You are configuring a TACACS+ server and the security team asks you for details about this protocol.
Which three statements about the TACACS+ protocol are true? (Choose three.)
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
TACACS+ (Terminal Access Controller Access-Control System Plus) is a network protocol that provides centralized authentication, authorization, and accounting (AAA) management for devices in a network. It is commonly used in enterprise environments to authenticate and authorize access to network devices, such as routers, switches, and firewalls.
To answer the question, we need to determine which three statements about the TACACS+ protocol are true:
A. It is TCP based. True. TACACS+ uses TCP as its transport protocol. This ensures reliable delivery of authentication, authorization, and accounting messages between the client and the TACACS+ server.
B. It is UDP based. False. TACACS+ does not use UDP as its transport protocol.
C. It uses port 49 by default. True. TACACS+ uses port 49 as its default port number for communication between the client and the TACACS+ server.
D. It uses port 59 by default. False. TACACS+ does not use port 59 as its default port number.
E. The username is sent in cleartext. False. TACACS+ encrypts the username and password using a one-way hash algorithm before transmitting them over the network. This ensures that sensitive user information is not transmitted in clear text and cannot be intercepted and read by unauthorized users.
F. The username is encrypted. True. As mentioned above, TACACS+ encrypts the username and password using a one-way hash algorithm before transmitting them over the network.
Therefore, the correct answers are A, C, and F.
