An action an alert rule named Alert1 that uses AG1.
You need to identify who will receive an email notification when Alert1 is triggered.
Who should you identity?
Select an option, then click Submit answer.
Reference / correct answer:
Only identities that are explicitly configured as Email/SMS/Push/Voice receivers in the action group (AG1) will receive email notifications.
Azure RBAC role assignments (for example, assigning Monitoring Reader to User1, Group1, or managed identities) do not cause Azure Monitor action group email notifications to be sent to those identities automatically. Also, managed identities/service principals cannot be used as email recipients.
Given the answer choices, the only valid recipient that can receive email is the Azure AD user explicitly listed: User1.
