What feature needs to be properly set to allow consistent password rotation on specified days?

The correct answer is the headstart interval. This feature is designed to ensure that password rotation occurs consistently on predetermined days by allowing a specified period before the actual rotation date. The headstart interval controls when the rotation process begins and helps to streamline the schedule for password changes, reflecting organizational policies or compliance requirements.

By setting the headstart interval appropriately, administrators can manage when users are notified about upcoming password changes or when the system actually initiates the password rotation. This leads to better adherence to security protocols and reduces the risk of password-related issues.

On the other hand, time zone settings may affect when the scheduled rotations are recognized by the system but do not directly control the rotation mechanism itself. The rotation interval pertains to how often passwords should be rotated but must be compatible with the headstart interval to achieve consistency. Access rights, while important for restricting who can change passwords, do not influence the scheduling or frequency of password rotations.
