Question#1

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.

Question#2

Which of the following statements about a distributed layer 2 EVPN is FALSE?

A. When a host connected to a layer 2 EVPN responds to an ARP request, it sends an ARP reply to the local leaf.
B. The local leaf replicates the ARP reply and sends it to all the leafs in the flooding list for that layer 2 EVP
C. The local leaf learns the source MAC address from the Ethernet frame and populates it into its MAC forwarding table.
D. The local leaf generates an EVPN route type 2 and sends it to all of its configured BGP EVPN neighbors.

Question#3

Which of the following four symmetric routing options does NOT require the use of an EVPN route-type 2?

A. Host routing
B. Prefix routing interface-less
C. Prefix routing interface-ful numbered
D. Prefix routing interface-ful unnumbered

Which of the following statements about a L3 EVPN network using symmetric routing is FALSE?

A. Each participating PE must support the use of EVPN route-type 5.
B. Ingress and egress PEs perform MAC and IP forwarding.
C. A routed-VXLAN interface is required on a per IP-VRF basis.
D. Each MAC-VRF used in the L3 EVPN network must exist on each P

Question#5

Which of the following statements about the decoupled gateway-based data center interconnect solution is FALSE?

A. VLAN tags are used to identify traffic between the data center border leaf and the WAN P
B. The EVPN services in the data center are interconnected to different VPN services in the WA
C. The separation between the border leaf and the WAN PE provides a clear demarcation for security and Qo
D. The WAN PE maintains a peering session with the data center route-reflector for the exchange of updates.
