency requirement while reserving greater capability for complex, evaluated analysis.
2. Use curated retrieval alone for every question, including questions requiring multistep analysis and tool-supported reasoning.

   Retrieval supplies evidence but does not necessarily perform the required analysis or tool use.
3. Use a lightweight model for every question because a smaller model is presumed sufficiently accurate and less expensive for all workloads.

   A lightweight model may suit common lookups, but its quality and suitability for complex analysis must be demonstrated through evaluation.
4. Use the most capable model for every question, accepting the same latency and cost for simple and complex workloads.

   Uniform use of the most capable model ignores the dominant simple workload and its under-three-second latency requirement.

Segment the workload and evaluate each model-and-grounding path against latency and quality.

10. Use Microsoft 365 Copilot for permitted employee-facing: Select TWO decisions.

Select two. More than one option is correct — every correct one is ticked below.

1. Build a separate agent that duplicates broad Microsoft 365 context and handles all employee requests.

   Duplicating broad context adds governance and synchronization responsibilities without addressing the specialized ownership boundary.
2. Give Microsoft 365 Copilot unrestricted write access so employees can resolve resource conflicts directly.

   Unrestricted writes violate least privilege and bypass the required approval before resource commitments.
3. Use Microsoft 365 Copilot for permitted employee-facing assistance. ✓

   Microsoft 365 Copilot can provide broad employee assistance when users access only permitted organizational context.
4. Use a separately governed planning agent for specialized rules and approved commitment actions. ✓

   A separately owned planning agent can apply specialized rules, validate actions, and enforce approval before commitments.
5. Distribute planning rules across department-owned prompts so each department controls resource decisions.

   Distributed prompt ownership weakens consistency, accountability, evaluation, and controlled change for consequential decisions.

Use Microsoft 365 Copilot for broad assistance and a governed specialist agent for approved planning actions.

11. Create a constrained custom classifier and validate: Select TWO architectural decisions.

Select two. More than one option is correct — every correct one is ticked below.

1. Create a constrained custom classifier and validate its accuracy and latency against representative workload data. ✓

   Recurring labels and a strict latency target justify evaluating a custom classifier for the constrained classification task.
2. Train a custom model to execute fulfillment transactions directly because accurate classifications remove the need for approval.

   Classification accuracy does not authorize transactions; permissions, validation, and human approval remain necessary.
3. Replace classification with retrieval because the exception codes appear in operational documentation.

   Retrieval can provide evidence but does not by itself satisfy the measured low-latency classification requirement.
4. Fine-tune a general model and use it for both classification and actions after testing only explanation quality.

   Explanation quality does not establish classification latency or safe authorization of operational changes.
5. Use a general model with retrieval for grounded explanations while retaining human approval for operational changes. ✓

   Retrieval supports current explanations, while approval preserves the required control over consequential fulfillment actions.

Evaluate a custom classifier for the constrained task and retain grounded explanations plus approval controls.

12. Create versioned prompts with named owners: Which guideline best addresses the evidence?

1. Maintain a shared prompt library with local variants, periodic review, and optional evaluation when teams request it.

   A shared library helps discovery, but local variants and optional evaluation do not ensure comparable controlled releases.
2. Let each team maintain its own prompt version and compare results only after production release.

   Independent production changes prevent controlled comparison and preserve the observed cross-team inconsistency.
3. Create versioned prompts with named owners, controlled reuse, and held-out evaluation before release. ✓

   This approach directly establishes ownership, traceability, comparability, controlled reuse, and evidence-based release decisions.
4. Assign a central owner to approve wording while allowing teams to release untested local copies for urgent cases.

   Central ownership without controlled reuse and pre-release evaluation still permits inconsistent behavior and weak traceability.

Use versioned, owned prompts with controlled reuse and held-out evaluation.
