Correct Answer: B https://www.cisco.com/c/en/us/support/docs/voice/call-routing-dial-plans/14074-in-dial-peer-match.html The router or gateway matches the information elements in the setup message with the dial peer attributes to select an inbound dial peer. The router or gateway matches these items in this order: 1. Called number (DNIS) with the incoming called-number command 2. Calling Number (ANI) with the answer-address command 3. Calling Number (ANI) with the destination-pattern command 4. Voice-port (associated with the incoming call setup request) with configured dial peer port (applicable for inbound POTS call legs) 5. If no match is found in the first four steps, then the default dial peer 0 (pid:0) command is used.
