Why each option

The question asks for the process of establishing logical communication paths between devices in a Fibre Channel fabric using their Worldwide Names (WWNs).

AMasking

Masking, specifically LUN masking, controls which host can access which Logical Unit Numbers (LUNs) on a storage array, not the WWN-based logical connections in a fabric.

BSharing

Sharing is a general term and not the specific technical process for creating logical connections between WWNs in a fabric.

CZoningCorrect

Zoning is the method used in Fibre Channel fabrics to create logical groups of devices (initiators and targets) that can communicate with each other, effectively controlling access and visibility based on WWNs, ports, or fabrics. This segmentation prevents unauthorized access and improves security and manageability within the SAN.

DMounting

Mounting is the process by which an operating system makes a storage device or file system accessible, typically from a server perspective, and is not related to fabric-level WWN connections.
