Unlike SAN, iSCSI requires no special _____?

• A. Adapters
• B. Physical Disks
• C. Cabling
• D. PCIE Cards

Answer: (C)

The core idea is how storage traffic is transported. iSCSI sends SCSI commands over an IP network, so it uses the existing Ethernet infrastructure you already have. That means you don’t need special physical cabling beyond standard Ethernet cabling and switches. Traditional SAN using Fibre Channel, on the other hand, relies on Fibre Channel hardware and dedicated FC cabling and switches, which are specific to FC networks. So the standout difference is the cabling requirement: iSCSI doesn't require the unique cabling used by Fibre Channel, while SAN typically does. The other aspects, like adapters or PCIe cards, can vary, but the essential reason is the transport medium—iSCSI piggybacks on ordinary Ethernet cabling rather than requiring FC cabling.
