What should you deploy?

You plan to deploy three Azure virtual machines named VM1, VM2, and VM3. The virtual machines will host a web app named App1.

You need to ensure that at least two virtual machines are available if a single Azure datacenter becomes unavailable.

What should you deploy?
A . all three virtual machines in a single Availability Zone
B . all virtual machines in a single Availability Set
C . each virtual machine in a separate Availability Zone
D . each virtual machine in a separate Availability Set

Answer: C

Explanation:

An Availability Zone in an Azure region is a combination of a fault domain and an update domain. For example, if you create three or more VMs across three zones in an Azure region, your VMs are effectively distributed across three fault domains and three update domains. The Azure platform recognizes this distribution across update domains to make sure that VMs in different zones are not updated at the same time.
