About this MCQ
This Hard Memory & Storage MCQ checks one syllabus fact.
The question is: “Select the correct name for: a data storage technology that combines multiple physical drives for redundancy or performance.”
The accepted answer is B. RAID. “Select the correct name for: a data storage technology that combines multiple physical drives for redundancy or performance.” is answered by RAID (option B). Option A (“Secondary storage”) does not match the stem; it is a near-miss used to catch incomplete recall of RAID. Option C (“Memory buffer”) does not match the stem; it is a near-miss used to catch incomplete recall of RAID. Remaining alternatives (SSD write endurance) fall outside the same rule and should be eliminated once RAID is identified. Memory & Storage questions of this type reward precise definitions rather than approximate associations. Memory & Storage recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
