Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 45

An engineer is configuring a list that matches all IP prefixes with lengths from /1 to /16 in a centralized control policy. Which list accomplishes this task?

Answer options

• A. 0.0.0.0/0 le 16
• B. 0.0.0.0/1 le 16
• C. 0.0.0.0/0 ge 1
• D. 0.0.0.0/16 ge 1

Correct answer: A

Explanation

The correct answer, A, 0.0.0.0/0 le 16, includes all prefixes from /1 to /16 by allowing any prefix length up to a maximum of /16. Option B, 0.0.0.0/1 le 16, restricts the starting prefix to /1 but does not account for all possible prefixes. Options C and D do not correctly cover the range from /1 to /16 as they either start too high or do not limit the maximum length appropriately.
