The correct answer is A. Zoning. To control which Fibre Channel devices can communicate and allow a server to access its allocated storage, an administrator configures zoning on the Fibre Channel switch. Zoning uses WWNNs to create logical groups of devices that are permitted to interact.

Question

A new server is connected to the fibre channel switch. In order to allow the server to see its allocated storage on the storage array, the administrator must configure the server's WWNN as a member. The server administrator is configuring which of the following?

Why each option

To control which Fibre Channel devices can communicate and allow a server to access its allocated storage, an administrator configures zoning on the Fibre Channel switch. Zoning uses WWNNs to create logical groups of devices that are permitted to interact.

AZoningCorrect

Zoning in Fibre Channel environments creates logical partitions (zones) on a Fibre Channel switch, which restrict device-to-device communication. By adding a server's World Wide Node Name (WWNN) to a zone with specific storage ports, the administrator ensures that the server can discover and access its dedicated storage LUNs on the storage array.

BLUN masking

LUN masking is performed on the storage array itself to restrict which servers can see specific Logical Unit Numbers (LUNs), rather than on the Fibre Channel switch based on WWNN membership.

CSupernetting

Supernetting is a networking technique used in IP-based networks to combine multiple smaller IP networks into a larger one, and it is unrelated to Fibre Channel storage connectivity.

DVLAN tagging

VLAN tagging is used in Ethernet networks to segment network traffic into virtual local area networks, which is not applicable to Fibre Channel storage networks.
