Correct Answer: C While resizing, the VM must be in a stopped state, therefore there will be a downtime. Reference: https://azure.microsoft.com/en-us/blog/resize-virtual-machines

Nowadays you don't need to stop the vm prior to resizing, even if the vm is running, you may resize, but it will restart the vm causing downtime anyway. Also another advantage of stopping vm prior to resizing is that it gives more choices to choose from in the vm list.

Selected Answer: C

C. Change the size to D8s v3. Changing the size of an Azure virtual machine involves a stop and restart of the virtual machine, which will cause downtime for the line-of-business application hosted on VM1. This downtime can be minimized by using Azure Availability Sets or by taking appropriate steps to prepare for the change, such as backing up data or moving the application to another virtual machine. Adding a managed disk, installing the Puppet Agent extension, or enabling Desired State Configuration Management should not cause downtime for VM1.

Selected Answer: C

C is correct as resizing requires shutdown because of the hardware specs also because the current hardware cluster may not be able to support it and hence VM will be moved to another one that have the resources to take on the new size
