A vSphere 5 implementation consists of a fully automated DRS cluster with two ESXi 5.x hosts with the following vNetwork Standard Switch configuration:
1. Switch A: two vmnics, one port group named sFTP-PG
2. Switch B: one vmnic, one port group named Web-PG
3. All vmnics are trunked to the same physical switch.
DRS has been configured with an anti-affinity rule for all virtual machines in the Web-PG so that no more than half of the virtual machines run on any given host. The virtual machines on WebPG are experiencing significant network latency. The network team has determined that a performance bottleneck is occurring at the ESXi host level.
Which solution will require the least amount of administrative work and the least amount of service interruption?
Move a vmnic from Switch A to Switch B on each host
Migrate Web-PG to Switch A and sFTP-PG to Switch B on each host
Convert the three Switch Bs to a single vNetwork Distributed Switch
Use vMotion to redistribute some of the VMs in Web-PG to a different ESXi host
