Nokia SR Linux EVPN and Data Center Interconnect Sample Questions:

1. Which of the following statements about the gateway-less data center interconnect solution is FALSE?

A) The data center border leaf and gateway can use either eBGP or static routes to exchange routing information.
B) It provides a clear demarcation for security between the border leaf and gateway.
C) All of the data centers leaf routers must be reachable over the WAN network.
D) The route reflectors must be reachable between different data centers.

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

A) The route reflectors in the different data centers must be able to reach each other.
B) The data center gateway and the WAN PE functions are performed on a single router.
C) The VXLAN tunnels are required between the leaf routers in the different data centers.
D) All the data center leaf routers must be reachable over the WAN network.

3. An IRB sub-interface that is being used to interconnect a MAC-VRF to an IP-VRF, is configured with anycast-gw set to true and anycast-gw enabled.
Which of the following statements is FALSE?

A) The same IP address used on this sub-interface can be used by other IRB sub-interfaces on remote PEs participating in the IP-VRF.
B) The host IP address of the sub-interface appears in the IP-VRF route table along with the prefix for the entire sub-net.
C) Two MAC addresses associated to the sub-interface are shown in the forwarding table of the MAC-VRF that contains the IRB sub-interface.
D) The last octet of the default virtual MAC assigned to the sub-interface is derived from the last octet of the chassis MAC.

4. Consider the exhibit.

The network is configured for interface-less symmetric routing with an ECMP of 4 enabled on all leaf routers.
Which of the following statements is FALSE?

A) IP-VRF1 on Leaf1, Leaf2 and Leaf3 must be configured with a VXLAN-routed interface.
B) The IRB interfaces on Leaf1 and Leaf2 must be configured to advertise learned local host-routes.
C) MAC-VRF100 on Leaf1 and Leaf2 must have BGP EVPN and BGP VPN configured.
D) Anycast gateway is an optional configuration on the Leaf1 and Leaf2 IRB interfaces.

5. 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 advertises the multi-homing mode used by the PEs for the Ethernet segment.
B) It is used by the remote peers for aliasing.
C) It contains the route-target so that the update can be imported into the correct MAC-VRF instance.
D) It contains the VNI that is to be used by the remote peers in the data plane.
