Designing Cisco Enterprise Networks (ENSLD) — Question 162

Which WAN connectivity technology is optimal for edge computing compared to others and why?

Answer options

• A. Due to high bandwidth, separation and security, and proximity to the data center network, DWDM is the optimal WAN technology for edge computing compared to 4G/5G connectivity, which offers native separation and security with close proximity to the data center.
• B. Due to low latency, high bandwidth, and closest proximity to the user, 4G/5G connectivity is the optimal WAN technology for edge computing compared to L3 VPN MPLS connectivity, which offers native separation and security with close proximity to the data center.
• C. Due to low cost, high bandwidth, low latency, and closest proximity to the edge of the network, Mero Ethernet is the optimal WAN technology for edge computing compared to MPLS, which offers native separation and security with close proximity to the data center.
• D. Due to low latency, high bandwidth, and closest proximity to the user, L3 VPN MPLS connectivity is the optimal WAN technology for edge computing compared to 4G/5G connectivity, which offers native separation and security with close proximity to the data center.

Correct answer: B

Explanation

The correct answer is B because 4G/5G connectivity offers low latency and high bandwidth, making it ideal for edge computing applications that require quick data processing close to the user. Other options, such as DWDM, Mero Ethernet, and L3 VPN MPLS, do not provide the same level of proximity to the user, which is critical for optimizing edge computing performance.
