Which Aruba CX feature ensures non-disruptive software updates with minimal downtime? Exam Dumps 13/115

Live Upgrade is a specific feature in ArubaOS-CX designed to update the switch software with minimal service disruption. On systems with redundant management modules or in a Virtual Switching Framework (VSF) stack, Live Upgrade updates the standby member first. Once the standby is updated and ready, a graceful failover is initiated, making the newly updated member active. This process ensures the data plane continues to forward traffic throughout the upgrade, significantly reducing downtime compared to a standard reboot.

A. Virtual Switching Framework (VSF) is a stacking technology that virtualizes multiple switches into a single logical device. While it provides the high-availability foundation for a Live Upgrade, it is not the upgrade feature itself.

C. Multi-Chassis Link Aggregation (MC-LAG) is a high-availability feature that provides link and chassis redundancy for connected devices, but it is not a software update mechanism for the switches.

D. Zero Touch Provisioning (ZTP) is a deployment feature used to automate the initial configuration and software loading of a new switch, not for upgrading an already operational switch.
