Question #13

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 IP-VRF consults the ARP table to learn Host-1 MAC address.

C. Leaf-2 forwards the data for mac-vrf-2 towards the IP-VRF using its IRB interface.

D. Leaf-2 does a MAC look-up using mac-vrf-1 and forwards the data towards Host-1.

Question #14

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. 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.

B. 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.

C. 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.

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

Question #15

Consider the exhibit.

All three of the leafs have a MP-BGP EVPN session to the route-reflector Spine-1. Leaf-1, Leaf-2 and Leaf-3 have existing instances of an L2 EVPN named MAC VRF-1. Host-1 has just sent its first Ethernet frame into MAC VRF-1 on Leaf-1.
Which of the following steps is FALSE?

A. Leaf-1 generates an EVPN route-type 5 update with Host-1's MAC address and sends it to the route reflector.

B. Leaf-2 and Leaf-3 import the EVPN update based upon the route target.

C. Leaf-1 populates Host-1's MAC address learnt on the local interface to its MAC table.

D. The route-reflector forwards the EVPN update to Leaf-2 and Leaf-3.

Question #16

Which of the following statements about configuring and using an integrated routing and bridging (IRB) interface is TRUE?

A. The IRB sub-interface must be configured as either type bridge or routed.

B. When the IRB sub-interface is configured with multiple IP addresses, one of them can be configured as the primary.

C. When using an IRB interface to interconnect a MAC-VRF to an IP-VRF, one sub-interface is configured for the MAC-VRF and another one for the IP-VRF.

D. A MAC-VRF can be configured with multiple IRB sub-interfaces to support multi-homing.

Question #17

Which of the following statements about a BGP route target is FALSE?

A. It is advertised with every EVPN route update.

B. It identifies the EVPN instance in the control plane.

C. It is defined in MP-BGP to allow for overlapping MAC addresses from multiple tenants.

D. The route-target is a BGP extended community.

Question #18

When PEs are connected to an Ethernet segment with at least one active MAC-VRF, which of the following statements about the AD per EVI updates sent by a PE is FALSE?

A. It contains the route-target so that the update can be imported into the correct MAC-VRF instance.

B. It contains the VNI that is to be used by the remote peers in the data plane.

C. It is used by the remote peers for aliasing.

D. It advertises the multi-homing mode used by the PEs for the Ethernet segment.
