Suggested answer: C

Explanation:

The feature of the Aruba 8400 switch that you should explain to the customer is Virtual Switching Extension (VSX). VSX is a cluster technology that allows two VSX switches to run with independent control planes (OSPF/BGP) and present themselves as different routers in the network67. In the data path, however, they function as a single router and support active-active forwarding6. This means that VSX provides high availability, resiliency, and load balancing for both Layer 2 and Layer 3 traffic8. VSX also enables hitless software upgrades without any service disruption or packet loss9, which addresses the customer's concern about having no maintenance window even for core switch software upgrade.
