You have an Azure subscription that contains a virtual machine named VM1. VM1 hosts a line-of-business application that is available 24 hours a day. VM1 has one network interface and one managed disk. VM1 uses the D4s v3 size.
You plan to make the following changes to VM1:
-> Change the size to D8s v3.
-> Add a 500-GB managed disk.
-> Add the Puppet Agent extension.
-> Attach an additional network interface.
Which change will cause downtime for VM1?

A. B. C. D.D
While resizing the VM it must be in a stopped state.
https://azure.microsoft.com/en-us/blog/resize-virtual-machines/The change that will cause downtime for VM1 is option D: Change the size to D8s v3.
Here's why:
Option A: Add a 500-GB managed disk Adding a managed disk to a VM does not require any downtime. You can add or remove managed disks from a running VM without any disruption.
Option B: Attach an additional network interface Attaching an additional network interface to a running VM also does not require any downtime. You can add or remove network interfaces from a running VM without any disruption.
Option C: Add the Puppet Agent extension Adding an extension to a VM does not require any downtime. You can install or uninstall extensions from a running VM without any disruption.
Option D: Change the size to D8s v3 Changing the size of a running VM requires the VM to be restarted, which will result in downtime. During the restart process, the VM will be unavailable, and any applications running on the VM will be unavailable as well. The amount of downtime will depend on the size of the VM and the amount of data being processed.
Therefore, the correct answer is D: Change the size to D8s v3.
