SG0-001 · Question #145
Which of the following technologies enables a single HBA to be used by multiple virtual machines with each one addressed independently on a SAN?
The correct answer is A. NPIV. N_Port ID Virtualization (NPIV) enables a single physical HBA port to register multiple virtual N_Port IDs with a Fibre Channel switch, allowing individual virtual machines to appear as independent initiators on the SAN.

Why each option
N_Port ID Virtualization (NPIV) enables a single physical HBA port to register multiple virtual N_Port IDs with a Fibre Channel switch, allowing individual virtual machines to appear as independent initiators on the SAN.
NPIV allows a single physical Fibre Channel HBA port to register multiple N_Port IDs (WWNs) with a Fibre Channel switch, enabling each virtual machine connected to that HBA to have its own unique virtual WWN and be addressed independently on the SAN.
VSANs segment a physical SAN into isolated logical SANs, but do not directly enable multiple virtual machines to share a single HBA independently.
LVM is a host-based disk management technology that aggregates physical storage into logical volumes, unrelated to HBA sharing for virtual machines on a SAN.
VLANs segment IP networks into logical broadcast domains and are not used in Fibre Channel SAN environments for HBA sharing.
