What should the BIG-IP Administrator do to apply and activate a hotfix to a BIG-IP device that is currently running version 11.0.0 on active partition HD1.1?

Before installing a hotfix, it is best practice to target an inactive boot partition (like HD1.2) that already contains the base BIG-IP version (11.0.0 in this case) for which the hotfix is intended. The hotfix will then be applied to that specific installation on HD1.2, allowing for a clean upgrade path and an easy rollback if needed.

Reactivating the license on the currently active partition HD1.1 is not the first step for applying a hotfix to a *different* partition.

Activating partition HD1.2 is a later step, performed *after* the hotfix has been successfully installed onto that partition, to make the new software version active.

Setting partition HD1.2 active is functionally the same as activating it and is done *after* the hotfix installation, not as the initial step.
