CCDE: Cisco Certified Design Expert (Practical) — Question 75

A business wants to refresh its legacy Frame Relay WAN. It currently has product specialists in each of its 200 branches but plans to reduce and consolidate resources. The goal is to have product specialists available via video link when customers visit the nationwide branch offices. Which technology should be used to meet this objective?

Answer options

• A. DMVPN phase 1 network over the Internet
• B. Layer 3 MPLS VPN hub and spoke
• C. Layer 2 VPLS
• D. Layer 3 MPLS VPN full mesh

Correct answer: D

Explanation

The correct answer is D, as a Layer 3 MPLS VPN full mesh allows all branch offices to communicate directly with each other, providing the necessary bandwidth and low latency for video conferencing. Options A and B do not support the same level of direct connectivity and performance for video links. Option C, Layer 2 VPLS, while useful for some applications, does not provide the routing flexibility needed for video conferencing across multiple locations.
