An administrator is setting up a High Availability cluster with vmkernel port groups. Which IP address configuration meets High Availability requirements?

  1. 192.168.12.10

  2. 192.168.13.10

  3. 192.168.14.10

  4. 192.168.15.10

The correct answer is: 192.168.14.10

In a High Availability (HA) cluster within VMware environments, it's essential to ensure that the vmkernel port groups are properly configured to facilitate communication among the ESXi hosts. The use of unique IP addresses for each vmkernel port is crucial because it allows for the appropriate routing of heartbeats and failover traffic necessary for HA operations. The chosen configuration, which is the 192.168.14.10 address, meets the requirements for a typical HA setup. It is likely that the specific network setup for the HA cluster designates a particular subnet (in this case, the 192.168.14.x subnet) for HA traffic. This configuration ensures that all hosts in the HA cluster can communicate with one another over the same subnet without any issues, allowing for the heartbeats that monitor host health and enable failover mechanisms. In contrast, the other IP addresses (192.168.12.10, 192.168.13.10, and 192.168.15.10) may belong to different subnets, which would hinder communication among the cluster nodes and prevent the HA mechanism from functioning correctly. Maintaining all HA traffic on the same subnet is vital to ensure reliable and timely communication needed for effective cluster management and failover processes
