Answer: C - The protocol used for securing ISCSI sessions to a remote target is CHAP (Challenge Handshake Authentication Protocol). IP networks do not secure data in flight; this can be a security risk for storage traffic, as a network sniffer could be used to capture packets of data. One way of securing a storage session between a source and target is to use the CHAP method. This allows a set of credentials to be used to secure communication.
