Explanation

In CUCM, a Calling Search Space (CSS) is an ordered list of partitions. When Bob dials 3330, CUCM searches through each partition in CSS1 in order and applies pattern-matching rules. The correct answer is Partition A, 3XXX because: CSS1 includes Partition A (making it reachable by Bob), and the pattern 3XXX uses the 'X' wildcard which matches any single digit 0–9, so 3XXX matches 3330. Partition B, 3XXX is not included in CSS1 (or is searched after Partition A), so it would not be the first match. Partition C, 3333 and Partition D, 3333 use an exact pattern that does NOT match 3330 - they only match the literal number 3333. Partition A's 3XXX is the longest and most specific pattern in CSS1 that successfully matches 3330.
