Which domain/layer focuses on applications and information systems within an enterprise network?

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

Answer: (A)

The key idea is separating responsibilities in an enterprise network by layer, with the Application/Information System Layer specifically handling software applications and the information systems that support business processes. This layer covers the programs, services, and interfaces that users interact with, as well as how these applications access data, integrate with other systems, and present information. It includes things like ERP, CRM, email, and other business apps, along with the logic, workflows, and middleware that tie systems together and ensure secure, usable access to information. The other layers focus on different aspects. The Data Layer is about how data is stored, organized, and retrieved. The Environment Layer deals with the runtime and deployment context in which applications operate. The Technology Layer covers hardware, networks, and platforms that provide the underlying infrastructure. Since the question asks about focusing on applications and information systems within the enterprise, the Application/Information System Layer is the best fit.
