Which THREE of the following are prerequisites for configuring an Always On Availability Group on Azure VMs with automatic failover? (Choose Three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
All VMs must be in the same availability set or availability zones.
Options A, B, and E are correct. A domain controller (B) is needed for Windows Server Failover Clustering. All VMs must be in the same availability set or availability zones (A) to ensure high availability. An internal load balancer (E) is required for the availability group listener to support automatic failover. Option C is incorrect because SQL Server authentication is not a prerequisite; Windows Authentication is used for cluster communication. Option D is incorrect because VMs can be in different regions, but automatic failover across regions is not supported without additional configuration (e.g., Azure Site Recovery).
