Final answer:
Deploying the virtual machines to a scale set does not ensure availability in case of a data center failure.
Step-by-step explanation:
No, deploying the virtual machines to a scale set does not meet the goal of ensuring the availability of services if a single data center fails.
A scale set is a feature in Azure that enables you to deploy and manage multiple identical virtual machines. However, it does not automatically provide redundancy across data centers.
To ensure high availability in case of a data center failure, you would need to deploy the virtual machines to multiple data centers and implement some form of load balancing or failover mechanism.
