Assuming that VLANs are not configured, what is true about traffic from a virtual machine connected to a port group on a vNetwork Standard Switch with no uplinks?
The virtual switch will drop the packets if no uplink is present.
Virtual machines on any vNetwork Standard Switch on the same ESXi host can receive the traffic.
Virtual machines in any port group on the virtual switch can receive the traffic.
Only virtual machines in the same port group on the virtual switch can receive the traffic.
