Which domain/layer focuses on the technological infrastructure and components in an enterprise network?

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

Answer: (A)

Understanding the Technology Layer means focusing on the actual infrastructure that underpins the network: hardware like switches, routers, firewalls, servers, and storage; virtualization platforms and the operating systems that run on them; plus the management and orchestration tools, network topology, protocols, and the security controls at the infrastructure level. This layer provides the foundational environment where data is stored and applications run, shaping capacity, performance, and reliability. In contrast, the Data Layer is about data assets and governance, the Application/Information System Layer about the software applications themselves, and the Environment Layer about physical facilities, power, cooling, and related factors. Since the question asks for the domain that focuses on the technological infrastructure and components, the correct focus is the Technology Layer.
