Which statement about the TACACS+ AV pair is true?
Click on the arrows to vote for the correct answerA. B. C. D.
TACACS+ is a protocol that is commonly used for authentication, authorization, and accounting (AAA) services in computer networks. The protocol uses AV pairs to exchange information between a client and a server during the authentication and authorization processes.
An AV pair (Attribute Value pair) is a method used by TACACS+ to convey additional attributes between the TACACS+ client and server. The attribute is represented by an ASCII string and is followed by its corresponding value, which could be either a string or an integer. The combination of the attribute and its value is referred to as an AV pair.
Now, let's examine each answer choice in detail:
A. AV pair value is an integer.
This statement is incorrect. The value of an AV pair can be either a string or an integer.
B. Cisco ACS does not support accounting AV pairs.
This statement is incorrect. Cisco ACS (Access Control Server) does support accounting AV pairs. TACACS+ can use accounting AV pairs to provide additional accounting information to the TACACS+ server.
C. AV pair values could be both strings and integers.
This statement is correct. The value of an AV pair can be either a string or an integer. This flexibility allows TACACS+ to support a wide range of attributes.
D. AV pair does not have a value type.
This statement is incorrect. The value of an AV pair can be either a string or an integer. Therefore, it has a value type.
In conclusion, the correct answer is C: AV pair values could be both strings and integers.
