Answer: B

Explanation:

To allow Customer2 hosts to access the FTP server of Customer1, the routing needs to be configured in such a way that it allows traffic from Customer2’s VRF to reach the FTP server’s IP address in Customer1’s VRF. Option B provides the correct inter-VRF routing configuration. The first command creates a static route in Customer1’s VRF for the subnet 172.16.1.0/24 with the next hop set to 172.16.1.1 and specifies that the traffic should be routed to Customer2’s VRF. The second command creates a static route in Customer2’s VRF for the FTP server’s IP address 192.168.1.200/32 with the next hop set to 192.168.1.1 and specifies that the traffic should be routed to Customer1’s VRF. This configuration allows bidirectional communication between the two customers for the specified IP addresses.
