Which of the following must a technician create to establish a session between a NAS device and a server?

A file system (such as NFS or SMB/CIFS) must be created on the NAS device to organize and store data, which can then be exported or shared with servers. The server then mounts or maps this shared file system to access the storage over the network.

A zoneset is a Fibre Channel (FC) concept used to control device communication within a Storage Area Network (SAN), which is not applicable to file-level access with NAS devices.

A fabric refers to the interconnected network infrastructure, typically in a SAN environment, and is not something a technician 'creates' to establish a session for NAS; rather, NAS uses a standard IP network.

An alias, in the context of storage networking, usually refers to a user-friendly name for a World Wide Name (WWN) in a Fibre Channel environment, which is irrelevant for NAS file sharing.
