Netapp Data ONTAP 7-Mode Administrator NS0-155 Exam Dumps: Updated Questions & Answers (October 2025)

When you rejoin split aggregates, Data ONTAP mirrors the data from one aggregate to the other and destroys data that existed on that aggregate before the rejoin.

The data structures that are backed up and restored through SnapVault depend on the primary system.

On systems running Data ONTAP, the qtree is the basic unit of SnapVault backup and restore.

SnapVault backs up specified qtrees on the primary system to associated qtrees on the SnapVault secondary system. If necessary, data is restored from the secondary qtrees back to their associated primary qtrees.

On open systems storage platforms, the directory is the basic unit of SnapVault backup. SnapVault backs up specified directories from the native system to specified qtrees in the SnapVault secondary system.

If necessary SnapVault can restore an entire directory or a specified file to the open systems platform.

The destination system uses a slightly more disk space and directories than the source system.

quota resize volume

Adjusts currently active quotas in the specified volume to reflect changes in the /etc/quotas file. For instance, if you edit an entry in /etc/quotas to increase a user's quota, quota resize will cause the change to take effect. The volume name may be omitted if the system has only one volume. quota resize can be used only when quotas are already on. Because it does not rescan the file system to compute usage, quota resize is faster than turning quotas off and then on again. quota resize will apply all updated entries in /etc/quotas; however, it will generally ignore newly added entries. A newly added entry will only take effect if the corresponding user or group has an active quota as a result of updating a file subject to default quotas.

To convert an asynchronous SnapMirror relationship to a synchronous SnapMirror relationship, on the administration host, edit the snapmirror.conf file on the destination system to change the schedule to sync.

Ensure that both plexes of the mirrored aggregate you are splitting are online and operational.

SyncMirror is essentially a RAID-1 mirror; hence the name. The best practice is to mirror storage of equal performance; i.e. identical RAID groups and disk sizes (number of spindles, IOPS). If you were to mirror two storage devices of different performance, the slower device would be the limiting factor.

After you revert a volume to a selected Snapshot copy, you lose all the Snapshot copies that were taken after the selected Snapshot copy.
