Nokia Certified Network Associate – SR OS Network Administration — Question 8

How does an H-VPLS reduce the full mesh requirement of a VPLS?

Answer options

• A. It uses only spoke SDPs to connect the core network and to connect to the MDU.
• B. It uses spoke SDPs to connect the core network, and mesh SDPs to connect to the MDU.
• C. It uses mesh SDPs to connect the core network, and spoke SDPs to connect to the MDU.
• D. It uses spoke SDPs to connect within a metro VPLS, and mesh SDPs to connect the two or more metro VPLS together.

Correct answer: D

Explanation

The correct answer is D because an H-VPLS architecture utilizes spoke SDPs for connections within a metro VPLS, which reduces the need for a full mesh, while mesh SDPs are used to interconnect different metro VPLS. Options A, B, and C do not accurately represent how H-VPLS operates in terms of reducing the full mesh requirement, as they misplace the roles of spoke and mesh SDPs.
