  Flash Cache is a controller-attached PCIe intelligent caching solution.

  Flash Accel is a host-attached caching solution.

  Flash Pool utilizes SSDs to enhance performance of disk aggregates (implicitly not controller-wide).

  Flash Disk and Flash IO are ambiguous terms.

• Question 72:

  Which command displays the disk ownership for both CPU modules in a FAS2020 system?

  A. disk own -s
  B. disk show -v
  C. vol status -r
  D. disk display r
  B. disk show -v

  ---

  disk show [ -o | -s | -n | -v | -a]

  Used to display information about the ownership of the disks. Available only on systems with software- based disk ownership. -o lists all disks owned by the filer with the name -s lists all disks owned by the filer with the serial number -n lists all unassigned disks. -v lists all disks. -a lists all assigned disks.

• Question 73:

  Which two are true when creating a SyncMirror volume? (Choose two.)

  A. The disks selected for Plex 0 and Plex 1 must come from the same disk shelf.
  B. The disks selected for Plex 0 and Plex 1 must come from the same disk pools.
  C. The number of disks added must be an even number and equally divided between the two plexes.
  D. The disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the size of the disk. If there is no equivalent-sized disk, Data ONTAP takes a larger capacity disk and right-sizes it.
  C. The number of disks added must be an even number and equally divided between the two plexes.
  D. The disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the size of the disk. If there is no equivalent-sized disk, Data ONTAP takes a larger capacity disk and right-sizes it.

  ---

  The rules for the selection of disks or array LUNs, for using as mirrored aggregates, are as follows:

  Disks or array LUNs selected for each plex must be in different pools. The same number of disks or array LUNs must be in both the plexes. Disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the

  size of the disk.

  If there is no equivalent-sized disk, Data ONTAP uses a larger-capacity disk, and limits the size to make it identically sized.

  Data ONTAP names the plexes of the mirrored aggregate.

• Question 74:

  What utility on the storage system will allow you to capture network packet information?

  A. Snoop
  B. Netstats
  C. Pktt
  D. Traceroute
  C. Pktt

  ---

  The pktt command controls a simple on-filer packet tracing facility. Packets can be captured into a trace buffer then dumped to a file, or the captured data can be logged to a file. The data is stored in "tcpdump" format, and can be directly viewed with tcpdump, ethereal, and perhaps other viewers. The output can also be converted using the editcap(1) program to a variety of other formats, including Sniffer, NetMon, and snoop.

• Question 75:

  Which command will show the FCP target(s) on a storage system?

  A. fcp show adapter
  B. fcp show all
  C. fcp show -t
  D. fcp status
  A. fcp show adapter

  ---

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

  fcp show adapter [ -v ] [ adapter ]

  If no adapter name is given, information about all adapters are shown. This command displays information such as nodename/portname and link state about the adapter. If the -v flag is given, this command displays additional information

  about the adapters.

• Question 76:

  When troubleshooting a double disk failure with SyncMirror, you decide to remove and destroy a plex from a mirrored aggregate. What steps remove a plex from a mirrored aggregate?

  A. Take the aggregate offline and use the aggr destroy command
  B. Take the aggregate offline and use the destroy -f command
  C. Ensure the plex is online and use the aggr destroy plexname command.
  D. Ensure the plex is offline and use the aggr destroy plexname command.
  D. Ensure the plex is offline and use the aggr destroy plexname command.

  https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_aggr.1.html

  aggr destroy { aggrname | plexname } [ -f ]

  Destroys the aggregate named aggrname, or the plex named plexname. Note that if the specified aggregate is tied to a traditional volume, then the traditional volume itself is destroyed as well. If an aggregate is specified, all plexes in the

  aggregate are destroyed. The named aggregate must also not contain any flexible volumes, regardless of their mount state (online, restricted, or offline). If a plex is specified, the plex is destroyed, leaving an unmirrored aggregate or

  traditional volume containing the remaining plex.

  Before destroying the aggregate, traditional volume or plex, the user is prompted to confirm the operation. The -f flag can be used to destroy an aggregate, traditional volume or plex without prompting the user.

  The disks originally in the destroyed object become spare disks. Only offline aggregates, traditional volumes and plexes can be destroyed.

• Question 77:

  A volume is SnapMirrored hourly. You revert the volume using a snapshot that was created two days ago. Which command continues the relationship?

  A. SnapMirror initialize
  B. SnapMirror quiesce
  C. SnapMirror resume
  D. SnapMirror resync
  E. SnapMirror update
  D. SnapMirror resync

  ---

  You can use the snapmirror resync command to reestablish the connection between the source and the destination. This command is applied after the SnapMirror relationship between the source and destination is broken. https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-5D846D24-0903-4982-A429- 71AE5C0F9033.html

• Question 78:

  Which objects can be restored by a single SnapRestore command? (Choose three)

  A. file
  B. LUN
  C. qtree
  D. volume
  E. directory
  A. file
  B. LUN
  D. volume

  ---

  SnapRestore on a file and volume: https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-1E99ACB2-5C69-4FFC-B115- 9D2951D109E9.html

  SnapRestore on a LUN: https://library.netapp.com/ecmdocs/ECMP1196995/html/GUID-577EDC41-FEA0-4987-8F04- 55E736962FD1.html

  Hint: snaprestore at the volume level or at the file level. LUNs are effectively files.

• Question 79:

  In Data ONTAP, both the Microsoft Windows Administrator and root are exempt from user and group quotas, but not from tree quotas.

  A. True
  B. False
  A. True

  ---

  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.

• Question 80:

  The snapvault update command is only available on the secondary system.

  A. True
  B. False
  A. True

  ---

  https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapvault.1.html snapvault update [ -k n ] [ -s snapname ] [ -w ] sec_ondary_qtree Available on the secondary only. Immediately starts an update of the specified qtree on the secondary.
