Which two requirements are needed to facilitate over-the-top DCI? (Choose two.)

The correct answer is A. All leaf VTEPs in each network must be reachable. D. EVPN route-types must be advertised to all leaf devices.

Explanation

All leaf VTEPs in each network must be reachable: In over-the-top Data Center Interconnect (DCI) using EVPN-VXLAN, the leaf VTEPs (VXLAN Tunnel Endpoints) in both data centers need to be reachable from each other. This is crucial for the successful exchange of VXLAN traffic and the proper operation of the overlay network between the data centers. EVPN route-types must be advertised to all leaf devices: To extend Layer 2 and Layer 3 services seamlessly across data centers in OTT DCI, EVPN route types must be advertised to all leaf devices to maintain the unified control plane and support endpoint reachability.
