QUESTION

When connecting to an 802.11 Wireless access point, which mode should be used?

A. WEP (Wired Equivalent Privacy)

B. Infrastructure

C. Ad-hoc

D. Remote

Answer: A

WEP(Wired Equivalent Privacy) is a security protocol for wireless local area networks (WLANs) defined in the 802.11b standard. 

WEP is designed to provide the same level of security as that of a wired LAN. LANs are inherently more secure than WLANs because LANs are somewhat protected by the physicalities of their structure, having some or all part of the network inside a building that can be protected from unauthorized access. 

WLANs, which are over radio waves, do not have the same physical structure and therefore are more vulnerable to tampering. 

WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one endpoint to another. 

However, it has been found that WEP is not as secure as once believed. WEP is used at the two lowest layers of the OSI model - the data link and physical.
