  A. VLD
  B. VIIP
  C. File
  D. Block
  D. Block

  ---

  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 122:

  Easy to use interactive mechanism for setting up initiator groups, LUNs, and mapping configuration.

• Question 125:

  How do you migrate LUNs under volumes from 32-bit to 64-bit?

  A. lrep
  B. ndmpcopy
  C. rsync
  D. snapvault
  B. ndmpcopy

  Think of ndmpcopy as a sort of ftp for SAN. You can use it to copy files from one volume to another. Because the file is read from one volume and written to another, the constraints of volume types are not an issue.

• Question 126:

  Which OSSV tool would you use to perform an OSSV unattended installation?

  A. msipackage
  B. svunattendossv
  C. svconfigpackager
  D. unattendpackager
  C. svconfigpackager

  ---

  The reference for this questionis an old version of a TR. It is likely that this question will be removed from the NSO-155 exam.

  The svconfigpackager is a binary in the OSSV client which can be used to create an unattended installation package using an answer file.

• Question 127:

  Which statement is true about ASIS deduplication license with Data ONTAP 8.1?

  A. The existing 8.0 license key is used.
  B. A new license key is generated.
  C. The license is capacity-based.
  D. The license no longer exists.
  D. The license no longer exists.

  Changes to deduplication in 8.1 7-mode Starting with Data ONTAP 8.1, you can enable the deduplication feature without adding a license. For deduplication, no limit is imposed on the supported maximum volume size. The maximum volume size limit is determined by the type of storage system regardless of whether deduplication is enabled.

• Question 128:

  Protection Manager is an optional component of the Operations Manager that can be licensed and accessed from the NetApp Management Console (NMC).

  A. True
  B. False
  B. False

  B. cifs shares -add /vol/vol2/home/netapp
  C. cifs shares -add netapp vol/vol2
  D. cifs shares -add netapp /vol/vol2/home
  D. cifs shares -add netapp /vol/vol2/home

• Question 130:

  Which three configurations would increase data transfer rates in a volume SnapMirror environment for traditional volumes?

  A. The destination volumes are flexible volumes.
  B. The destination and source contain disks of the same size.
  C. The destination and the source contain RAID groups of the same size.
  D. The destination and source contain the same number of raid groups.
  E. The destination and source storage systems are no father than 30 meters apart.
  B. The destination and source contain disks of the same size.
  C. The destination and the source contain RAID groups of the same size.
  D. The destination and source contain the same number of raid groups.

  ---

  By aligning the performance of the source and destination, optimal data transfer (aka replication) rates can be attained. Flexvols don't matter, and there is no measurable difference between the performance of a network over a 30m or 3m cable.
