Refer to the exhibit. A call with a destination alias of 15551001234 reaches a Cisco TelePresence VCS. Which transform will the destination alias match?
The correct answer is B. Transform 2. Cisco VCS evaluates transform rules in ascending priority order using regex pattern matching, and the alias 15551001234 satisfies the pattern in Transform 2 before any lower-priority transforms are reached.

Why each option
Cisco VCS evaluates transform rules in ascending priority order using regex pattern matching, and the alias 15551001234 satisfies the pattern in Transform 2 before any lower-priority transforms are reached.
Transform 1 has the highest priority but its regex pattern does not match the digit structure of 15551001234, so it is skipped.
Cisco VCS processes transforms sequentially by priority number. Transform 2 contains a regex pattern that matches the structure of the 11-digit alias 15551001234 - anchored to its leading digit sequence or total length - causing the VCS to apply that transform and halt further evaluation of remaining rules.
Transform 3 is a lower-priority rule that is never evaluated because Transform 2 already produces a match.
Transform 4 is the lowest-priority rule and is bypassed entirely once Transform 2 matches the alias.
