Question 1
Tailspin Toys runs two application VMs and must keep service available if an entire datacenter zone in the region fails. How should the instances be deployed? Choose ONE.
- Deploy separate VM instances across availability zones
- Place two or more VMs in an availability set
- Deploy the workload with an Azure Virtual Machine Scale Set
- Use the standard Azure resource move operation after validating dependencies
Correct Answer: A
Correct Answer
Answer A is correct because The Tailspin Toys scenario turns on this requirement: separate VM instances must be isolated across physically distinct datacenter zones to tolerate a zonal datacenter failure. Availability zones are physically separate datacenter zones with independent power, cooling, and networking, so distributing instances across zones protects against a datacenter-level failure. That makes this the appropriate choice.
Incorrect Answers
Answer B is incorrect because Availability sets spread VMs across fault domains and update domains within a datacenter-oriented deployment, reducing correlated hardware and maintenance impact where zones are not used. It misses the key condition in the Tailspin Toys case: separate VM instances must be isolated across physically distinct datacenter zones to tolerate a zonal datacenter failure.
Answer C is incorrect because Tailspin Toys must satisfy this condition: separate VM instances must be isolated across physically distinct datacenter zones to tolerate a zonal datacenter failure.

The VM size determines compute resources and supported capabilities such as vCPU count, memory, disk and network limits, so the selected SKU must satisfy workload and regional availability needs. This choice addresses another concern.
Answer D is incorrect because Supported VMs can move between resource groups or subscriptions with Azure resource move operations, but required dependent resources and special-case restrictions must be validated first. That feature is valid Azure functionality, but The requirement for Adventure Works is: Virtual Machine Scale Sets manage the VM fleet and autoscale rules adjust instance count.
