B.MAC/IP routes, A-D per EVI routes, and A-D per ES routes

C.A-D per EVI routes, A-D per ES routes, and Ethernet segment (ES) routes

D.A-D per EVI routes and ES routes only

Which of the following statements about EVPN auto-discovery per Ethernet segment (A-D per ES) routes is TRUE?

A.The updates include an Ethernet segment identifier label that is used in loop prevention.

B.The updates advertise the Ethernet segment availability in a given EVPN service.

C.The updates include an MPLS label that is set to a non-zero value.

D.The updates include an Ethernet tag ID that is set to zero.

Which of the following statements about multi-homing for a Layer-2 service is TRUE?

A.In the single-active mode, the CE requires a LAG to be configured between the CE and all attached PEs.

B.In the single-active mode, the CE forwards traffic to all attached PES and receives traffic from a single PE.

C.In the all-active mode, all PES attached to a CE can forward traffic to and from the CE.

D.The Nokia 7750 SR supports a CE being multi-homed to a maximum of two PEs.

Which of the following statements about an EVPN with integrated routing and bridging (EVPN-IRB) service is FALSE?

A.This service requires the use of EVPN-MPLS for data plane.

B.In this service, the IRB interface acts as a default gateway for hosts in the corresponding subnet.

C.This service consists of a VPRN and multiple VPLSs.

D.This service enables the use of EVPN to provide connectivity between hosts in different subnets.

In the exhibit, the EVPN-IRB is using the interface-ful unnumbered model and is fully operational. Which of the following statements isFALSE?

A.An MP-BGP session that supports the advertisement of VPN-IPv4 routes is established between PE3 and PE4.

B.An MP-BGP session that supports the advertisement of EVPN routes is established between PEI and PE2.

C.On PE3, the routing table for VPRN 15 contains an entry for 10.10.1.0/24. This entry is resolved to MAC-OI as an overlay index.

D.On PE3, the routing table for VPRN 15 contains an entry for 10.10.4.0/24. This entry is resolved using a transport tunnel towards PEA.
