Controls and isolates LUNs on a Fibre Channel storage array

B.
Restrict connections on a storage array to ESXi hosts that use the array

C.
Prevents non-ESXi hosts from possibly destroying VMFS data

D.

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.

    Coreect answers are B & C. Zoning is done on the switch and only affect connectivity. It does not control anything on the storage array.
