  1. yup it’s A

    Recognizing the popularity of wireless devices in non-enterprise networks, the Wi-Fi
    Alliance introduced Wi-Fi Protected Setup (WPS) in 2006. The goal of WPS is to enable
    anyone to join a WPS-capable device to a WPS-enabled wireless network just by pressing
    two buttons. Press the button on the WAP (Figure 7-4), then press the button on the
    device you want to join to the network; your device connects to the SSID and takes on
    the WAP’s WPA2 encryption. Neat!
    Alternatively, every WPS-enabled WAP comes with a fixed eight-digit pin code to
    allow devices without a WPS button (like a laptop) to connect to the WAP. You pressed
    the button on the router and then entered the router’s pin code as the SSID’s password.
    Unfortunately, the eight-digit code has two problems. First, only seven of the eight
    digits are used (the eighth digit was only a checksum). Additionally, the seven digits are
    confirmed in two groups: the first three values, then the last four. This means it only
    takes about 11,000 guesses to crack a WPA pin code. Yipe!

      I think anyone taking the test should know better than to ever use WPS. I hope that’s not the right answer.

      The users of this network are employees, so should have a username/password already. So why not use a Radius server and 802.1x as in answer B? The only reason I can see to not do this is because it is mentioned that this is in a “small office” which may not have the resources.
