When Lockdown Mode is enabled on an ESXi host, a user with administrative privileges in the Exception User list is allowed to log in to the Direct Console User Interface (DCUI). This capability is essential for maintaining management access while providing an additional layer of security. Lockdown Mode restricts certain user logins to enhance security, but adding specific users to the Exception User list ensures that administrators can still perform necessary tasks directly on the host. This could involve system configuration, troubleshooting, or other management functions that can only be handled via the DCUI in certain scenarios.

The ability to log in to the DCUI while in Lockdown Mode allows for critical interventions when remote management might be ineffective or unavailable, thus ensuring that the administrator can always maintain control over the ESXi host when needed. The other alternatives presented, such as not being able to log in to the DCUI, being limited to only command line access, or performing all administrative tasks, do not accurately reflect the restricted, yet essential, privileges afforded to Exception Users under Lockdown Mode.
