Which statement about NFS is correct?

NFS, or Network File System, is designed to allow multiple clients to access files over a network in a shared manner. The statement that it supports multi-user access is correct because NFS enables numerous clients to connect to a single file system, allowing users on different machines to read from and write to shared files seamlessly. This is accomplished through a client-server model where the NFS server exports directories and files, and clients can mount those shared resources, providing an effective way to facilitate collaboration and access in a multi-user environment.

In contrast, other statements may not accurately reflect the characteristics of NFS. For instance, while users can access shared resources, there are specific permission settings involved in its operation, and the protocol is generally considered stateless because each request from a client is processed independently without keeping track of the client's state between requests. Thus, the recognition of NFS as a multi-user access system emphasizes its robust capabilities for file sharing in environments where numerous users need to interact with the same data simultaneously.
