What are two use cases for Fibre Channel Zoning in a vSphere environment? (Choose two.)

B. Controls and isolates paths in a fabric.
C. Controls and isolates paths to an NFS share.
D. Can be used to separate different environments.
Correct Answer: BD

Explanation : Using Zoning with Fibre Channel SANs
Zoning provides access control in the SAN topology. Zoning defines which HBAs can connect to which targets. When you configure a SAN by using zoning, the devices outside a zone are not visible to the devices inside the zone.
Zoning has the following effects:
Reduces the number of targets and LUNs presented to a host.
Controls and isolates paths in a fabric.
Can prevent non-ESXi systems from accessing a particular storage system, and from possibly destroying VMFS data. Can be used to separate different environments, for example, a test from a production environment.
