You manage an Azure Web App that has one Web Role instance, and several Worker Role instances. The
cloud service has multiple tiers. Different groups develop and maintain each tier.

performing extensive work.
What should you do?
A.
Create an availability set for each tier of the application.
B.
Implement auto-scaling for the Worker Roles.
C.
Create a resource group.
D.
Create an availability set with two or more virtual machines.
