Which of the following encryption techniques will BEST protect a wireless network from a man-in-the-middle attack?

A. 128-bit wired equivalent privacy (WEP)
B. MAC-based pre-shared key(PSK)
C. Randomly generated pre-shared key (PSKJ
D. Alphanumeric service set identifier (SSID)

Correct Answer: C

Explanation:

Explanation:
A randomly generated PSK is stronger than a MAC-based PSK, because the MAC address of a computer is fixed and often accessible. WEP has been shown to be a very weak encryption technique and can be cracked within minutes. The SSID is broadcast on the wireless network in plaintext.
