SG0-001 · Question #17

Which of the following Fibre Channel feature allows Virtual Machines to be seen individual^ on the fabric?

The correct answer is C. NPIV. NPIV (N-Port ID Virtualization) is a Fibre Channel feature that allows multiple Fibre Channel N_Port IDs to share a single physical N_Port. This enables individual virtual machines to have their own unique World Wide Port Name (WWPN) on the fabric, appearing as distinct entities

Why each option

NPIV (N-Port ID Virtualization) is a Fibre Channel feature that allows multiple Fibre Channel N_Port IDs to share a single physical N_Port. This enables individual virtual machines to have their own unique World Wide Port Name (WWPN) on the fabric, appearing as distinct entities to the SAN.

AVLAN

VLANs are used for network segmentation in Ethernet environments, not for virtualizing Fibre Channel N_Port IDs.

BVirtual Fabric

Virtual Fabric often refers to zoning or logical partitioning within a Fibre Channel switch, not the virtualization of N_Port IDs for individual VMs.

CNPIVCorrect

NPIV (N-Port ID Virtualization) is a Fibre Channel feature that allows a single physical HBA port to register multiple N_Port IDs with the fabric. This functionality enables each virtual machine to have its own unique World Wide Port Name (WWPN), making them individually addressable and manageable on the Fibre Channel SAN.

DVirtual Storage

Virtual Storage is a broad term for abstracting storage resources, but it doesn't specifically describe the Fibre Channel feature that allows VMs to be individually visible.
