Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 161

Which private VLAN can have only one VLAN and be a secondary VLAN that carries unidirectional traffic upstream from the hosts toward the promiscuous ports and the gateway?

Answer options

• A. isolated VLAN
• B. primary VLAN
• C. community VLAN
• D. promiscuous VLAN

Correct answer:

Explanation

The correct answer is A, isolated VLAN, as it is specifically designed to restrict communication between hosts while allowing them to send traffic to the promiscuous ports. The primary VLAN serves as the main VLAN, while community VLANs allow communication among specific hosts, and promiscuous VLANs can communicate with all ports, making them incorrect choices for this scenario.
