Refer to the exhibit. Dedicated MPLS Layer 3 services for VRF customer A are configured on the MPLS network for FTP access. OSPF with area 0 configuration is used as the interior routing protocol between the routers, and LDP is up and running on the MPLS network. After recent maintenance work on the MPLS network, IP address 172.16.100.1 cannot access the FTP server with IP address 172.16.192.21. All loopbacks are reachable on the network. Which configuration must the engineer apply to correct the problem?

QUESTION NO: 9
Refer to the exhibit. A regional service provider provides connectivity for a growing enterprise, which recently acquired a new location in a nearby city. The new location, which is connected at CE2. requires connectivity to the company's data center, which is connected to CE1. The service provider will use VPNv4 to connect the two locations. The networking team is planning to implement segment-routing traffic engineering to route traffic from PE1 to PE2 over a delay- optimized path through P2. Which action must the engineering team take to begin the implementation?
