4A0-D03 Practice Questions

A.  

The original PE advertises the locally learned MAC with the sequence number set to a maximum value.

B.  

A PE advertising a local MAC that was previously learned through EVPN, will decrement the sequence number in its update.

C.  

The originating PE generates a withdraw message after the same locally learned MAC has aged out.

D.  

The originating PE and the destination PE must synchronize their MAC tables.

A.  

It allows the creation of a Layer 2 overlay network that can span the entire data center.

B.  

VXLAN was developed to support EVPN networks in the data center.

C.  

It may use ECMP to provide efficient utilization of the underlay interfaces within the data center.

D.  

It has the capability to isolate up to 16 million different overlays.

A.  

When a host connected to a Layer 2 EVPN responds to an ARP request, it sends an ARP reply to the local leaf.

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 learns the source MAC address from the Ethernet frame and populates it into its MAC forwarding table.

D.  

The local leaf generates an EVPN route type 2 and sends it to all of its configured BGP EVPN neighbors.

A.  

RT-1 Ethernet Auto-Discovery

B.  

RT-2 MAC/IP Advertisement

C.  

RT-3 Inclusive Multicast Ethernet Tag

D.  

RT-4 Ethernet Segment

A.  

The Ethernet segment ES-1 is configured as single active.

B.  

The ports that connect to the host are associated to ES-1.

C.  

All traffic to and from the host will flow through Leaf1.

D.  

The host will be required to be configured with a LA

G.  

A.  

An instance of each mac-vrf is required on each leaf.

B.  

The ingress PE will perform layer 2 and layer 3 lookups while the egress PE will perform layer 2 lookup.

C.  

The IRB configuration does not require anycast gateway configuration on the ip-vrf.

D.  

Forwarding information will be exchanged between the PEs using EVPN route-type 2 updates.
