300-320 Question #351: Real Exam Question with Answer & Explanation

The correct answer is B: VSANs have their own set of services and address space, which prevents an issue in one VSAN. B is correct: VSANs maintain their own independent set of Fibre Channel services (name server, login server, etc.) and their own address space. A fabric event or disruption in one VSAN is isolated and cannot propagate to another VSAN, providing fault isolation between tenants. E

Question

When designing data centers for multitenancy, which two benefits are provided by the implementation of VSAN and zoning? (choose two)

Options

AVSAN provides a means of restricting visibility and connectivity among devices connected to a
BVSANs have their own set of services and address space, which prevents an issue in one VSAN
CZones provide the ability to create many logical SAN fabrics on a single Cisco MDS 9100 family
DVSANs and zones use separate fabrics
EZones allow an administrator to control which initiators can see which targets

Explanation

B is correct: VSANs maintain their own independent set of Fibre Channel services (name server, login server, etc.) and their own address space. A fabric event or disruption in one VSAN is isolated and cannot propagate to another VSAN, providing fault isolation between tenants. E is correct: Zoning operates within a VSAN and controls which initiators (HBAs on servers) can see and communicate with which targets (storage ports), enforcing access control at the LUN visibility level. Together, VSANs provide multi-tenant fabric segmentation and zones provide fine-grained access control within each segment.
