A network administrator is securing a new wireless network and selects WPA2 for its broad compatibility and strong security. Which encryption standard is a mandatory component of WPA2, providing robust protection for wireless communications?
Utilizes AES for securing communications over wireless networks.
Designed specifically for government applications but is also used in consumer contexts.
Employs TKIP as its primary encryption method.
Uses encryption protocols that are less effective than those in more recent standards.
The correct answer identifies that WPA2 uses the Advanced Encryption Standard (AES) for robust security. WPA2 mandates the use of Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP), an encryption protocol based on AES.
The option mentioning Temporal Key Integrity Protocol (TKIP) is incorrect. TKIP is an older, less secure protocol associated with the original WPA standard and is considered deprecated.
While it is true that WPA2 is less secure than the newer WPA3 standard, this statement is a comparison and not a description of a core feature or component of WPA2.
The claim that it was designed for government applications is not accurate; while AES was adopted by the U.S. government, WPA2 itself was developed by the Wi-Fi Alliance for broad commercial and private use.
