4A0-D03 Exam Training Practice Tests (Nokia SR Linux EVPN and Data Center Interconnect)]

Question 1

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. The last octet of the default virtual MAC assigned to the sub-interface is derived from the last octet of the chassis MAC. D. Two MAC addresses associated to the sub-interface are shown in the forwarding table of the MAC-VRF that contains the IRB sub-interface.

Question 2

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

A. IP-VRFs and MAC-VRFs can have multiple IRB interfaces. B. An IRB interface is used to logically interconnect a MAC-VRF to an IP-VRF on a PE. C. The IRB sub-interface must have at least one IP address. D. The IRB sub-interfaces can be configured with access control lists.

Question 3

Consider the exhibit.

Which of the following statements about the configuration and operation of this setup is FALSE?

A. The host will be required to be configured with a LAG. B. The ports that connect to the host are associated to ES-1. C. The Ethernet segment ES-1 is configured as single active. D. All traffic to and from the host will flow through Leaf1.

Question 4

Consider the exhibit.

All IP-VRFs are configured properly and are operational.
Which of the following statements is FALSE?

A. One of the connected leaf routers will be elected DF. B. All connected leaf routers will use an AD per ES update to advertise single-active redundancy. C. The elected DF will use the AD per EVI update to identify itself as primary. D. Only the elected DF will advertise the customer IP prefix route to the BGP route reflector.

Question 5

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

Question 6

Consider the exhibit.

All connected leaf routers have the same Ethernet segment configuration. The IP-VRF is configured properly and is operational.
Which of the following statements is FALSE?

A. A LAG must be configured on the connected leaf routers and the host. B. The EVI for the IP-VRF using this segment is 1000. C. The redundancy mode for this Ethernet segment is all-active. D. This Ethernet segment is configured for Layer 3 multi-homing.
