Which port number is assigned to iSCSI?

• A. 3260
• B. 860
• C. 443
• D. 21

Answer: (B)

iSCSI carries SCSI block commands over TCP/IP and is designed to use a specific default port so initiators and targets can easily locate each other. The standard port for iSCSI is 3260. This is the port most implementations listen on by default, and it’s what you’d configure in firewalls and network ACLs when setting up an iSCSI target or initiator. Some environments can be configured to use a non-standard port, but 3260 remains the conventional default. The other ports listed correspond to different services: 443 is HTTPS, 21 is FTP, and 860 isn’t a standard iSCSI port.
