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