Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 130
An administrator needs to create a partial PRI consisting of the first seven timeslots available. Which configuration snippet configures the ISDN E1 PRI for this task?
Answer options
- A. config t 2900(config)#isdn switch-type primary-ni 2900(config)#pri-group timeslots 1-7
- B. config t 2900(config)#isdn switch-type primary-ni 2900(config)#controller e1 0/0/0 2900(config-controller)#pri-group timeslots 1-7
- C. config t 2900(config)#isdn switch-type primary-ni 2900(config)#interface Serial0/0/0:15 2900(config-controller)#pri-group timeslots 1-7
- D. config t 2900(config)#isdn switch-type primary-ni 2900(config)#controller e1 0/0/0 2900(config-controller)#pri-timeslots 1-7
Correct answer: B
Explanation
Option B is the correct answer because it properly configures the ISDN E1 PRI by specifying the controller and then indicating the desired timeslots for the PRI group. The other options either lack the necessary controller configuration or use incorrect commands such as 'pri-timeslots' instead of 'pri-group' for defining the timeslots.
