An administrator has just finished physically replacing the system board in a Windows domain controller. Which of the following must be done before booting the server back into Windows?

When a system board is replaced, its BIOS/UEFI settings, including the system clock (time and date), are reset to factory defaults. For a Windows domain controller, accurate time synchronization is critical for Kerberos authentication, Active Directory replication, and overall domain functionality. Therefore, setting the correct time and date in the BIOS is a necessary first step to prevent authentication issues and ensure proper operation of the domain controller.

While firmware updates are generally good practice, updating a SCSI controller's firmware is not an immediate prerequisite for booting a server with a new system board.

Updating the system board's firmware to the latest version is a recommended maintenance task but not strictly 'must be done before booting' for initial functionality, as the board will likely come with a working firmware version.

Configuring IPMI (Intelligent Platform Management Interface) is for out-of-band management and is not essential for the server to boot into Windows and function as a domain controller.
