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 |
TACACS+ and RADIUS are the correct answers. |
|
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. |
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. |
– 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+ |

RADIUS is primarily used for what purpose?
– Managing access to a network over a VPN. – Managing RAID fault-tolerant drive configurations. – Controlling entry gate access using proximity sensors. – Authenticating remote clients before access to the network is granted. |
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. |
