Why each option

To maximize VXLAN load balancing with five VMNICs on a host using AVS for Virtual Manager integration, you should configure four VMKNICs.

A2

Two VMKNICs would not maximize load balancing given five available VMNICs; it would underutilize the network resources.

B3

Three VMKNICs would not maximize load balancing as effectively as four, still leaving unused capacity for VXLAN traffic.

C4Correct

When using AVS for Virtual Manager integration with five VMNICs on a host, and aiming to maximize VXLAN load balancing, it is recommended to dedicate four VMNICs for VXLAN traffic. This setup provides sufficient bandwidth and redundancy for data traffic while typically reserving one VMNIC for management traffic (e.g., vMotion, host management).

D8

Eight VMKNICs is more than the five VMNICs available on the host, making it an impossible configuration in this scenario.
