Consider the exhibit.
Host-2 is sending data to Host-1. The network is designed to use asymmetric routing.
Which of the following statements about the operation of the data plane is TRUE?
- A . Leaf-1 forwards the data for mac-vrf-2 towards Leaf-2 with a VNI of 2.
- B . Leaf-2 forwards the data for mac-vrf-2 towards the IP-VRF using its IRB interface.
- C . Leaf-2 IP-VRF consults the ARP table to learn Host-1 MAC address.
- D . Leaf-2 does a MAC look-up using mac-vrf-1 and forwards the data towards Host-1.

- A . VLAN tags are used to identify traffic between the data center border leaf and the WAN PE.
- B . The EVPN services in the data center are interconnected to different VPN services in the WAN.
- C . The separation between the border leaf and the WAN PE provides a clear demarcation for security and QoS.

Which of the following statements about the Layer 2 EVPN configuration/operation in a Nokia SR Linux is FALSE?
- A . The layer 2 EVPN is implemented as a MAC-VRF.
- B . MAC-VRF is configured with a VXLAN-interface towards each remote VTEP.

- B . The EVPN overlay is transparently carried over the WAN network.
- C . The leaf routers are able to establish a full mesh of VXLAN tunnels across the WAN.
- D . The data center gateway routers maintain a MP-BGP EVPN peering with the data center route reflector.
Which of the following statements about an integrated routing and bridging (IRB) interface is FALSE?
- A . An IRB interface is used to logically interconnect a MAC-VRF to an IP-VRF on a PE.
- B . IP-VRFs and MAC-VRFs can have multiple IRB interfaces.
- C . The IRB sub-interface must have at least one IP address.
- D . The IRB sub-interfaces can be configured with access control lists.
