In iSCSI, what term is established when the host logs into the target?

• A. connection
• B. session
• C. target
• D. initiator

Answer: (B)

When an iSCSI initiator authenticates to a target, a session is created. This session represents the logical conversation between the initiator (host) and the target (storage) and remains active to carry SCSI commands and responses. Under that session, there can be one or more underlying TCP connections used for data transfer, but the overarching state established by the login is the session. The initiator is the client, the target is the storage device, and a connection is simply a transport path within a session. That makes the session the correct term for what’s established on login.
