A. 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.

B. 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.

C. 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.

D. 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.
