Which domain/layer focuses on the storage and management of data within an enterprise network?

• A. Data Layer
• B. Technology Layer
• C. Environment Layer
• D. Application/Information System Layer

Answer: (A)

Storing and managing data across the enterprise is handled by the Data Layer. This layer houses databases, data models, storage architectures, and processes for data durability, backups, indexing, and governance. It serves as the repository and backbone for data assets used by applications and analytics, ensuring data is organized, consistent, and accessible. The other layers focus on different aspects: the Application/Information System Layer is where software and business processes operate on data, not primarily on its storage; the Technology Layer covers the underlying hardware and platforms that run systems; and the Environment Layer encompasses policies, risk considerations, and external conditions that affect how systems are managed.
