What is the implication if a user is logged in during restricted hours?

If a user is logged in during restricted hours, the implication is that the user cannot start new sessions. This is designed to control access to the system at specific times to maintain security and operational integrity.

When a user is already logged in, their current session remains active; however, they are restricted from initiating new actions that require a separate login or session. This measure ensures that users who are logged in prior to the enforcement of restricted hours are not able to begin new activities that could conflict with the operational policies in place during these periods.

The other scenarios do not accurately align with the function of restricted hours. Users may not necessarily need to log out immediately or will lose unsaved work simply because they are active during a restricted period. Additionally, while warning notifications may be appropriate in some contexts, the primary restriction imposed during restricted hours is specifically about starting new sessions, making option A the most relevant choice in this context.
