wafl.default_security_style Specifies the default security style assigned to a new volume. All qtrees created on the volume get this as their security style. Legal values for this option are `unix', `ntfs', or `mixed'. The default value for this option is `unix', unless the node is an NTFS-only node, in which case the default is `ntfs'. Note: if cifs setup is run after setting wafl.default_security_style, the filer will become an NTFS security style filer.

Correct Answer: A

You must meet certain prerequisites before using SnapRestore:

-SnapRestore must be licensed on your storage system.

-There must be at least one Snapshot copy on the system that you can select to revert.

-The volume to be reverted must be online.

- The volume to be reverted must not be in use for data replication. http://hd.kvsconsulting.us/ netappdoc/733docs/html/ontap/onlinebk/GUID-A14081A3-9270-47EE- A1C1-EC52D3ABDBD0.html

disk show [ -o | -s | -n | -v | -a]

Used to display information about the ownership of the disks. Available only on systems with software- based disk ownership. -o lists all disks owned by the filer with the name -s lists all disks owned by the filer with the serial number -n lists all unassigned disks. -v lists all disks. -a lists all assigned disks.

Correct Answer: E

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. https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-B9CB3DA8E1AF-4BAC-A85B- 64C009010F4A.html

http://www.uow.edu.au/~blane/netapp/ontap/cmdref/man1/na_options.1.htm update [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destination For asynchronous mirrors, an update is immediately started from the source to the destination to update the mirror with the contents of the source.

For synchronous mirrors, a snapshot is created on the source volume which becomes visible to clients of the destination volume.

The update command must be issued on the destination node.status [ -l | -t | -q ] [ volume | qtree ... ] Reports status of all the SnapMirror relationships with a source and/or destination on this node. This command also reports whether SnapMirror is on or off. If any volume or qtree arguments are given to the command, only the SnapMirror relationships with a matching source or destination will be reported. If the argument is invalid, there won't be any status in the output.initialize [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destination Starts an initial transfer over the network. An initial transfer is required before update transfers can take place. The initialize command must be issued on the destination node. If the destination is a volume, it must be restricted (see na_vol(1) for information on how to examine and restrict volumes). If the destination is a qtree, it must not already exist (see na_qtree(1) for information on how to list qtrees). If a qtree already exists, it must be renamed or removed (using an NFS or CIFS client), or snapmirror initialize to that qtree will not work.snapmirror.access

This option determines which SnapMirror destination filers may initiate transfers, and over which network interfaces. When set to "legacy", SnapMirror uses the older snapmirror.allow to determine access. The option value is a string containing an expression which provides the access filter. An example of the options command for snapmirror.access is options snapmirror.access host=toaster,fridge. The default value is "legacy". See na_snapmirror(1) , na_snapmirror.allow

(5) and na_protocolaccess(8) for more details.

The snapmirror.allow file exists on the source filer used for SnapMirror.
