Exam Overview
The Microsoft Certified: AI Agent Builder Associate (Exam AB-620) validates the ability to design, build, extend, and integrate custom agents for enterprise-grade solutions using Microsoft Copilot Studio, Azure AI Foundry, and the broader Microsoft Power Platform ecosystem. The certification covers a wide range of advanced capabilities including multi-agent orchestration via the Agent2Agent (A2A) protocol, Model Context Protocol (MCP) server integration, retrieval-augmented generation (RAG), enterprise knowledge source connectivity (ServiceNow, SAP, Azure AI Search), computer-using agents, and Application Lifecycle Management (ALM) for agent solutions.
Currently in beta as of spring 2026 and scheduled for general availability in June 2026, this certification is positioned at the intermediate (Associate) level and reflects Microsoft's strategic investment in agentic AI across its Copilot, Power Platform, and Azure product lines. Candidates who earn this credential demonstrate proficiency across the full agent development lifecycle—from planning identity and governance strategies to deploying and monitoring production-grade agents with Application Insights.
Who Should Take This Exam
This certification is designed for professional developers and advanced builders who create scalable AI agent solutions for organizations or enterprise customers. Target roles include IT application developers, consultants, and independent software vendor (ISV) partners who build custom agents as part of their professional practice. Candidates typically work alongside Microsoft 365 administrators, Power Platform administrators, Copilot Studio architects, and Foundry administrators.
Ideal candidates have hands-on experience configuring agents in Microsoft Copilot Studio—including basic knowledge sources, instructions, tools, and topics—and are comfortable working with REST APIs, custom connectors, Power Fx, Microsoft Dataverse, and adaptive cards. Those building solutions that span Microsoft Fabric, Azure AI Foundry, and enterprise systems like SAP or ServiceNow will find this certification directly aligned with their work.
Prerequisites
There are no formal prerequisites required to sit for Exam AB-620, but Microsoft recommends substantial hands-on experience before attempting the exam. Candidates should have working familiarity with Microsoft Copilot Studio, Power Fx, Microsoft Dataverse, Microsoft Power Platform environments and components, Microsoft 365 Copilot, Azure AI Foundry (Microsoft Foundry), and adaptive cards.
Intermediate-level knowledge of generative AI concepts is expected, including large language model orchestration, retrieval-augmented generation (RAG), prompt engineering, the Model Context Protocol (MCP), and the Agent2Agent (A2A) protocol. Practical experience with REST APIs, integration patterns, and enterprise connectivity is also strongly recommended. Candidates newer to Copilot Studio should complete foundational learning paths on Microsoft Learn before pursuing this associate-level credential.
Exam Format
Exam AB-620 is a proctored assessment delivered through Pearson VUE, available in English. Candidates have 120 minutes to complete the exam, which may include interactive components in addition to traditional question types. A score of 700 out of 1000 is required to pass. As with all Microsoft certification exams, the scoring scale is not linear—results reflect a scaled score that accounts for question difficulty.
Because the exam is currently in beta (as of May 2026), scores are not released immediately; Microsoft gathers data on question quality before publishing results for beta candidates. The exam covers three assessed domains with published weighting: Plan and configure agent solutions (30–35%), Integrate and extend agents in Copilot Studio (40–45%), and Test and manage agents (20–25%). An exam sandbox is available at aka.ms/examdemo to preview the interface and question interaction style before exam day. The Practice Assessment is not yet available but is typically released within 8 weeks of general availability.
Skills Measured
- 1.Plan and Configure Agent Solutions (30–35%): Covers planning integration with enterprise systems, designing identity and security strategies, planning deployment channels, evaluating responsible AI and governance considerations, creating agent flows in Copilot Studio (including human-in-the-loop flows), configuring actions and connectors, implementing error handling, managing topics and variables, configuring adaptive cards, and designing agents for internal or external audiences.
- 2.Integrate and Extend Agents in Copilot Studio (40–45%): Covers connecting agents to enterprise knowledge sources (Copilot connectors, Power Platform connectors, Azure AI Search), configuring and monitoring computer-use agents, adding MCP tools and REST APIs, building multi-agent solutions using the A2A protocol, integrating Azure AI Foundry agents and Microsoft Fabric data agents, configuring generative answers with Azure AI Search and Foundry, using custom prompts with the Foundry model catalog, and monitoring agents via Application Insights.
- 3.Test and Manage Agents (20–25%): Covers creating test sets, selecting evaluation methods, reviewing test results, implementing Application Lifecycle Management (ALM) for agents in Copilot Studio, creating and managing Power Platform solutions, working with environment variables, and extending Microsoft Power Platform Pipelines for agent deployment.
