HPE Aruba Certified Professional (ACP) – SD-WAN — Question 21

You are reviewing the configuration of a VSX lag and have noticed the command lacp fallback. Why might this have been configured?

Answer options

• A. For backwards compatibility with LACP v1.
• B. To allow operation with active or passive LACP.
• C. To support provisioning a gateway without LACP.
• D. For operation using a single partner LACP interface.

Correct answer: C

Explanation

The correct answer is C because the lacp fallback command allows a gateway to be provisioned without needing LACP, which is essential in certain network designs. Options A and B are incorrect as they do not pertain to the purpose of fallback, and D is also wrong since it does not capture the need for LACP-less operation.
