NetApp NS0-155 Online Questions & Answers

• Question 151:

  Which exportfs command will temporally export the resource while ignoring the options specified in the / etc/exports file?

  A. exportfs v
  B. exportfs u
  C. exportfs a
  D. exportfs i
  D. exportfs i

  ---

  https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_exportfs.1.html exportfs [ -v ] [ -io options ] path -i Ignores the options specified for a file system path in the /etc/exports file. If you do not specify the I option with the -o option, Data ONTAP uses the options specified for the file system path in the /etc/ exports file instead of the options you specify on the command line.

• Question 152:

  In an active/active configuration in takeover mode, the surviving controller interfaces will reflect the identity of the ________.

  A. local interfaces only
  B. failed partner interfaces only
  C. local and failed partner interfaces
  D. interfaces as defined in the /etc/rc file
  D. interfaces as defined in the /etc/rc file

  ---

  In takeover mode, this network interface assumes the identity of the network interface on the partner http:// www.wafl.co.uk/tag/ifconfig/#sthash.3rsjaDZD.dpuf For the partner interface configuration to be persistent across reboots, you must include the ifconfig command in the /etc/rc file http://hd.kvsconsulting.us/netappdoc/801docs/html/ontap/nag/GUID-525FCF4E-109D-4E6F-9256- C6E56438CA9A.html

• Question 153:

  In a Fibre Channel configuration, the host's HBA is referred to as the ___________, and the storage system's HBA is referred to as the __________ .

  A. initiator, target
  B. primary, secondary
  C. secondary, primary
  D. target, initiator
  A. initiator, target

• Question 154:

  After upgrading to DOT 8.07-mode, you can convert existing 32-bit aggregates into 64-bit aggregates.

  A. True
  B. False
  B. False

  ---

  http://www.ntapgeek.com/2011/12/how-in-place-expansion-works.html

  To upgrade an aggregate in-place, the only available method is to add disks to expand the aggregate to >16TB.

  There is an obscure method using diag mode but that is not supported or mentioned in the exam content. The answer is always add disks to grow past 16TB, or migrate.

• Question 155:

  What command would create a LUN clone named lun0.clone from the LUN lun0 on the volume vol2?

  A. lun clone start create /vol/vol2/lun0.clone -b /vol/vol2/lun0 snap_recent
  B. lun clone create /vol/vol2/lun0.clone -b /vol/vol2/lun0 snap_recent
  C. lun clone create /vol/vol2/lun0 -b /vol/vol2/lun0.clone snap_recent
  D. lun clone create /vol/vol2/lun0.clone -b /vol/vol2/lun0 -s snap_recent
  B. lun clone create /vol/vol2/lun0.clone -b /vol/vol2/lun0 snap_recent

• Question 156:

  Which option will allow a storage system to SnapMirror from this source system?

  A. snapmirror.access
  B. snapmirror.destination
  C. options snapmirror.allow host =
  D. options snapmirror.access host =
  D. options snapmirror.access host =

  ---

  The snapmirror.access option is the preferred method for controlling snapmirror access on a snapmirror source filer. http://www.wafl.co.uk/snapmirrorallow/#sthash.4Cb8IqqN.dpuf

• Question 157:

  Host multi-pathing describes a ____________ solution that has at least two distinct ______________ paths to a LUN.

  A. Token ring, physical
  B. FC SAN, virtual
  C. FC or IP SAN, virtual
  D. FC or IP SAN, Physical
  D. FC or IP SAN, Physical

  http://en.wikipedia.org/wiki/Multipath_I/O

  Fiber Channel (FC), FCoE and iSCSI encapsulate SCSI-3. FCoE and iSCSI further encapsulate the transport within IP; hence the term IP SAN.

  In computer storage, multipath I/O is a fault-tolerance and performance enhancement technique whereby there is more than one physical path between the CPU in a computer system and its mass storage devices through the buses,

  controllers, switches, and bridge devices connecting them.

  A simple example would be a SCSI disk connected to two SCSI controllers on the same computer or a disk connected to two Fibre Channel ports. Should one controller, port or switch fail, the operating system can route I/O through the

  remaining controller transparently to the application, with no changes visible to the applications, other than perhaps incremental latency.

• Question 158:

  Which three statements apply to NearStore Personality license? (Choose three.)

  A. It increases the storage capacity.
  B. It converts the destination storage system to a NearStore system.
  C. It requires the nearstore_option license on the destination storage system.
  D. It provides increased concurrent streams when the storage systems are used as destinations for SnapMirror and SnapVault transfers.
  B. It converts the destination storage system to a NearStore system.
  C. It requires the nearstore_option license on the destination storage system.
  D. It provides increased concurrent streams when the storage systems are used as destinations for SnapMirror and SnapVault transfers.

• Question 159:

  Which storage system command would display the WWPNs of hosts that have logged into storage system using a Fibre Channel connection?

  A. fcp config
  B. fcp initiator show
  C. fcp show i
  D. fcp show initiator
  D. fcp show initiator

  ---

  https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_fcp.1.html fcp show initiator [ -v ] [ adapter ]

  If no adapter name is given, information about all initiators connected to all adapters are shown. The command displays the portname of initiators that are currently logged in with the Fibre Channel target adapters. If the portname is in an

  initiator group setup through the igroup command, then the group name is also displayed. Similarly, all aliases set with the fcp wwpn-alias command for the portname are displayed as well.

  If the -v flag is given, the command displays the Fibre Channel host address and the nodename/portname of the initiators as well.

• Question 160:

  When replicating data between 32-bit and 64-bit aggregates, which two are allowed? (Choose two)

  A. NDMPcopy
  B. QSM
  C. vol copy
  D. VSM
  A. NDMPcopy
  B. QSM

  http://wafl.co.uk/ndmpcopy/

  Because volume SnapMirror works at the block level, the source and destination must both be FlexVol volumes in the same aggregate type. The source and destination of a volume SnapMirror relationship must either both be FlexVol

  volumes in 32-bit aggregates or both be FlexVol volumes in 64-bit aggregates. Therefore you cannot create a volume SnapMirror relationship from a FlexVol volume in a 32-bit aggregate to a FlexVol volume in a 64-bit aggregate or vice

  versa.
