Which domain/layer focuses on organizational and operational aspects when architecting an enterprise network?

• A. Business Layer
• B. Environment Layer
• C. Technology Layer
• D. Data Layer

Answer: (A)

The Business Layer focuses on organizational and operational aspects when architecting an enterprise network. It translates business goals into network requirements, governs policies and compliance, defines service levels, roles, responsibilities, budgeting, and change management, and ensures the network enables day-to-day operations across the enterprise. This alignment with strategy, governance, and operations is what makes it the best fit for addressing how the network supports the organization as a whole. The other layers handle different concerns: the Environment Layer deals with physical hosting, facilities, and site-specific factors; the Technology Layer covers network devices, protocols, and configurations; the Data Layer focuses on data assets and how data moves and is stored.
