   A financial services company is planning a new Supervisor Cluster that will host both production and development TKG workload clusters. The production clusters will handle sensitive customer transactions and require low latency and high availability. The development clusters will have sporadic traffic and can tolerate occasional downtime. The company has a limited budget and wants to minimize costs while meeting the production requirements. What is the most cost-effective load balancer design?

   • ADeploy a single medium load balancer without high availability for all clusters
   • BDeploy a medium load balancer with high availability for production clusters and a small load balancer without HA for development clusters
   • CDeploy a small load balancer for development clusters and rely on the Supervisor's built-in load balancing for production
   • DDeploy a single large load balancer with high availability for all clusters

   An administrator is planning the load balancer deployment for a Supervisor Cluster that will support 25 TKG workload clusters. The administrator is trying to determine the correct load balancer size. Which information is most important for this decision?

   • AThe number of administrators who will manage the load balancer
   • BThe physical size of the load balancer appliance in rack units
   • CThe version of the load balancer software
   • DThe total number of virtual servers required for the Supervisor and workload cluster endpoints

   An organization runs a production Supervisor Cluster that supports 50 TKG workload clusters. The load balancer is currently sized as 'medium'. After a recent expansion, users report that API requests to the Supervisor Cluster are timing out and workload cluster provisioning is slow. Monitoring shows the load balancer is consistently at 85% CPU utilization and the connection rate is at the medium size's limit. What should the administrator do to resolve the performance issue?

   • AConfigure the load balancer to use connection multiplexing to reduce the number of concurrent connections
   • BReduce the number of TKG workload clusters to decrease the load on the load balancer
   • CMove the workload cluster control plane endpoints to a separate load balancer to distribute the load
   • DIncrease the load balancer size to 'large' to provide more throughput and connection capacity

   Which practice helps ensure the load balancer size remains appropriate over time?

   • AAlways choose the largest available load balancer
   • BAvoid using load balancer logs to reduce storage usage
   • CRegularly review load balancer performance metrics
   • DSet the load balancer size once and never change it

   In a VMware vSphere with Tanzu Supervisor Cluster, what is the primary role of the load balancer?

   • ATo authenticate users and manage role-based access control
   • BTo provide DNS resolution for Supervisor Cluster services
   • CTo route and distribute traffic to the Kubernetes API server and other Supervisor services
   • DTo store persistent volumes for stateful workloads
