An organization wants to deploy a block storage in the cloud using a storage array that is accessible through the iSCSI protocol. The hosts support iSCSI.
Why would network segmentation be included in the design to support this requirement?
A. Secure all traffic between the storage array and the hosts
B. Enable CHAP between the array and hosts
C. iSCSI traffic is not supported on networks with other types of traffic
D. Enable LUN masking capabilities of the array
Correct Answer: D
Explanation/Reference:
LUN masking is a further constraint added to LUN zoning to ensure that only devices authorized to access a specific server can access the corresponding port.
A logical unit number (LUN) is a unique identifier that designates individual hard disk devices or grouped devices for address by a protocol associated with a SCSI, iSCSI, Fibre Channel (FC) or similar interface. LUNs are central to the management of block storage arrays shared over a storage area network (SAN).
