Contoso, Ltd. s company policy mandates that only e-mail and Hypertext Transport Protocol (HTTP) traffic can pass in or out of its intranet. As a result, only inbound and outbound TCP port 25 and TCP port 80 traffic is permitted. Contoso s employees fre quently access the Web site of the company s main supplier at http://www.north windtraders.com to download product information. Northwind Traders announces that its site is going down over a weekend so that it can implement improvements. When Contoso employees access the site on the following Monday they get the message, Web page requested is not available. You are Con toso s network manager. You note that https:// appears in the address bar. You confirm that the site is up and running by accessing it from your home computer. What action should you take

A. Allow traffic on TCP port 443. B. Allow traffic on TCP port 53. C. Configure the default IPSec Client (Respond Only) policy on the client computers. D. An authentication problem exists. You need to get passwords from Northwind

Maintaining a Network Infrastructure (5.0)

A. Incorrect: The ISP is dialed on demand, not Mag1. B. Incorrect: The public address pool consists of the public address provided by

A. Incorrect: The LAN uses private addresses, not public addresses. B. Incorrect: Whether they get their addresses from DHCP or from the NAT DHCP

C. Correct: The most probable fault is that a subnet mask of 255.255.255.254 is con-

figured on the public interface. The configuration in answer C ensures that all eight public addresses are used.

D. Incorrect: Special ports allow external users to access resources on a private net-

work through the Internet. Typically, a special port allocates a public address to the private address of a Web server that hosts the company s Web site. This setup is not needed in this scenario.

tion problem when https:// appears on the address bar. Web page encryption is implemented using the Secure Sockets Layer (SSL) protocol. This protocol uses TCP port 443. Northwind s improvements probably include onsite ordering or other facilities that require a secure site.

Contoso has a DNS server that needs to receive zone information from an external source. DNS is not the problem. Clients are resolving http://www.northwind traders.com to an IP address otherwise, they would not be getting the message stated.

toso employees are connected to Northwind s Web server, although they cannot obtain the Web page. Internet Protocol Security (IPSec) is not the problem. In any case, IPSec is used to encrypt data through VPN tunnels, not to encrypt Web sites.

This objective requires you to know how to manage and troubleshoot the services that run on servers and clients running Windows Server 2003. The principle of least priv ilege mandates that you use the Services snap-in from your client machine to perform these functions because you should be logged on using your ordinary user account, and ordinary users cannot (typically) log on locally to a server. You need to know how to do this. You need to know about service dependencies, and what would happen if a core service failed on which many other services depend. You need to know how to configure services to automatically recover after a failure. You need to know how to configure services to start automatically or manually, and how to disable a service. You need to know how to interpret messages in Event Viewer that indicate service failure.
