IPA IP 2026 Question 87
A question IPA Japan published in 令和8年度 ITパスポート試験 公開問題 問87, translated into English. ITPEC is based on the same exams.
Which of the following is an appropriate description of NAS?
Explanation
A storage device connected directly to the network — NAS (Network Attached Storage) is a file server in a box.
A NAS has its own network interface and a small built-in OS, and is plugged into the LAN like any other device rather than into one PC. PCs, smartphones and other devices on the network read and write its files over the network, so it serves as shared storage for a home or office. Many NAS units contain several disks combined with RAID for safety.
Answer (a)
Why not others:
- •(b) — reaching data directly regardless of its position or the order it was written in describes direct (random) access, as opposed to sequential access
- •(c) — managing several disks as one device and spreading data across them for speed and fault tolerance is RAID
- •(d) — the character string that identifies a wireless LAN network is the SSID (ESSID)
Key rule: NAS = storage shared over the LAN as files; RAID = several disks acting as one for speed or redundancy; SSID = the name of a wireless LAN.
