QUESTION 41

What does it signify if the disks are “not owned” in a FAS2020 system?

 

A.

The disks are mailbox disks.

B.

The disks are spare disks.

C.

The disks are data disks.

The disks are not used.

 

Correct Answer: D

Explanation:

Disks must be assigned to an aggregate to be used as raid group members or spares.

Unassigned disks aredisplayed as “not owned”.

QUESTION 42

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

 

Correct Answer: D

Explanation:

6979/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 targetadapters. If the portname is in an initiator group setup through the igroup command, then the group name isalso displayed. Similarly, all aliases set with the fcp wwpn-alias command for the portname are displayed aswell.

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

 

 

QUESTION 43

To configure a storage system as a member of a Windows active directory domain, the time on the storage system must be set to be within plus or minus five minutes of the time on the domain controller.

 

A.

True

B.

False

 

Correct Answer: A

 

 

QUESTION 44

What are three true statements about physical reallocation of data added in ONTAP 7.3? (Choose three.)

 

A.

Use reallocate -p pathname to run the physical reallocate.

B.

Use aggr reallocate -p pathname to run the physical reallocate.

C.

Reinitialize any SnapMirror relationship for the new physical geometry.

D.

Volume Snapshots do not need to be deleted for the reallocate to run effectively.

E.

Dont run it on files, volumes, and LUNs that are in an aggregate created by a version of ONTAP earlier than 7.2.

 

Correct Answer: ADE

Explanation:

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

 

The -p option requests that reallocation of user data take place on the physical blocks in the aggregate, but thelogical block locations within a flexible volume are preserved. Aggregate reallocation is not supported on aggregates created prior to Data ONTAP 7.2. Using the -p option may reduce the extra storage requirements in a flexible volume when reallocation is run ona volume with snapshots. It may also reduce the amount of data that needs to be transmitted by SnapMirror onits next update after reallocation is performed on a SnapMirror source volume.

 

 

QUESTION 45

An iSCSI or FC SAN implementation provides ____________ access to LUNs.

 

A.

VLD

B.

VIIP

C.

File

D.

Block

 

Correct Answer: D

Explanation:

iSCSI and Fiber Channel encapsulate SCSI protocol, simulating direct disk access. These are commonlyreferred to as a block storage protocols. FCoE is another such protocol. CIFS and NFS, HTTP and FTP provide file access not block access.

 

 

QUESTION 46

Which three licenses are required for fabric-attached MetroCluster? (Choose three.)

 

A.

Cluster

B.

Cluster_remote

C.

Syncmirror_local

D.

Syncmirror_fabric

E.

Syncmirror_remote

 

Correct Answer: ABC

Explanation:

http://backdrift.org/man/netapp/man1/na_license.1.html

In preparation for a fabric attached metrocluster configuration, the following licenses must be installed:

Clustersyncmirror _local

cluster_remote

syncmirror_fabric and syncmirror_remote are not valid license types.

 

 

QUESTION 47

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

 

A.

exportfs -v <;pat>;

B.

exportfs -u <path>

C.

exportfs -a <path>

D.

exportfs -i <;pat>;

 

Correct Answer: D

Explanation:

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-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 48

Which two operations can be performed with the SnapDrive for windows graphical user interface?

 

A.

Create volume

B.

Create Snapshot copies

C.

Create File

D.

Create Disk

 

Correct Answer: BD

What SnapDrive does

SnapDrive software integrates with the Windows Volume Manager so that NetApp filers can serve as virtualstorage devices for application data in Windows 2000 Server and Windows Server 2003 environments.

 

SnapDrive is dependent on the virtual disk service. The virtual disk service must be started on the host prior toinstalling SnapDrive. SnapDrive manages virtual disks (LUNs) on a NetApp filer, making these virtual disksavailable as local disks on Windows hosts. This allows Windows hosts tointeract with the virtual disks just as if they belonged to a directly attached redundant array of independentdisks (RAID).

 

SnapDrive provides the following additional features:

It enables online storage configuration, virtual disk expansion, and streamlined management.

It integrates NetApp Snapshot technology, which creates point-in-time images of data stored on virtualdisks.

It works in conjunction with SnapMirror?software to facilitate disaster recovery from either asynchronouslyor synchronously mirrored destination volumes.

 

 

QUESTION 49

When running deduplication on SnapVault destinations, which three statements are true?

 

A.

The target SnapVault controller deduplicates inline.

B.

The source SnapVault data is deduplicated inline on the target before it is written to disk.

C.

Deduplication internally synchronizes with the SnapVault schedule on the destination.

D.

The source (primary) system sends duplicated data even if the source data is deduplicated.

E.

Deduplication with SnapVault creates a snapshot, deduplicates, then deletes and recreates the snapshot toeffectively deduplicate savings.

 

Correct Answer: CDE

Explanation:

https://library.netapp.com/ecmdocs/ECMP1196986/html/GUID-E5AD37DE-2F44-47DB-90A3-C8E115FCBFB7.html

SnapVault replicates at the file level not the block level. Deduplication is always a post-processed activity for Data OnTap, while compression is an inline process.

The deduplication schedule depends on the SnapVault update schedule on the destination system.

A new Snapshot copy replaces the archival Snapshot copy after deduplication finishes running on thedestination system. (The name of this new Snapshot copy is the same as that of the archival copy, but theSnapshot copy uses a new timestamp, which is the creation time.)

The SnapVault update recognizes the deduplicated blocks as changed blocks. Thus, when deduplication is runon an existing SnapVault source for the first time, all saved space is transferred to the destination system.

 

 

QUESTION 50

Which three protocols can coexist on a NetApp storage system? (Choose three)

 

A.

DAFS

B.

CIFS

C.

DFS

D.

FCP

E.

NFS

 

Correct Answer: BDE

Explanation:

Data OnTap can simultaneously serve NAS and SAN protocols. CIFS, NFS, and FC protocol are examples ofNAS and SAN protocols respectively.

 

Data OnTap 7.1 or later does not support DAFS.

DFS provides location transparency and redundancy by allowing shares in multiple different locations to belogically grouped under one folder, or DFS root. While practically a CIFS server shared by a Data OnTap filercan be a DFS target, DFS namespaces can only be hosted on Windows systems.
