You are the Azure admin and are responsible for two virtual machines, each hosting the same financial application. Your manager has asked you to ensure that:
- The application always be available, even when one VM is being updated
- Each VM is attached to a different switch and different power source
- Only one VM is active at a time
How can you accommodate these requirements? Choose one answer below.
A. Place each VM in a different fault domain
B. Place both VMs in the same availability set
C. Place each VM in a different availability set
D. Place both VMs in the same fault domain
The answer is B. An availability set contains 5 update domains and 2 fault domains. By placing both VMs in the same availability set, you ensure Azure will automatically place each one in a different update domain. This, in turn, ensures that if one VM is upgraded, the other remains up and running.
