Mark works as a Network Administrator for Infonet Inc. The company has a Windows 2000 Active Directory domain-based network. The domain contains one hundred Windows XP Professional client computers. Mark is deploying an 802.11 wireless LAN on the network. The wireless LAN will use Wired Equivalent Privacy (WEP) for all the connections. According to the company's security policy, the client computers must be able to automatically connect to the wireless LAN. However, the unauthorized computers must not be allowed to connect to the wireless LAN and view the wireless network. Mark wants to configure all the wireless access points and client computers to act in accordance with the company's security policy. What will he do to accomplish this? Each correct answer represents a part of the solution. (Choose three.)

Answers
F.

Suggested answer: B, C, F

Explanation:

To configure all the wireless access points and client computers to act in accordance with the company's security policy, Mark will take the following actions:

Configure the authentication type for the wireless LAN to Shared Key. Shared Key authentication provides access control. Disable SSID Broadcast and enable MAC address filtering on all the wireless access points. Disabling SSID Broadcast and enabling MAC address filtering will prevent unauthorized wireless client computers from connecting to the access point (AP). Only the computers with particular MAC addresses will be able to connect to the wireless access points. On each client computer, add the SSID for the wireless LAN as the preferred network.

Answer option E is incorrect. Setting the authentication type for the wireless LAN to Open System will disable Wired Equivalent Privacy (WEP). This level of WEP will not provide security.
