An administrator is deploying a vSphere Supervisor with NSX. What will determine the deployment size for the load balancer?

Answer

A. The Edge node form factor. Correct
B. The Edge cluster form factor.
C. The number of Kubernetes pods that will be deployed.
D. The number of vSphere Kubernetes clusters deployed.

Explanation

VCF 9.0 design guidance for the Supervisor NSX Load Balancer model states that the NSX load balancers run on NSX Edges, and sets explicit sizing requirements at the Edge node level. In the “NSX Load Balancer Design Requirements,” VCF 9.0 requires that the NSX Edge cluster must be deployed because “NSX Load Balancers run on NSX Edges.” It further requires that “NSX Edge nodes must be deployed with a minimum of Large form factor “because NSX load balancers have fixed resource allocations on NSX Edge nodes, and the Large form factor is needed to accommodate basic system and workload needs. This directly ties “deployment size” of the load balancer service capacity to the Edge node form factor(Small /Medium/Large, etc.) rather than the number of pods or the number of clusters. The document also notes that if additional load balancers are required, NSX Edges can be scaled up or out, again reinforcing that sizing is an Edge node sizing decision.
