Every VM contains a ____________________, which is not a managed disk. The ____________________ provides short-term storage for applications and processes and is intended to only store data such as page or swap files. Data on the ____________________ may be lost during a maintenance event or when you redeploy a VM. During a standard reboot of the VM, the data on the ____________________ should persist. However, there are cases where the data may not persist, such as moving to a new host. Therefore, any data on the ____________________ should not be data that is critical to the system. On Windows virtual machines, this disk is labeled as the D: drive by default and it used for storing pagefile.sys. On Linux virtual machines, the disk is typically /dev/sdb and is formatted and mounted to /mnt by the Azure Linux Agent.
