QUESTION 111
To manage SnapVault relationships with an NDMP management application, you must specify a:
A. directory path
B. volume and qtree
C. SnapVault license
D. username and password
Answer: D
Explanation:
Add a new backup user to the Backup Operators useradmin group list. Enter the following command:
useradmin user add backupuser -g “Backup Operators”
Generate an NDMP password for the new user.
Enter the following command:
ndmpd password backupuser
The NDMP password is used to authenticate the NetBackup media server to the storage system. This password is required for setup on the NetBackup management station. https://library.netapp.com/ecmdocs/ECMM1278284/html/onlinebk/5snapv37.htm
QUESTION 112
For OSSV sources, the qtree is the basic unit of SnapVault backups.
A. True
B. False
Answer: B
Explanation:

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 113
How can you “throttle” SnapValue updates and baseline transfers so that the primary or secondary is not transmitting data as it can?
A. Use the -k option in the snapvault start or snapshot modify commands.
B. SnapVault does not support throttling of network throughout.
C. Use the snapvault throttle command.
D. Use the -k option in the snapvault initialize command.
Answer: A
QUESTION 114
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 the Node 1’s disk shelves. Which feature 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. Auto enable of giveback
B. Negotiated Fail Over
C. Takeover on panic
D. Cf.quickloop.enable
Answer: B
Explanation:
http://www.wafl.co.uk/cf/
http://wafl.co.uk/options/
Negotiated failover is a general facility which supports negotiated failover on the basis of decisions made by various modules.
cf.takeover.on_disk_shelf_miscompare
This option allows negotiated takeover to be enabled when the cluster nodes detect a mismatch in disk shelf count. By default, this option is set to off.
This option is available only when cluster is licensed and changing the value on one filer automatically changes the value on the partner filer.
QUESTION 115
In Data ONTAP, the root user is exempt from those two quotas: ______________. (Choose two)
A. User quotas
B. Tree quotas
C. Root quotas
D. Group quotas
E. File quotas
Answer: AD
Explanation:
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 116
Which two Volume SnapMirror (VSM) relationship are supported? (Choose two)
A. Data ONTAP 8.0.2 64-bit –>Data ONTAP 8.1 64-bit
B. Data ONTAP 8.0.2 32-bit –> Data ONTAP 8.0.2 64-bit
C. Data ONTAP 7.3.2 32-bit –> Data ONTAP 8.1 64-bit
D. Data ONTAP 7.3.2 32-bit –> Data ONTAP 8.0.2 64-bit
Answer: AC
Explanation:
Volume SnapMirror Interoperability Matrix.
Reference: SnappMirror Async Overview and Best Practices guide.
QUESTION 117
An aggregate is composed of twelve 36-Gigabyte disks. A drive fails and only 72-Gigabyte spare disks are available. Data ONTAP will then perform what action.
A. Chooses a 72-Gigabyte disk and use it as is.
B. Chooses a 72-Gigabyte disk and right-size it.
C. Halts after 24 hour of running in degraded mode.
D. Alerts you that there are no 36-Gigabyte disks and wait for one to be inserted.
Answer: B
Explanation:
https://library.netapp.com/ecmdocs/ECMP1196986/html/GUID-8A91F6A2-61B8-42C3- AEAB7D5AA9BBE9CF.html
If a disk fails and no hot spare disk that exactly matches the failed disk is available, Data ONTAP uses the best available spare. Understanding how Data ONTAP chooses an appropriate spare when there is no matching spare enables you to optimize your spare allocation for your environment.
Data ONTAP picks a non-matching hot spare based on the following criteria (and more; in the link above):
If the available hot spares are not the correct size, Data ONTAP uses one that is the next size up, if there is one.
The replacement disk is downsized (aka right sized) to match the size of the disk it is replacing; the extra capacity is not available.
QUESTION 118
Which statement is true about expanding an aggregate from 32-bit to 64-bit in place?
A. All aggregates are automatically converted from 32-bit to 64-bit with the Data ONTAP 8.1 upgrade.
B. The expansion is triggered by an aggr convert command.
C. The expansion is triggered by adding disks to exceed 16 TB.
D. The 32-bit aggregates are degraded and must be Volume SnapMirrored to a new 64-bit aggregates
with Data ONTAP 8.1 upgrade.
Answer: C
Explanation:
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.
QUESTION 119
What utility on the storage system will allow you to capture network packet information?
A. Snoop
B. Netstats
C. Pktt
D. Traceroute
Answer: C
Explanation:
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 120
The root admin on the UNIX box receives an “Access Denied” message when he attempts to access a newly mounted qtree. What’s the most likely cause of this error?
A. The qtree is missing from the /etc/hosts file.
B. NFS is turned off on the storage system.
C. The qtree is set to ntfs security style.
D. The qtree has not been exported.
Answer: C
Explanation:
http://hd.kvsconsulting.us/netappdoc/801docs/html/ontap/smg/GUID-866DD79D-D2A6-4FBA- B0BDA63560FECEFF.html
https://library.netapp.com/ecmdocs/ECMP1196891/html/GUID-F6304830-B124-40A5-95D6- C646AA85E9E0.html
Only hostnames and IPs are referenced in /etc/hosts, so A is incorrect. The question states that the qtree was mounted, and B and D would preclude this so they are incorrect. You need to set a qtree to mixed or unix security style to support UNIX users.
QUESTION 121
Which two modes support using SnapMirror over multiple network paths?
A. Standalone
B. Partner
C. Multi
D. Failover
E. Give back
Answer: CD
Explanation:
https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-75BD4540-A103-4E2B-8B0A- E6BBC0D3F43F.html
http://backdrift.org/man/netapp/man5/na_snapmirror.conf.5.html
Two multipath methods are supported:
The multiplexing mode causes snapmirror to use both paths at the same time. If one should fail, it will switch to use the remaining path only and use both again should the failing path be repaired. Failover mode causes snapmirror to use the first path as the desired path and only use the second path should problems arise with the first path.
