A BIG-IP Administrator needs to apply a license to the BIG-IP system to increase the user count from the base license. Which steps should the BIG-IP Administrator?

To add new features or increase existing license entitlements like user count without fully replacing the base license, the 'Re-activate' option under 'System > License' is used, specifically selecting 'Add-On Registration' to incorporate the new license key parts. This allows the BIG-IP system to update its licensing information to reflect the increased capacity.

'Base Registration' is used for the initial licensing of a new BIG-IP system or a complete license replacement, not for adding features or increasing counts to an existing base license.

'Device Management > Devices' is used for managing properties of BIG-IP devices in a high-availability pair or device group, not for applying new license features.

'System > Configuration > Device > General' is for setting basic system-wide device properties like host name or time zone, not for managing license additions.
