Network Appliance NS0-194 問題集

質問 1：
You have a 4-node cluster configured for FC. You create a new LUN on node 1, map the LUN to a host, and verify that the host is able to correctly access the LUN. However, after moving the LUN's volume to node 3, ALUA reports that all the paths are non-optlmized. You have already verified that all zoning and physical cabling is correct.
What should you do to enable ALUA to see the optimized paths?
A. Update the igroup initiator WWPN.
B. Update the MPIO policy to most recently used.
C. Update the reporting nodes for the LUN mapping.
D. Update the MPIO policy to round-robin.
正解：C

質問 2：
A customer has one storage virtual machine (SVM) that is using Fibre Channel as a protocol (FCP). Some clients are successfully accessing LUNs on this SVM.
The zoning is done by using worldwide port names (WWPNs). The customer creates a second SVM for Fibre Channel and wants to access new LUNs in this SVM from the same clients.
Which three statements are true in this scenario? (Choose three.)
A. Fibre Channel zoning does not need to be changed if the second SVM uses the same ports as the first SVM.
B. FCP must be enabled on the second SVM.
C. Fibre Channel zoning must be reconfigured for the new SVM.
D. You must map the new LUNs in the second SVM to the correct initiator group (igroup).
E. The initiator groups (igroups) from the first SVM are also working for the second SVM.
正解：A,B,E

質問 3：
A customer observes write latencies above 40 ms on a clustered Data ONTAP system with two FAS3220s for a period of several minutes each night.
During performance analysis, you discover that several back-to-back CPs occur In this scenario, which two configuration changes will reduce the write latencies? (Choose two.)
A. Add more disks to the aggregate.
B. Add flash cache cards to the nodes.
C. Move the volume with the highest write load to an aggregate with faster disks.
D. Migrate the LIF with the highest network receive rate to a faster port.
正解：B,C

質問 4：
Which two conditions would prevent a normal giveback operation? (Choose two.)
A. The presence of a failed IOM module
B. The presence of failed disks
C. Connected NFsv3 sessions
D. Active SnapMirror transfer
正解：A,B

質問 5：
You are migrating volumes from an older aggregate to a new aggregate using the vol move command. You notice that, after completion, access to these volumes is slower until a certain process finishes.
Which process is causing the problem in this scenario?
A. deswizzling
B. active bitmap rearrangement
C. snap create
D. container block reclamation
正解：C

質問 6：
You want to map an iSCSI LUN from a NetApp controller.
Which two components are required to accomplish this task? (Choose two.)
A. initiator WWPN
B. igroup
C. iSCSI initiator
D. FCP zoning
正解：A,D

質問 7：
Which LIF role is used for SnapMirror traffic between two clusters?
A. ~cluster-mgmt~
B. ~intercluster~
C. ~data~
D. ~cluster~
正解：B

質問 8：
You are upgrading your FAS cluster to an AFF cluster. All the volumes have finished migrating to the AFF nodes. ALUA is working on all attached SAN clients. You now want to move the SAN LIFs to the AFF nodes without any SAN client disruption.
Working one LIF at a time, which three steps are required to perform this process? (Choose three.)
A. Add the SAN LIF to the portset.
B. Migrate the SAN LIF to the AFF.
C. Modify the SAN LIF to be home on the AFF.
D. Take the SAN LIF down.
E. Bring the SAN LIF up.
正解：C,D,E
