Which of the following name services is used to provide initiators with discovery information?

NIS (Network Information Service) is a distributed directory service for system configuration data like user and host names, not for storage target discovery.

DNS (Domain Name System) translates human-readable domain names into IP addresses and vice-versa, but it is not specifically designed for the discovery of iSCSI or FCoE storage targets.

DDNS (Dynamic DNS) is an extension of DNS that automatically updates IP address information for hosts, but it still serves the primary function of name-to-IP resolution, not storage target discovery.

iSNS (Internet Storage Name Service) provides a central registration and discovery service for iSCSI and Fibre Channel over Ethernet (FCoE) devices. Initiators query the iSNS server to discover available targets and their network addresses, simplifying the configuration and management of large storage area networks (SANs).
