Does anyone know the correct answer to this question?

My guess is D.  

Please correct me if I'm wrong thanks.

6)  The company has a main office and a branch office. The branch office has a wireless network. The Service Set Identifier (SSID) of the wireless network is named CoBranch. Data on the wireless network is protected by using static Wired Equivalent Privacy (WEP) keys.

A user travels from the main office to the branch office. The user's portable computer has a wireless network adapter that supports the Wireless Zero Configuration service. The wireless network connection icon in the taskbar notification area indicates that the wireless adapter is connected to CoBranch with a signal strength of Excellent.

The user reports that she is unable to access her e-mail messages or connect to any Web sites on the Internet. You discover that the IP address displayed in the Wireless Network Connection Status dialog box is 169.254.66.227.

You verify that the branch office DHCP server is running and configured correctly and that other branch office users are able to connect to the wireless network, access their e-mail messages, and view Web sites on the Internet.

You need to ensure that the user is able to access her e-mail and connect to Web sites on the Internet. What should you instruct the user to do?

A. Clear the Enable network access control using IEEE 802.1x check box on the Authentication tab of the Wireless Network Connection properties page.

B. Select the Data encryption (WEP enabled) check box on the WireLess Networks Properties tab of the Wireless Network Connection properties page.

C. Select the Network Authentication (Shared mode) check box on the Wireless Networks Properties tab of the Wireless Network Connection properties page.

D. Enter the SSID of the branch office wireless network on the Wireless Networks Properties tab of the Wireless Network Connection properties page.

Without the proper WEP key set, the client wont be able to send a DHCP request, and will not receive an IP address, or anything else for that matter.  The problem states that the client has locked on to the CoBranch signal, so the only think left to do is enter the WEP key.

A is correct.

The Wireless Zero Configuration service allows you to configure multiple wireless network configurations on a wireless NIC. If you relocate your laptop, it automatically scans its list of wireless networks it has configured. When it finds one, it will let you know which one it found. i.e. CoBranch.
This means the CoBranch wireless network settings are already preconfigured.
The one area that would keep it from actually connecting to a DHCP server to get an IP address is if it had the Enable network access control using IEEE 802.1x check box selected. This is a type of authentication, and since the scenario didn't mention anything about this being set up on the network, we should not assume it was.
