Exam 350-801 topic 1 question 180 discussion

The correct answer is C. 1200 through 1399 only. The route pattern "1[23]XX" will match any four-digit number that begins with "1" and has a second digit of either "2" or "3", with any value for the third and fourth digits. Therefore, the following dialed numbers will match this route pattern: 1200 1201 1234 1399 Option A is incorrect because it only includes the numbers between 1200 and 1300, whereas the route pattern matches any number between 1200 and 1399. Option B is incorrect because it includes numbers with five digits, whereas the route pattern only matches numbers with four digits. Option D is incorrect because it only includes numbers between 1230 and 1239, whereas the route pattern matches any number between 1200 and 1399.

C is true

Correct is C

I imagine on the test they give you this question in this exact order so you may accidentally pick A
