From the exhibit, both branches have an SD-WAN zone named overlay with set advpn-select enable, and each SD-WAN member in that zone is assigned a transport-group value. Branch-A members: Branch-B members: In FCSS SD-WAN 7.6 ADVPN design, transport-group is used to constrain which underlays are allowed to form ADVPN shortcuts with each other. A spoke can establish an ADVPN shortcut only between interfaces that belong to the same transport-group on both sides. This prevents building shortcuts across dissimilar transports. Evaluating the options: Therefore, the valid shortcut pairing listed is between T2 on Branch-A and TA on Branch-B, which corresponds to Option D. An operational review should distinguish the rule that matches the traffic from the interface that is ultimately selected. Valid forwarding also depends on destination route eligibility, current member state and the applicable SLA or quality-selection algorithm. A diagnostic showing configured members alone is not conclusive evidence that all those members will carry a particular flow.
