Which statement accurately describes the location of the motherboard tray in the chassis of the...

In Supermicro’s SYS-421GE-TNHR2-LCC, the motherboard tray isbelow the PCIe tray, consistent with high-end server designs (e.g., SYS-420GP-TNAR). The motherboard tray houses CPUs and core components, while the PCIe tray (often with GPUs) sits above, connected via risers or direct slots. Options C and D reference a “GPU tray,” likely a misnomer for the PCIe tray, but B remains accurate. Supermicro’s DLC systems stack trays vertically for cooling efficiency, confirming B as correct.References:Supermicro chassis layout specs, DLC system tray configurations.
