Refer to Exhibit, If the user at extension 1001 dials the user at extension 2002, which dial peer is used to route the call?

The correct answer is A. 3. Again applying the longest prefix match rule: dial peer 3 has a destination-pattern that exactly matches 2002. While broader patterns (e.g., '200.' or '2...') could also match 2002, those are less specific. The IOS router picks the dial peer whose pattern has the greatest…

Explanation

Again applying the longest prefix match rule: dial peer 3 has a destination-pattern that exactly matches 2002. While broader patterns (e.g., '200.' or '2...') could also match 2002, those are less specific. The IOS router picks the dial peer whose pattern has the greatest number of explicitly matched digits. Dial peer 3's exact four-digit match for 2002 wins over any two-digit or three-digit explicit prefix combined with wildcards. This demonstrates the importance of dial peer ordering by specificity - the most precise pattern always takes priority in Cisco IOS dial peer selection.
