To meet the requirements while adhering to the principle of least privilege, each user must be assigned to the group that grants the necessary permissions with the fewest additional privileges. User1: Requires the ability to change the system date and time. This action is governed by the "Change the system time" user right. By default in Windows, both the Administrators and Power Users groups have this right. To apply the principle of least privilege, Power Users is the correct choice as it has significantly fewer permissions than the Administrators group. User2: Requires the ability to clear Windows logs. This is a high-privilege task controlled by the "Manage auditing and security log" user right. Of the groups listed, only the Administrators group holds this right by default. The Event Log Readers group can only read logs, not modify or clear them. Incorrect Options: Administrators (for User1): While members of the Administrators group can change the system time, this group provides full control over the system. Assigning User1 to this group would grant excessive permissions, violating the principle of least privilege. Event Log Readers (for User2): This group is explicitly designed to allow members to read event logs. It does not grant the necessary permissions to clear or otherwise manage the logs. Performance Log Users: This group allows members to manage performance counters, alerts, and logs. It does not grant permissions to change system time or clear the security event log. System Managed Accounts Group: This is a built-in group used by the operating system to manage Group Managed Service Accounts (gMSAs) and is not intended for assigning permissions to standard user accounts.
