What are the steps used to configure a point-to-point Ethernet-emulated WAN link?

  1. Turn on the interfaces, define a description for the WAN link

  2. Assign IP addresses, enable SSH access

  3. Configure OSPF, set up NAT

  4. Verify the interfaces, set up DHCP server

The correct answer is: Turn on the interfaces, define a description for the WAN link

To configure a point-to-point Ethernet-emulated WAN link, the initial steps involve enabling the interfaces and defining a description for the WAN link. Activating the interfaces is crucial as it allows them to participate in routing and data transmission, while a description helps network administrators understand the purpose of the link in the context of the network, facilitating easier management and troubleshooting. Assigning IP addresses is an essential part of establishing communication across the link; however, it is not part of the very first steps in the configuration process, which is why defining a description and turning on the interfaces is prioritized first. The foundational setup of the link must take precedence before more complex configurations such as routing protocols or security measures are implemented.
