IPA IP 2021 Question 57
A question IPA Japan published in 令和3年度 ITパスポート試験 公開問題 問57, translated into English. ITPEC is based on the same exams.
Same question on ITPEC: Apr 2025 Q23
Which of the following is a space-saving server where computer components including the CPU, main memory, and storage are installed on a single circuit board and multiple circuit boards are mounted in racks?
Explanation
Blade server — many thin server boards, each a complete computer, mounted in one rack chassis.
Each blade carries its own CPU, main memory and storage on a single board and slides into a slot of a chassis. The chassis supplies what the blades share: power, cooling fans, network connections and management. Compared with the same number of stand-alone servers this saves rack space and cabling, and blades can be added or swapped one at a time.
Answer (d)
Why not others:
- •(a) DNS server — a role: it translates domain names into IP addresses
- •(b) FTP server — a role: it sends and receives files with the FTP protocol
- •(c) Web server — a role: it delivers web pages to browsers over HTTP
All three name the service a server provides, and each can run on a blade, a tower or a virtual machine; none describes the board-in-rack construction.
Key rule: Blade, rack-mount and tower describe a server's physical form; DNS, FTP, web and mail describe the service it runs, and one machine can host several services.
