Exam HPE6-A72 topic 1 question 71 discussion

Regarding to the command reference guide, the answer B should be correct. https://www.arubanetworks.com/techdocs/AOS-CX/10.11/HTML/fundamentals_6300-6400/Content/Chp_Cfg_FW_mgt/Chk_cmds/che-rol.htm

After further research Strobelight is correct - answer is B: checkpoint rollback <name> start.

B is correct. The command documentation states "Applies the configuration from a pre-existing checkpoint or the startup configuration to the running configuration". The 'running configuration' is what's currently running. If it applied the checkpoint to the startup-configuration, then you'd have to reboot. Also, I'm not aware this command reboots the switch as part of the rollback, but even if that was the case then the answer still wouldn't be D because it doesn't restore the checkpoint to the startup-configuration and it wouldn't occur at the "next reboot", it occurs at command execution.

After further review it's D: This command will start the process of rolling back to the previous checkpoint. Checkpoint rollback is a feature that allows you to revert the switch's configuration to a previous checkpoint in case of a configuration error or issue. When you execute the checkpoint rollback start command, the switch will prompt you to confirm the rollback operation. If you confirm the operation, the switch will reload and restore the configuration from the previous checkpoint. Once the switch has completed the rollback operation and has restarted, you can use the show configuration command to verify that the configuration has been rolled back to the previous checkpoint.
