Which CHAP authentication mechanisms are only available when using software and dependent hardware iSCSI adapters (Choose Two)?
ESXi supports the following CHAP authentication methods:
In one-way CHAP authentication, also called unidirectional, the target authenticates the initiator, but the initiator does not authenticate the target.
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.
