Domain: Perform basic administrative tasks for Copilot and agents (25–30%) Type: Single choice

Q02 - Question

A company wants to give users agent capabilities for a common scenario as soon as possible. The IT team has limited time for configuration and customization. Which type of agent should the company use first?
