To enable NFS client networking on Red Hat 7, which packages should be installed?

• A. yum install rpcbind nfs-utils
• B. yum install nfs-utils nsflock rpcbind
• C. yum install nfs-tools
• D. yum install nfs-kernel-server

Answer: (B)

Enabling NFS client networking on Red Hat 7 requires the user-space utilities to manage NFS shares, the RPC service mapping, and the locking support used by NFS. The nfs-utils package provides the tools to mount and interact with NFS servers. The rpcbind package handles RPC program number mapping so the client can contact NFS services (including the lock manager) on the server. The nsflock package supplies the NFS locking daemon support, which is important for proper file locking over NFS. Together, these ensure the client can mount NFS shares, communicate with the server, and perform file locking as needed. The other options don’t cover all of these client-side components: some are server-focused, some are not the correct package for Red Hat 7, and others omit essential client functionality.
