Explanation
Cisco IOS dial peer selection follows a best-match algorithm: the router compares the dialed digits against all configured destination-pattern entries and selects the dial peer with the most specific (longest) matching pattern. Dial peer 2 contains the destination pattern that most precisely matches extension 2011. If multiple dial peers match equally, the router uses the lowest dial peer tag number as a tiebreaker. Without seeing the exhibit, the correct answer confirms that dial peer 2's destination pattern is a longer or more specific match for '2011' than any competing peer, making it the winning selection.
