Which of the following Dial on Demand Routing (DDR) commands allows a five-minute delay before disconnecting a call?



  1. The dialer idle-timeout 5 command
  2. The dialer idle-timeout 300 command
  3. The dialer load-threshold 5 command
  4. The dialer load-threshold 300 command

Answer:
B. The dialer idle-timeout 300 command


Tutorial:
The dialer idle-timeout 300 command allows a five-minute delay before disconnecting a call. This command specifies the number of idle seconds before a call is disconnected. The syntax for the command is as follows:


dialer idle-timeout seconds


The default number of seconds for the dialer idle-timeout seconds command is 120 seconds. As long as interesting traffic is crossing the connection, the timeout value is reset to 120 or equal to idle-timeout value. Noninteresting traffic does not reset the timer. Once the timer reaches 0, the DDR connection is terminated.


The dialer idle-timeout 5 option is incorrect. The dialer idle-timeout command uses seconds, not minutes, to specify the idle time before a call is disconnected.


The dialer load-threshold 5 and dialer load threshold 300 options are incorrect. The dialer load-threshold command is used to set the maximum amount of interface load before the dialer places another call. It does not specify the number of idle minutes or seconds before a call is disconnected.…
