解説
問 39
- ア
正解 A service's warranty means the quality of keeping the service in a state where it can always be used without problems — availability, reliability, continuity, security, and so on. Choice ア, “It is available 24 hours a day, 365 days a year,” means the service is always running, which is availability itself, so it is exactly the warranty. The stem also defines warranty as “the service warranty that maintains availability and the like,” which matches ア.
Incorrectイ
“It can work together with other software such as games” describes what the service can do — that is, its function (utility) — not the warranty that maintains availability.
Incorrectウ
“It can be used free of charge” is a description about price (cost); it corresponds to “price” among the three elements, not the warranty.
Incorrectエ
“You can also use icons that you have created yourself” describes what the user can do — that is, the function (utility) — not the warranty that maintains availability.
ここがポイント
- The value of an IT service increases through the balance of three things: price (cost), function (utility = what it can do), and warranty (maintaining a usable state). Warranty refers to qualities such as availability, reliability, continuity, and security.
- A description of operating rate or availability such as “available 24 hours a day, 365 days a year” is a typical example of warranty. Do not confuse it with descriptions like rich functionality or being free of charge.
