Which of the following is NOT a load-balancing policy for vSwitches?

In the context of VMware vSphere, load-balancing policies for vSwitches are essential for distributing network traffic across multiple physical NICs (pNICs) to optimize bandwidth utilization and ensure high availability. The option that is identified as not being a load-balancing policy is vNIC port-based load balancing.

The reasoning behind this is that while there are established load-balancing policies such as source MAC-based load balancing, which uses the MAC addresses of the originating hosts to determine the outbound NIC, and IP hash-based load balancing, which uses the combination of source and destination IP addresses to identify the appropriate pNIC, vNIC port-based load balancing is not a recognized policy in VMware's vSwitch configuration.

Explicit failover order is another approach, but it does not distribute traffic across multiple NICs in a load-balanced manner. Instead, it prioritizes which NICs to use first, with the understanding that if one fails, traffic will be directed to the next available NIC. This is useful for failover scenarios rather than load balancing.

Therefore, among the options provided, vNIC port-based load balancing stands out as not conforming to the standard load-balancing policies associated with vSwitches, which focus on effectively optimizing traffic distribution and managing network
