Which WAN connectivity technology is optimal for edge computing compared to others and why?
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.
Due to high bandwidth, separation and security, and proximity to the data center network. DWDM Is the optimal WAN technology lor edge computing compared to 4G/5G connectivity, which offers native separation and security with close proximity to the data center.
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.
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.
What is the purpose of a TLOC extension in a Cisco SD-WAN network fabric?
to facilitate WAN Edge router redundancy within a site
to identify the physical interface where a WAN Edge router connects to the WAN transport network
to expand the number of colors that are potentially applied to a network transport interface
to aggregate multiple physical interfaces into a single logical Interface
