300-430 Question 189
Single answerA company is implementing wireless security for its internal Wi-Fi network. The security policy requires strong authentication, encryption, and the ability to integrate with the existing RADIUS server for user identity verification. Which wireless security protocol should they configure on their wireless LAN controller (WLC) to meet these requirements?
- A
WEP (Wired Equivalent Privacy)
- B
WPA2-PSK (Wi-Fi Protected Access 2 - Pre-Shared Key)
- C
WPA2-Enterprise
- D
Open Authentication
Show answer and explanation
Correct answer: C
Explanation
WPA2-Enterprise is the most appropriate choice for enterprise wireless networks requiring strong authentication, encryption, and integration with a RADIUS server. It uses 802.1X/EAP for authentication and provides robust encryption with AES, ensuring compliance with the company's security policy. The other options either lack sufficient security or do not support RADIUS integration.
- A. Incorrect.
WEP is outdated and insecure, as it uses weak encryption algorithms and can be easily compromised. It does not meet the requirement for strong authentication or encryption.
- B. Incorrect.
WPA2-PSK uses a pre-shared key for authentication, which does not integrate with a RADIUS server for user identity verification. It is suitable for smaller networks but not for enterprise environments requiring robust security.
- C. Correct.
WPA2-Enterprise is designed for enterprise environments. It supports strong encryption (AES), uses 802.1X/EAP for authentication, and integrates with a RADIUS server for user identity verification, meeting all the stated requirements.
- D. Incorrect.
Open Authentication provides no security at all, as it does not require any authentication or encryption. This does not meet the security requirements for the company's internal Wi-Fi network.
