An administrator needs to restore a source database from a snapshot. The database shares the source volume with multiple other databases. How does…

The correct answer is A because NDB handles the database restore operation by copying the specific

database files from the snapshot volume to the source volume, without affecting the other

databases that share the same source volume. NDB uses a copy-on-write mechanism to create

snapshots and clones, which means that only the changes made to the database files are stored in

the snapshot or clone volume, while the original files are kept in the source volume. Therefore, when

restoring a source database from a snapshot, NDB only needs to copy the specific database files that

have been modified since the snapshot was taken, and overwrite them on the source volume. The

other options are not correct because they either cause data loss or unnecessary data transfer.

Option B is not correct because replacing the source volume with specific db disks would erase the

other databases that share the same source volume, which is not desirable. Option C is not correct

because replacing the source volume with the snapshot volume would also erase the other

databases that share the same source volume, as well as any changes made to the source database

after the snapshot was taken, which is not desirable. Option D is not correct because copying all

database files to the source volume would be inefficient and unnecessary, as only the modified files

need to be copied, and the other files are already present on the source volume. Reference:: Nutanix
