Which of the following is NOT included in distributed storage networking?

• A. Frontend storage network
• B. Backend storage network
• C. Management network
• D. Frontend service network

Answer: (A)

In distributed storage networking, traffic is typically organized into distinct paths: the backend storage network for inter-node data I/O and replication, the management network for administration and monitoring, and the frontend service network that handles client-facing service endpoints through gateways. A term like frontend storage network isn’t a standard, well-defined segment in this architecture—the client requests are usually served via a gateway or service layer rather than a separate internal storage network fabric. Therefore, the concept that is not part of distributed storage networking is the frontend storage network. The backend storage network and the management network are essential components for data flow and control, and a frontend service network supports client access through exposed services.
