Master Microsoft AB-620: Copilot Studio AI Agent Solutions Exam

Correct : A, D

A . Use a Microsoft Graph connector to index the partner's travel advisory content. Microsoft 365 Copilot connectors---formerly called Microsoft Graph connectors---index non-Microsoft enterprise content into Microsoft Graph, making it available for semantic knowledge grounding and citations. Microsoft Learn: Copilot connectors

D . Add the internal policy documents as a knowledge source. The SharePoint PDFs and policy documents should be connected as agent knowledge so generative answers can retrieve and summarize the relevant content. This is scalable and avoids manually maintaining document-specific topics. Microsoft Learn: SharePoint knowledge sources

B violates the requirement to avoid manually authored Q&A topics. C could produce ungrounded responses from unapproved public sources and would not satisfy the airline's accuracy, security, or compliance requirements.

Correct : B

Comprehensive and Detailed Explanation From Microsoft AB-620 Study Guide: Removing the generative answers node eliminates the component that searches the configured knowledge sources and produces the grounded topic response. A standalone custom prompt can format or transform supplied input, but it does not automatically inherit the topic's selected knowledge sources or reproduce the node's retrieval behavior. The resulting answer could therefore have the requested executive-summary style while failing the grounding requirement. The correct design retains the generative answers node and applies topic-scoped custom instructions to its response, or captures the grounded output in a variable and sends that content through a carefully configured formatting prompt. General knowledge should remain disabled when the topic must use only approved enterprise sources. Connector security and data policies continue to govern the actual source connections and cannot be replaced by prompt text. The proposed removal is consequently not a valid solution. Validation should inspect the retrieved sources, generated answer, final format, and behavior when no authorized source returns relevant content.

Correct : B, C

B . Configure prompt instructions that include disclaimer text. Centralized prompt instructions apply the required disclaimer and behavioral controls consistently to generative responses. This avoids maintaining duplicate text in individual topics and reduces the risk of inconsistent compliance language. Microsoft confirms that prompt modifications can control response content, format, personality, and what the agent should or should not answer. Microsoft Learn: Prompt modification

C . Use Markdown syntax within response content. The scenario explicitly requires Markdown for formatting and states that HTML is unsupported. Markdown can provide headings, bold text, lists, and other structured presentation while remaining compatible with the target channels.

Options A and E duplicate disclaimer content across topics, creating unnecessary maintenance and inconsistent responses when the disclaimer changes. Option D violates the stated platform requirement because HTML must not be used.

Correct : C

Comprehensive and Detailed 150 to 250 words of Explanation From [Microsoft AB-620 study guide]: Azure AI Search must be configured as the authoritative retrieval source, with ungrounded or general-knowledge responses disabled. In the retrieval-augmented generation process, Copilot Studio first reformulates the user's question, searches the connected vector index, and supplies relevant results to the Microsoft Foundry-hosted model for response generation. Requiring grounding prevents the model from answering solely from its pretrained knowledge when Azure AI Search returns no sufficiently relevant content. In that situation, the agent should return no generated answer and follow its configured fallback or escalation behavior. Selecting a Foundry model alone does not enforce grounding because model selection controls the generation layer, not the retrieval requirement. Citations provide traceability but likewise do not prevent an unsupported answer. Uploading duplicate documents would introduce another knowledge store and undermine Azure AI Search as the controlled enterprise index. The Azure AI Search connection should identify the intended vector index and use semantic ranking where appropriate. Testing should confirm that valid queries return supported answers and citations, while out-of-scope queries produce no ungrounded response.

Correct : A

Comprehensive and Detailed Explanation From Microsoft AB-620 Study Guide: The agent needs a valid authenticated connection to the MCP server before it can discover and invoke the server's published tools. Copilot Studio supports the authentication methods exposed during MCP onboarding, including API key and OAuth 2.0. The choice must match the server: OAuth is appropriate for user-delegated authorization, while an API key is a shared secret mechanism. Publishing does not create credentials or make an unauthenticated server usable. A Power Platform connector used as real-time knowledge would serve a different retrieval pattern and would not replace the MCP tool contract. Generative answers also do not establish MCP connectivity; generative orchestration can select a tool only after that tool is correctly connected and described. The server and individual tools should have clear descriptions, typed inputs, and constrained permissions. Test the connection under the intended identity, confirm that only expected tools are visible, and implement error handling for consent, expired credentials, denied scopes, server unavailability, and invalid tool output.
