Which secondary Private VLAN (PVLAN) type can communicate and send packets to an Isolated PVLAN?
The correct answer is C. Promiscuous. In a Private VLAN configuration, Promiscuous ports can send and receive traffic to and from all secondary PVLAN types, including Isolated ports, making them the only secondary type that can reach Isolated PVLANs.

Why each option
In a Private VLAN configuration, Promiscuous ports can send and receive traffic to and from all secondary PVLAN types, including Isolated ports, making them the only secondary type that can reach Isolated PVLANs.
Community PVLAN ports can communicate with other ports in the same Community and with Promiscuous ports, but are blocked from communicating with Isolated PVLAN ports.
Isolated PVLAN ports can only communicate with Promiscuous ports; two Isolated ports cannot exchange traffic with each other.
Promiscuous ports (typically used by routers or firewalls acting as the gateway) are permitted to communicate with all secondary PVLAN types - both Community and Isolated. An Isolated PVLAN port can only send traffic to and receive traffic from Promiscuous ports, so Promiscuous is the only type that can exchange packets with an Isolated PVLAN.
Primary is not a secondary PVLAN type - it is the main VLAN that acts as the parent for secondary Community and Isolated PVLANs.
