Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 77

When you configure private VLANs on a switch, which port type connects the switch to the gateway router?

Answer options

• A. promiscuous
• B. community
• C. isolated
• D. trunked

Correct answer:

Explanation

The correct answer is 'A. promiscuous' because a promiscuous port is designed to communicate with all VLANs within a private VLAN setup, including the gateway router. The other options, 'B. community' and 'C. isolated', are meant for specific types of traffic within a private VLAN and do not serve as a connection point to a router. 'D. trunked' refers to a different configuration that allows multiple VLANs over a single connection but does not specifically define the connection to the gateway in the context of private VLANs.
