Which command is used to clear the current configuration in FortiGate?

The command that is used to clear the current configuration in FortiGate is "execute factoryreset." This command restores the device to its factory default settings, which means that all configurations, including interfaces, policies, VPN settings, and any custom settings that were made will be completely erased. This is particularly useful in situations where a fresh start is necessary, either when redeploying the device or resolving complex configuration issues.

Other commands mentioned might relate to specific functions, but they do not clear the entire configuration in the same way. For instance, "reset system" might pertain to resetting certain system parameters without removing all configurations, while "clear config" and "delete config" are not recognized commands in the context of FortiGate devices. Therefore, the choice "execute factoryreset" is the most accurate and effective command for resetting FortiGate to its original configuration state.
