Deploy three VMs for a web app with high availability in case of a datacenter failure.
A
Place all VMs in one Availability Zone
B
Use a single Availability Set for all VMs
C
Distribute each VM across different Availability Zones
D
Assign each VM to a separate Availability Set
Explanation:
The correct answer is C. To ensure that at least two virtual machines are available if a single Azure datacenter becomes unavailable, you should distribute each virtual machine across different Availability Zones. Availability Zones are designed to protect resources from datacenter-level failures by hosting them in physically separate locations within the same Azure region. This setup ensures high availability even if one datacenter goes offline.
