Implementing, Managing, and Maintaining a Microsoft Windows Server 2003 Network Infrastructure

Question 1.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. The ITCertKeys.com network contains a print server named ITCertKeys-PR01 that has a built-in network interface. A ITCertKeys.com user named Andy Reid is a member of the Research and Development department. Andy Reid complains that he cannot print to a print device attached to ITCertKeys-PR01.

You have received instruction to ensure that Andy Reid can print to the print device. First you verify that the IP address for ITCertKeys-PR01 is correct and that the latest drivers for the print device are installed. You now want to verify that the print jobs are being sent to the correct MAC address for ITCertKeys-PR01.

What should do?

A. On ITCertKeys-PR01, run the net session command.
B. On ITCertKeys-PR01, run the netstat command.
C. On ITCertKeys-PR01, run the netsh command.
D. On ITCertKeys-PR01, run the netcap command.

Answer: D

Explanation:
Netstcap.exe is a command line tool that could be used to capture the network traffic. A filter can be created to be used during the capture to determine the MAC address the print jobs are being sent to. The Network Monitor Capture Utility ( Netcap.exe) can be used to capture network traffic in Network Monitor. Netcap provides capture abilities only from a command prompt; to open the resulting capture (.cap) files, you must use the full Network Monitor interface. Netcap is installed when you install the Support tools that are on the Windows XP CD-ROM. Netcap provides capture abilities that are similar to the version of Network Monitor that is included with the Windows Server products; however, you must use Netcap at a command prompt. Netcap installs the Network Monitor driver and binds it to all adapters when you first run the Netcap command.

Incorrect Options:
A: The net session command can be used to view the computer names and user names of users on a server, to see if users have files open, and to see how long each user's session has been idle. Net session manages server computer connections - used without parameters, net session displays information about all sessions with the local computer.
B: The netstat command is not a utility to use when troubleshooting NetBIOS names, but is used to display TCP/IP and port information.
C: The Network Shell utility (Netsh.exe) can perform a wide range of system configuration tasks. You can use commands in the Netsh Interface IP context to configure the TCP/IP protocol (including addresses, default gateways, DNS servers, and WINS servers) and to display configuration and statistical information.

Question 2.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of two subnets. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. All servers are located in a central data center that uses a single IP subnet and all client computers are located in one subnet. The data center contains two routers named ITCertKeys-SR01 and ITCertKeys-SR02, two domain controllers named ITCertKeys-DC01 and ITCertKeys-DC02, and two file servers named ITCertKeys-SR03 and ITCertKeys-SR04.

The IP addresses of these servers are indicated in the table below.
Host name IP address
ITCERTKEYS-DC01 10.10.10.1
ITCERTKEYS-DC02 10.10.10.2
ITCERTKEYS-SR01 10.10.1.1
ITCERTKEYS-SR02 10.10.1.2
ITCERTKEYS-SR03 10.10.11.1
ITCERTKEYS-SR04 10.10.11.2

You have received instruction from the CIO to install a new database server in the data center. You install Windows Server 2003 on a new server computer named ITCertKeys-DB01 and hand it over to a database administrator named Dean Austin.

Dean Austin installs Microsoft SQL Server 2005 and makes some changes to the TCP/IP settings on ITCertKeys-DB01 as shown in the following table.
Parameter Value
IP address 10.10.1.3
Subnet mask 255.255.255.0
Default gateway 10.10.1.2

Later, Dean Austin complains that ITCertKeys-DB01 cannot communicate with the other servers in the data center. All other servers in the data center can communicate with the other servers as well as the client computers. You log on to ITCertKeys-DB01 and attempt to ping ITCertKeys-DC01 but you receive the following error message: "Destination host unreachable".

What should you do to ensure that ITCertKeys-DB01 can communicate with the other computers in the ITCertKeys.com network?

A. Configure ITCertKeys-DB01 with a default gateway of 10.10.1.1.
B. Configure ITCertKeys-DB01 with a subnet mask of 255.255.0.0.
C. Configure ITCertKeys-DB01 with an IP address of 10.10.10.3.
D. Configure ITCertKeys-DB01 with an IP address of 10.10.11.3.

Answer: B

Explanation:
Large networks are subdivided to create smaller subnetworks to reduce overall network traffic by keeping local traffic on the local subnet and sending all nonlocal traffic to the router. In order to create a subnetwork, we need to have a system for addressing that allows us to use the network ID and host ID within the class-based system. This is accomplished through the use of a subnet mask. To determine the appropriate custom subnet mask (typically referred to simply as subnet mask) for a network, you must first:
1. Determine the number of host bits to be used for subnetting.
2. Determine the new subnetted network IDs.
3. Determine the IP addresses for each new subnet.
4. Determine the appropriate subnet mask.

