Exam 98-365 topic 1 question 204 discussion

An Internet Small Computer System Interface (iSCSI) initiator is software or hardware that enables a host computer to send data to an external iSCSI-based storage array through an Ethernet network adapter over a Transmission Control Protocol (TCP)-based Internet Protocol (IP) network. A Storage Area Network (SAN) is a specialized, high-speed network that provides block-level network access to storage. SANs are typically composed of hosts, switches, storage elements, and storage devices that are interconnected using a variety of technologies, topologies, and protocols. SANs may also span multiple sites. A SAN presents storage devices to a host such that the storage appears to be locally attached. This simplified presentation of storage to a host is accomplished through the use of different types of virtualization.

iSCSI authentication methods are: Challenge Handshake Authentication Protocol (CHAP)—The initiator logs in using a CHAP user name and password.You can specify a CHAP password or generate a hexadecimal secret password. There are two types of CHAP user names and passwords: Inbound—The storage system authenticates the initiator. Inbound settings are required if you are using CHAP authentication. IPSec is an IP layer-based security protocol, which is in contrast to other security protocols like SSL that operate at the application layer of the OSI model. NOTE: it is not an authentication method like the question asks but a security encrypting protocol. Answer should just be CHAP
