解説

問 40

ア
正解 A Service Level Agreement (SLA) is a document in which the quality level of the provided service is written out and agreed upon as numeric targets between the operations side (the service provider) and the user side (the customer). The condition in the question, “recovery from a failure shall be completed within 3 hours”, is a measurable service-quality target, namely the recovery time, and it is exactly the kind of item an SLA stipulates. Therefore choice ア is correct.
Incorrectイ
A software detailed design document is a development-phase deliverable that describes, for developers, the internal structure of the program (module composition, processing logic, data structures, and so on); it is not a document in which the operations side and the user side agree on service quality.
Incorrectウ
A Request for Proposal (RFP) is a document in which the ordering party presents the system requirements and procurement conditions to vendors and requests proposals. It is used at the entry point of procurement; it is not a document in which the operations side and the user side agree on the service quality level after operations begin.
Incorrectエ
A project charter is a document that formally defines the project's purpose, objectives, organizational structure, and responsible persons, and authorizes the project launch. It is a project-management initiation document; it is not a document that stipulates service quality such as failure recovery time.

ここがポイント

An SLA (Service Level Agreement) is a document in which service-quality levels such as recovery time, availability, and response time are agreed upon as numeric targets between the provider and the user.
Do not confuse similar documents: an RFP is a request for proposals at the procurement stage, a detailed design document is a development deliverable, and a project charter is a launch-authorization document; each plays a different role.
