Question #1
Contoso uses Microsoft Dynamics 365 Contact Center with a voice channel. You need to recommend a design for an agent that answers incoming calls, collects the caller's account number and reason for calling, and then hands the call to a human representative who must see the collected details. The solution must minimize development effort. What should you recommend?
Correct answer: D
Explanation
Contact Center supports a Copilot Studio agent as the first responder on a workstream, and context variables carry collected data to the representative at escalation with little custom code. A custom Bot Framework solution adds development effort. A Teams auto attendant bypasses Contact Center routing, and emailed transcripts do not surface details in the representative's session.

Question #2
Contoso has a Microsoft Copilot Studio agent that answers employee questions about HR policies. The agent uses generative answers over a Microsoft SharePoint library of policy documents and has two custom topics for leave requests. Analytics for the last 30 days show the following: Sessions: 14,000 Resolved: 3,500 Escalated: 1,400 Abandoned: 9,100 Most abandoned sessions end immediately after a generative answer, and 38 percent of the thumbs-down feedback is attached to those answers. You need to identify the most likely cause of the abandonment. What should you review first?
Correct answer: D
Explanation
Abandonment is 65 percent (9,100 of 14,000), and the abandoned sessions cluster right after generative answers with negative feedback. Answer quality analytics by knowledge source show whether answers are incomplete, irrelevant or not grounded, and which source causes it. Capacity and escalated-session scores do not explain why users leave after a generative answer.

Question #3
Fabrikam trains a custom classification model to flag fraudulent card transactions. Only 0.5 percent of the transactions in the validation set are fraudulent. Missing a fraudulent transaction costs far more than reviewing a legitimate one. Which metric should you define as the primary validation criterion for the model?
Correct answer: B
Explanation
Recall measures the share of actual fraudulent transactions that the model catches, which matches the cost of missed fraud. Accuracy is misleading with 99.5 percent legitimate transactions because a model that flags nothing scores high. Precision focuses on false alarms, and mean squared error is a regression metric.

Question #4
Contoso uses Microsoft Dynamics 365 Customer Service. Support representatives use Copilot to ask questions about products. Copilot currently answers only from knowledge articles stored in Dataverse. Contoso also keeps 3,000 product manuals in a Microsoft SharePoint site, and representatives want Copilot to answer from those manuals. The solution must minimize development effort. What should you do?
Correct answer: C
Explanation
Copilot in Customer Service can be configured with additional knowledge sources, including SharePoint sites, through administrator settings, which requires no code. A custom agent or fine-tuned model adds development and maintenance work. Converting 3,000 manuals into articles is a large migration that the requirement does not call for.

Question #5
Contoso has a Microsoft Copilot Studio agent that answers questions from a SharePoint knowledge source. The knowledge source is updated every week. You need to recommend a regression test process that runs after each update. The process will use a test set of 200 representative questions that each have an expected answer. The agent's answers are free text, so the wording differs between runs. Which test method should you recommend?
Correct answer: C
Explanation
A compare meaning evaluation judges whether a response conveys the same content as the expected answer, so it tolerates different wording across runs and can be repeated on the full test set. Exact match fails valid answers that are phrased differently. Manual sampling is not repeatable, and a production alert detects problems only after users are affected.

Question #6
Fabrikam uses Microsoft Dynamics 365 Customer Service, Dynamics 365 Field Service, and Dynamics 365 Finance. Copilot summarizes cases in Customer Service, and an agent recommends technician schedules in Field Service. You need to design an end-to-end test scenario for the case-to-invoice process that validates the AI features. The scenario must use only masked data and must not affect production. Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order. Actions: - Complete the work order and verify that the invoice is posted in Finance with the expected amount - Copy production data into a separate sandbox environment for each app - Load masked test data into a single sandbox environment that contains all three apps - Convert the case to a work order and verify that the recommended technician and time slot meet the scheduling rules - Validate the case summary prompt in the Copilot Studio test pane - Create a case from a test customer email and verify that the Copilot case summary matches the email

Correct answer: Load masked test data into a single sandbox environment that contains all three apps; Create a case from a test customer email and verify that the Copilot case summary matches the email; Convert the case to a work order and verify that the recommended technician and time slot meet the scheduling rules; Complete the work order and verify that the invoice is posted in Finance with the expected amount
Explanation
An end-to-end scenario needs one isolated environment where all three apps share masked data, so that hand-offs between the apps can be tested. Separate sandboxes per app break the cross-app flow, and copying production data violates the masking requirement. Each AI output is checked where it is produced, and the Finance invoice check comes last because it depends on every earlier step. Testing a prompt alone in a test pane is a unit test, not an end-to-end test.

