Examine the exhibit.

Which of the following statements about the operation of VPLS 20 is TRUE?

• A.PEI advertises a MAC route for MAC-OI when its VPLS 2(Ys SAP becomes operationally UP.
• 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.The flooding list maintained by PEI for VPLS 20 contains three entries: PE2, PE3, and PE4.

A Layer-3 EVPN service is configured to use the interface-ful unnumbered forwarding model. Which of the following statements isFALSE?

• A.The SBD IRB interface configured in the VPRN service has no IP address assigned to it.
• B.Each participating PE advertises a MAC/IP route that carries the MAC address of SBD IRB interface.
• C.The VPRN service is configured to allow the advertisement of IP prefixes.
• D.IP-Prefix routes exchanged between PES include a non-zero MAC address as an overlay index.

Which of the following EVPN routes are exchanged to support the operation of a multi-homed EVPN VPWS?

• A.Auto-discovery per EVPN instance (A-D per EVI) routes and Auto-discovery per Ethernet segment (A-D per ES) routes only
• 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 does NOT describe the operation of the Layer-3 EVPN asymmetric forwarding model?

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

Examine the exhibit.

Which of the following actions is performed by PEI after it receives a BUM packet from CEI?

• A.PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE2.
• B.PEI sends the packet to PE2 but not to PE3 because PE3 is connected to the originating ES.
• C.PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE3.
• D.PEI does not flood the packet because PEI is acting as non-designated forwarder (non-DF) for VPLS 10.
