Security Fundamentals

What is a characteristic of encryption in wireless networks?

  • A used to ensure data integrity
  • B uses 802.1x as the standard encoding method
  • C uses protocols such as TKIP and CCMP to secure data
  • D only works with the 5Ghz frequency
Explanation

Wireless network encryption secures data in transit by using Wi‑Fi security protocols and ciphers such as TKIP in older WPA deployments and CCMP in WPA2/WPA3. 802.1X is used for port-based authentication rather than as an encryption method, and wireless encryption is not restricted to the 5 GHz band.
