Microsoft Azure Administrator Associate AZ-104 Practice Question

To increase storage capacity by adding a separate data disk, you should attach a new managed disk through the Azure portal. This process involves navigating to the VM's Disks settings and adding a new disk, which can then be formatted and used by the VM. Increasing the size of the existing operating system disk would not add a separate disk but merely expand the existing one. Modifying the virtual machine's availability set does not affect its storage capacity. Changing the VM size adjusts compute resources like CPU and memory but does not add additional disks.
