Which is a consequence of unplanned application deprovisioning?

The correct choice highlights that all user access can be removed when an application is unplanned for deprovisioning. This can lead to immediate and comprehensive removal of access rights for all users associated with that application. It is a crucial aspect of identity and access management since unplanned deprovisioning typically occurs when an application is no longer needed, is deprecated, or poses security risks. Ensuring that all access rights are removed effectively helps mitigate risks by preventing unauthorized access to data and resources.

In contrast, the other options focus on scenarios or outcomes that do not directly relate to the consequences of unplanned deprovisioning. While increased user licenses available could happen post-deprovisioning, it does not directly address the consequences of unplanned removal. New user notifications and request access capabilities typically involve operational processes outside the context of unplanned deprovisioning and do not capture the immediate implications of losing access altogether.
