Configuring RADIUS

RADIUS RADIUS is Remote Authentication Dial-in User Service. The Radius Server is the AAA service provider. AAA stands for Authentication, Authorization, and Accounting. The RADIUS Client is the network access server or device (i.e. wireless router.) RADIUS is scalable and interoperable. RADIUS and TACACS+ are the most common AAA servers. RADIUS uses UDP ports 1812 for authentication and 1813 for accounting. TACACS+ uses TCP port 49. Kerberos uses TCP port 88 and UDP port 88. LDAP uses TCP port 389, while LDAP over SSL uses TCP port 636.

A system administrator is using a packet sniffer to troubleshoot remote authentication. The sniffer detects a device trying to communicate on UDP ports 1812 and 1813. Which of the following authentication methods is being attempted? Kerberos LDAP RADIUS TACACS+

LEAP Cisco's Lightweight Extensible Authentication Protocol (LEAP) is an older implementation of Extensible Authentication Protocol (EAP) that uses Temporal Key Integrity Protocol (TKIP) and dynamic Wired Equivalency Protocol (WEP) keys to secure wireless authentication to a remote RADIUS server. The newer Protected Extensible Authentication Protocol (PEAP) used Public Key Infrastructure (PKI) and Transport Layer Security (TLS) for authentication confidentiality. PEAP has largely replaced LEAP.

The security administrator for Corp.com has been directed by the CIO to implement a secure wireless authentication method that uses a remote RADIUS server for authentication. Which of the following authentication methods should be used? PAP LEAP MS-CHAP CHAP

D. Distributed Security

What is the core principle behind RADIUS? A. Distributed challenge and response B. Ticket granting ticket C. Centralized security D. Distributed security

EAP

What protocol offers the capability to deploy RADIUS in an Ethernet network? CHAP V2 CHAP V3 MSCHAP PAP EAP

RADIUS RADIUS is a security protocol for controlling remote access. It is both an access server and also a system of distributed security that secures remote access against improper attempts. A RADIUS server should be placed inside the general network's secure subnet.

Which of the following are both an access server and also a system of distributed security that secures remote access against improper attempts? RRAS SSH TELNET RADIUS NAC+
