Answer: C
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
A mirrored volume, volX, is composed of twelve 36-Gigabyte disks: six in volX/plex0, six in
volX/plex1. A drive fails in plex1, but pool 1 contains only 72-Gigabyte spare disks.
Data ONTAP will do which of the following?
A. Choose a 72-Gigabyte disk and downsize it
B. Halt after 24 hours of running in degraded mode
C. Alert you that there are no 36-Gigabyte disks and wait for one to be inserted
D. Stop any applications that are running
Answer: A
Please click the exhibit button.
In this example, volX contains three 36-Gigabyte disk drives. To create a mirror for volX, you
issue the command to create the mirror: vol mirror volX.
You immediately realize that the disks used to create the mirror are 72 Gigabytes in size. You
want to take the plex offline and destroy it. You enter the vol status -r command and it displays
the output shown in the exhibit.
To successfully take volX/plex1 offline and destroy it, which of the following must be done?
A. Reboot the storage appliance.
B. Wait for the "resyncing"operation to complete.
C. Take volX/plex1 offline and split it off.
D. Rename volX/plex1.
Answer: B
Select the parameter for which the Cluster Configuration Checker does NOT test.
A. Mismatched option settings
B. Network interface configuration errors
C. Different versions of Data ONTAP on the local and partner nodes
D. Open firmware versions
Answer: D
You are troubleshooting a clustered failover problem at a customer site. The customer explains
that both storage appliances were NFS mounted onto the Solaris host. You attempt to create a
file on the NFS mount point for the inaccessible appliance, but you get the following error:
NFS server filer2 not responding still trying.
Symptoms:
1) When not in takeover mode, both storage appliances operate normally.
2) In takeover mode, the taken over node is not accessible on the network.
You perform a"cf giveback" and you can now create a file over NFS on both appliances. What
should you do first to resolve this issue?
A. Replace the cluster interconnect card and run diagnostics "all"to ensure proper system
operation.
B. Replace the NIC adapter.
C. Use the cluster-config-checker.cgi to identify the problem and corrective action.
D. Submit a new bug report.
Answer: C
Which of the following commands would you issue to perform a "clean" shutdown of a clustered
system without allowing takeover to occur?
A. halt
B. halt -f
C. halt -d
D. sys-shutdown
Answer: B
A storage appliance in a clustered configuration can's access its partner's mailbox disks. When
you enter the cf status command, you see the following:
filer2> cf status filer1 is up, takeover disabled because of reason (partner mailbox disks not
accessible or invalid)
What should you check first to resolve this issue?
A. Check volumes of all disks
B. Check NIC adapter
C. Check that initiator is set to "target"mode
D. Check for disk viability or FC-AL problems
Answer: D
Both appliances in a clustered configuration must have _______.
A. one cluster license only
B. a special set of licenses to allow takeover
C. SyncMirror licenses
D. the same license(s)

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 1's disk shelves.
Which 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
B. Negotiated Fail Over
C. Auto enable of giveback
D. cf.quickloop.enable
Answer: B
To remove a cluster setup, you must perform the following steps.

2. Unlicense cluster.
3. Remove partner entries for network interfaces from the /etc/rc file.
4. Halt and make sure the partner-sysid is blank.
5. Power down and remove the cluster interconnect card.
6. Perform steps 1-5 above on the partner node.
A. True
B. False
