Wep-shared-both wep-open and wep-shared are forms of wireless security. wep-open is the simpler of the two authentication methods because it does not perform any type of client verification. it is a very weak form of authentication because it requires no proof of identity. wep-shared requires that a wep key be configured on both the client system and the access point. this makes authentication with wep-shared mandatory and therefore more secure for wireless transmission. answers b and d are not valid wep options.