Question #7
Fabrikam is starting its first AI initiatives and plans to follow the AI adoption process in the Cloud Adoption Framework for Azure. The first use cases will use Microsoft 365 Copilot. Later use cases will use custom agents built in Microsoft Foundry. For each of the following statements, select Yes if the statement is true. Otherwise, select No. 1. Fabrikam should identify and prioritize AI use cases and define success metrics as part of its AI strategy. 2. Fabrikam should prepare an AI landing zone for the Foundry workloads during the Ready phase. 3. Fabrikam can postpone AI governance policies until it starts to build custom agents, because the first use cases use only Microsoft 365 Copilot. 4. Fabrikam should build custom models in Foundry by default and consider software as a service (SaaS) agents only when a custom model cannot meet a requirement.
Answer each statement, then reveal.
- Fabrikam should identify and prioritize AI use cases and define success metrics as part of its AI strategy.Not answered
- Fabrikam should prepare an AI landing zone for the Foundry workloads during the Ready phase.Not answered
- Fabrikam can postpone AI governance policies until it starts to build custom agents, because the first use cases use only Microsoft 365 Copilot.Not answered
- Fabrikam should build custom models in Foundry by default and consider software as a service (SaaS) agents only when a custom model cannot meet a requirement.Not answered
Correct answer: Yes · Yes · No · No
Explanation
The AI strategy defines prioritized use cases and how success will be measured, and the Ready phase prepares the AI landing zone for platform workloads such as Foundry. Governance applies to Microsoft 365 Copilot as well, because SaaS AI still uses organizational data. The framework recommends starting with SaaS options such as Microsoft 365 Copilot and moving to custom builds only when requirements call for them, so a default of custom models reverses that order.

Question #8
Fabrikam is building a prompt library for sales managers who use Microsoft 365 Copilot to review customer meetings. Before a prompt is published, testers must confirm that it states one clear goal, gives specific context and a source, and sets expectations for the output. Which prompt should the testers approve?
Correct answer: D
Explanation
The approved prompt names a source and specific context (the transcript of the Contoso renewal meeting), one goal (a summary), and expectations for the output (five bullets for a sales director, with action items and owners). The prompt about recent customer meetings has a clear format but no specific meeting or source. The prompt asking what happened has context but no output expectations, and the last prompt bundles several tasks that should be split into separate prompts.

Question #9
Fabrikam has a product support agent in Microsoft Foundry. Tracing is enabled, and about 8,000 conversations are logged each day. Users report that some answers include details that do not appear in the product documentation that the agent retrieves. You need to identify the affected responses across all logged conversations. The solution must minimize manual review effort. What should you do?
Correct answer: C
Explanation
The groundedness evaluator uses a model as a judge to score each response against the retrieved context, so unsupported details can be flagged across every traced conversation without manual review. Expert sampling covers only a fraction of the 8,000 daily conversations and adds manual effort. Latency alerts and content filter annotations measure performance and safety, not whether a response is supported by the documentation.

Question #10
Contoso runs a customer service agent in Microsoft Foundry that calls a model deployment named chat-prod. Users report slow responses during the morning peak. Monitoring data for the peak hour shows the following: Deployment type: Standard Tokens-per-minute (TPM) quota: 300,000 Peak TPM consumed: 296,000 Average prompt tokens per request: 720 Average completion tokens per request: 180 HTTP 429 responses: 14 percent of requests Content filter blocks: 0.1 percent of requests You need to recommend a change that reduces the slow responses. What should you recommend?
Correct answer: B
Explanation
Peak consumption is 296,000 of the 300,000 TPM quota and 14 percent of requests receive HTTP 429, so the deployment is being throttled and needs more capacity. Retry with backoff handles 429 responses more gracefully, but every retried request still waits, so users still see slow responses. Completions average only 180 tokens, so fine-tuning for shorter output saves little, and raising max_tokens would only increase token use.
