Because of a cost reduction program, many Microsoft SQL server instances will be consolidated on DB server VMs managed by NDB using a medium compute profile. Database administrators are concerned about DB storage capacity and are looking to expand it. Which NDB task should be performed?

Expanding the data disks attached to database-server virtual machines is done through the NDB task “Update Database Server VMs.” This workflow lets the administrator add or enlarge vDisks on the existing medium compute-profile servers without altering the compute profile itself and without touching Prism Element directly.

B. Expanding a vDisk in Prism Element bypasses NDB; the change will not be reflected in NDB’s inventory.
C. Changing a compute profile adjusts CPU/RAM, not storage size.
D. “Scale source database” pertains to adding database instances, not VM-level storage expansion.
