Exam MD-101 topic 5 question 36 discussion

B is correct

B, the others only show if the policy is applied, but no audit info.

B - initially my thinking was that CA is applied on users"identity management/protection", so there should be some kind of insight or reports on account activities or audit trails in azure admin center, and duck has a nice reference and explanation thanks for that.

I would say B based on this: https://learn.microsoft.com/en-us/azure/active-directory/conditional-access/howto-conditional-access-insights-reporting "During sign-in, one or more Conditional Access policies may apply, granting access if certain grant controls are satisfied or denying access otherwise. Because multiple Conditional Access policies may be evaluated during each sign-in, the insights and reporting workbook lets you examine the impact of an individual policy or a subset of all policies." AND "View the breakdown of users or sign-ins for each of the conditions. You can filter the sign-ins of a particular result (for example, Success or Failure) by selecting on of the summary tiles at the top of the workbook. You can see the breakdown of sign-ins for each of the Conditional Access conditions: device state, device platform, client app, location, application, and sign-in risk."
