Which of the following are methods for providing centralized authentication, authorization, and accounting for remote access? (Select two.)


– TACACS+


– 802.1x


– AAA


– PKI


– RADIUS


– EAP


Answer: TACACS+ and RADIUS


You have decided to implement a remote access solution that uses multiple remote access servers. You want to implement RADIUS to centralize remote access authentication and authorization.


 


Which of the following is a required part of your configuration?


 


– Configure the remote access severs as RADIUS servers.


– Configure remote access clients as RADIUS clients.


– Configure the remote access servers as RADIUS clients.


– Obtain certificates from a public or private PKI.


Answer: Configure the remote access servers as RADIUS clients.







Which of the following are characteristics of TACACS+? (Select two.)


– Allows the possibility of two different servers, one for authentication and authorization, and another for accounting.


– Allows the possibility of three different servers, one for each authentication, authorization, and accounting.


– Uses TCP.


– Uses UDP.


Answer: – Allows the possibility of three different servers, one for each authentication, authorization, and accounting.

– Uses TCP.



Which of the following are difference between RADIUS and TACACS+?


 – RADIUS combines authenticaiton and authorization into a single function; TACACS+ allows these services to be split between different servers.


– RADIUS uses TCP; TACACS+ uses UDP.


– RADIUS encrypts the entire packet contents; TACACS+ only encrypts the password.


– RADIUS supports more protocols than TACACS+


Answer: RADIUS combines authenticaiton and authorization into a single function; TACACS+ allows these services to be split between different servers.


Which of the following protocols can be used to centralize remote access authentication?


– EAP


– SESAME


– TACACS


– CHAP


– Kerberos


Answer: TACACS


RADIUS is primarily used for what purpose?


– Managing access to a network over a VPN.


– Managing RAID fault-tolerant drive configurations.

Answer: Authenticating remote clients before access to the network is granted.



Which of the following is a characteristic of TACACS+?


– Requires that authentication and authorization are combined in a single server.


– Encrypts the entire packet, not just authentication packets.


– Uses UDP ports 1812 and 1813.


– Supports only TCP/IP.


Answer: Encrypts the entire packet, not just authentication packets.



Which of the following ports are used with TACACS?


– 22


– 49


– 50 and 51


– 1812 and 1813


– 3389


Answer: 49
