Which three are HDD interface types? (Choose three.)

Question

Options

• AInternal Advanced Terminal Interface (IATA)
• BSmall Computer Systems Interface (SCSI)
• CSerial Advanced Technology Attachment (SATA)
• DInternet Small Computer System Interface (iSCSI)
• EParallel Advanced Technology Attachment (PATA)

• A
  3% (1)
• B
  90% (27)
• D
  7% (2)

Explanation

SCSI, SATA, and PATA are all established physical interface standards used to connect hard disk drives to a computer's motherboard or controller, which is why B, C, and E are correct. PATA (also known as IDE) was the dominant standard before being succeeded by SATA, while SCSI has long been used in enterprise and server environments.

Option A (IATA) is a fabricated distractor - "IATA" is the International Air Transport Association, not a computer interface standard; no such HDD interface exists.

Option D (iSCSI) is the tricky one: while it builds on SCSI, the "i" stands for "Internet," meaning it tunnels SCSI commands over a TCP/IP network. It's a network storage protocol (used in SANs), not a physical drive interface type.

Memory tip: Focus on the word "Internet" in iSCSI - if it travels over a network, it's not a local drive interface. For the three correct answers, remember the progression: PATA (old) → SATA (modern consumer) → SCSI (enterprise).
