A.

A supplementary broadcast domain (SBD) is configured as a routed VPLS.

B.

A VPRN service is configured and has an interface bound to the local VPLS.

C.

The advertisement of IP-Prefix routes is enabled in the SBD VPLS.

D.

An IP address is configured in the VPRN interface that is bound to the SBD VPLS.

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.

Which of the following statements about EVPN Layer-3 services that utilize the interface-ful model is TRUE?

A.

EVPN MAC/IP routes are used to advertise the IP prefixes of subnets attached to a VPRN.

B.

VPRN instances are interconnected using a supplementary broadcast domain (SBD) VPLS.

C.

Intra-subnet traffic is carried over the tunnels provided by the SBD VPLS.

D.

The MAC/IP routing information is used to populate the VPRN routing table at the remote PEs.

In the exhibit, the EVPN-IRB is configured to use the interface-ful unnumbered model. Which of the following statements regarding the route advertisement is FALSE?

A.

PEI advertises an EVPN IP-Prefix route for prefix 10.10.1.0/24 to PE3. The BGP update includes MAC-OI as on overlay index.

B.

PEI advertises an EVPN MAC route for MAC-OI to PE3. The BGP update includes the route-target value configured for VPRN 15.

C.

PE3 advertises a VPN-IPv4 route for prefix 10.10.1.0/24 to PE4. The BGP update includes an MPLS service label.

D.

PE4 advertises an EVPN IP-Prefix route for prefix 10.10.1.0/24 to PE2. The BGP update includes MAC-04 as an overlay index.

Examine the exhibit.

Which of the following configuration conditions is required for the proper operation of EVPN VPWS 2?

B.

The remote AC tag ID configured on PE2 must match the remote AC tag ID configured on PE3.

C.

The local AC tag ID and the remote AC tag ID configured on PE2 must match.

D.

The local AC tag ID configured on PEI must match the local AC tag ID configured on PE3.

which of the following statements about the forwarding of BUM traffic is FALSE?

A.

PE3 replicates the traffic and sends it to all PES in its VPLS I flooding list.

B.

PE3 adds an ESI label to packets forwarded to PEI because PEI is connected to the same Ethernet segment.

C.

PEI forwards the traffic received from PE3 to CEI, and CEI discards it based upon the ESI label.

D.

PE2 decapsulates the packets received from PE3 and forwards the frames to CE2.

In the exhibit,

MACI moves from PEI to PE2. Which of the following actions related to this MAC address mobility is performed?

A.

CEI generates an update message to PEI withdrawing its MAC.

B.

PEI generates an update message to remote PES identifying the new location of CEI.

C.

PE2 advertises a MAC/IP route for MACI with a sequence number higher than that received from PEI.

D.

B.

Route targets are used to uniquely identify routes between EVIS in the case of MAC address overlaps.

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.
