Which of the following statements does NOT describe the functionality or operation of the integrated gateway-based data center interconnect solution?

A. The data center gateway and the WAN PE functions are performed on a single router.

B. The border leaf router will utilize eBGP or static routes to interconnect with the gateway.

Consider the exhibit.

Leaf-1 has received an ARP request from host-1 for host-2. Leaf-1 has added host-1's MAC address in its MAC table and host-1's MAC/IP addresses in its proxy-ARP table.
Which of the following steps is FALSE?

A. Leaf-1 sends a route-type 2 EVPN update with host-1's MAC with the IP address set to 192.168.100.1 to the remote peers.

B. The remote peers generate a gratuitous ARP towards their directly connected hosts to announce the learned IP/MAC mapping information.

C. The remote peers ignore the EVPN update with the IP address set to 0.0.0.0 and use the update with the IP address set to 192.168.100.1 to populate their MAC forwarding tables.

D. Leaf-1 sends a route-type 2 EVPN update with host-1's MAC with the IP address set to 0.0.0.0 to the remote peers.
