Which Wi-Fi security protocol is commonly used for home networks?

• A. WEP
• B. WPA2-PSK
• C. TKIP
• D. WPA3-Enterprise

Answer: (B)

When setting up a home Wi‑Fi network, you want a security method that is both easy to use and provides solid protection. WPA2-PSK achieves this by using AES-based encryption (CCMP), which strongly protects data moving over your wireless link. It relies on a single pre-shared key (a passphrase) that’s simple to configure for everyone in the home, and it’s widely supported by most devices, making it the practical default for most households. WEP is outdated because its encryption can be cracked with modern tools. TKIP is an older, transitional protocol that doesn’t offer the strongest safeguards today. WPA3-Enterprise is aimed at business environments with centralized authentication and isn’t the typical setup for home networks. For these reasons, WPA2-PSK is the common choice for home networks. If available, you can upgrade to WPA3-Personal in newer devices for even better security, but WPA2-PSK remains the standard in most homes.
