Why each option
The Cisco UCM route pattern 1[23]XX matches any four-digit number that starts with '1', followed by either '2' or '3', and ends with any two digits from '00' to '99'.
In Cisco UCM route patterns, [23] means the digit can be either 2 or 3, and XX represents any two digits from 00 to 99. Therefore, 1[23]XX matches numbers starting with '1', followed by '2' (e.g., 1200-1299) or '3' (e.g., 1300-1399), covering the range 1200 through 1399.
This range is too restrictive, as 1[23]XX allows for two variable digits, not just one.
This range is incorrect because XX represents two digits, not three, making the total number of digits four.
This range incorrectly includes 1300 as the upper bound, whereas 13XX would include numbers up to 1399.
