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?

Question # 1

Options:

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.

Questions # 2:

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

Question # 2

Neighbors 10.10.10.2 and 10.10.10.3 have proxy-ARP enabled for the VPLS.

C.

Neighbors 10.10.10.2 and 10.10.10.3 have a service that uses a network identifier of 10.

D.

PEI uses VXLAN tunnels to reach neighbors 10.10.10.2 and 10.10.10.3.

Questions # 3:

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

Question # 3

Options:

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.

Questions # 4:

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

Options:

A.

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.

Questions # 5:

Examine the exhibit.

Options:

A.

The flooding list maintained by PEI for VPLS 20 contains three entries: PE2, PE3, and PE4.

B.

PE3 advertises an IMET route to PEI when its VPLS 20's mesh-SDP becomes operationally UP.

C.

PE3 signals a service label to PE4 when its VPLS 20 is enabled and is bound to an operational SDP.

D.

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.

Questions # 8:

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

Question # 8

Options:

C.

A PE uses a single MP-BGP session with a remote peer to exchange the routes for all EVIs.

D.

A PE advertises locally-learned MAC addresses to remote PES using EVPN type-2 routes.

Questions # 10:

Which of the following statements about EVPN auto-discovery per EVPN instance (A-D per EVI) routes is FALSE?

Options:
