Question No : 1

You have an SVM that serves LUNs to your hosts in an FC SAN environment. This SVM runs on a 4-node cluster and has two data LIFs on each node, according to best practices. You just created a LUN and mapped it to your initiators group. The LUN is owned by node01.
In this scenario, what would be an appropriate test for LUN mobility?

A.Move the LUN to node02.
B.Mirror the LUN to another node in your cluster.
C.Physically disconnect the SAN ports, and verify if the SAN data LIFs automatically move to other hosts.
D.Copy the LUN to another node and create a new LUN map.

B.Create six distinct zones that include specific ports within each zone.
C.Zone target ports of source storage with initiator ports of destination storage.

Question No : 9

A 4-node ONTAP FAS9000 cluster was used to serve I/O from six RedHat 7.3 servers. The servers were configured with maximum, queue depth.
For production purposes, an additional 60 similarly configured hosts were added to the environment. Later, the hosts started reporting random QFull errors, and the aggregated performance degraded.
Which two solutions would alleviate the QFull errors and performance problems? (Choose two.)

A.Remove Selective LUN Mapping (SIM) from the 4-node FAS9000 cluster.
B.Download the latest FC HBA driver, firmware, and BIOS, and deploy them on the hosts.
C.Configure and use additional FC target HBAs in the FAS9000 cluster.
D.Reduce FC HBA gueue depth on the hosts.

정답:

Question No : 10

A company has 20 ESX hosts. Ten of the hosts are connected using FC, and the rest are connected over iSCSI. The FC host HBA queue depth is set to 32, and the iSCSI LUN queue depth is set to 64. The FC hosts are now experiencing random connectivity issues.
In this scenario, what would be the reason for the disconnects?

A.The FC host has a lower queue depth.
B.According to the IMT, unsupported HBA firmware is in use.
C.All of the hosts are part of the same cluster.
D.The queue depth is not consistent across the cluster.

Question No : 13

You need to configure iSCSI on your existing ONTAP cluster in a new SVM. The iSCSI LUNs will be served over a new Layer 2 network using the same physical ports that also use the CIFS protocol on a different SVM.

A.Create a new portset.
B.Create a new VLA
C.Create a new broadcast domain.
D.Create a new AD object.
