HP0-J73 · Question #148
A system administrator needs to locate storage resources on an IP network by using an iSCSI initiator to query for a list of targets. What should the administrator use to accomplish this goal?
The correct answer is B. Internet Storage Name Service (iSNS). The iSCSI initiator uses iSNS to discover and query available storage targets on an IP network, functioning as a naming and discovery service for storage resources.

Why each option
The iSCSI initiator uses iSNS to discover and query available storage targets on an IP network, functioning as a naming and discovery service for storage resources.
DNS resolves hostnames to IP addresses for general network resources and is not designed to discover or enumerate iSCSI storage targets.
Internet Storage Name Service (iSNS) provides discovery and management of iSCSI targets on IP networks, allowing an iSCSI initiator to query a centralized iSNS server for a list of available targets. It functions similarly to DNS but is purpose-built for storage resource discovery, registering targets and initiators so they can locate each other across an IP fabric.
LDAP is a directory access protocol used for querying directory services such as Active Directory, not for locating iSCSI storage targets.
Information Transfer Channel (ITC) is not a recognized standard protocol for iSCSI target discovery or storage resource location.
