A user has been accessing files onserver on your network and now wants to connect to a Web server that is used as part ofthe company’s intranet.The user enters the URL of the Web site into Internet Explorer.Which of the following servers will be used to provide information needed to connect tothe Web server?A. DHCP serverB. DNS serverC. WINS serverD. File serverB. DNS servers map fully qualified domain names (like https://traloihay.net) to IPaddresses.When a user enters a DNS name into a Web browser or other application, itis sent to a DNS server, which looks up the IP address for the requested name.This IPaddress is sent back to the client, which uses it to locate and communicate with theserver.A, C, D. Answer A is incorrect because DHCP servers are used to issue IP addressesto clients. Because TCP/IP is the only protocol used on the network, and the useralready has been accessing resources on a file server, this means that the user already hasan IP address. Answer C is incorrect because a URL has been entered and WINSservers are used to resolve NetBIOS names to IP addresses (and vice versa). Answer D isincorrect because servers configured in the role of a file server would not need to pro-vide any information to clients accessing an intranet Web site.
