Which of the following storage technologies is IP-based?
Options
- ASCSI
- BDAS
- CFCP
- DNAS
Explanation
iSCSI (Internet SCSI) is the IP-based block storage protocol that encapsulates SCSI commands over TCP/IP, making it the IP-based option among the listed storage technologies.
Common mistakes.
- B. DAS (Direct Attached Storage) connects storage directly to a host via interfaces such as SATA or SAS and does not use an IP network.
- C. FCP (Fibre Channel Protocol) transports SCSI commands over Fibre Channel networks, which is a separate fabric technology and not IP-based.
- D. NAS (Network Attached Storage) is a file-level storage architecture that operates over IP, but it is not the block-level IP storage protocol the question targets.
