Which of the following describes the main purpose of the Management Network?

The main purpose of the Management Network is indeed to manage cluster administration tasks. This network is specifically designed to allow administrators to perform various management functions, such as configuration, monitoring, and overall management of the storage systems. The Management Network typically handles administrative traffic, enabling smooth communication regarding system health, updates, and configuration changes.

In this context, it's important to note that the other options do not align with the primary role of the Management Network. For instance, while data replication, client data access, and backup processes are crucial for a storage environment, these functions typically rely on different networks or segments optimized for data transfer rather than the administrative tasks that the Management Network handles.
