Which description is correct for a private VLAN community port with respect to Layer 2 communications?
A. It communicates with all other community ports in the private VLAN domain.
B. It communicates with only isolated ports in the private VLAN domain.
C. It communicates only with other community ports in the same community and associated promiscuous ports.
D. It communicates only with associated promiscuous and isolated ports.
Correct Answer: C
Explanation/Reference:
Explanation:
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 at Layer 2 from all other interfaces in other communities and from all isolated ports within the private VLAN domain.
Because trunks can support the VLANs that carry traffic between promiscuous, isolated, and community ports, the isolated and community port traffic might enter or leave the device through a trunk interface.
