To ensure redundancy on the management network after configuring High Availability (HA) on a cluster, adding an additional vmknic to the Network Adapters and moving it to Active adapters is crucial. This step allows for an extra virtual NIC to be utilized for management traffic, effectively providing a failover path in case the primary vmknic fails. By having multiple active adapters, the cluster maintains network connectivity and reliability, which is essential for HA to function properly.

This approach enhances the resiliency of the management network by ensuring that if one NIC becomes unavailable, the other can take over seamlessly, minimizing disruptions. The added redundancy through vmknics on the management network plays a significant role in maintaining high availability for both the VMs and the resources managed by VMware, ensuring operational continuity.

While other choices may touch upon configuration elements related to HA, they do not directly enhance redundancy in the same way that actively adding and configuring additional vmknics does.
