Which service roles are added for enabling DFS?

The inclusion of the DFS Namespace and DFS Replication roles is essential for enabling Distributed File System (DFS) functionality. DFS is designed to improve the availability and management of shared folders in a networked environment.

The DFS Namespace role allows administrators to create a unified namespace for accessing different shared folders located across multiple servers. This means that users can access folders from various locations under a single directory structure, simplifying navigation and improving user experience. On the other hand, the DFS Replication role ensures that data within these shared folders is synchronized between servers, enhancing data availability and redundancy. This replication process allows files to be kept up-to-date across different servers, making it easier for organizations to manage their file-sharing needs while ensuring that users have access to the most current data.

The other choices relate to functions that do not specifically enable DFS itself. While file sharing roles and file server roles involve sharing files and resources across the network, they do not encompass the unique capabilities of DFS Namespace or DFS Replication. Storage management roles typically focus on provisioning and managing storage resources, which again does not directly correlate with the enabling of DFS functionality. Therefore, the correct answer highlights both key roles necessary for implementing and utilizing DFS effectively.
