The AB-900 exam is demanding, but its difficulty is specific, not mysterious: unfamiliar question formats, time pressure, and a few heavily weighted domains. All three respond to the same remedy — repeated, timed exposure to exam-style questions.

The AB-900 exam consists of 40-50 questions with a time allowance of 65 minutes minutes. Practicing full sets under a similar time cap is the most direct way to make sure pacing never costs you points on exam day.
Microsoft offers these training resources for candidates:

Hotspot Question
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Correct Answer:
Explanation:
Box 1: Yes
Users with a Microsoft 365 E5 (or E3) license have access to Microsoft 365 Copilot Chat at no additional cost. Within Copilot Chat, they can use Agent Builder to create basic Copilot agents, including agents grounded in public web data (when the feature is enabled in the tenant). A full Microsoft 365 Copilot add-on license is not required for this basic agent creation capability.
Box 2: Yes
The Analyst agent (along with other premium agents like Researcher) is a Microsoft-provided advanced reasoning agent. It is only available to users who have the Microsoft 365 Copilot add- on license. Users with only E3/E5 base licenses cannot access this premium agent.
Box 3: Yes
This is one of the key features of Agent Builder in Microsoft 365 Copilot. Users can simply describe in natural language what they want the agent to do, and Copilot assists in creating and configuring the agent.
