Which route pattern is matched based on the dialed number 29465?
The correct answer is B. 2946X. In Cisco CUCM, when multiple route patterns match a dialed number, the most specific pattern wins - the one with the greatest number of literal (non-wildcard) digit positions matched from left to right.

Why each option
In Cisco CUCM, when multiple route patterns match a dialed number, the most specific pattern wins - the one with the greatest number of literal (non-wildcard) digit positions matched from left to right.
2XXXX matches 29465 but has only one literal digit (2) before four wildcards, making it far less specific than 2946X.
2946X matches any number from 29460 to 29469, including 29465. It contains four consecutive literal digits (2, 9, 4, 6) before the wildcard X, making it the most specific match among all valid candidates. CUCM's best-match algorithm selects this pattern over less-specific alternatives that have fewer literal digit matches.
29XXX matches 29465 but has only two literal digits (2, 9) before three wildcards, so it loses to the more-specific 2946X.
294X is a 4-digit pattern and cannot match the 5-digit number 29465 at all.
29[0-5]XX matches 29465 since the digit 4 falls within [0-5], but it has only two unambiguous literal digits before the range expression, making it less specific than 2946X.
