NS0-163 Network Appliance Data Protection Solutions Part 2

http://www.aroopam.com/NetApp X1024 Fibre Channel HBA is required on the storage systems for IP over Fibre Channel functionality. A. True B. False Answer: A In a synchronous SnapMirror configuration, the source storage appliance exhibits high http://http://aroopam.com latency due to user traffic and rapid data change from SnapMirror transactions. Which one of the following tuning methods best resolves this performance behavior? Edit the /etc/snapmirror.conf file on the destination storage appliance and set: A. outstanding=3s B. visibility_interval=3s C. cksum=3s D. src con=3 Answer: A What does it signify if the disks are "not owned" in a FAS270C appliance? A. The disks are data disks. B. The disks are spare disks. C. The disks are mailbox disks. D. The disks are not used. Answer: D When you are setting up SnapMirror, which one of the following is not a replication pre- requisite? A. SnapMirror must be licensed for each storage appliance. B. The source volume must be offline. C. If you are replicating a volume, you must create a restricted volume to be used as theSnapMirror destination volume. D. The capacity of theSnapMirror destination must be greater than or equal to the capacity of the source. Answer: B Which three are true when creating a SyncMirror volume? (Choose 3) http://http://aroopam.com A. The number of disks added must be an even number and equally divided between the twoplexes. B. The disks selected forPlex 0 and Plex 1 must come from the same disk pools. C. The number of disks selected for oneplex must equal the number of disks selected from the other plex. 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 downsizes it. Answer: A,C,D For a configuration change to be effective when using the OSSV configurator, the OSSV service must be restarted. A. True B. False Answer: A For a configuration change to be effective when using the OSSV configurator, the OSSV service must be restarted. A. True B. False Answer: A Which command displays the disk ownership for both CPU modules in a FAS270C appliance? A. disk show-v B. disk display-r C. disk own -s D. vol status -r http://http://aroopam.com Answer: A In a Fabric Attached MetroCluster, a "disaster" is described as a: A. Failure of the Inter-Switch-Links (ISL) B. Malfunction of the Fiber Channel adapter on the cluster node C. Failure of the interconnect cable D. Prolonged communication disruption Answer: D A mirrored volume has a failed disk, but there are no available spares in the pool from which the degraded plex was built. Data ONTAP will: A. Choose spare disks to reconstruct from the opposite pool B. Warn you that there are no available spares from the proper pool C. "Halt" after 24 hours if spare disks are not added to the proper pool D. Stop all applications that are running Answer: B Which one of the following commands would you use to disable client access to snapshots on a volume called /vol/flexvoM? A. vol options/vol/flexvoM nosnapdiroff B. vol options/vol/flexvoM nosnapdiron C. vol options/vol/flexvoM snapdiroff D. vol options/vol/flexvoM snapdiron Answer: B http://http://aroopam.com What user-controllable security mechanism is built into OSSV? A. QSM access list modifiable viasvconfigurator B. Contents inside a file called access and located in OSSV /snapvault/etc C. Via/etc/hosts.equiv file D. MD5 based authentication betweenSnapVault primary and secondary, with changeable password Answer: A Data ONTAP uses inodes in an active file system to reference__________________. A. disk blocks B. file segments C. qtrees D. snapshots Answer: A Which two of the following NetApp storage appliances do not support the use of synchronous SnapMirror? A. F825 B. FAS960 C. F87 D. F820 Answer: C,D Which two of the following statements apply to the fs_size_fixed volume option? A. The default setting is on B. This option is automatically set to be on when a volume becomes a Snap Mirrored volume http://http://aroopam.com C. This option causes the file system to remain the same size and not grow or shrink when a Snap Mirrored volume relationship is broken D. The option turns to off after thesnapmirror break command is issued for the volume Answer: B,C Which one of the following statements apply to Advanced Single Instance Storage (ASIS)? A. Eliminates duplicates files inSnapVault for NetBackup secondary volumes B. Eliminates duplicates blocks inSnapVaultfor NetBackup source volumes C. Eliminates duplicates blocks inSnapVault for NetBackup secondary volumes D. Eliminates duplicates files inSnapVaultfor NetBackup source volumes Correct answers Answer: C Which one of the following statements does not apply to the SnapMirror visibility- interval variable? A. This variable controls the view of the data on the destination system B. By setting a value, you specify the amount of time before an automatic snapshot is created on the source volume that is synchronously mirrored C. The default interval value is 5 minutes D. The smallest interval value supported is 30 seconds Answer: C Node 1 in a clustered pair detects that it has lost connectivity to one of its disk shelves. Node 1 is still up, but it cannot see one of its disk shelves. However, the partner node, Node 2, can see all of Node 1s disk shelves. Which one of the following features will cause Node 2 to monitor this error condition for a period of three minutes (by default), and then forcibly take over Node 1 if the error condition persists? A. Takeover on panic 34 http://http://aroopam.com http://http://aroopam.com B. Negotiated Fail Over C. Auto enable of giveback D. cf.quickloop.enable Answer: B
