Q:

How should a router that is being used in a Frame Relay  network be configured to keep split horizon issues from preventing routing updates

A) Configure a seperate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface B) Combine multiple Frame Relay circuits as a point-to-point line to support multicast and broadcast traffic

Answer & Explanation Answer: A) Configure a seperate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface

Explanation:

If you have a serial port configured with multiple DLCIs connected to multiple remote sites, split horizon rules stop route updates received on an interface from being sent out the same interface. By creating subinterfaces for each PVC, you can avoid the split horizon issues when using Frame Relay.

Answer & Explanation Answer: A) Supplied by the CSU/DSU

Explanation:

Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your non-production test environment, then you need to supply clocking with the clock rate command on the serial interface of the router with the DCE cable attached.
