You have implemented a new Frame Relay network in your organization. However it is not functioning properly, since the inverse ARP is working erroneously. Which of the following commands should you use to provide connectivity?
  1. frame-relay arp
  2. frame-relay interface-dlci
  3. frame-relay lmi-type
  4. frame-relay map
Explanation
Answer - D - You can use the frame-relay map command to provide connectivity on a Frame Relay network.

Key Takeaway: The frame-relay map command need not be used on point-to-point subinterfaces. This is because the end point of the point-to-point connection automatically resides on the same subnet as the start point. It is also not required to enable or disable Inverse ARP, because there is only a single remote destination on a point-to-point PVC and discovery is not necessary. In a multipoint subinterface, the frame-relay map command can be used to associate the multipoint subinterface with specific DLCIs.
