最新的 Nokia Certified Data Center Fabric Professional 4A0-D03 免費考試真題:

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

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

A) All routers participating in the Ethernet segment must have the multi-homing mode set to all-active.
B) The centralized router will advertise the customer prefixes using an EVPN route-type 5 update.
C) Remote leaf routers can load balance traffic to customer prefixes through the leaf routers connected to the Ethernet segment.
D) The centralized router must be a member of the Ethernet segment.

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

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

4. Which of the following statements about a distributed Layer 2 EVPN is FALSE?

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

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

A) The leaf routers are able to establish a full mesh of VXLAN tunnels across the WAN.
B) The EVPN overlay is transparently carried over the WAN network.
C) The data center gateway routers maintain a MP-BGP EVPN peering with the data center route reflector.
D) The IP addresses of the leaf routers need to be re-distributed into the WAN.
