To prevent non-ESXi hosts from seeing VMFS datastores, which would be the most efficient place to configure LUN masking?
A. On the ESXi host
B. On the SAN Storage Device
C. On the non-ESXi hosts
D. On the Fibre Channel Switch
Correct Answer: B
Explanation/Reference:
Zoning and Lun Masking are often confused for each other probably because both of them are used to restrict access to storage. If you want to specify only certain hosts from accessing a storage device then you would want to setup zoning. Once the zoning is done, we can further lock down access to the storage by setting up LUN (Logical Unit Number) Masking on the storage device.
