Show Suggested Answer Hide Answer
Suggested Answer: 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.

B is the correct answer. https://www.techtarget.com/searchstorage/definition/iSCSI How iSCSI works ISCSI works by transporting block-level data between an iSCSI initiator on a server and an iSCSI target on a storage device. The iSCSI protocol encapsulates SCSI commands and assembles the data in packets for the TCP/IP layer. Packets are sent over the network using a point-to-point connection. Upon arrival, the iSCSI protocol disassembles the packets, separating the SCSI commands so the operating system (OS) will see the storage as if it was a locally connected SCSI device that can be formatted as usual.
