JNCIP-SP: Juniper Networks Certified Professional – Service Provider — Question 1

You are provisioning a new VPLS on your PE router. Your customer needs to send Q-in-Q traffic across the VPLS.
In this scenario, which type of encapsulation is required on your PE router's VPLS interface?

Answer options

• A. ether-vpls-over-atm-llc
• B. extended-vlan-vpls
• C. vlan-vpls
• D. ethernet-vpls

Correct answer: C

Explanation

The correct encapsulation for transmitting Q-in-Q traffic over a VPLS is vlan-vpls, as it supports the necessary VLAN tagging. The other options, such as ether-vpls-over-atm-llc and ethernet-vpls, do not specifically cater to Q-in-Q traffic requirements, while extended-vlan-vpls is not the standard choice for this scenario.
