AB-620 Practice Test

Microsoft Certified: AI Agent Builder Associate

AB-620 tests whether you can actually build production-grade agents in Copilot Studio — MCP tool integration, multi-agent collaboration with A2A protocol, Foundry and Fabric integration, and agent evaluation — not just create a basic topic-based chatbot.

Our 500 scenario-based questions cover the full AB-620 blueprint across three domains: planning and configuring agent solutions (integration planning, identity strategy, channels and deployment, responsible AI strategy, security and governance, reusable agent components, agent flows, and topic configuration including adaptive cards and generative answers), integrating and extending agents in Copilot Studio (connecting to enterprise knowledge sources including Copilot connectors and Azure AI Search, adding tools including MCP tools and REST APIs, configuring multi-agent collaboration with Foundry, Fabric, and A2A protocol, and integrating agents with Azure services — the largest domain at 40-45%), and testing and managing agents (evaluating agent performance with test sets, and implementing application lifecycle management including solutions, environment variables, and Power Platform Pipelines). Every question is grounded against live Microsoft Copilot Studio and Microsoft Learn documentation.

Why Practice with MSCertQuiz?

Microsoft Learn teaches concepts. We prepare you for the actual exam.

1

Deep coverage of the newest agent-integration surface most question banks haven't caught up to — MCP tools, Agent2Agent (A2A) protocol, Foundry agent integration, and Fabric data agents

2

Real multi-agent and enterprise-knowledge scenarios across Copilot connectors, Azure AI Search, and computer-using agents, matching how production agent solutions are actually architected

3

Full ALM and governance content most competitors skip: solution-based deployment, environment variables, Power Platform Pipelines, responsible AI strategy, and DLP/security-role impact on agent components

4

Every question verified against live Microsoft Copilot Studio and Microsoft Learn documentation before it ships, so content stays accurate as agent-building capabilities keep evolving

What Our Users Say

“I'd built topic-based agents for a while but never touched MCP tools or A2A multi-agent collaboration before this. The integration questions closed real gaps. Passed on my first attempt.”

PY

Priyanka Y.

AB-620 Certified

“The Foundry and Fabric agent integration domain was way more detailed than I expected from a practice test, and matched the real exam almost exactly.”

MF

Marco F.

Copilot Studio Developer

“As someone who mostly configures topics and knowledge sources, the ALM and Power Platform Pipelines questions filled real gaps between what I knew and what the exam actually tests.”

AB-620 Frequently Asked Questions

Everything you need to know about the AB-620 AI Agent Builder certification

What is AB-620?
AB-620 (Microsoft Certified: AI Agent Builder Associate) is a certification validating the ability to build, extend, and integrate custom agents for enterprise-grade solutions in Microsoft Copilot Studio, including multi-agent collaboration, enterprise knowledge sources, and tool integration.
How much does the AB-620 exam cost and how long is it?
The AB-620 exam costs $165 USD, runs approximately 120 minutes, and has a passing score of 700 out of 1000. Confirm current pricing and duration on the official certification page before booking, since exam details can shift alongside Copilot Studio feature updates.
What is the passing score for AB-620?
The passing score for AB-620 is 700 out of 1000, the same threshold used across nearly all Microsoft role-based certification exams. Scoring is scaled, so 700 represents roughly 70% competency spread across all three exam domains rather than a simple raw percentage.
What topics are covered on AB-620?
AB-620 covers three domains: Plan and configure agent solutions (30-35%) — architecture, identity, governance, agent flows, and topics; Integrate and extend agents in Copilot Studio (40-45%, the largest domain) — enterprise knowledge sources, MCP tools, multi-agent collaboration with Foundry/Fabric/A2A protocol, and Azure integration; and Test and manage agents (20-25%) — evaluation and application lifecycle management.
How hard is AB-620?
AB-620 is a scenario-heavy exam that expects real hands-on experience building agents in Copilot Studio, not just familiarity with basic topic authoring. Candidates comfortable with simple chatbots often find the multi-agent collaboration (A2A protocol, Foundry and Fabric agent integration) and MCP tool configuration questions the hardest, since these are newer, fast-evolving capabilities.
How long should I study for AB-620?
Candidates already building and integrating agents in Copilot Studio with MCP tools or multi-agent collaboration should plan 3-5 weeks, focused on the Integrate and extend domain given its exam weight. Candidates newer to agent building should plan 6-8 weeks. We recommend working through Microsoft Learn's AB-620 learning path first, then practicing with 500 scenario-based questions spread across all three domains in proportion to their exam weight.
What are the prerequisites for AB-620?
There are no enforced prerequisites to register for AB-620, but it is designed for professional developers or advanced builders with intermediate knowledge of generative AI concepts (models, orchestration, RAG, MCP, A2A protocol), prompt engineering, REST APIs, and experience configuring agents with knowledge sources, instructions, tools, and topics in Copilot Studio.
Who should take AB-620?
AB-620 is aimed at IT application developers, consultants, and independent software vendor (ISV) partners who build, extend, and integrate custom agents for enterprise-grade AI solutions. It pairs well with AI-103 (Developing AI Apps and Agents on Azure) for candidates working across both Copilot Studio and Azure AI Foundry, and with AB-100 (Agentic AI Business Solutions Architect) for a broader agentic-AI credential portfolio.