Study Tips
- Use the official AB-620 Study Guide on Microsoft Learn (aka.ms/AB620-StudyGuide) as your primary study roadmap—it lists every assessed sub-skill with bullet-point detail, so you can track gaps systematically rather than studying broadly.
- Complete the self-paced learning paths on Microsoft Learn for Microsoft Copilot Studio, Power Platform, and Azure AI Foundry. Focus especially on modules covering multi-agent orchestration, MCP server integration, and ALM pipelines, as these topics appear in the heaviest-weighted domain.
- Get hands-on in a Copilot Studio trial environment: build at least one end-to-end agent that uses Azure AI Search for RAG, a custom connector or REST API tool, and an agent flow with error handling. The exam includes interactive components, so procedural familiarity is critical.
- Study the Agent2Agent (A2A) protocol and Model Context Protocol (MCP) from Microsoft's official documentation—these are emerging standards that appear explicitly in the exam objectives and may not be covered well in third-party study materials.
- Use the Exam Sandbox (go.microsoft.com/fwlink/?linkid=2226877) to familiarize yourself with the exam interface and interactive question formats before test day, since the interactive components can be time-consuming if encountered for the first time during the actual exam.
- Review Microsoft Copilot Studio documentation for ALM topics—specifically creating solutions, using environment variables, and configuring Power Platform Pipelines. ALM is its own sub-domain under Test and Manage Agents (20–25%) and is often underrepresented in general AI study materials.
- Follow the Microsoft Power Platform Community Forum and the Microsoft 365 Copilot Community Hub for the latest feature updates. The exam may include questions on Preview features that are commonly used, so staying current with Copilot Studio release notes is important.

Preview — answers shown1. The platform engineering team at Contoso Retail wants to expose their Azure AI Search knowledge base as a reusable tool that multiple Microsoft Foundry agents can invoke using a standardized protocol. The team wants to ensure the tools are versioned and can be managed centrally without reconfiguring each agent separately. Which architectural approach correctly describes how MCP tools should be packaged and delivered to meet these requirements? (Select one!)
APublish MCP tools as unmanaged Power Platform solutions and share them across environments using solution export and import
BDeploy each MCP tool as a standalone Azure Logic App and configure agents to invoke the Logic Apps individually via HTTP actions
CRegister each MCP tool as a separate REST endpoint in Azure API Center without versioning, and reference each endpoint directly in individual agent configurations
DPackage MCP tools into a Toolbox—a versioned, reusable server-side collection hosted by Foundry or a remote server endpoint—allowing multiple agents to consume the same tool definitions
Explanation
MCP tools in Microsoft Foundry are designed to be packaged into a Toolbox — versioned, reusable server-side collections that can be hosted and managed centrally by Foundry or a remote server endpoint. This pattern enables multiple agents to reference the same tool definitions without duplication or per-agent reconfiguration, and supports versioning for controlled change management. Registering individual REST endpoints in Azure API Center without versioning lacks the packaging, versioning, and reuse benefits of the Toolbox model. Azure Logic Apps are workflow automation services and are not a native MCP tool hosting mechanism. Power Platform unmanaged solutions are intended for Power Platform component packaging, not MCP tool distribution, and do not provide the versioning or centralized management capabilities required.
2. Coho Winery has deployed a Copilot Studio agent for their customer service operations team. The operations manager needs a monitoring solution that supports custom telemetry queries, proactive alerting when error rates spike, and retention of agent performance data for at least 18 months to satisfy internal compliance requirements. Which monitoring configuration should the team implement? (Select one!)
AEnable the built-in Copilot Studio analytics dashboard and increase the report retention window to 18 months in the tenant settings
BConnect Microsoft Purview audit log policies to capture agent conversation events with an 18-month retention policy
CExport agent conversation transcripts to Azure Blob Storage and query them with an Azure Data Explorer cluster
DConfigure Azure Application Insights integration and set the data retention period to 730 days
Explanation
Azure Application Insights is the designated telemetry and monitoring integration for Copilot Studio agents. It supports custom KQL-based queries against raw telemetry, configurable alert rules for proactive error spike detection, and data retention configurable up to 730 days—which exceeds the 18-month compliance requirement of approximately 548 days. The default Application Insights retention is 90 days, so explicitly configuring 730 days is required to meet the retention mandate. The built-in Copilot Studio analytics dashboard provides operational summaries with a 90-day default retention and does not support custom telemetry queries, custom alerts, or extended retention periods. Microsoft Purview audit logs capture governance and data access events rather than agent performance telemetry and are not designed for custom performance query analysis. Exporting transcripts to Blob Storage requires a custom data pipeline and lacks the native alerting, KQL querying, and analytics features that Application Insights provides out of the box.
