• Preparing agents for deployment and ongoing maintenance

Preparation Tips

Practice testing agents with realistic scenarios and reviewing results. Understand how solutions, environment variables, and deployment pipelines support consistent management across development, test, and production environments.

How to Prepare for the AB-620 Exam

AB-620 preparation should combine Microsoft Learn content, hands-on Copilot Studio experience, and scenario-based practice.

1. Start with the Official Study Guide

Mark each topic as:

• Strong: You can explain and apply it confidently.
• Developing: You understand the basics but need more practice.
• Needs review: You need to revisit the concept.

Prioritize the integration domain because it carries the largest exam weighting.

2. Build Agents in Copilot Studio

Hands-on practice is essential. Create a sample agent and work through tasks such as:

• Configure instructions and knowledge sources
• Create topics and variables
• Add agent flows
• Configure connectors and tools
• Create adaptive cards
• Add custom prompts
• Test agent responses
• Review and improve the agent

3. Learn Integration Concepts

Review the purpose and use cases of:

• REST APIs
• Custom connectors
• MCP servers
• Azure AI Search
• Microsoft Foundry
• Microsoft Fabric
• A2A protocol
• Enterprise connectors

Focus on understanding how each integration fits into an agent solution.

4. Understand Responsible AI and Security

Enterprise agents must be designed with security and governance in mind.

Study:

• Identity and access management
• Data access permissions
• Responsible AI practices
• Enterprise governance
• Secure integration patterns
• Error handling and monitoring
• Human approval workflows

5. Practice Scenario-Based Questions

For each practice question, ask:

• What is the business requirement?
• Does the agent need knowledge, a tool, or a workflow?
• Which integration is most appropriate?
• How should the solution be tested?
• What security or governance requirement applies?

Review the reasoning behind every answer, not just whether you selected the correct option.

Four-Week AB-620 Study Plan

This suggested plan can be adjusted according to your experience and available study time.

Final Week Checklist

Before exam day:

• Review all three skill areas.
• Revisit the integration topics you find difficult.
• Build and test at least one complete agent solution.
• Practice using knowledge sources, tools, and agent flows.
• Review MCP, APIs, A2A, and multi-agent collaboration.
• Understand testing, evaluation, and ALM.
• Confirm your exam appointment and testing requirements.

AB-620 Practice Questions

These original practice questions are designed to reinforce AB-620 concepts. They are not official Microsoft exam questions.

Question 1: Agent Knowledge Sources

A company wants its Copilot Studio agent to answer employee questions using approved internal documentation. The content changes regularly, and employees should only access information they are authorized to view.

Which approach is most appropriate?

A. Place all documentation directly into the agent’s instructions
B. Connect the agent to an appropriate enterprise knowledge source with access controls
C. Give every employee administrator access to the source system
D. Disable authentication so the agent can answer everyone

Correct Answer: B. Connect the agent to an appropriate enterprise knowledge source with access controls

Explanation: Enterprise knowledge sources allow agents to retrieve relevant information while supporting appropriate access controls. Instructions alone are not a suitable replacement for managing changing business content.

Question 2: Workflow Automation

A Copilot Studio agent must submit a service request, wait for manager approval, and then notify the requester of the outcome.

Which approach best supports this requirement?

A. Use only a static welcome message
B. Configure an agent flow with a human-in-the-loop approval step
C. Add the approval instructions to the agent’s description
D. Disable all tools and connectors

Correct Answer: B. Configure an agent flow with a human-in-the-loop approval step

Explanation: An agent flow can orchestrate actions and include a human approval step before continuing the process.

Question 3: API Integration

An organization needs its agent to retrieve real-time order status from a business application that exposes a REST API.

What should the builder consider using?

A. A custom connector or API tool configured for the REST API
B. A static topic with manually entered order information
C. A data classification label only
D. A local variable without an external data source

Correct Answer: A. A custom connector or API tool configured for the REST API

Explanation: A configured API integration allows the agent to retrieve current information from the business application. Authentication, permissions, and input/output handling should also be considered.

Question 4: Multi-Agent Collaboration

A solution requires a Copilot Studio agent to delegate a specialized task to an existing agent built on another platform. The agents need to communicate using a supported agent-to-agent approach.

Which concept is most relevant?

A. A2A protocol
B. Data retention policy
C. Static application testing
D. Network address translation

Correct Answer: A. A2A protocol

Explanation: Agent2Agent (A2A) is relevant to communication and collaboration between agents. The solution design should also consider authentication, responsibilities, and error handling.

Question 5: Agent Evaluation

A team has created an agent and wants to measure how well it responds to a set of realistic user questions before deployment.

What should the team do?

A. Deploy the agent immediately without testing
B. Create a test set, choose an evaluation method, and review the results
C. Remove all knowledge sources
D. Replace the agent with a static FAQ page

Correct Answer: B. Create a test set, choose an evaluation method, and review the results

Explanation: Testing and evaluation help identify response quality issues and determine whether the agent meets its intended requirements before deployment.
