QUESTION 78
When using SnapRestore to restore a single LUN, the LUN must be ____.
A. exported and accessible
B. mapped to a Windows server
C. mounted on a host
D. taken offline or unmapped
Answer: D
Explanation:
https://library.netapp.com/ecmdocs/ECMP1196995/html/GUID-577EDC41-FEA0-4987-8F04-55E736962FD1.html
Always unmount the LUN before you run the snap restore command on a volume containing the LUN or before you run a single file SnapRestore of the LUN. For a single file SnapRestore, you must also take the LUN offline.
QUESTION 79
For aggregates or traditional volume SyncMirror to work correctly, the configuration of each plex should be identical with regard to ____.
A. NVRAM
B. Mirrored Snapshot copies
C. RAID groups and disk sizes
D. NDMP and Snapshot copies
Answer: C
Explanation:
SyncMirror is essentially a RAID-1 mirror; hence the name. The best practice is to mirror storage of equal performance; i.e. identical RAID groups and disk sizes (number of spindles, IOPS). If you were to mirror two storage devices of different performance, the slower device would be the limiting factor.
QUESTION 80
What happens when two aggregates are rejoined?
A. It is not possible to rejoin aggregates.
B. Data ONTAP will always retain data from the newest aggregate.
C. Both aggregates revert to the last common snapshot before the split.
D. You will have a large new aggregate containing all volumes from both aggregates.
E. One of the aggregates will be overwritten and you will lose any data changed on it after the split.
Answer: E
Explanation:
When you rejoin split aggregates, Data ONTAP mirrors the data from one aggregate to the other and destroys data that existed on that aggregate before the rejoin.

QUESTION 81
You cannot remove the SyncMirror license if one or more mirrored volumes exist.
A. True
B. False
Answer: A
Explanation:
You cannot disable the SyncMirror license if mirrored aggregates exist and are online.

QUESTION 82
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. halt all operations to volumes in that pool
B. choose spare disks to reconstruct from the opposite pool
C. warn you that there are no available spares from the proper pool
D. “halt” after 24 hours if spare disks are not added to the proper pool
Answer: C
Explanation:
Both `warn you that there are no available spares from the proper pool’ and `halt after 24 hours if spare disk are not added to the proper pool’ are correct answers. However, since Data ONTAP alerts you first, ‘warn you that there are no available spares’ is the best answer.

QUESTION 83
The required hardware to add SyncMirror to an existing system would be ____.
A. disk shelves and cluster interconnect
B. disk shelves and termination switches
C. disk shelves, Ethernet adapters, and cabling
D. disk shelves, Fibre Channel adapters, and cabling
Answer: D
QUESTION 84
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.
Answer: CD
Explanation:
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 85
After issuing the aggr split aggr0/plex0 aggrNew command ____.
A. there is a new plex called aggrNew
B. there are two new plexes, plex0 and plexNew
C. there is a new mirrored aggregate called aggrNew
D. there are two unmirrored aggregates, aggr0 and aggrNew
E. flexible volumes are evenly split between aggr0 and aggrNew
Answer: D

Answer: C
Explanation:
Ensure that both plexes of the mirrored aggregate you are splitting are online and operational.

A. in a giveback mode
B. fenced off manually
C. powered on and accessible
D. powered off and inaccessible

You have connected all cables and disk shelves in a fabric-attached MetroCluster. Which command would verify that disks are connected and have dual paths?
A. disk show
B. sysconfig -p
C. vol status -r
D. storage show disk -p
Answer: D
Explanation:
The operator must ensure that the partner filer does not become operational at any time while a filer is in a takeover mode initiated by the use of this command.

QUESTION 89
When using MetroCluster in a forced takeover mode, identify two methods for restricting access to the disaster site node. (Choose two.)
A. Use manual fencing.
B. Use the cf giveback -f command.
C. Use the cf forcetakeover -d command.
D. Turn off power to the disaster site node.
E. Isolate the failed node from the surviving node.
