Final answer:
Availability Zones in Azure can protect virtual machines from a datacenter failure, but not a region failure.
Step-by-step explanation:
Yes, you can use Availability Zones in Azure to protect Azure virtual machines from a Datacenter failure. An Availability Zone is a physically separate datacenter within an Azure region, providing redundancy and fault tolerance. If a datacenter fails, the virtual machines in that datacenter can failover to another datacenter within the same region, ensuring that your applications remain available .For example, let's say you have a virtual machine running in Availability Zone 1. If there is a datacenter failure in Availability Zone 1, Azure will automatically failover your virtual machine to Availability Zone 2, protecting it from the failure. In contrast, Region failure refers to a situation where an entire Azure region becomes unavailable. Availability Zones do not protect against region failures. To protect against region failures, you can use Azure Site Recovery to replicate your virtual machines to a different region.
