Which feature of Aruba CX switches enables faster configuration rollbacks and stateful recovery? Exam Dumps 8/115

The Checkpoint and Rollback feature in ArubaOS-CX is specifically designed for configuration management. It allows an administrator to save a snapshot of the current running configuration, known as a "checkpoint," before implementing changes. If the new configuration causes issues, the administrator can quickly revert the switch's running configuration to the previously saved checkpoint. This provides a fast and reliable method for configuration rollbacks and stateful recovery to a known-good operational state.

A. Virtual Switching Extension (VSX) is a high-availability and redundancy feature that virtualizes two separate switches into a single logical device, preventing downtime during failures or upgrades.

B. Network Analytics Engine (NAE) is a built-in framework for network monitoring and troubleshooting. It uses scripts to analyze events and can automate actions but is not a configuration versioning tool.

D. Multi-Chassis Link Aggregation (MC-LAG) is a general high-availability concept. Aruba's implementation is VSX, which provides link and chassis redundancy, not configuration rollback capabilities.
