Refer to the exhibit. To begin implementing EVPN Native with the software MAC learning feature, an engineer has applied this configuration to router PE1. Source MAC addresses learned on PE1 must be stored as dynamic MAC entries and updated on PE2 as static remote MAC addresses.
Which additional configuration must the engineer apply to PE1 to complete the EVPN Native implementation?

• A.  PE1 (config)# router bgp 6200
  PE1(config-bgp)# address-family 12vpn evpn
  PE1(config-bgp)# neighbor 30.30.30.30
  PE1(config-bgp-nbr)# remote-as 6200
  PE1(config-bgp-nbr)# update-source Loopback 0
  PE1(config-bgp-nbr)# address-family 12vpn evpn
• B.  PE1(config)# evpn
  PE1(config-evpn)# evi 5001
  PE1(config-evpn-evi)# advertise-mac
  PE1(config-evpn-evi)# unknown-unicast-suppress
  PE1(config-evpn-evi)# control-word-disable
  PE1(config-evpn-evi)# load-balance flow label static
  PE1(config-evpn-evi)# bgp
  PE1(config-evpn-evi)# route-target import 200:101
  PE1(config-evpn-evi)# route-target export 200:101
  PE1(config)# router bgp 6200
  PE1(config-bgp)# address-family 12vpn evpn
  PE1(config-bgp)# neighbor 30.30.30.30
  PE1(config-bgp-nbr)# remote-as 6200
  PE1(config-bgp-nbr)# update-source Loopback 0
  PE1(config-bgp-nbr)# address-family 12 vpn evpn
• C.  PE1(config)# 12vpn
  PE1(config-12vpn)# xconnect group evpn-vpws
  PE1(config-12vpn-xc)# p2p evpn1
  PE1(config-12vpn-xc-p2p)# interface Gig 1/0/1
  PE 1(config-12vpn-xc-p2p)# neighbor evpn evi 100 target 12 source 10
  PE1(config-12vpn-xc-p2p)# commit
• D.  PE1(config)# 12vpn
  PE1(config-12vpn)# xconnect group evpn-vpws
  PE1(config-12vpn-xc)# p2p evpn1
  PE1(config-12vpn-xc-p2p)# interface Gig 1/0/1
  PE1(config-12vpn-xc-p2p)# neighbor evpn evi 100 target 12 source 10
  PE1(config)# router bgp 6200
  PE1(config-bgp)# address-family 12vpn evpn
  PE1(config-bgp-af)# neighbor 192.168.10.1
  PE1(config-bgp-af)# commit

Refer to the exhibit. A service provider network uses BGP as its PE-to-CE routing protocol.
Customer A is dual-homed to the service provider via CE1. A network engineer is implementing EVPN native with active load balancing so that customer A's traffic can more efficiently use both links. Which action must the engineer take?

• A.  Configure PE1 and PE2 with the same ESI.
• B.  Configure CE1 to send labels through BGP.
• C.  Configure PE1 and PE2 for ARP suppression.
• D.  Configure separate physical interfaces on CE1 for the two PE connections.

What is the primary benefit provided by Unified MPLS?

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

What is the difference between inter-AS VPN and intra-AS VPN?

• A.  Inter-AS VPN uses route reflectors to distribute VPN routes between AS, and intra-AS VPN operates without route reflectors.
• B.  Inter-AS VPN mandates a separate VPN instance for each AS, and intra-AS VPN merges all VPN instances into a single global instance.
• C.  Inter-AS VPN requires cooperation between different autonomous systems to handle label distribution, and intra-AS VPN relies on an internal label-distribution mechanism.
• D.  Inter-AS VPN uses eBGP and MPLS to extend VPN services across ASBRs, and intra-AS VPN uses IBGP, MPLS, and route reflectors to manage VPN routing and label forwarding.

Which routing requirement must be considered when OSPFv3 is implemented as the PE-CE routing protocol?

• A.  The CE and PE routers must establish an OSPF peering and an OSPFv3 peering.
• B.  The routes received from OSPFv3 must be redistributes into BGP to allow connectivity between customer sites.
• C.  The routes received from BGP must be statically entered on the CEs with the next hop set as the PE.
• D.  MPLS must be configured on the link between the PE and CE.
