A pilot deployment presents block-level storage from a NAS appliance to a hypervisor host over the existing Ethernet network using iSCSI. Which TCP port must remain open on the firewall for the iSCSI initiator to successfully connect to the target?

  1. A2049
  2. B3260
  3. C1521
  4. D3389
Show answer & explanation

Correct answer: B. 3260

iSCSI uses TCP port 3260 by default for communication between initiators and targets. Port 3389 is RDP, 1521 is the default Oracle database listener port, and 2049 is used by NFS.

Why the other options are wrong

  • A. 2049 is used by NFS, a different file-level protocol.
  • C. 1521 is the default Oracle database listener port.
  • D. 3389 is used for Remote Desktop Protocol, unrelated to iSCSI.

iSCSI Port 3260

iSCSI encapsulates SCSI commands over TCP/IP, allowing block storage to be shared over standard Ethernet networks using TCP port 3260.

  • Default iSCSI port: TCP 3260
  • iSCSI provides block-level storage over IP networks
  • Requires initiator (client) and target (storage) configuration

Memory trick: iSCSI knocks on door 3260 to deliver its block of storage.
