  ---

  Aggregates are never converted as part of an upgrade. An upgrade will not touch your data!

  A. Internet
  B. cluster partner
  C. same administration
  D. host same collection of subnets
  D. host same collection of subnets

• Question 84:

  Which MetroCluster configuration procedure is recommended for re-establishing a mirrored volume that was in a level-0 resynchronization state when it failed?

  A. Determine which volumes are at the remote and disaster sites.
  B. Re-create the synchronous mirror.
  C. Rejoin the two volumes.
  D. Turn on power to the cluster node at the disaster site.

  1.

  Validate that you can access the remote storage by entering the following command:

  aggr status -r

  Note: A (level-0 resync in progress) message indicates that a plex cannot be rejoined.

  2.

  Turn on the power to the node at the disaster site. After the node at the disaster site boots up, it displays the following:

  Waiting for giveback...(Press Ctrl-C to abort wait)

  3.

  If the aggregates at the disaster site are online, take them offline by entering the following command for each aggregate that was split:

  aggr offline disaster_aggr

  disaster_aggr is the name of the aggregate at the disaster site. Note: An error message appears if the aggregate is already offline.

  4.

  Destroy every target plex that is in a level-0 resync state by entering the following command:

  aggr destroy plex_name

  5.

  Re-create the mirrored aggregates by entering the following command for each aggregate that was split:

  aggr mirror aggr_name -v disaster_aggr

  aggr_name is the aggregate on the surviving site's node. disaster_aggr is the aggregate on the disaster site's node. The aggr_name aggregate rejoins the disaster_aggr aggregate to reestablish the MetroCluster configuration.

  6.

  Enter the following command at the partner node:

  cf giveback

  The node at the disaster site reboots.

• Question 85:

  Which two statements apply to the fs_size_fixed volume option? (Choose two.)

  A. The default setting is on.
  B. This option is automatically set to be on when a volume becomes a SnapMirrored volume.
  C. This option turns to off after the snapmirror break command is issued for the relationship.
  D. This option causes the SnapMirror destination volume to remain the same size and not grow or shrink when a SnapMirrored volume relationship is broken.
  B. This option is automatically set to be on when a volume becomes a SnapMirrored volume.
  D. This option causes the SnapMirror destination volume to remain the same size and not grow or shrink when a SnapMirrored volume relationship is broken.

  ---

  This option causes the file system to remain the same size and not grow or shrink when a SnapMirrored volume relationship is broken, or when a vol add is performed on it. This option is automatically set to be on when a volume becomes a SnapMirrored volume. It will remain on after the snapmirror break command is issued for the volume. This allows a volume to be SnapMirrored back to the source without needing to add disks to the source volume. If the volume size is larger than the file system size, turning off this option will force the file system to grow to the size of the volume. The default setting is off. http://wafl.co.uk/vol-2/#sthash.DbEHR4YS.dpuf

• Question 86:

  To manage SnapVault relationships with an NDMP management application, you must specify a:

  A. directory path
  B. volume and qtree
  C. SnapVault license
  D. username and password
  D. username and password

  ---

  Add a new backup user to the Backup Operators useradmin group list. Enter the following command:

  useradmin user add backupuser -g "Backup Operators"

  Generate an NDMP password for the new user. Enter the following command:

  ndmpd password backupuser

  The NDMP password is used to authenticate the NetBackup media server to the storage system. This password is required for setup on the NetBackup management station. https://library.netapp.com/ ecmdocs/ECMM1278284/html/

• Question 87:

  The OSSV agent on the primary system listens to TCP port 10000 for all SnapVault communications.

  A. True
  B. False
  A. True

  ---

  https://communities.netapp.com/servlet/JiveServlet/previewBody/4791-102-2-13466/tr-3466.pdf

  Pg 17

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

• Question 88:

  Which set of protocols provide block-level access to NetApp storage?

  A. SNA and RPC
  B. iSCSI and FCP
  C. HTTP and FTP
  D. CIFS and NFS
  B. iSCSI and FCP

  ---

  iSCSI and Fiber Channel encapsulate SCSI protocol, simulating direct disk access. These are commonly referred to as a block storage protocols. FCoE is another such protocol. CIFS and NFS, HTTP and FTP provide file access not block access.

• Question 89:

  Which two commands would help you troubleshoot a LUN that cannot be accessed by a host? (Choose two.)

  A. fcp show wwpn
  B. fcp wwpn
  C. igroup show
  D. lun show -err
  E. lun show -v
  C. igroup show
  E. lun show -v

  ---

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

  igroup show [ -v ] [ initiator_group ] Displays the nodes in an initiator group and their aliases, set with the fcp wwpnalias command. If no initiator_group is specified, the members of all initiator groups are displayed. You can use the -v option to get a verbose listing.

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

  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.

• Question 90:

  For automatic user name mapping to occur for a CIFS and UNIX user name that are the same, you must do what?

  A. Enter the CIFS user in the NIS database.
  B. Enter the user names in the /etc/hosts.equiv file.
  C. Use both a NIS server and a Domain Controller in the network.
  D. Nothing: mapping will occur if user name authentication is available.
  D. Nothing: mapping will occur if user name authentication is available.

  If the user names in the UNIX password database are identical to the Windows names, you need not provide the mapping information in the /etc/usermap.cfg file.
