SK0-004 · Question #261
Which of the following is a storage system that can be connected to multiple servers through an iSCSI connection?
The correct answer is D. SAN. A SAN (Storage Area Network) supports iSCSI as a transport protocol, enabling block-level storage to be shared across multiple servers over an IP network.

Why each option
A SAN (Storage Area Network) supports iSCSI as a transport protocol, enabling block-level storage to be shared across multiple servers over an IP network.
JBOD is a direct-attached collection of drives with no built-in network sharing capability over iSCSI or any other protocol.
DAS is physically cabled to a single server and provides no mechanism for iSCSI or network-based sharing to multiple servers.
NAS provides file-level sharing over IP using NFS or SMB, not block-level access via iSCSI.
A SAN can use iSCSI (Internet Small Computer Systems Interface) to encapsulate SCSI commands within TCP/IP packets, allowing multiple servers to access shared block-level storage over standard Ethernet infrastructure. iSCSI is a primary SAN protocol alongside Fibre Channel, and the ability to serve multiple servers with block storage is the defining SAN trait.
