Refer to the exhibit. A network engineer is implementing MLDP on router PE1 as shown to support routing and forwarding of multicast packets for multiple VRFs. The network design requires each PE router to join the MP2MP tree and receive traffic on MP2MP trees. Which additional command sequence must the engineer apply to PE1 to complete the configuration?

• A.vpn id 70:50
  route-target export 200:100
  route-target import 200:100
  mdt preference mldp pim
• B.ip vrf VRF
  rd 200:100
  vpn id 70:50
  route-target export 200:100
  route-target import 200:100
  mdt preference mldp pim
• C.mdt data mpls mldp 255
  mdt data threshold 20 list 1
• D.mdt preference mldp
  mdt default mpls mldp 192.168.20.1
  mdt data mpls mldp 255
  mdt data threshold 20 list 1

Refer to the exhibit. A network engineer applies a configuration to multiple PE routers participating in an MLDP. Each PE creates the same VRF to support a single customer, which has officers located in several different regions. The PEs provide connectivity for hosts that use multicast services across a VPN. After the configuration is applied and the PEs are brought up, which additional action must the engineer take to enable multicast in the network?

• A.Implement PIM-DM on all P routers within the service provider core.
• B.Set a common VPN ID on each participating PE.
• C.Enable PE routers to send labels for multicast traffic only.
• D.Implement bidirectional PIM on all PE routers within the service provider core.

What is the primary benefit provided by Unified MPLS?

• A.It uses BGP to transport labels between different IGP domains which reduces the need to exceed the router's IGP route threshold.
• B.It allows IPV6 routes to be carried outside of BGP.
• C.It eliminates the need for labels to route traffic between autonomous systems.
• D.It expands the capability of link-state routing protocols to hold multiple routes.

Which configuration must be performed when an engineer implements MP-BGP to exchange IPV6 routes?

• A.BGP must be deployed in a fully meshed architecture within the autonomous system.
• B.BGP peering must be activated under the IPv6 address family.
• C.The participating routers must be configured within the same autonomous system
• D.The bgp default ipv4-unicast command must be implemented on each router participating in MP- BGP.

How do EFPs distinguish flows?

• A.by analyzing QoS tags
• B.by identifying one or more VLAN tag with wildcards
• C.by analyzing MPLS labels and QoS tags
• D.by associating each flow with a single IP address
