You are the Chief Enterprise Architect of Stella Maris Investments which acquired a huge enterprise network infrastructure three years ago. Since the acquisition, the organization has been running two parallel networks. It has now decided to streamline and align its operations and processes by consolidating the two networks into one functional state-of-the-art network infrastructure for efficiency, high productivity, and stable growth. This entails redesigning the organizations existing enterprise network architecture to accommodate the acquired network.
