Explanation

The NCC alert in this context is related to inter-cluster connectivity, likely for replication or Metro Availability. Confirming that the remote cluster is reachable and that ports 2009 and 2020 are open (A) is a foundational troubleshooting step - these ports are required for Nutanix cluster communication and replication traffic, and firewalls commonly block them. Checking if ping packets with an MTU of 9000 reach the destination cluster (D) verifies that jumbo frames are supported end-to-end across the network path, which is required for Nutanix replication performance; an MTU mismatch causes silent packet drops. Configuring NAT between clusters (B) is not recommended and not a solution - Nutanix replication requires direct IP reachability. Re-registering the remote site due to a changed cluster incarnation ID (C) is a valid fix in that specific scenario, but it is not a general first troubleshooting step and is more situational than A or D.
