Which statement about wireless security protocols is true?

• A. WEP is stronger than WPA
• B. WPA and WPA2 are older than WEP
• C. WEP is never crackable
• D. WPA is the successor to WEP

Answer: (D)

Understanding how wireless security protocols evolved helps explain why that statement is true. WEP was the original Wi‑Fi security method, but it has serious flaws in how it handles keys and initialization vectors, making it susceptible to cracking and impersonation. To fix these issues without requiring new hardware for many devices, WPA was introduced as an upgrade; it uses improved encryption with TKIP, per-packet keys, and better integrity checks, effectively serving as a successor to WEP. Later, WPA2 came along with even stronger security based on AES. So the statement that WPA is the successor to WEP is the best one. The other options misstate the history or the security realities: WEP isn’t stronger than WPA, WEP has known vulnerabilities and is crackable, and WPA/WPA2 aren’t older than WEP.
