Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

C
Distractor review
Microsoft Entra ID Identity Protection
Identity Protection analyzes risks and automates responses, but does not provide identity federation for external users.
D
Distractor review
Microsoft Entra ID Conditional Access
Conditional Access enforces access policies, but does not manage external identity providers or federation.
