Understanding Windows 2003 Server Network Protocols

1.	You are implementing a network that will include UNIX workstations that will share files and information with the Windows users. What protocols will you need to implement to provide integration with UNIX machines? IPX/SPX NetBEUI TCP/IP NetBIOS over TCP/IP
2.	You purchased a new desktop computer running Windows XP for your small office and a server running Windows Server 2003. Your old desktop is running Windows 95. It has a network adapter and can access files on another Windows 95 machine. The Windows XP machine has not arrived, but you want to back up the data from the Windows 95 computer to the Windows Server 2003 machine. However, from the Windows Server 2003 computer, you are unable to see the shares on the Windows 95 computer. What should you do to allow the Windows Server 2003 machine to access the Windows 95 machine? Install NetBEUI on Windows Server 2003 computer. Install NWLink on the Windows 95 client. Install TCP/IP on the Windows 95 client. Ensure the server has a valid IP address and implement a DHCP server on the Windows Server 2003 machine with a valid scope.

Planning an IP Addressing Strategy

3.	You are implementing a test lab that contains three Windows Server 2003 machines, twenty Windows XP Professional machines, and two IP-based printers. You have been given the network address of 155.1.50.0 and a subnet mask of 255.255.255.224. What is the CIDR notation for your subnet? 155.1.50.0/27 155.1.50.0/5 155.1.50.0/24 155.1.50.0/3
4.	You are given a task to create eight subnets on your LAN, and you have been assigned the address space 172.16.128.0/23. How many hosts will you have and what is the CIDR notation for the new subnet’s address space? 2032 hosts on 172.16.128.0/24 240 hosts on 172.16.128.0/27 496 hosts on 172.16.128.0/26 48 hosts on 172.16.128.0/29
5.	Which of the following addresses is suitable for dividing into at least nine subnets, each with the ability to support 200 hosts per network? 10.1.1.0/24 10.1.1.0/20 10.1.1.0/19 10.1.1.0/22
6.	You are having trouble accessing Microsoft’s Web site. When you ping www.microsoft.com, the request times out. How should you proceed in troubleshooting this problem? Ping the loopback adapter, the IP address of this machine, then the default gateway and determine if your connectivity is valid. If there are no issues, run tracert and identify where the communications stop. Ping the default gateway, the IP address of a remote host other than Microsoft, such as Yahoo, then ping the IP address of this machine and then the loopback adapter. Use Network Monitor to analyze the traffic to www.microsoft.com. Use System Monitor to look at counters on the local machine to determine the error.
7.	You implement a Windows Server 2003 machine that is functioning as a file server on your LAN. The server name is FileServer01. Users attempting to browse the shares on \\FileServer01\ are unable to see any of the shares you created. What is likely the problem? You do not have DNS installed on the LAN. DCHP is unavailable. NetBIOS encapsulation is not enabled on the Windows Server 2003 machine. FileServer01 FTP service is stopped.
8.	A client computer configured as a DCHP client was unable to obtain an address from the DCHP server. Upon investigation, you discovered that the DCHP scope was not activated, so you activated it. The client computer has an APIPA address of 169.254.0.1. What actions are required for the client to obtain an IP address from the DHCP server? Run ipconfig /all from a command prompt. Use Netsh to assign an address to the network adapter. Log off Windows XP and log on again. Take no action.

Planning the Network Topology

9.	Your company is merging with another organization, and you have been tasked with merging the corporate networks. You have determined that the other company has between 50 and 125 hosts on 7 networks. Your company has 25 to 50 hosts on 12 networks. You want the integration to provide room for five percent growth over the next two years. Your routers do not support variable-length subnet masks. You decide to use the private address 192.168.0.0. What is the best subnet mask for your new corporate LAN? 255.255.0.0 255.255.255.0 255.255.255.192 255.255.224.0
10.	You want to simplify the configuration and management of TCP/IP clients on your network, which consists of 300 Windows XP Professional machines, 12 Windows Server 2003 machines, and 23 printers on four subnets. Which of the following solutions best suits your needs? Implement WINS using APIPA. Provide at least one DNS server for each WINS server. Implement DHCP to provide assigned IP address leases and scope properties that contain the necessary host resolution methods, the IP address of the default gateway, and the DNS servers. Implement AD integrated DNS and WINS and configure WINS to do reverse lookups. Provide thorough documentation for each client to manually configure its IP address with a valid subnet mask and DNS server.
11.	All of the clients on your network are configured to use DHCP for their TCP/IP configuration. You upgrade Internet access to use a T1 line that is connected to a different router than the current router that is being used by the Digital Subscriber Line (DSL) connection. What actions are required to allow the executive staff to access the Internet using the new default gateway, by configuring each executive’s machine only one time, while not allowing the other company employees to use the T1? Create a logon script for the Executives Group that uses the route add –d command to add the new router information. Set the script to run every time members of the Executive Group log on. Create a logon script for the Executives Group that uses the route add –p command to add the new router information. Set the script to run once the next time members of the Executive Group log on. Create a new property for the router in the DCHP scope options. Set up reservations for each of the executive’s machines. Run the command route add with the information for the new router on each executive’s machine.
12.	You have integrated a smaller LAN into your network that contains a Novell NetWare server using IPX/SPX. You want to be able to access it from a Windows Server 2003 machine, so you install NWLink. You notice that after you installed NWLink, the Windows XP client machines that connect to Windows Server 2003 are taking longer to connect and read information. What can you do to ensure the best performance for the Windows XP clients? Install NWLink on the Windows XP machines. Install the Novell NetWare Client on the Windows XP machines. Move TCP/IP up in the binding order on the Windows Server 2003 machine. Install the Novel NetWare Client on the Windows Server 2003 machine.
13.	You are network administrator for a new company. Your LAN is connected to the Internet by a single T1 line. You obtain a single public IP address from your ISP. Your firewall services are outsourced to the ISP. The LAN includes five Windows XP Professional computers and one Windows Server 2003 computer named Server01. All Windows XP client computers are configured to use DHCP to obtain their IP configurations. Server01 is configured as a DHCP server and contains two network adapters. You connect one network adapter to the hardware for the ISP connection and connect the other network adapter to the LAN. You want client computers to access the Internet, including browsing the Web and file transfers via FTP. Which of the following configuration tasks must you complete? Install the DNS Server service. Install WINS Services. Install Routing and Remote Access Services (RRAS). Assign the public IP address to the external adapter.

Planning Network Traffic Management

14.	Users are complaining about slow network performance. Using Network Monitor, you have identified the source of the excessive traffic is inbound and outbound traffic from your DNS server. How would you identify the source of the excessive DNS traffic? Using the host IP addresses from Network Monitor, perform a tracert command to each host and determine the time it takes to get to each requested destination. Use System Monitor to watch performance counters on the DNS server and identify the cause of the slow performance. Use System Monitor to watch performance counters on the client machines to identify the machine that is using the DNS server heavily. Ping the DNS server using the –t option from different host machines to identify the subnet that is causing the increase in network traffic.
15.	You are using Network Monitor to analyze traffic on your Windows Server 2003 machine. You have a lot of data that has been captured, but you are looking for specific information. How do you accomplish this? Define a filter for the captured data. Open the trace in Notepad and do a global search for the information you are seeking. Export the data to a .cap file and view the reports in Excel. Set up the counters for the appropriate data.
