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.

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.

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

Each MAC-VRF used in the L3 EVPN network must exist on each PE.

Q30. Which of the following statements about the decoupled gateway-based data center interconnect solution is TRUE?

There is a clear demarcation for security and QoS between the data center border leaf and the WAN PE.

The WAN PE maintains a peering session with the data center route reflector.

Q31. Consider the exhibit.

Which of the following statements about the operation of all-active multi-homing is FALSE?

Both Leaf1 and Leaf2 can forward BUM traffic to the host.

Leaf3 can load balance traffic between Leaf1 and Leaf2 when ECMP is enabled on the MAC-VRF.

The Ethernet segment on Leaf1 and Leaf2 is associated to lag 1.

The host can forward BUM traffic to either Leaf1 or Leaf2.

Q32. Which of the following statements does NOT describe the functionality or operation of the integrated gateway-based data center interconnect solution?

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

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

The data center gateway needs to provide interworking between the VXLAN and the WAN tunneling protocol.

The data center gateway needs to be able to re-advertise Layer 3 EVPN routes of the leaf routers into VPN-IPv4 or VPN-IPv6 routes if required.

Q33. Which of the following statements about the configuration of a Layer 3 multi-homing with a centralized router is FALSE?

The centralized router must be a member of the Ethernet segment.

All routers participating in the Ethernet segment must have the multi-homing mode set to all-active.

Remote leaf routers can load balance traffic to customer prefixes through the leaf routers connected to the Ethernet segment.

The centralized router will advertise the customer prefixes using an EVPN route-type 5 update.

Q34. Which of the following statements describes the function or operation of the integrated gateway-based data center interconnect solution?

All the data center leaf routers must be reachable over the WAN network.

The route reflectors in the different data centers must be able to reach each other.

The VXLAN tunnels are required between the leaf routers in the different data centers.

VLAN tags are used to identify traffic between the data center border leaf and the WAN PE.

The EVPN services in the data center are interconnected to different VPN services in the WAN.

The separation between the border leaf and the WAN PE provides a clear demarcation for security and QoS.
