Answer: B

Explanation:

To ensure that VMAC mode is enabled, you should run the command fw ctl get int fwha_vmac_global_param_enabled on all cluster members and check that the result of the command returns the value 11. This command shows the current value of the global kernel parameter fwha_vmac_global_param_enabled, which controls whether VMAC mode is enabled or disabled. VMAC mode is a feature that associates a Virtual MAC address with each Virtual IP address of the cluster, which reduces the need for Gratuitous ARP packets and improves failover performance1. The other options are incorrect. Option A is not a valid command. Option C is a command to show the status of cluster interfaces, not VMAC mode2. Option D is a command to show the value of a different global kernel parameter, fwha_vmac_global_param_enabled, which controls whether VMAC mode is enabled for all interfaces or only for non-VLAN interfaces1.
