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?

– SESAME

– TACACS

– CHAP

– Kerberos

Answer: TACACS

RADIUS is primarily used for what purpose?

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.

– 22

– 49

– 50 and 51

– 1812 and 1813

– 3389
