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.
– Controlling entry gate access using proximity sensors.
– Authenticating remote clients before access to the network is granted.
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