Incorrect Answers:
A: You need to assign the correct subnet mask to ensure connectivity.
C, D: The problem in this scenario is not a faulty IP address. It is the appropriate subnet mask that has to be determined to enable connectivity.

Question 3.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of two subnets named Subnet A and Subnet B. Subnet A and Subnet B are connected by a router. All computers on the ITCertKeys.com network are configured with static IP addresses. All network servers run Windows Server 2003 and all client computers run Windows XP Professional. ITCertKeys.com hires a new Sales manager named Amy Wilson. You install a new client computer named ITCertKeys-WS291 for Amy Wilson. You then add ITCertKeys-WS291 to Subnet A. The relevant portion of the network is configured as shown in the exhibit.

However, Amy Wilson complains that ITCertKeys-WS291 cannot communicate with other hosts on the network.

What should you do to ensure that ITCertKeys-WS291 can communicate with all local and remote computers on the ITCertKeys.com network?

A. Configure ITCertKeys-WS291 with a default gateway of 192.168.28.84.
B. Configure ITCertKeys-WS291 with a default gateway of 192.168.2.1.
C. Configure ITCertKeys-WS291 with a subnet mask of 255.255.255.128.
D. Configure ITCertKeys-WS291 with a subnet mask of 255.255.255.192.

Answer: C

Explanation:
It is evident from the exhibit that the file server and ITCertKeys-WS291 have a different subnet mask. This is the reason why they cannot communicate with each other. You must therefore change the subnet mask of ITCertKeys-WS291 to 255.255.255.128.

Incorrect Answers:
A, B: The problem is not the gateway IP address that is faulty, but rather the subnet mask.
D: This option suggests the correct object that has to be changed, but it gives the wrong subnet mask.

Question 4.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. ITCertKeys.com has its headquarters in Chicago and branch offices in Dallas and Miami. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. You work in the Miami branch office. The network at the Miami branch office consists of 25 different subnets, each with a maximum of six computers. The network administrator at headquarters has allocated the 192.168.3.0/24 network address to the Miami branch office. You install a new server named ITCertKeys-SR21 in the Miami branch office. You need to configure the Internet Protocol (TCP/IP) properties for ITCertKeys-SR21. You configure ITCertKeys-SR21 with an IP address of 192.168.3.44.

What subnet mask should you use?

A. A subnet mask of 255.255.255.0.
B. A subnet mask of 255.255.255.128.
C. A subnet mask of 255.255.255.192.
D. A subnet mask of 255.255.255.240.
E. A subnet mask of 255.255.255.248.

Answer: E

Explanation:
The network address is: 192.168.2.0/24, which means 11111111.11111111.11111111.0 in binary. Therefore, you can use the last octet to configure the 30 subnets and 6 hosts in each Subnet You need only six host PCs. When you convert to binary, it is: 00000111. As a result, you use 3 bits. This leaves 5 bits for the subnets 11111000 converted to decimal:
128+64+32+16+8=248, therefore the subnet mask will be: 255.255.255.248.

Question 5.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. ITCertKeys.com has its headquarters in Chicago and a branch office in Dallas. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. You work in the Dallas branch office. The network at the Dallas branch office consists of a single subnet that contains 150 client computers and 12 servers. The network administrator at headquarters has allocated the 10.10.0.0/16 network address to the Dallas branch office. You have received instruction from your manager to place all servers at the Dallas branch office into a separate subnet that uses the 192.168.10 public addressing scheme. Your manager asks you to make allowance for a maximum of 30 servers in the new subnet.

Which subnet mask should you use for the new subnet?

A. 255.255.255.224
B. 255.255.255.240
C. 255.255.255.248
D. 255.255.255.252
E. 255.255.255.254

Answer: A

Explanation:
A 255.255.255.224 subnet mask gives five host address bits, so the maximum number of host addresses is 2 ^ 5 - 2 = 30 host addresses. Thus 255.255.255.224 is the only subnet mask that will allow for sufficient IP addresses in case of further growth, whilst still conserving as many current addresses as possible.

Question 6.
DRAG DROP
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. You have installed a new server named ITCertKeys-SR06 on the network. The relevant portion of the network is shown on the exhibit.

You want to configure ITCertKeys-SR06 with a valid static IP configuration. ITCertKeys-SR06 must be able to communicate with all hosts on the network and on the internet. You also need to configure ITCertKeys-SR06 to use the DNS server on the local subnet for name resolution. In addition, you must configure redundancy for name resolution.

