NetApp NS0-155 Online Practice Questions and Exam Preparation

NetApp NS0-155 Online Questions & Answers

• Question 51:

  You are having problems accessing three recently-created LUNs. Given the output below, the reason is because all of the LUNs are using the same LUN ID of 0.

  lun show -m LUN pathMapped to LUNID

  /vol/vol1/lun0 solaris-igroup0 0 /vol/vol1/lun1 windows-igroup 0 /vol/vol1/qtree1/lun2 aix-igroup 0 /vol/vol1/qtree1/lun3 linux-igroup 0

  A. True
  B. False
  B. False

  ---

  The 'lun' in the path is irrelevant. The 0 at the end of each statement denotes the LUN ID. LUN IDs must be unique per igroup.

• Question 52:

  Which three tools present statistics from the Data ONTAP counter manager? (Choose three)

  A. Operations manager
  B. Window perfmon
  C. Sysstat
  D. Stats
  A. Operations manager
  B. Window perfmon
  D. Stats

• Question 53:

  There are three phases of Non Disruptive Volume Movement (NDVM). What is the correct sequence of these phases?

  A. Setup Phase, Mirror Phase, Cutover Phase
  B. Initialization phase, Copy Phase, Migrate Phase
  C. Begin Phase, Move Phase, Complete Phase
  D. Setup Phase, Data Copy Phase, Cutover Phase
  D. Setup Phase, Data Copy Phase, Cutover Phase

  Non-disruptive Volume Movement is called DataMotion. DataMotion uses SnapMirror for volume migration. A DataMotion migration occurs in three phases:

  1.

  Setup

  2.

  Data copy

  3.

  Cutover

• Question 54:

  If you believe you create FC SAN performance problem, which NatApp utility would gather both your Solaris host and storage system data for analysis?

  A. sio_ntap.exe
  B. prestart
  C. poststat
  D. perfstat
  D. perfstat

  Performance and Statistics Collector (perfstat) is a data collection tool with several key properties:

  Captures all needed performance information with one command Captures information from host(s) and filer(s)

  Captures all information simultaneously for cross correlation Operates on all host platforms and all filer platforms

  All captured data is recorded in a single plain-text output file

  Perfstat comes in exactly two flavors:

  Unix/Linux version (perfstat.sh) Windows version (perfstat.exe)

  Supported platforms: Unix: AIX, HP-UX, Linux, OSF1, Solaris, FreeBSD Windows: 2000/XP/2003

• Question 55:

  Which three are valid LUN commands? (Choose three)

  A. lun clone
  B. lun copy
  C. lun move
  D. lun rename
  E. lun snap
  A. lun clone
  C. lun move
  E. lun snap

  The following commands are available in the lun suite:

  

• Question 56:

  Which is true of the SnapVault backup of a NetApp storage system?

  A. The file is the basic unit for SnapVault backup destination.
  B. The qtree is the basic unit for SnapVault backup destination.
  C. The volume is the basic unit of SnapVault backup destination.
  D. The directory is the basic unit for SnapVault backup destination.
  B. The qtree is the basic unit for SnapVault backup destination.

  The data structures that are backed up and restored through SnapVault depend on the primary system. On systems running Data ONTAP, the qtree is the basic unit of SnapVault backup and restore. SnapVault backs up specified qtrees on the primary system to associated qtrees on the SnapVault secondary system. If necessary, data is restored from the secondary qtrees back to their associated primary qtrees. On open systems storage platforms, the directory is the basic unit of SnapVault backup. SnapVault backs up specified directories from the native system to specified qtrees in the SnapVault secondary system.

  If necessary SnapVault can restore an entire directory or a specified file to the open systems platform. The destination system uses a slightly more disk space and directories than the source system.

• Question 57:

  Which Data ONTAP option sets system-wide throttling for all transfers?

  A. options transfer.wide.enable
  B. options transfer.throttle.enable
  C. options replication.wide.enable
  D. options replication.throttle.enable
  D. options replication.throttle.enable

• Question 58:

  Data ONTAP 8.0 7-Mode supports SMB 2.0 in Windows Vista and Windows Server 2008.

  A. True
  B. False
  B. False

  http://www.netapp.com/us/system/pdf-reader.aspx?m=tr-3740.pdfandcc=us SMB 2.0 support was included in Data OnTap 8.1.

• Question 59:

  Which three FAS deduplication features exist in ONTAP 8.0 7-Mode?

  A. The deduplication fingerprint and change logs were moved to the root volume /etc/dedup directory.
  B. After breaking the deduplication volume destination mirror, the deduplication (a-sis) process continues uninterrupted.
  C. Qtree SnapMirror is supported on the destination for deduplication by enabling on the source, destination, or both systems.
  D. The fingerprint database and the change logs that the deduplication process uses are located outside the volume, in the aggregate.
  E. The deduplication schedule is not tied to a Qtree SnapMirror update, and can be configured just like the deduplication schedule for any volume.
  C. Qtree SnapMirror is supported on the destination for deduplication by enabling on the source, destination, or both systems.
  D. The fingerprint database and the change logs that the deduplication process uses are located outside the volume, in the aggregate.
  E. The deduplication schedule is not tied to a Qtree SnapMirror update, and can be configured just like the deduplication schedule for any volume.

  Section: Data Protection NetApp also recommends that if deduplication is used on the source volume, then it should also be used on the destination volume. However, you are not restricted using deduplication on the source volume only. The deduplication schedule is not tied to the qtree SnapMirror update. In other words, the deduplication process does not automatically start at the completion of the qtree SnapMirror transfer. The fingerprint database and the change log files that are used in the deduplication process are located outside of the volume in the aggregate and are therefore not captured in Snapshot copies http://www.netapp.com/us/ media/tr-3505.pdf

• Question 60:

  To determine the version of Data ONTAP in which a bug has been fixed, use the NOW site _______ utility. (Choose two.)

  A. AutoSupport
  B. Bugs Online
  C. NetApp Diagnostics
  D. Release Comparison
  E. System Configuration Guide
  B. Bugs Online
  D. Release Comparison

  ---

  This question is out of date, but its still on the exam as of Sept2013! NOW has been replaced with support.netapp.com.

  You should be very familiar with what AutoSupport does. Also if you have done any research, you know that the System Configuration Guide is an invaluable tool that you will use regularly. Neither of those are related to bugs.

  Bugs Online (BOL) is located at http://support.netapp.com/NOW/cgi-bin/bol/ Bugs Online provides a suite of tools to help manage and resolve your bug issues.

  The Release Bug Advisor is located at

  http://support.netapp.com/NOW/cgi-bin/relrec

  There is also a Version Comparison tool available at
