Implementing Cisco IP Telephony and Video Part 1 (CIPTV1, legacy) — Question 19

Which discard digits instruction removes all digits prior to the North American Numbering Plan portion of the route pattern?

Answer options

• A. PreDot
• B. PreAt
• C. Pre
• D. PreNANP B

Correct answer:

Explanation

The correct answer is D. PreNANP B, as it specifically targets and removes all digits leading up to the North American Numbering Plan part of the route pattern. The other options, such as PreDot, PreAt, and Pre, do not specifically address the North American Numbering Plan, making them unsuitable for this task.
