Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 329

What is the result during a WAN Edge software upgrade process if the version of the WAN Edge software is higher than the one running on a controller device?

Answer options

• A. The upgrade button is greyed out.
• B. The upgrade fails with a warning message.
• C. The upgrade proceeds with a warning message.
• D. The upgrade proceeds with no warning message.

Correct answer: B

Explanation

The correct answer is B because when the WAN Edge software version is higher than the controller's, the system prevents the upgrade from completing and issues a warning. Options A, C, and D are incorrect as they do not accurately describe the behavior of the upgrade under these circumstances.
