Which information can the administrator use to identify iSCSI nodes?
The correct answer is B. IQN. iSCSI nodes - both initiators and targets - are uniquely identified by their IQN (iSCSI Qualified Name), the standard naming convention defined for the iSCSI protocol.

Why each option
iSCSI nodes - both initiators and targets - are uniquely identified by their IQN (iSCSI Qualified Name), the standard naming convention defined for the iSCSI protocol.
MAC addresses identify network interface cards at Layer 2 of the OSI model and are not used to identify or name iSCSI nodes or sessions.
The IQN (iSCSI Qualified Name) is the standard node identifier defined by RFC 3720 for iSCSI, following the format 'iqn.yyyy-mm.reversed-domain:unique-string'. It uniquely identifies each iSCSI initiator (such as an ESXi host's software iSCSI adapter) and each iSCSI target (storage array port) within the storage network, enabling proper node discovery and session establishment.
WWN (World Wide Name) is the node identifier used in Fibre Channel and FCoE storage networks, not in iSCSI environments.
A LUN ID identifies a specific logical unit of storage presented by a target, not the iSCSI node (initiator or target) itself.
