Two sites have one WAN Edge each.
Each WAN Edge has two public TLOCs with no restrict configured.
There is full reachability between the TLOCs.
How many data tunnels are formed on each WAN Edge router?

A. B. C. D.A.
In a Cisco SD-WAN deployment, TLOC (Transport Locator) is used to identify a location and is associated with a device's WAN-facing interface. TLOC defines how traffic is forwarded across the overlay network, and it is a fundamental building block in the SD-WAN data plane.
In this scenario, two sites have one WAN Edge each, and each WAN Edge has two public TLOCs. There is no restriction configured on the TLOCs, and there is full reachability between them. Therefore, each WAN Edge router can form data tunnels with both TLOCs at the remote site.
So, each WAN Edge router will form two data tunnels for each TLOC at the remote site. Therefore, the total number of data tunnels formed on each WAN Edge router will be:
2 (TLOCs) x 2 (data tunnels for each TLOC) = 4
Hence, the correct answer is option C. 4.
