An Azure Virtual Machine Scale Set is best used when you need to:
ARun a single one-off batch job and then delete the result
BEncrypt application secrets at rest on a managed key store
CRun and automatically scale a group of identical Linux or Windows VMs behind a load balancer
DPermanently host a static website with no traffic variation
Answer & Solution
Correct answer: C. Run and automatically scale a group of identical Linux or Windows VMs behind a load balancer
VMSS provisions and manages a group of identical VMs that can scale automatically based on metrics like CPU or queue depth, typically behind a load balancer. It's the IaaS-level equivalent of an auto-scaling group. Single jobs, static sites, and secret stores have different services.
