SG0-001 · Question #299

Click the Exhibit button. Servers in your environment are connected to one physical infrastructure which consists of different logical fabrics. Which feature do you use to implement this topology?

The correct answer is B. Virtual Fabric. To create multiple isolated logical fabrics within a single physical Fibre Channel infrastructure, the Virtual Fabric feature is used.

Why each option

To create multiple isolated logical fabrics within a single physical Fibre Channel infrastructure, the Virtual Fabric feature is used.

ANPIV

NPIV (N_Port ID Virtualization) allows a single physical HBA port to register multiple N_Port IDs with the fabric, primarily for virtualization, but it does not create separate logical fabrics.

BVirtual FabricCorrect

Virtual Fabrics, also known as logical switches or VSANs (Virtual Storage Area Networks), allow a single physical Fibre Channel switch or infrastructure to be partitioned into multiple isolated logical fabrics, enabling consolidation while maintaining separation for different server groups or applications.

CZoning

Zoning is a security mechanism that restricts communication between devices within a single fabric, defining which devices can see each other, but it does not create distinct logical fabrics.

DSegmentation

Segmentation is a general networking term for dividing networks; however, in Fibre Channel, 'Virtual Fabric' or 'VSAN' is the specific feature for implementing isolated logical fabrics on shared physical hardware.
