Cisco Exam 350-801 Topic 13 Question 90 Discussion
Topic #: 13
The security department will audit an IT department to ensure that the proper guidelines are being followed. The reports of the call detail records show unauthorized access to PSTN. Which two actions should an administrator check to prevent the unauthorized use of the telephony system? (Choose two.)
When building a variable-length route pattern, you need to create a second route pattern followed by the # wildcard. This will allow the user to indicate the end of the number by dialing #. For example, if you want to create a route pattern for international calls, you would create a route pattern like this:
9.011!#
This route pattern will match any number that starts with 9.011, followed by any number of digits, and then ends with #.
The other options are incorrect because:
Configuring a single route pattern for international calls will not allow the user to indicate the end of the number.
Setting up all international route patterns to 0.! will not allow the user to indicate the end of the number.
Reducing the T302 timer to less than 4 seconds will not allow the user to indicate the end of the number.
