- TACACS+ - RADIUS

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.

Encrypts the entire packet, not just authentication packets.

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.

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.

You are configuring your computer to dial up to the internet. What protocol should you use? - PPTP - PPP - SMTP - VPN

PPP

Which of the following protocols or services is commonly used on cable internet connections for user authentication? - PPPoE - PPP - RDP - RRAS

PPPoE

You have just signed up for internet access using a local provider that gives you a fiber optic line into your house. From there, Ethernet and wireless connections are used to create a small network within your home. Which of the following protocols would be sued to provide authentication, authorization, and accounting for the internet connection? - PPP - L2TP - ICA - PPPoE - RDP

PPPoE

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