A switch has been configured with PVLANs. With what type of PVLAN port should the
default gateway be configured?

A.
isolated

B.
promiscuous

C.
community

D.
primary

E.
trunk

Explanation:
Promiscuous: The switch port connects to a router, firewall, or other common gateway
device. This port can communicate with anything else connected to the primary or any
secondary VLAN. In other words, the port is in promiscuous mode, in which the rules of
private VLANs are ignored.
