   A customer has a 6-node cluster using a 4-switch spine-leaf topology (2 spines, 2 leaves). They are experiencing high latency between nodes on different leaf switches. What is the most likely cause?

   • AThe inter-switch links are not configured with the correct VLAN.
   • BThe spine switches are not connected to both leaf switches.
   • CThe nodes are connected to the spine switches instead of the leaf switches.
   • DThe cluster has too many nodes for a 4-switch topology.

   You are cabling a 2-node cluster. You have connected node1's e0a to switch1 and e0b to switch2. Node2's e0a is connected to switch1 and e0b to switch2. The ISL is connected. You run 'cluster ping-cluster' and see that node1 can reach node2, but the latency is very high. What is the most likely cause?

   • AThe nodes are using different cluster port speeds.
   • BThe cluster is using a single switch for all traffic.
   • CThe management network is congested.
   • DThe ISL is operating at a lower speed than the node ports.

   What does the 'cluster ping-cluster' command check when verifying cluster cabling?

   • AIt checks the physical cable connections by sending a light pulse
   • BIt verifies that the cluster is in a healthy state
   • CIt checks the switch configuration for VLAN mismatches
   • DIt verifies that all cluster ports are up and that nodes can communicate with each other

   You have completed cabling a 2-node cluster. You run 'cluster ping-cluster -node node1' and it succeeds. You then run the same command from node2 and it also succeeds. What additional check should you perform to fully verify the cluster cabling is correct?

   • ACheck that the inter-switch link (ISL) is up and passing traffic.
   • BReboot both nodes to ensure the cluster forms cleanly.
   • CCheck the cluster switch power supplies for redundancy.
   • DVerify that the management ports are connected to the cluster switches.

   You have just cabled a 2-node cluster. You want to verify that the cluster interconnect is working correctly before joining the nodes. Which command should you run from the ONTAP CLI?

   • Acluster ping-cluster -node node1
   • Bnetwork ping -node node1 -destination node2
   • Csystem node show -node node1
   • Dstorage failover show -node node1
