JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2024) — Question 44

You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must be automatically provided with the correct VLAN ID needed for sending voice traffic to the EX Series switches.
In this scenario, which two solutions are required to accomplish this task? (Choose two.)

Answer options

• A. Enable LLDP-MED on appropriate access interfaces.
• B. Create two VLANs and assign them as VLAN members to the appropriate access interfaces.
• C. Enable the voice VLAN feature with the appropriate access interfaces and VLAN ID for voice traffic.
• D. Use LLDP on appropriate interfaces.

Correct answer: A, C

Explanation

The correct answers are A and C because LLDP-MED is essential for discovering the IP phones and configuring the VLAN automatically, while enabling the voice VLAN feature ensures that the correct VLAN ID is assigned for voice traffic. Options B and D do not provide the necessary configuration for automatic VLAN assignment specific to voice traffic.
