  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.

• Question 63:

  The usage for lun create is shown below. Options not in brackets are mandatory. lun create -s size -t ostype [ -o noreserve ] [ -e space_alloc ] lun_path This usage of the lun create command should be employed to create a new LUN of given size, with initially zero contents. The LUN is created at the lun_path given. No file should already exist at the given lun_path. The directory specified in the lun_path must be a qtree root directory.

  The size is specified in bytes. Optionally, a number followed by a one-character multiplier suffix can be used: c (1), w (2), b (512), k (1024), m (k*k), g (k*m), t (m*m). The size of the created LUN could be larger than the size specified, in order to get an integral number of cylinders while reporting the geometry using SAN protocols.

  The size of the LUN actually created is reported if it is different from that specified in the command. The mandatory ostype argument is one of: solaris (the LUN will be used to store a Solaris raw disk in a singleslice partition), windows (the LUN will be used to store a raw disk device in a single-partition Windows disk using the MBR (Master Boot Record) partitioning style), hpux (the LUN will be used to store HP-UX data), aix (the LUN will be used to store AIX data), vld (the LUN contains a SnapManager VLD), linux (the LUN will be used to store a Linux raw disk without any partition table), netware (the LUN will be used to store NetWare data), vmware (the LUN will be used to store VMware data), windows_gpt (the LUN will be used to store Windows data using the GPT (GUID Partition Type) partitioning style), windows_2008 (the LUN will be used to store Windows data for Windows 2008 systems), openvms (the LUN will be used to store Open-VMS data), xen (the LUN will be used to store Xen data), hyper_v (the LUN will be used to store Hyper-V data), solaris_efi (the LUN will be used to store Solaris_EFI data).

  By default, the LUN is space-reserved. To manage space usage manually, -o noreserve can be specified. Using this option will create a LUN without any space being reserved. Provisioning threshold events can be enabled by specifying -e space_alloc option. This option has to be used in conjunction with -o noreserve.

• Question 64:

  For OSSV sources, the qtree is the basic unit of SnapVault backups.

  A. True
  B. False
  B. False

  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.

• Question 65:

  Which three steps should be taken when troubleshooting a "stale nfs file handle" response to a NFS mount request on a Solaris system? (Choose three)

  A. check the client's fstab
  B. check the /etc/sd.conf file on the client
  C. check show mount -e to the storage system from the client
  D. check for connectivity to the storage system from the client
  E. check the output of the exportfs command on the storage system
  A. check the client's fstab
  D. check for connectivity to the storage system from the client
  E. check the output of the exportfs command on the storage system

  ---

  The fstab file reflects the defined filesystem mount paths (including NFS mounts). Always check network connectivity when a problem arises with a network service. The exportfs command will display the active exports on the storage system.

• Question 66:

  Using the output below, a co-worker determined that these are types "Solaris" LUNs. What would your destination be?

  lun show m LUN patch mapped to LUN ID ------------------------------------------------------- /vol/vol1/lun0 solaris igroup0 0 /vol/vol1/lun solaris- igroup1 0 /vol/vol1/qtree1/lun2 solaris igroup2 0 /vol/vol1/qtree1/lun3 solaris igroup3 0

  A. These are type "Solaris" LUNs.
  B. Not enough information is given here. Run the lun status command to get the information requested.
  C. Not enough information is given here. Run the lun show v command to get the information requested.
  D. Not enough information is given here. Run the lun map command to get the information requested.
  C. Not enough information is given here. Run the lun show v command to get the information requested.

• Question 67:

  You are trying to do a single file SnapRestore for a file, but you are receiving an error message that the directory structure no longer exists. Which is the most likely ?

  A. Once the directory structure has been deleted, you cannot restore the file using single file SnapRestore. You must now SnapRestore the volume.
  B. Snapshot copies have been created since the original directory structure was deleted.
  C. You must recreate the directory structure before trying to restore the file.
  D. You cannot restore a file to an alternate location.
  C. You must recreate the directory structure before trying to restore the file.

  You can restore a file only to the volume where it was originally located. The directory structure to which a file is to be restored must be the same as that specified in the path. If this directory structure does not exist, you must create it before restoring the file.

• Question 68:

  You cannot remove the SyncMirror license if one or more mirrored volumes exist.

  A. True
  B. False
  A. True

  ---

  You cannot disable the SyncMirror license if mirrored aggregates exist and are online. http://hd.kvsconsulting.us/netappdoc/801docs/html/ontap/onlinebk/GUID-5058FDA7-68AE-4693- B343- 0E9FFEDFC86C.html

• Question 69:

  Five minutes ago, you performed a single file SnapRestore on a large NFS file. 40% of your NFS users are now complaining about getting "stale file handles" for the file. Which is the most likely cause of this problem, and the best procedure to correct it?

  A. This might be due to an NFS storage system and client mismatch. Check to see that these users have the same version of the NFS client that existed at the time the snapshot was taken.
  B. NFS users why try to access a reverted file without first reopening it might get a "stale file handle" error message. Have the users try to reopen the file and see if the problem is resolved.
  C. After a single file SnapRestore, NFS users have to reboot their systems. Have them reboot their systems.
  D. These users are on a different subnet from the others. Start troubleshooting by checking their subnet.
  B. NFS users why try to access a reverted file without first reopening it might get a "stale file handle" error message. Have the users try to reopen the file and see if the problem is resolved.

  Reverting a file to a selected Snapshot copy Using snap restore to revert a single file to a selected Snapshot copy is practical when the file is so large that you cannot copy the previous file version from the Snapshot copy to the active file system. Before you begin Ensure that you notify the network users before reverting a file so that they know that the current data in the file will be replaced by that of the selected Snapshot copy.

  Note: NFS users who try to access a reverted file without first reopening it might get a stale file handle error message after the volume reversion.

• Question 70:

  In Data ONTAP, the root user is exempt from those two quotas: ______________. (Choose two)

  A. User quotas
  B. Tree quotas
  C. Root quotas
  D. Group quotas
  E. File quotas
  A. User quotas
  D. Group quotas

  ---

  http://backdrift.org/man/netapp/man1/na_quota.1.html

  User and group quotas do not apply to the root user or to the Windows Administrator account; tree quotas, however, do apply even to root and the Windows Administrator account.
