Which feature provides preferred protection for the root volume of a storage virtual machine (SVM)?

A.
SnapVault

B.
load-sharing mirror

C.
SnapMirror

D.
SyncMirror

Explanation:
To protect the Storage Virtual Machine (SVM) namespace root volume, you can create a load-sharing mirror volume on every node in the cluster, including the node
in which the root volume is located. Then you create a mirror relationship to each load-sharing mirror volume and initialize the set of load-sharing mirror volumes.
