A new server connected to a fibre channel switch must see its allocated storage on the storage array. The administrator must configure the server's WWNN as a member. This describes which of the following?

A new server connected to a fibre channel switch must see its allocated storage on the storage array. The administrator must configure the server's WWNN as a member. This describes which of the following?

• A. Zoning
• B. LUN masking
• C. Supernetting
• D. VLAN tagging

Answer: (A)

Zoning in Fibre Channel fabrics controls which devices can talk to each other by grouping WWNs (the unique identifiers of hosts and storage ports) into zones. By configuring the server’s WWNN as a member of a zone that includes the storage array’s ports, you ensure the server can access its allocated storage on that array while other devices outside the zone cannot communicate with it. This selective access is exactly what zoning provides, making the server see its designated storage. LUN masking is about hiding or showing specific storage LUNs to a host after connectivity is established, typically configured on the storage side, and does not govern which devices are allowed to communicate in the fabric. The other options—supernetting and VLAN tagging—relate to IP networking and Ethernet segmentation, not Fibre Channel, so they don’t apply here.
