NetApp Certified Implementation Engineer – SAN, E-Series — Question 17

Which security method would be used to authenticate targets and initiators in an ISCSI environment?

Answer options

• A. CHAP
• B. LDAP
• C. NIS
• D. /etc/hosts

Correct answer: A

Explanation

CHAP (Challenge Handshake Authentication Protocol) is specifically designed for authenticating users in network protocols, including ISCSI. LDAP (Lightweight Directory Access Protocol) and NIS (Network Information Service) are directory services, not authentication methods for ISCSI. The /etc/hosts file is used for hostname resolution and does not provide authentication.
