Deploying a virtual machine into an availability zone protects it from a complete datacenter failure within an Azure region. Does this solution meet the goal?

The correct answer is False. Deploying a virtual machine into a single availability zone pins it to that zone. If the datacenters behind that zone suffer a complete failure, the VM goes down with them — a zonal VM is protected from failures in *other* zones, not from the failure of its own. As stated in the official documentation: "Many Azure regions provide availability zones, which are separated groups of datacenters within a region. Each availability zone has independent power, cooling, and networking." Protection against a complete datacenter failure comes from deploying resources *across multiple* availability zones, or from using zone-redundant services: when one zone goes down, instances in the remaining zones keep running. the option “True” (True) is incorrect because it describes the benefit of a multi-zone deployment, not of placing one VM in one zone. For a single zonal VM, a complete failure of its own zone's datacenter is exactly the scenario it is not protected against — which is why Microsoft recommends spreading VMs across availability zones for high availability.
