Demo Question 3.

You are a senior network administrator for EliteCertify.com. EliteCertify consists of a main office and a branch office. Internet access at the branch office is through a cable modem and access to main office servers uses a virtual private network (VPN) connection. The cable modem is connected to a Windows XP Professional computer named EliteCertify 1. EliteCertify 1 has Internet Connections Sharing (ICS) configured to allow users in the branch office to use the VPN connection. ICS sets the internal network adapater to use the IP address 192.168.0.1. Several sales representatives in the branch office use wireless network adapters to share files between their client computers. They need access to the VPN connection to upload sales reports to the main office. You install a wireless network adapter in EliteCertify 1 and configure it with the appropriate settings for the wireless LAN. The sales representatives who use the wireless LAN report that they cannot access the VPN connection. However, they are able to connect to resources in the branch office. Users on the wired network do not report any connectivity problems. The sales representatives need to be able to access the VPN. What should you do?

B. Disable and re-enable Internet Connection Sharing (ICS) on EliteCertify 1.

Answer: C

Explanation: You can create a Network Bridge connecting two or more local area networks and share the Internet connection with the computers on all of them. This is especially useful if your XP computer is connected to both a wired and wireless network. Note: The Network Bridge feature of ICS was introduced with Windows XP. It is not available in earlier versions of Windows. Incorrect
