If the route patterns 5XXX, 51XX, 513X, and 5134 exist within a call route database, which pattern would be matched if the dialed number was 5124?

The correct answer is B. 51XX. CUCM uses a longest (most specific) match algorithm. For dialed number 5124: 5XXX matches (any digit in positions 2-4), 51XX matches (second digit is 1, positions 3-4 are any), 513X does NOT match (third digit is 2, not 3), and 5134 does NOT match.

Explanation

CUCM uses a longest (most specific) match algorithm. For dialed number 5124: 5XXX matches (any digit in positions 2-4), 51XX matches (second digit is 1, positions 3-4 are any), 513X does NOT match (third digit is 2, not 3), and 5134 does NOT match. Between 5XXX and 51XX, the pattern 51XX is more specific because it constrains the second digit to '1'. CUCM selects the most specific matching pattern, so 51XX wins.
