The system administrator wants to ensure that the ability to change passwords is disabled in the BIOS. Which method can be used to achieve this?

Dell PowerEdge servers are equipped with a password jumper (commonly labeled PWRDEN or PSWDEN) on the system board. By changing the position of this jumper, an administrator can enable or disable the password functionality at a hardware level. When the jumper is set to the disabled position, the ability to set, change, or delete the system and setup passwords within the System Setup (BIOS/UEFI) utility is prevented. This acts as a physical security measure to lock the password configuration.

B. The System ID button is used for physical server identification within a data center rack, typically by activating LED indicators.
C. Managing iDRAC users pertains to remote management access and its security, which is separate from the local system BIOS password settings.
D. The System Setup utility is the interface used to change the password; it cannot be used to disable the ability to make changes itself.
