Which secondary Private VLAN type can communicate with and send packets to an Isolated PVLAN?

1. Community

2. Isolated

3. Promiscuous

4. Primary

The correct answer is: Promiscuous

The promiscuous type of Private VLAN (PVLAN) is designed to facilitate communication between different isolated and community VLANs, effectively serving as the communication channel for devices in those VLANs. This means that a promiscuous port can communicate with all other port types within the PVLAN configuration, including isolated ports. In the context of this question, isolated ports are unable to communicate with each other; they can only send traffic to the promiscuous port. By contrast, the promiscuous port can communicate with multiple VLANs, including isolated ones. This setup enhances security by allowing certain data flows while preventing others, which is essential in environments that require strict control over network communication. The other types of private VLANs, such as isolated and community, do not have the capability to connect directly with isolated ports in the same manner. Isolated ports can only communicate with promiscuous ports and not with each other, while community ports can communicate with other members of the community but not with isolated ports. Thus, the promiscuous type emerges as the only port type that can effectively interact with isolated ports, making it the correct answer.
