What security solution is deprecated in the 802.11 standard and should never be used in any modern WLAN deployment?
The security solution deprecated in the 802.11 standard and should never be used in any modern WLAN deployment is Shared Key Authentication. This method is considered insecure because it can be easily compromised and thus should be avoided in favor of more secure authentication methods such as WPA2 or WPA3, which use more robust encryption techniques like CCMP (Counter Mode Cipher Block Chaining Message Authentication Code Protocol) and AES (Advanced Encryption Standard).
A is correct for me : "Although Shared Key authentication might seem to be a more secure solution than Open System Authentication, in reality Shared Key could be the bigger security risk". You can refer to p.731 of Study Guide (6th Edition) for the full quote.
'802.11 authentication is either Open System Authentication or Shared Key Authentication. Shared Key Authentication is deprecated in the standard and is not secure. It should never be used today. Open System Authentication is performed before either Pre-Shared Key or 802.1X/EAP authentication.' Official Book CH 7
I would say B Open system Authentication
