A Hitachi Unified Storage (HUS) system has been configured to use additional Host Groups. Which host interface type on the HUS can be used to access these Host Groups?

Explanation

FC (Fibre Channel) is the correct answer because Host Groups in HUS are a Fibre Channel-specific construct used to organize FC-attached hosts and control LUN access (LUN masking). Host Groups map directly to FC ports on the HUS and define which hosts can see which volumes.

Why the distractors are wrong:

• iSCSI (B): iSCSI manages host access through initiator IQN names and CHAP authentication, not Host Groups - it uses a different access control model.
• NAS (C): NAS operates at the file level (NFS/CIFS), not the block level; Host Groups are a block storage concept and have no relevance to NAS protocol access.
• IP (D): IP is a generic network layer, not a specific host interface type on HUS. While iSCSI travels over IP, "IP" alone is not a valid block storage host interface designation in this context.

Memory tip: Think "FC = Host Groups" - in Hitachi storage, Host Groups live on FC ports and are the gatekeeper for FC-attached hosts. If you see "Host Group" on an HUS, immediately think Fibre Channel.