How should you configure ITCertKeys-SR06?
To answer drag the appropriate IP addresses and Subnet masks to the appropriate places.

Answer:

Explanation:
The Class C address 192.168.0.100 has to be the IP address to enable ITCertKeys-SR06 to communicate with all hosts on the network and on the internet as 192.168.0.1, 192.168.0.2 and 192.168.0.110 are already in use. 192.168.5.2 and 192.168.5.100 are on the wrong subnet, and besides, 192.168.5.12 is already in use. The subnet mask for this Class C address is 255.255.255.0. The default gateway should be 192.168.0.1. To configure redundancy for name resolution, configure the preferred DNS server/primary address as 192.168.0.2, and the alternate DNS server/secondary address as 192.168.5.2.

Question 7.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. ITCertKeys.com has its headquarters in Chicago and branch offices in Dallas and Miami. You work in the Miami branch office.

The Miami branch office has a file server named ITCertKeys-SR25 that hosts critical documents. ITCertKeys-SR25 is configured with a DHCP client reservation. ITCertKeys.com users from all three offices download documents from ITCertKeys-SR25. One day ITCertKeys.com users complain that they cannot access the documents on ITCertKeys-SR25. You discover that the DHCP server has failed. The DHCP server is located at headquarters. You have received instruction from the CIO to ensure that ITCertKeys-SR25 is available even if it is unable to obtain or renew a lease from the DHCP server.

How could you accomplish this task?

A. On the DHCP server, increase the DHCP lease period.
B. Configure alternate IP settings for ITCertKeys-SR25 on the Alternate Configuration tab of the
Internet Protocol (TCP/IP) properties.
C. Configure the DHCP scope in the 169.254.0.1. - 169.254.255.254 range.
D. On the DHCP server, configure the DHCP 001 Resource Location Servers reservation option for ITCertKeys-SR25.

Answer: B

Explanation:
Windows Server 2003 includes the Alternate Configuration feature. The Windows Server 2003 servers can be configured to use an alternate static IP configuration if a DHCP server is unavailable. When a DHCP client determines that the DHCP server is unavailable, it will automatically change over and also configure the TCP/IP stack with the static address information specified on the Alternate Configuration tab of the Internet Protocol (TCP/IP) properties.

Incorrect Answers:
A: Increasing the lease period would result in DHCP clients requesting leases less frequently, but won't guarantee that ITCertKeys-SR25 will be available when the DHCP server is down.
C: Modifying the DHCP scope to the 169.254.0.1. - 169.254.255.254 range will still be reliant on the DHCP server.
D: Configuring the DHCP 001 Resource Location Servers reservation option for ITCertKeys-SR25 on the DHCP server will not ensure that ITCertKeys-SR25 will receive an IP address or have the IP address renewed.

Question 8.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. The ITCertKeys.com network contains a server named ITCertKeys-SR34. ITCertKeys-SR34 is configured as a DHCP server and has been authorized in Active Directory. The Telnet service has been installed and started on ITCertKeys-SR34.

One day ITCertKeys.com users complain that they cannot access network resources. Your investigations reveal that the DHCP Server service on ITCertKeys-SR34 has stopped. You install the administrative tools on a client computer named ITCertKeys-WS291 and log on to the computer. When you open the DHCP console on ITCertKeys-WS291 and attempt to connect to ITCertKeys-SR34, you receive an error message that states: "Cannot find the DHCP Server." You then attempt to ping ITCertKeys-SR34 but fail.

How can you connect to the DHCP Server service on ITCertKeys-SR34 by using the DHCP console on ITCertKeys-WS291?

A. Establish a Telnet session to ITCertKeys-SR34 and then run the net start dhcp command.
B. Establish a Telnet session to ITCertKeys-SR34 and then run the net start dhcpserver command.
C. Establish a Telnet session to ITCertKeys-SR34 and then run the ipconfig /renew command.
D. On ITCertKeys-WS291, run the netsh dhcp server\\ ITCertKeys-SR34 show server command.

Answer: B

Explanation:
You can start the DHCP Server service by executing the Net Start Dhcpserver command at the command prompt. Telnet is a protocol that enables an Internet user to log on to and enter commands on a remote computer linked to the Internet, as if the user were using a text-based terminal directly attached to that computer. Telnet is part of the TCP/IP suite of protocols. The term telnet also refers to the software (client or server component) that implements this protocol. Given the fact that you can ping ITCertKeys-SR34 you should then establish a Telnet session to ITCertKeys-SR34 and then run the appropriate command.

Question 9.
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. The ITCertKeys.com network contains a server named ITCertKeys-SR51 that is configured as a print server for a print device that has a built-in network interface. The print device is used by the Sales
department to print Sales reports.

