Answer: B

Explanation:

NFS (Network File System) is a distributed file system protocol that allows users on client computers to access files over a network in a manner similar to how local storage is accessed. NFS uses a Kerberos-based security model to provide authentication, integrity, and confidentiality of data. It ensures that unauthorized users do not have access and protects the data from eavesdropping and tampering as it moves across the network. The other options are not features of NFS. Role-based access control is a method of restricting access to resources based on the roles of users. Block-based file access is a type of storage access that transfers data in fixed-sized blocks. Zone-based access control is a feature of Fibre Channel SANs that allows traffic isolation within a VSAN.
