Which is the most secure method of connecting to an iSCSI storage array using an independent hardware iSCSI adapter?
A. One-way CHAP
B. Mutual CHAP
C. Per-target CHAP
D. Per-subnet CHAP
Correct Answer: A
Explanation/Reference:
One-way CHAP
In one-way CHAP authentication, also called unidirectional, the target authenticates the initiator, but the initiator does not authenticate the target.
Mutual CHAP
In mutual CHAP authentication, also called bidirectional, an additional level of security enables the initiator to authenticate the target. VMware supports this method for software and dependent hardware iSCSI adapters only.
