C.

PE2 receives a single A-D per EVI route. The route is originated from PE3.

D.

PE2 receives two A-D per ES routes: one from PEI and another from PE3.

Based on the exhibit below, which of the following statements is FALSE?

A.

When forwarding BUM traffic, the local PE must replicate the traffic and send it as unicast to the advertising neighbor.

B.

The MPLS label 524284 presented indicates the service label value that the neighbor 10.10.10.2 uses to forward BUM traffic to PEI.

C.

When forwarding BUM traffic, the local PE uses an MPLS transport tunnel towards the advertising neighbor.

D.

The IMET route is imported by a local VPLS configured with a route-target value of 65100:10.

Which of the following statements about the operation of a single-homed EVPN VPWS is TRUE?

A.

The same tag ID must be configured for the local attachment circuit (AC) at each PE.

B.

Each PE advertises a MAC route and an A-D per EVI route when its local AC becomes operationally UP.

C.

The advertised A-D per EVI route includes a non-zero tag ID and a non-zero MPLS label.

D.

Each PE verifies that the received tag ID matches its configured local AC tag ID.

Which of the following statements about PE-to-PE MAC address advertisement is FALSE?

A.

The service distinguisher (label or VNI) is advertised with the MAC/IP EVPN update.

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.

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.

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 the EVPN Layer 2 Attributes extended community is FALSE?

A.

B.

It is applicable to EVPN VPLS services.

C.

It specifies the service maximum transmission unit (MTU).

D.

C.

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