Which of the following private VLAN port types can communicate with promiscuous private VLAN ports but not with isolated private VLAN ports? (Select 2 choices.)

  • community ports
  • isolated ports
  • SPAN ports
  • promiscuous ports
  • trunk ports
Explanation:
Community private virtual LAN (VLAN) ports can communicate with promiscuous ports and with other ports that belong to the same community, but not with isolated ports. Isolated private VLAN ports, on the other hand, can communicate only with promiscuous ports. Promiscuous private VLAN ports are capable of communicating with any other type of port.
Private VLANs can be configured on a switch to help isolate traffic within a VLAN. Private VLANs provide Layer 2 separation between ports that belong to the same VLAN. Because the separation exists at Layer 2, the hosts can exist on the same IP subnet. The VLAN to which the hosts belong is called the primary VLAN. To create a private VLAN, you must create secondary VLANs and associate them with the primary VLAN.
Switch Port Analyzer (SPAN) ports are not a private VLAN port type. SPAN is a means of monitoring traffic on a switch by copying packets from a source port to a monitored port or mirrored port. In addition, trunk ports are not a private VLAN port type. Trunk ports are used to connect switches to other switches.
