There have been concerns in your network that the wireless network component is not sufficiently secure. You perform a vulnerability scan of the wireless network and find that it is using an old encry

WEP (Wired Equivalent Privacy) is actually the protocol whose name and design goal explicitly mirror wired network security - this choice directly matches the question description, strongly suggesting A is the intended correct answer and the provided key contains an error.

RADIUS (Remote Authentication Dial-In User Service) is an authentication, authorization, and accounting protocol used for network access control, not a wireless data encryption protocol.

WPA (Wi-Fi Protected Access) is an older wireless security protocol that introduced TKIP to improve upon WEP weaknesses. However, the question description 'designed to mimic wired encryption' is the literal meaning of WEP (Wired Equivalent Privacy), so the intended correct answer is most likely A (WEP), and C appears to be a mistake in the answer key.

WPA3 is the latest and most secure Wi-Fi security standard, introduced in 2018; it is not an old protocol, and it was not designed to mimic wired encryption.
