C. A load balancer provides external access to Supervisor Clusters and Tanzu Kubernetes clusters. In vSphere with Tanzu using the vSphere networking stack, a load balancer is typically used to provide external access to Supervisor Clusters and Tanzu Kubernetes clusters. It helps distribute incoming traffic among the nodes in the Kubernetes cluster and allows external clients to access services deployed in the Tanzu Kubernetes clusters. The load balancer ensures high availability and efficient distribution of traffic to the appropriate resources within the environment.

Not super sure about this one but will go with C. A. A load balancer balances pods between Tanzu Kubernetes cluster nodes. - No... balances pods? Doesn't sound right. B. A load balancer distributes Tanzu Kubernetes cluster nodes between ESXi hosts. - No, load balancers don't do workload placement, DRS does that. C. A load balancer provides external access to Supervisor Clusters and Tanzu Kubernetes clusters. - Maybe? D. A load balancer performs authentication and authorization for Supervisor Clusters and Tanzu Kubernetes clusters. - No, it's not a security/authentication thing. C seems the best answer.
