Mark works as a Network Administrator for NetTech Inc. The company has a Windows Server 2008
domain-based network. The network has a Windows Server 2008 member server that works as a
Routing and Remote Access Server (RRAS). Mark implements Network Access Protection (NAP) for
the network. Mark wants to configure Point-to-Point Protocol (PPP) authentication on the RRAS
server. Which of the following authentication methods should Mark use to accomplish this task?
A.
EAP
B.
CHAP
C.
SPAP
D.
PAP
Explanation:
In a NAP infrastructure, authentication is handled using the Extensible Authentication Protocol
(EAP). Extensible Authentication Protocol (EAP) is an authentication protocol that provides support
for a wide range of authentication methods, such as smart cards, certificates, one-time passwords,
public keys, etc. It is an extension to Point-to-Point Protocol (PPP), which allows the application of
arbitrary authentication mechanisms for the validation of a PPP connection.Answer C, D, and B are incorrect. The use of PAP, SPAP, and CHAP is not recommended unless it is
required. Microsoft recommends using only the strongest authentication protocols required for your
configuration.
