The ARPANET(66)( the rules of syntax that enable computers to communicate on a network)were originally designed for openness and flexibility, not for(67)The ARPA researchers needed to share information easily, so everyone needed to be an unrestricted "insider" on the network. Although the approach was appropriate at the time, it is not one that lends itself to today's commercial and government use.As more locations with computers(known as(68)in Internet parlance)joined the ARPANET, the usefulness of the network grew. The ARPANET consisted primarily of university and government computers, and the applications supported on this network were simple: electronic mail( E - mail), electronic news groups, and(69)connection to other computers. By 1971, the Internet linked about two dozen research and government sites, and researchers had begun to use it to exchange(70)not directly related to the ARPANET itself.

You install a new hardware router that provides wireless network connectivity between your computer and the Internet. You connect to the router by using a wireless network adapter. Your computer is able to access the Internet but is unable to discover other computers in the local wireless network. You need to configure the wireless connection to allow your computer to discover other computers. What should you do？（）A、Configure the network category of your wireless network connection to Private.B、Configure the network category of your wireless network connection to Public.C、Configure the TCP/IP packet filtering on the wireless network connection.D、Configure the wireless network connection with the appropriate authentication to the router.
You are a network adminstrator for your company. You install an intranet application on three Windows Server 2003 computers. You configure the servers as a Network Load Balancing cluster. You configure each server with two network adapters. One network adapter provides client computers access to the servers. The second network adapter is for cluster communications. Cluster communications is on a separate network segment. The network team wants to reduce the cluster’s vulnerability to attack. These servers need to be highly available. The network team decides that the Network Load Balancing cluster needs to filter IP ports. The team wants the cluster to allow only the ports that are required for the intranet application. You need to implement filtering so that only the intranet application ports are available on the cluster. You need to achieve this goal by using the minimum amount of administrative effort. What should you do？ （）A、 Use Network Load Balancing Manager to configure port rules. Allow only the intranet application ports on the cluster IP address.B、 Use TCP/IP filtering on each server. Configure only the intranet application ports on the network adapter that provides client computers access to the servers.C、 Use TCP/IP filtering on each server. Configure only the intranet application ports on both of the network adapters.D、 Configure Routing and Remote Access on each server. Use Routing and Remote Access input filters to allow only the intranet application ports on the network adapter that provides client computers access to the servers.
