100-160 Question 31
Single answerA company is implementing a new wireless network and wants to ensure secure user authentication while maintaining centralized control over access permissions. They decide to use a protocol that supports Authentication, Authorization, and Accounting (AAA). Which protocol would best meet their needs?
- A
RADIUS
- B
LDAP
- C
SNMP
- D
HTTPS
Show answer and explanation
Correct answer: A
Explanation
RADIUS is the appropriate protocol for implementing Authentication, Authorization, and Accounting (AAA) in a centralized manner. It is widely used in wireless networks to securely authenticate users and enforce access permissions. The other options, while useful in specific contexts, do not provide the comprehensive AAA functionality required for this scenario.
- A. Correct.
RADIUS (Remote Authentication Dial-In User Service) is a protocol specifically designed for AAA functionality. It centralizes authentication, authorization, and accounting services, making it ideal for managing secure wireless networks.
- B. Incorrect.
LDAP (Lightweight Directory Access Protocol) is a protocol used for querying and modifying directory services, but it is not designed for comprehensive AAA functionality.
- C. Incorrect.
SNMP (Simple Network Management Protocol) is used for monitoring and managing network devices, not for authentication, authorization, or accounting.
- D. Incorrect.
HTTPS (Hypertext Transfer Protocol Secure) is used for secure web communication but is not related to AAA services.
