What is the encryption method for the Guest WLAN?

• A. None
• B. WEP
• C. WPA2
• D. WPA

Answer: (C)

Protecting a guest WLAN requires a strong, modern encryption method. None would leave traffic unprotected, and WEP is outdated and easily cracked due to weak initialization vectors and vulnerabilities in RC4. WPA adds security over WEP but uses TKIP, which is no longer considered secure. WPA2, on the other hand, uses AES-based CCMP encryption, providing robust confidentiality and integrity for wireless traffic. Among these options, WPA2 is the best choice for a guest network, offering the strongest protection with current standards.
