A volume created using the vol command (see na_vol(1)) is a snaplock volume when either the enterprise or compliance option is chosen. Enterprise and compliance SnapLock volumes allow different levels of security assurance. https:// library.netapp.com/ecmdocs/ECMP1196889/html/GUID-D4533C47-441D-41AB-A8A2- 272A2BFC431C.html

  SnapLock operates fundamentally at the file level.

  A. Via /etc/hosts.equiv file

  B. QSM access list modifiable via svconfigurator

  C. Contents inside a file called access and located in OSSV /snapvault/etc

  D. MD5 based authentication between SnapVault primary and secondary, with changeable password

• Question 64:

  The snapvault update command is only available on the secondary system.

  A. True

  B. False

  OSSV hosts listen for communications from NDMP manager applications on port 10000 by default.

• Question 66:

  To restore a qtree protected with SnapVault from the secondary storage system to the primary storage system, you can ______________. (Choose two.)

  A. restore to a non existing qtree with DOT 7. 2

  B. add the new qtree to the primary storage system with DOT 7.2

  C. overwrite the existing qtree on the primary storage system with DOT 7.3

  D. delete the existing qtree from the secondary storage system with DOT 7.3

  Correct Answer: AC

  You use the snapvault restore command to restore a backed-up qtree saved to the secondary system. Starting with Data ONTAP 7.3, you can restore the data to an existing qtree on the primary system using baseline restore or incremental restore.

• Question 67:

  The snapvault restore command is run on the _________.

  A. secondary system to push data to the primary system

  B. primary system to pull data from the secondary system

  C. secondary system to pull data from the primary system

  D. secondary system to push data to the primary storage system

  Correct Answer: B

  https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapvault.1.html

  The snapvault command has a number of subcommands. The set of subcommands differs on the primary and secondary.

  On the primary, the subcommands allow users to configure and manage a set of snapshots for potential replication to the secondary, to abort replication transfers to the secondary, to check status, to restore data from the secondary, and to

  release resources when a primary qtree will no longer be replicated to a secondary.

  On the secondary, the subcommands allow users to configure and manage the replication of primary paths to secondary qtrees, to configure and manage the snapshot schedules which control when all the qtrees in a secondary volume are

  updated from their respective primary paths and how many snapshots to save, to abort transfers, to check status, and to release resources preserved to restart backups from a restored qtree.

• Question 68:

  The qtree specified for ____ must not exist on the secondary system before you run the ____ command.

  A. pri_qtree_path, snapvault start

  B. sec_qtree_path, snapvault start

  C. pri_qtree_path, snapvault initialize

  D. sec_qtree_path, snapvault initialize

  Correct Answer: B

  snapvault initialize is not a valid command http://backdrift.org/man/netapp/man1/na_snapvault.1.html snapvault start -r [options] -S [prim_system:] prim_qtree_path [sec_system:] sec_qtree_path pri_qtree_path is not a valid command
