CompTIA A+ 220-1101 Practice Question

Answer Description

The correct answer is the Molex connector because this type of power connector is commonly used to supply power to older hard disk drives, optical drives, and other internal components that require a four-pin power connection. The SATA power connector, while also used for hard drives, is a flat 15-pin connector and would not fit the four-pin requirement. The USB-C and RJ45 connectors are not used for providing power to internal hard disk drives; USB-C is primarily used for data transfer and peripheral connectivity, and RJ45 is for network cabling.
