• Question 12:

  To create a 64-bit aggregate, which optional switch/flag/parameter/option to the aggr create command must be included?

  A. b 64
  B. B 64
  C. l 64
  D. L 64
  E. No optional switch/flag/parameter/option is needed because 64-bit aggregates are the default
  B. B 64

  The command to create a 64-bit aggregate is the same aggr create command that is present in Data ONTAP 7G for aggregate creation. The aggr create command has a new flag, -B, to specify the type of aggregate to create. It takes a value

  of either 32 or 64 and creates the respective type of aggregate. Therefore the aggr create command with -B 64 creates a 64-bit aggregate. The aggr create command without the -B flag by default creates a 32-bit aggregate.

  Here are some commands for creating different aggregate types in Data ONTAP 8.0:

  Creating a 64-bit aggregate:

  aggr create aggr_64 -B 64 5

  Creating a 32-bit aggregate using B flag:

  aggr create aggr_32 -B 32 5

  Creating a 32-bit aggregate without using B flag:

  aggr create default_aggr_32 5

  Note: the man pages do not include this option in later versions of DOT because 64-bit is now the default.

• Question 13:

  You have quiesced a SnapMirror relationship. Which command would re-establish the scheduled updates?

  A. snapmirror restart
  B. snapmirror resume
  C. snapmirror resync
  D. snapmirror update
  B. snapmirror resume

  ---

  snapmirror resume destination Resumes transfers to destination. The snapmirror resume command can be used either to abort a snapmirror quiesce in progress or undo a previously completed snapmirror quiesce. The command restores the state of the destination from quiescing or quiesced to whatever it was prior to the quiesce operation. http://wafl.co.uk/snapmirror/#sthash.5u3eilbK.dpuf

• Question 14:

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

  

  A. These are type "Solaris" LUNs.
  B. 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.
  D. 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.

  lun show [ -v | -m | -c ] [ all | mapped | offline | online | unmapped | staging | -g initiator_group | -n node | -l vol_name | lun_path ] Displays the status (lun_path, size, online/offline state, shared state) of the given LUN or class of LUNs. With the -v option supplied, additional information (comment string, serial number, LUN mapping, HA Pair Shared Volume Information) is also displayed. With the -m option supplied, information about lun_path to initiator_group mappings is displayed in a table format. With the -c option supplied, information about LUN cloning status is displayed.

  A specific LUN can be indicated by supplying its lun_path. When an initiator_group is specified, status is reported for all LUNs that are mapped to the initiator group. When a node is specified, status is reported for all LUNs that are mapped to initiator groups which contain that node. When staging is specified, information about the temporary LUNs preserved in the staging area is reported. When vol_name is specified, status is reported for all the LUNs in that volume. Mapped LUNs are ones with at least one map definition. A LUN is online if it has not been explicitly made offline using the lun offline command.

  

• Question 15:

  What types of migration are supported from 32-bit to 64-bit?

  A. migration of qtrees via QSM
  B. migration of volumes via ndmpcopy
  C. migration of volumes via SnapMirror
  D. Both A and B
  E. Both B and C
  F. Both A and C
  D. Both A and B

  ---

  Volume SnapMirror operates at the physical block level. It replicates the contents of an entire volume, including all Snapshot copies, plus all volume attributes verbatim from a source (primary) volume to a target (secondary) volume. Implicitly,

  the destination volume will be the same as the source volume.

  Since C is incorrect, A and B must be correct.

  Qtree snapmirror operates at the logical level, so it is unimportant that the destination system has a different volume configuration.

  ndmpcopy is similarly operating with data already read from the volume and so the destination volume type is not a consideration.

• Question 16:

  The snapvault snap sched -x command is used to ____________.

  A. schedule full backups
  B. cancel scheduled backups
  C. schedule baseline transfer
  D. schedule incremental backups
  D. schedule incremental backups

• Question 17:

  XML-files in /etc/stats/preset are used together with the sysstat command to customize the output.

  A. True
  B. False
  B. False

  https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_stats.1.html http://backdrift.org/man/ netapp/man5/na_stats_preset.5.html Data ONTAP provides some XML files that output a predetermined set of statistics that you can use without having to construct a script or type in a complicated command on the command line. The preset files are located in the /etc/stats/preset directory. To use a preset file, you add -p filename to your stats show or stats stop command line. You can also add counters on the command line. If any options you specify on the command

  line conflict with the preset file, your command line options take precedence.

  You can also create your own preset files.

• Question 18:

  If the security style is set to UNIX, CIFS client file access is determined by ___________.

  A. NT ACLs
  B. the last client to set permissions
  C. the mapped UNIX UID/GID of the CIFS client and the UNIX file permissions
  D. This is not allowed: A CIFS client cannot access files in a path set to a security style of UNIX
  C. the mapped UNIX UID/GID of the CIFS client and the UNIX file permissions

  https://library.netapp.com/ecmdocs/ECMP1196993/html/GUID-09C7812F-E6EA-47C6-AB79- EAB803E7A8EB.html

  For Data ONTAP to obtain the UID and GIDs for a CIFS user, it must first determine the user's UNIX- style name. It does this through user mapping.

• Question 19:

  You have connected all cables and disk shelves in a fabric-attached MetroCluster. Which command would verify that disks are connected and have dual paths?

  A. disk show
  B. sysconfig -p
  C. vol status -r
  D. storage show disk -p
  D. storage show disk -p

  The operator must ensure that the partner filer does not become operational at any time while a filer is in a takeover mode initiated by the use of this command http://backdrift.org/man/netapp/man1/na_cf.1.html

• Question 20:

  A mirrored volume has a failed disk, but there are no available spares in the pool from which the degraded plex was built. Data ONTAP will __________.

  A. halt all operations to volumes in that pool
  B. choose spare disks to reconstruct from the opposite pool
  C. warn you that there are no available spares from the proper pool
  D. "halt" after 24 hours if spare disks are not added to the proper pool
  C. warn you that there are no available spares from the proper pool

  ---

  Both `warn you that there are no available spares from the proper pool' and `halt after 24 hours if spare disk are not added to the proper pool' are correct answers. However, since Data ONTAP alerts you first, 'warn you that there are no available spares' is the best answer. https://library.netapp.com/ecm/ ecm_download_file/ECMP1196912
