Final answer:
The use of Azure Backup does not necessitate a change in disk type as it is compatible with various disk types available in Azure. Disk selection is mainly influenced by performance, capacity, and cost.
Step-by-step explanation:
When considering the use of Azure Backup to protect the content of the virtual machine's disks on an administrative web interface server, the choice of disk type would not necessarily change solely based on the backup solution. Azure Backup is compatible with a wide range of Azure disk types. Therefore, the correct answer is: 1) It would not change the disk type. When selecting a disk type for your virtual machine, factors such as performance requirements, storage capacity, persistence, and cost considerations typically guide the decision, rather than the compatibility with Azure Backup, which supports both standard and premium managed disks.
