Which protocol allows a system to use block-level storage as if it was a SAN, but over TCP network traffic instead?
Answer options:
A. SATA
B. iSCSI
C. TLS
D. SCSI
Answer correct:
B
iSCSI is a protocol that allows for the transmission and use of SCSI commands and features over a TCP-based network. iSCSI allows systems to use block-level storage that looks and behaves as a SAN would with physical servers, but to leverage the TCP network within a virtualized environment and cloud.
