You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network. In this scenario, which statement is correct?

• You must assign a unique site number to each attached site's configuration.
• This type of VPN only supports Ethernet interfaces when connecting to CE devices.
• This type of VPN requires the support of the inet-vpn NLRI on all core BGP devices
• You must use the same route-distinguiaher value on both PE devices.

You are a network architect for a service provider and want to offer Layer 2 services to your customers You want to use EVPN for Layer 2 services in your existing MPLS network.Which two statements are correct in this scenario? (Choose two.)

• Segment routing must be configured on all PE routers.
• VXLAN must be configured on all PE routers.

Exhibituser@Rl show configuration interpolated-profile { interpolate {fill-level [ 50 75 drop---probability [ > }class-of-service drop-profiles];20 60 ];Which two statements are correct about the class-of-service configuration shown in the exhibit? (Choose two.)

• The drop probability jumps immediately from 20% to 60% when the queue level reaches 75% full.
• The drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to 75% full
• To use this drop profile, you reference it in a scheduler.
• To use this drop profile, you apply it directly to an interface.

• When the encapsulation is vlan-ccc or extended-vlan-ccc, the configured VLAN tag is not included in the control plane LDP advertisement
• When the encapsulation is ethernet-ccc, only frames without a VLAN tag are accepted in the data plane
• When the encapsulation is vLan-ccc or extended-vlan-ccc, the configured VLAN tag is included in the control plane LDP advertisement
• When the encapsulation is ethemet-ccc, tagged and untagged frames are both accepted in the data plane.
