[ INTERVIEW QUESTION ] vSphere Standard Switch (vSS) EXPLAINED.

Impressive Answers! If they ask you... How vSphere Standard Switch (vSS) works? EXPLAIN like a pro! vSS provides network connectivity to hosts and virtual machines. The physical NICs on the physical ESXi hosts are connected to the uplink ports on the vSphere Standard Switch. Then, virtual machines running in vSphere use virtual network adapters or vNICs to connect to port groups on the VSS. 

The vSphere Standard Switch can make use of more than one physical NIC from the ESXi host to handle network traffic to and from the port groups configured. The Interviewers will be impressed if you also mention... By either connecting physical NICs to the port groups on a vSphere Standard Switch, you can either have an isolated virtual switch (one where only VMs on the port group can communicate) or a virtual switch that is connected to the physical network.
