You will deploy a new Conditional Access policy named CAPolicy1 and use the What If tool to evaluate its impact while minimizing effect on users. What should the Enable policy setting for CAPolicy1 be set to?

Setting the policy to "Report only" allows you to evaluate the impact of CAPolicy1 without enforcing it. This means the policy will log its potential effects on user sign-ins and resource access, but it won't actually block or grant access. This is crucial for minimizing user impact while testing. "Off" would disable the policy entirely, preventing any evaluation. "On" would immediately enforce the policy, potentially disrupting users if there are unintended consequences.
