The correct options are Create and configure an action group and Create an Azure Service Health alert.

Create an Azure Service Health alert is the right choice because Service Health reports platform events that affect your subscription such as planned maintenance and health advisories, and alerts can be created to notify you when Microsoft announces scheduled maintenance that could impact your services.

Create and configure an action group is required because action groups define who gets notified and how, and they support SMS as a notification channel so you can have the platform send an SMS when the Service Health alert fires.

Create a Resource Health alert is incorrect because Resource Health informs you about the health status of individual resources and their availability, and it does not provide subscription level scheduled maintenance announcements from the platform.

Enable Azure Security Center is incorrect because Security Center focuses on security posture and threat protection, and it does not send platform maintenance or scheduled maintenance notifications.
