Which security mode is commonly used with Wi-Fi networks to permit password-protected access?

• A. WEP
• B. WPA2-PSK
• C. SSH
• D. TLS

Answer: (B)

Wi-Fi network access is controlled by how the network requires proof of authorization. The option that uses a shared password to grant access is WPA2-PSK (WPA2-Personal). It provides password-based protection for joining the network and encrypts traffic once connected, which is why it’s the standard choice for home and small-office networks. WEP is outdated and insecure due to weak encryption and easily cracked keys. SSH and TLS are protocols for securing individual connections (remote login and web traffic), not for controlling access to the wireless network itself. So, WPA2-PSK is the commonly used mode for password-protected Wi‑Fi access.
