An administrator is trying to configure Mutual CHAP on a Linux guest. During configuration, the administrator keeps getting an Authentication Failure error.
What should the administrator do to resolve the issue?
A.
Configure the password on the target, leave the client password blank.
B.
Configure the client and target with different passwords.
C.
Configure the client and target with the same password.
D.
Configure the password on the client, leave the target password blank.
Mutual CHAP(Challenge-Handshake Authentication Protocol) is used in Nutanix Unified Storage for secure two-way authentication between an iSCSI initiator (client) and the target (VG in Nutanix).
For successful mutual authentication,both the client and the target must use the same CHAP secret:
The initiator uses this secret to authenticate the target.
The target uses the same secret to authenticate the initiator.
The NCP-US and NUSA course materials clearly state:
“Mutual CHAP requires the same CHAP secret to be configured on both the iSCSI initiator (client) and target. Mismatched secrets will result in authentication failures.”
In this scenario, the error is because the secrets do not match. Setting thesame password on bothresolves the issue.
