CompTIA Security+ (SY0-501) — Question 52

A security administrator has configured a RADIUS and a TACACS+ server on the company's network. Network devices will be required to connect to the TACACS
+ server for authentication and send accounting information to the RADIUS server. Given the following information:

RADIUS IP: 192.168.20.45 -

TACACS+ IP: 10.23.65.7 -
Which of the following should be configured on the network clients? (Choose two.)

Answer options

• A. Accounting port: TCP 389
• B. Accounting port: UDP 1812
• C. Accounting port: UDP 1813
• D. Authentication port: TCP 49
• E. Authentication port: TCP 88
• F. Authentication port: UDP 636

Correct answer: C, D

Explanation

The correct answers are C and D. C is correct because RADIUS uses UDP 1813 for accounting, while D is accurate since TACACS+ relies on TCP 49 for authentication. The other options do not correspond to the correct protocols and ports for RADIUS and TACACS+ services.
