What are two functions of zoning in fibre Channel switches? (Choose two)
A.
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.
Reduces the number of targets and LUNs presented by a Fibre Channel storage array

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.