3. The customer experience team at Coho Financial Group is deploying a Copilot Studio agent for mortgage application inquiries. Financial regulations require human oversight for complex or potentially high-impact decisions, and the agent must be capable of transferring conversations to licensed mortgage advisors when necessary. The team needs to implement compliant human-in-the-loop patterns. Which two configurations should the team implement to meet these requirements? (Select two!)
Multiple correct answersAConfigure the agent to automatically end the conversation and display a static error message whenever a query falls outside the agent's knowledge scope
BImplement the Escalate system topic to route sensitive or high-stakes conversations to a live human agent through Dynamics 365 Omnichannel, passing context variables such as conversation summary and user information
CSet the generative AI safety settings to maximum autonomy to ensure the agent attempts to answer all complex mortgage questions without restriction
DConfigure fallback topics to handle unrecognized inputs and trigger live agent escalation when the agent's confidence level is insufficient to safely respond
EDisable content moderation settings to prevent legitimate mortgage questions from being incorrectly filtered by safety policies
Explanation
Implementing the Escalate system topic with Dynamics 365 Omnichannel integration and configuring fallback topics for low-confidence scenarios are the correct human-in-the-loop patterns for a regulated financial services deployment. The Escalate system topic provides a native Copilot Studio mechanism to transfer conversations to live agents while forwarding context variables including conversation summary and user information, ensuring the human advisor has full context at handoff. Fallback topics intercept unrecognized inputs and can be configured to trigger escalation when the agent cannot confidently handle a query, preventing high-stakes mortgage decisions from being left to an uncertain AI response. Automatically ending conversations abandons users without resolution and does not satisfy the human oversight regulatory requirement. Setting the generative AI to maximum autonomy increases hallucination risk and regulatory non-compliance exposure for complex financial decisions. Disabling content moderation removes an important safeguard layer and contradicts responsible AI and regulatory compliance requirements in financial services.
4. The network security team at Fabrikam Manufacturing is deploying an on-premises data gateway to enable their Copilot Studio agent to query an on-premises SAP ERP system. The security team needs to know which firewall rules to configure on the gateway server. Which statement correctly describes the network port requirements for the on-premises data gateway? (Select one!)
AOpen inbound TCP ports 5671 and 5672 to allow Azure Service Bus to push data directly to the gateway server
BOpen outbound TCP port 443 and outbound TCP ports 5671 and 5672 to allow the gateway to communicate with Azure Service Bus
COpen inbound TCP port 443 and TCP port 1433 to allow Azure cloud services to initiate connections to the gateway server
DOpen both inbound and outbound TCP port 443 for bidirectional HTTPS communication between the gateway and Azure
Explanation
The on-premises data gateway communicates with Azure using an outbound Azure Service Bus relay connection, which requires outbound TCP port 443 for HTTPS and outbound TCP ports 5671 and 5672 for the AMQP protocol used by Azure Service Bus. Critically, no inbound firewall ports are required because all communication is initiated outbound from the gateway to Azure. This outbound-only design means the gateway can be deployed behind a standard corporate firewall without requiring special inbound rules or DMZ placement. Opening inbound ports would be both incorrect and unnecessary, as Azure never initiates a direct inbound connection to the gateway server. Configuring bidirectional port 443 without the AMQP ports would leave the Service Bus relay connection non-functional.
5. Wide World Importers has built an internal Copilot Studio agent authenticated with Microsoft Entra ID for their operations staff. The agent will be deployed across three surfaces: Microsoft Teams for frontline workers, a custom internal portal built as a Power Apps canvas app, and a department SharePoint site where the agent is embedded using the website channel via a Direct Line iframe. The security team requires that employees experience zero additional sign-in prompts on every surface. For which two deployment surfaces will Microsoft Entra ID single sign-on work natively without requiring manual OAuth 2.0 configuration? (Select two!)
Multiple correct answersAMicrosoft Teams
BSharePoint site using the website channel via Direct Line iframe
CPower Apps canvas app
DCustom intranet portal using the Direct Line JavaScript snippet
EEmbedded website via a standalone Direct Line token endpoint
Explanation
Microsoft Entra ID single sign-on is natively supported in only two Copilot Studio channels: Microsoft Teams and Power Apps. In both channels, the user's existing Entra ID session is automatically passed to the agent, eliminating any additional sign-in prompt. All other deployment surfaces, including website and Direct Line channel implementations such as SharePoint iframes, JavaScript snippet embeds, and standalone Direct Line token endpoints, require manual OAuth 2.0 with PKCE configuration to authenticate users. This applies even when those users are already signed into Entra ID in their browser session. Organizations that require zero-prompt SSO across all agent surfaces must account for this limitation when planning their deployment architecture and consider whether the SharePoint iframe surface can be replaced with a Power Apps-embedded approach.
