Which of the following is mainly used for remote access into the network?
A. XTACACS B. TACACS+ C. Kerberos D. RADIUS
Correct Answer: D Section: Access Control and Identity Management
Most gateways that control access to the network have a RADIUS client component that communicates with the RADIUS server. Therefore, it can be inferred that RADIUS is primarily
used for remote access.
A: XTACACS has been replaced by RADIUS and TACACS+.
B: The separate components of the TACACS+ protocol is segregated and handled on different servers, whereas the RADIUS protocol is centralized. This means that not only
TACACS+ is used by the TACACS+ protocol for remote access.
C: Kerberos is primarily used for the protection for logon credentials.
