Question 1

Which two primary port authentication protocols are used with VSANs? (Choose two.)

A. ESP
B. CHAP
C. DHCHAP
D. SPAP

 

Answer: B C

Explanation

Two primary port authentication protocols when working with VSANs:

+ Challenge Handshake Authentication Protocol (CHAP): CHAP is the mandatory protocol for iSCCI, as chosen by the Internet Engineering Task Force (IETF). CHAP is based on shared secrets.

+ Diffie-Hellman Challenge Handshake Authentication Protocol (DHCHAP): DHCHAP may be used to authenticate devices connecting to a Fibre Channel switch. By using Fibre Channel authentication, you allow only trusted devices to be added to a fabric. This prevents unauthorized devices from accessing the Fibre Channel switch.
