Which technology is best recommended for interconnecting several branch offices across a metropolitan area that need to handle voice, video, and data?

• A. MPLS VPN
• B. Ethernet WAN
• C. Frame Relay
• D. ISDN

Answer: (B)

The most suitable technology for interconnecting several branch offices across a metropolitan area that require voice, video, and data capabilities is Ethernet WAN. Ethernet WAN offers high bandwidth and low latency, making it an optimal choice for handling the requirements of modern business communications, including real-time services like voice and video. Ethernet technology is widely adopted due to its flexibility, simplicity, and cost-effectiveness. It can efficiently manage varying amounts of data traffic, which is essential when multiple branch offices need to communicate simultaneously. Additionally, Ethernet WAN can be easily scaled to accommodate growth in network demands, and its architecture supports quality of service (QoS) features that prioritize critical traffic types, such as voice and video. While MPLS VPN is also a strong candidate for providing secure and reliable connectivity and can support voice and video, Ethernet WAN is often more straightforward to implement within a metropolitan area due to the existing infrastructure. Frame Relay and ISDN, although formerly popular, have become less favored due to their limitations in bandwidth and ability to handle modern multimedia applications effectively.
