Which of the following statements does NOT describe the functionality or operation of the integrated...

Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:

In an integrated gateway-based DCI solution, the data center gateway and WAN PE functions reside on the same router. This device acts as the interworking point between the data center EVPN/VXLAN environment and the WAN transport service. It may need to translate or interwork between VXLAN encapsulation in the data center and MPLS or another WAN tunneling protocol in the WAN. For Layer 3 services, the integrated gateway may also re-advertise EVPN routes learned from the data center fabric into VPN-IPv4 or VPN-IPv6 routes for transport across the WAN. Option B does not describe the integrated gateway model. A border leaf using eBGP or static routes to interconnect with a gateway is a decoupled gateway-based design, where the data center border leaf and WAN PE/gateway are separate devices with a routing handoff between them. In the integrated model, that border-leaf-to-separate-gateway handoff is not the defining architecture because the gateway and WAN PE roles are combined on one router. Reference: integrated gateway DCI, VXLAN-to-WAN interworking, EVPN to VPN-IPv4/VPN-IPv6 re-advertisement, decoupled gateway distinction.
