Maintenance mode requires all of these actions except:

The correct answer highlights the action that is not a requirement during maintenance mode. Maintenance mode typically implies that a system is in a controlled state where modifications and updates can be carried out safely without affecting normal operations.

Removing all active production instances is often necessary to prevent any disruptions or conflicts while maintenance is being performed. Preventing new logins is also essential to avoid any user activity that could interfere with the processes being applied during maintenance. Ensuring that logging continues is crucial for tracking any changes made during this time, allowing for accountability and troubleshooting should any issues arise.

Initiating enhanced security controls, while important in many contexts, is not universally required during maintenance mode. In some cases, the focus is more on maintaining existing security policies rather than adding additional layers, which may not be feasible or necessary when the system is being serviced. Therefore, the answer is correct in identifying that enhanced security controls are not a mandatory action during maintenance mode.
