Due to hardware limitation, a technician must implement a wireless encryption algorithm that uses the RC4 protocol. Which of the following is a wireless encryption solution that the technician should

The correct answer is C. WPA-TKIP. The key constraint is that the hardware only supports RC4-based encryption. This eliminates WPA2-AES (option A), which uses AES/CCMP - not RC4 - and is generally the strongest option but unavailable here. Option B (802.11ac) is a wireless networking standard, not an encryption al

Explanation

The key constraint is that the hardware only supports RC4-based encryption. This eliminates WPA2-AES (option A), which uses AES/CCMP - not RC4 - and is generally the strongest option but unavailable here. Option B (802.11ac) is a wireless networking standard, not an encryption algorithm, so it is not applicable. That leaves WEP (D) and WPA-TKIP (C), both of which use RC4. WEP uses RC4 with a static key and a weak 24-bit initialization vector (IV), making it highly vulnerable. WPA-TKIP (Temporal Key Integrity Protocol) also uses RC4 but adds significant security improvements: per-packet key mixing, a message integrity check (MIC), and a longer IV. Among the RC4-based options available, WPA-TKIP provides the strongest security.
