You have an app named App1 that runs on two Azure virtual machines named VM1 and VM2. You plan to implement an Azure Availability Set for App1. The solution must ensure that App1 is available during planned maintenance of the hardware hosting VM1 and VM2. What should you include in the Availability Set?
Show answer
Answer: D
Explanation
Correct Answer: D When you create an Availability Set, the hardware in a location is divided into multiple update domains and fault domains. An update domain is a group of VMs and underlying physical hardware that can be rebooted at the same time. VMs in the same fault domain share common storage as well as a common power source and network switch. During scheduled maintenance, only one update domain is updated at any given time. Update domains aren't necessarily updated sequentially. So, we need two update domains.
