   Refer to the exhibit. Given this "debug isdn q921" output, what is the problem with the PRI?

   • ALayer 1 is down on the controller.
   • BPRI does not have an IP address configured on the interface.
   • CNothing, the PRI is sending keepalives.
   • DLayer 2 is down on the controller.

   Show answer

   Answer: D

   Explanation

   If Layer 2 is stable, the router and switch must begin to synchronize with each other. The Set Asynchronous Balanced Mode Extended (SABME) message appears on the display. This message indicates that Layer 2 tries to initialize with the other side. Either side can send the message and try to initialize with the other side. If the router receives the SABME message, it must send back an Unnumbered Acknowledge frame (UAf). https://www.cisco.com/c/en/us/support/docs/wan/t1-e1-t3-e3/8131-T1-pri.html
