Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 24

A network engineer designs a new dial plan and wants to block a certain range of numbers (8135100 through 8135105). What is the most specific route pattern that can be configured to block only the numbers in this range?

Answer options

Correct answer: A

Explanation

The correct answer is A because it accurately matches the numbers 8135100 through 8135105 by allowing the last digit to be 0, 1, 2, 3, 4, or 5. Option B only covers 8135101 to 8135105, missing 8135100, while C incorrectly uses a negation that would block more numbers than intended. Option D is too broad and would block a wider range of numbers beyond the specified range.
