HPE Aruba Certified Professional (ACP) – SD-WAN — Question 64

You want to upgrade a re-provisioned Mobility Gateway that is currently using LACP. What feature will allow you to do this without removing interfaces from LAG?

Answer options

• A. LACP fallback
• B. LACP active
• C. LACP passive
• D. LACP static

Correct answer: A

Explanation

LACP fallback allows for an upgrade of the Mobility Gateway while keeping the existing interfaces in the Link Aggregation Group (LAG), thus avoiding any disruption. The other options (LACP active, LACP passive, and LACP static) do not provide the same capability to facilitate the upgrade without interface removal.
