  "Scenarios that cause a LIF failover

  LIF failover occurs in scenarios such as port failure, network interface failure, or cable failure. LIFs can be associated with failover rules that enable you to reroute the network traffic to other available ports in the cluster.

  LIF failover occurs in the following scenarios:

  When there is a power failure

  When automatic revert is enabled on a LIF and that LIF's home port reverts to the administrative up status

  The LIF automatically migrates back to the home port.

  When the port hosting a LIF is in the administrative down status

  The LIFs move to another port.

  When a node reboots or falls out of quorum

  The LIFs on that node fail over to the ports on other nodes. If a node returns to quorum, the LIFs automatically revert to the ports on the node, provided the ports are the home ports for the LIF and automatic revert is enabled on the LIF.

  For more information about quorum, see the Clustered Data ONTAP System Administration Guide for Cluster Administrators.

  When automatic revert is enabled on a LIF and that LIF's home port reverts to the administrative up status the LIF automatically migrates back to the home port."

• Question 196:

  A. NFSv1
  B. NFSv2
  C. NFSv3
  D. NFSv4
  C. NFSv3

• Question 197:

  You notice your indirect I/O performance between nodes in your 4-node cluster is slowing down from prior week. Each node has two 10 GB connections to the cluster interconnect, one to each switch. You are using four out of 12 available ports on each cluster interconnect switch. Your cluster network utilization is over 80%.

  What should you do to increase cluster interconnect performance?

  A. Change the SFP+ from 10 Gb to 16 Gb on each node and switch.
  B. Add two more cluster interconnect connections per node.
  C. Add additional ISLs between the two cluster interconnect switches.
  D. Change the cable from TwinAx to optical with SFP+ for better throughput.
  B. Add two more cluster interconnect connections per node.
