Which type of PVLAN port allows a host in the same VLAN to communicate only with
promiscuous hosts?

A.
Community host in the PVLAN

B.
Isolated host in the PVLAN

C.
Promiscuous host in the PVLAN

D.
Span for host in the PVLAN

Explanation:
The types of private VLAN ports are as follows:
+ Promiscuous – The promiscuous port can communicate with all interfaces, including the
community and isolated host ports, that belong to those secondary VLANs associated to the
promiscuous port and associated with the primary VLAN
+ Isolated – This port has complete isolation from other ports within the same private VLAN
domain, except that it can communicate with associated promiscuous ports.
+ Community — A community port is a host port that belongs to a community secondary
VLAN. Community ports communicate with other ports in the same community VLAN and with
associated promiscuous ports.
These interfaces are isolated from all other interfaces in other communities and from all
isolated ports within the private VLAN domain.
