What is a characteristic of encryption in wireless networks?
The correct answer is C. uses protocols such as TKIP and CCMP to secure data. Encryption in wireless networks uses specific protocols to secure data confidentiality and integrity during transmission over the air.

Why each option
Encryption in wireless networks uses specific protocols to secure data confidentiality and integrity during transmission over the air.
While encryption provides confidentiality, data integrity is specifically ensured by integrity checks (like MIC in TKIP or the MAC part of CCMP), which are often part of the encryption suite but distinct from the encryption function itself.
802.1X is an authentication framework that controls port access based on credentials, not an encoding or encryption method for wireless data.
Wireless network encryption relies on protocols like TKIP (Temporal Key Integrity Protocol) used in WPA, and CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) used in WPA2/WPA3, to provide robust security for data in transit.
Wireless encryption protocols are designed to work across all common Wi-Fi frequencies, including 2.4 GHz, 5 GHz, and 6 GHz (for Wi-Fi 6E), not exclusively 5 GHz.
