   An administrator is troubleshooting a performance issue on an ONTAP cluster. They notice that one node is handling significantly more client traffic than the other. What is the most likely cause of this imbalance?

   • AThe data LIFs are not distributed evenly across the nodes.
   • BThe node with more traffic has more storage shelves attached.
   • CThe cluster interconnect is saturated, causing traffic to be routed to one node.
   • DThe node with less traffic has a slower CPU.

   A company is deploying an ONTAP cluster with four nodes. They want to ensure that management access is available even if one node fails. What is the best approach?

   • AConfigure management LIFs on multiple nodes and use a DNS name that resolves to all of them.
   • BConfigure management LIFs only on the node with the lowest IP address.
   • CConfigure a single management LIF on one node and rely on that node's availability.
   • DUse the cluster interconnect network for management access.

   Which function is performed by a cluster controller in an ONTAP cluster?

   • AManaging only the network switches in the cluster
   • BServing data to clients over network protocols such as NFS and SMB

   What is the purpose of controller failover in an ONTAP cluster?

   • ATo improve network performance by load balancing traffic
   • BTo provide high availability by allowing another controller to take over storage serving if a controller fails
   • CTo increase storage capacity by adding more disks
   • DTo reduce power consumption by shutting down idle controllers