A ITCertKeys.com user named Clive Allen is a member of the Sales department. Clive Allen complains that he cannot print to the print device attached to ITCertKeys-SR51. You verify that the IP address for ITCertKeys-SR51 is correct and that the correct drivers for the print device are installed. You now want to verify that the print jobs are being sent to the correct MAC address for ITCertKeys-SR51.

You log on to ITCertKeys-SR51. What should you do next?

A. Run the net session command.
B. Run the netstat command.
C. Run the netsh command.
D. Run the netcap command.

Answer: D

Incorrect Options:
A: The net session command can be used to view the computer names and user names of users on a server, to see if users have files open, and to see how long each user's session has been idle. Net session manages server computer connections - used without parameters, net session displays information about all sessions with the local computer.
B: The netstat command is not a utility to use when troubleshooting NetBIOS names, but is used to show what ports your computer is listening on.: -R is used to reload your LMHOSTS file located in %systemroot%\system32\drivers\etc., -r will show you which name resolutions have been answered via broadcasts, and which have been answered via
a NetBIOS name server, -RR switch of the command utility refreshes your NetBIOS
name with a configured WINS server.
C: The Network Shell utility (Netsh.exe) can perform a wide range of system configuration tasks. You can use commands in the Netsh Interface IP context to configure the TCP/IP protocol (including addresses, default gateways, DNS servers, and WINS servers) and to display configuration and statistical information.

Question 10.
Network Topology Exhibit:
LAN Settings Exhibit:
You work as the network administrator at ITCertKeys.com. The ITCertKeys.com network consists of a single Active Directory domain named ITCertKeys.com. All servers on the ITCertKeys.com network run Windows Server 2003 and all client computers run Windows XP Professional. The ITCertKeys.com network contains a Microsoft Internet Security and Acceleration (ISA) Server computer named ITCertKeys-SR01, a DNS server named ITCertKeys-SR02, a DHCP server named ITCertKeys-SR03, a file server named ITCertKeys-SR21, and a Web server named ITCERTKEYS-SR25. ITCertKeys-SR25 also serves as a central antivirus server.

ITCertKeys-SR21 is located on the 10.10.11.0 subnet and ITCertKeys-SR25 is located in the perimeter network. ITCertKeys-SR21 contains antivirus software that checks for new virus definitions on ITCertKeys-SR25 every hour. You can also access ITCertKeys-SR25 through a virus update Web page to perform manual virus definition updates. ITCertKeys-SR03 suffers a catastrophic failure and is removed from the network. Due to budgetary constraints, a replacement for ITCertKeys-SR03 will only be acquired in the next financial year. You need to redesign network addressing scheme, and change the IP addresses for ITCertKeys-SR01 to the addresses shown in the Network Topology exhibit.

ITCertKeys-SR02 contains the new host (A) resource records for ITCertKeys-SR01. You receive reports about a new virus threat and want to protect the network immediately by manually downloading the new virus definitions to ITCertKeys-SR21. you log on to ITCertKeys-SR21 but discover that you cannot access the virus update Web page on ITCertKeys-SR25. The static TCP/IP configuration on ITCertKeys-SR21 uses ITCertKeys-SR02 as the preferred DNS server. You confirm that ITCertKeys-SR01 is configured properly. On ITCertKeys-SR21, you view the Internet Explorer LAN settings that are shown in the LAN Settings exhibit.

What should you do to allow ITCertKeys-SR21 to connect to ITCertKeys-SR25?

A. At a command prompt on ITCertKeys-SR21, run the ipconfig /flushdns command.
B. In the LAN settings of Internet Explorer on ITCertKeys-SR21, select the Automatically detect settings check box.
C. At a command prompt on ITCertKeys-SR01, run the ipconfig / flushdns command.
D. At a command prompt on ITCertKeys-SR01, run the ipconfig /registerdns command.

Answer: A

Explanation:
Running the ipconfig /flushdns command will flush and reset the DNS resolver cache which is necessary to allow connection. Run this command on ITCertKeys-SR21 to connect to ITCertKeys-SR25.

Incorrect Answers:
B: Selecting the "Automatically detect settings" checkbox is not going to allow ITCertKeys-SR21 to connect to WWW.
C: The ipconfig /flushdns command flushes and resets the DNS resolver cache. This is not what is necessary.
D: The ipconfig /registerdns command refreshes all DHCP leases and registers any related DNS names. This option is available only on Windows 2000 and newer computers that run the DHCP Client service. This is not going to allow ITCertKeys-SR21 to connect to WWW when it is run on ITCertKeys-SR01.
