220-1101 Question #324: Real Exam Question with Answer & Explanation

Question

A technician is building a new computer for a customer. The computer must use an ITX-sized motherboard and have a RAID 5 array with all drives using the same interface. Which of the following drive types will the technician MOST likely utilize?

Options

• ASCSI
• BPCIe
• CNVMe
• DSATA

Explanation

For an ITX motherboard with a RAID 5 array using drives of the same interface, SATA drives are the most common and practical choice due to their cost-effectiveness and widespread compatibility.

Common mistakes.

• A. SCSI (Small Computer System Interface) drives are largely legacy in consumer/SOHO desktop builds and would require specialized controllers not typically found on ITX motherboards for a new build.
• B. PCIe is an interface, but "PCIe drives" usually refers to NVMe drives that connect via a PCIe slot or M.2 slot; building a RAID 5 with multiple NVMe drives would be significantly more expensive and complex, and ITX boards have limited PCIe/M.2 slots.
• C. NVMe (Non-Volatile Memory Express) drives offer high performance and typically connect via PCIe/M.2 slots, but an ITX motherboard would usually have only one or two M.2 slots, making it impractical and costly to build a RAID 5 with multiple NVMe drives compared to SATA.
