• A. Proxy-ARP/ND is operational for a VPLS. Which of the following statements is FALSE?

Based upon the exhibit, which of the following statements is FALSE?

• A. VPLS 10 must be configured with two BGP instances on PE3 and PE4.
• B. On PE3 and PE4, VPLS 10 must be configured with two different route-distinguisher values: one for VXLAN and another for MPLS.
• C. On PE3 and PE4, VPLS 10 must be configured with two different route-target values: one for VXLAN and another for MPLS.
• D. A BGP export policy is required on PE3 and PE4 to ensure that IMET routes originated with VXLAN encapsulation are not advertised to the peer across the core network.

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.

Which of the following statements does NOT describe the operation of the Layer-3 EVPN asymmetric
forwarding model?

• A. All VPLS instances must be configured on all PES regardless of whether they have a local host or not.
• B. EVPN IP-Prefix routes are used to populate the VPRN VRF tables.
• C. The egress PE does not perform any Layer-3 route look up to forward traffic.
• D. The ingress PE performs both Layer-2 and Layer-3 look ups when forwarding traffic between subnets.

In the exhibit, the interface-less forwarding model is used for the Layer-3 EVPN service. Which of the
following statements about traffic forwarding from Host 1 to Host 2 is FALSE?

• A. PEI consults the FDB of RVPLS 1 and forwards the traffic to the local interface of VPRN 11.
• B. PEI encapsulates the packet with two labels: an outer transport label and an inner service label.
• C. PE2 inspects the service label and determines that it is associated with RVPLS 2.
• D. PE2 consults the FDB of RVPLS 2 and forwards the traffic to Host 2.

The interface-ful numbered model is used for a Layer-3 EVPN service. Which of the following
statements is FALSE?

• A. EVPN routes are advertised with a service label associated with the SBD VPLS.
• B. IP-Prefix routes exchanged between PES include a non-zero gateway IP address as an overlay index.
• C. EVPN MAC/IP routes are used to advertise the MAC and IP addresses of local hosts.
• D. EVPN MAC/IP routes are used to advertise the MAC and IP addresses of SBD IRB interfaces.

In the exhibit, the interface-ful numbered model is used for the Layer-3 EVPN service. Which of the
