070-291 Implementing, Managing, and Maintaining a Microsoft Windows Server 2003 Network Infrastructure Exam: 070-291 Demo Edition CERT MAGIC 1http://www.certmagic.com070-291QUESTION: 1You work as the network administrator at Certmagic.com. The Certmagic.com networkconsists of a single Active Directory domain named Certmagic.com. All servers on theCertmagic.com network run Windows Server 2003 and all client computers runWindows XP Professional. The Certmagic.com network contains a print server namedCertmagic-PR01 that has a built-in network interface. A Certmagic.com user namedAndy Reid is a member of the Research and Development department. Andy Reidcomplains that he cannot print to a print device attached to Certmagic-PR01. You havereceived instruction to ensure that Andy Reid can print to the print device. First youverify that the IP address for Certmagic-PR01 is correct and that the latest drivers forthe print device are installed. You now want to verify that the print jobs are being sentto the correct MAC address for Certmagic-PR01. What should do?A. On Certmagic-PR01, run the net session command.B. On Certmagic-PR01, run the netstat command.C. On Certmagic-PR01, run the netsh command.D. On Certmagic-PR01, run the netcap command.Answer: DExplanation:Netstcap.exe is a command line tool that could be used to capture the network traffic. Afilter can be created to be used during the capture to determine the MAC address theprint jobs are being sent to. The Network Monitor Capture Utility ( Netcap.exe) can beused to capture network traffic in Network Monitor. Netcap provides capture abilitiesonly from a command prompt; to open the resulting capture (.cap) files, you must usethe full Network Monitor interface. Netcap is installed when you install the Supporttools that are on the Windows XP CD-ROM. Netcap provides capture abilities that aresimilar to the version of Network Monitor that is included with the Windows Serverproducts; however, you must use Netcap at a command prompt. Netcap installs theNetwork Monitor driver and binds it to all adapters when you first run the Netcapcommand.Incorrect Options:A: The net session command can be used to view the computer names and user namesof users on a server, to see if users have files open, and to see how long each user'ssession has been idle. Net session manages server computer connections - used withoutparameters, 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 systemconfiguration tasks. You can use commands in the Netsh Interface IP context toconfigure the TCP/IP protocol (including addresses, default gateways, DNS servers, andWINS servers) and to display configuration and statistical information.2http://www.certmagic.com070-291Reference:Microsoft Knowledge Base: 306794: How to Install the Support Tools from theWindows XP CD-ROM Network Monitor is provided with Windows Server productsand Microsoft Systems Management Server (SMS).

The Certmagic.com networkconsists of two subnets. All servers on the Certmagic.com network run WindowsServer 2003 and all client computers run Windows XP Professional. All servers arelocated in a central data center that uses a single IP subnet and all client computers arelocated in one subnet. The data center contains two routers named Certmagic-SR01 andCertmagic-SR02, two domain controllers named Certmagic-DC01 and Certmagic-DC02, and two file servers named Certmagic-SR03 and Certmagic-SR04. The IPaddresses of these servers are indicated in the table below.Host nameIP addressCERTMAGIC-DC0110.10.10.1CERTMAGIC-DC0210.10.10.2CERTMAGIC-SR0110.10.1.1CERTMAGIC-SR0210.10.1.2CERTMAGIC-SR0310.10.11.1CERTMAGIC-SR0410.10.11.2You have received instruction from the CIO to install a new database server in the datacenter. You install Windows Server 2003 on a new server computer named Certmagic-DB01 and hand it over to a database administrator named Dean Austin. Dean Austininstalls Microsoft SQL Server 2005 and makes some changes to the TCP/IP settings onCertmagic-DB01 as shown in the following table.ParameterValueIP address10.10.1.3Subnet mask255.255.255.0Default gateway10.10.1.2Later, Dean Austin complains that Certmagic-DB01 cannot communicate with the otherservers in the data center. All other servers in the data center can communicate with theother servers as well as the client computers. You log on to Certmagic-DB01 andattempt to ping Certmagic-DC01 but you receive the following error message:"Destination host unreachable". What should you do to ensure that Certmagic-DB01can communicate with the other computers in the Certmagic.com network?3http://www.certmagic.com070-291A. Configure Certmagic-DB01 with a default gateway of 10.10.1.1.B. Configure Certmagic-DB01 with a subnet mask of 255.255.0.0.C. Configure Certmagic-DB01 with an IP address of 10.10.10.3.D. Configure Certmagic-DB01 with an IP address of 10.10.11.3.Answer: BExplanation:Large networks are subdivided to create smaller subnetworks to reduce overall networktraffic by keeping local traffic on the local subnet and sending all nonlocal traffic to therouter. In order to create a subnetwork, we need to have a system for addressing thatallows us to use the network ID and host ID within the class-based system. This isaccomplished through the use of a subnet mask. To determine the appropriate customsubnet 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 subnetmask that has to be determined to enable connectivity.Reference:Deborah Littlejohn Shinder, Dr. Thomas W. Shinder, Chad Todd and Laura Hunter,MCSA/MCSE: Exam 70-291: Implementing, Managing, and Maintaining a WindowsServer 2003 Network Infrastructure Guide & DVD Training System, p. 57QUESTION: 3You work as the network administrator at Certmagic.com. The Certmagic.com networkconsists of two subnets named Subnet A and Subnet B. Subnet A and Subnet B areconnected by a router. All computers on the Certmagic.com network are configuredwith static IP addresses. All network servers run Windows Server 2003 and all clientcomputers run Windows XP Professional. Certmagic.com hires a new Sales managernamed Amy Wilson. You install a new client computer named Certmagic-WS291 forAmy Wilson. You then add Certmagic-WS291 to Subnet A. The relevant portion of thenetwork is configured as shown in the exhibit.4http://www.certmagic.com070-291However, Amy Wilson complains that Certmagic-WS291 cannot communicate withother hosts on the network. What should you do to ensure that Certmagic-WS291 cancommunicate with all local and remote computers on the Certmagic.com network?A. Configure Certmagic-WS291 with a default gateway of 192.168.28.84.B. Configure Certmagic-WS291 with a default gateway of 192.168.2.1.C. Configure Certmagic-WS291 with a subnet mask of 255.255.255.128.D. Configure Certmagic-WS291 with a subnet mask of 255.255.255.192.Answer: CExplanation:It is evident from the exhibit that the file server and Certmagic-WS291 have a differentsubnet mask. This is the reason why they cannot communicate with each other. Youmust therefore change the subnet mask of Certmagic-WS291 to 255.255.255.128.Incorrect Answers:A, B: The problem is not the gateway IP address that is faulty, but rather the subnetmask.D: This option suggests the correct object that has to be changed, but it gives the wrongsubnet mask.Reference:Deborah Littlejohn Shinder, Dr. Thomas W. Shinder, Chad Todd and Laura Hunter,MCSA/MCSE: Exam 70-291: Implementing, Managing, and Maintaining a WindowsServer 2003 Network Infrastructure Guide & DVD Training System, p. 575http://www.certmagic.com070-291QUESTION: 4You work as the network administrator at Certmagic.com. The Certmagic.com networkconsists of a single Active Directory domain named Certmagic.com. Certmagic.comhas its headquarters in Chicago and branch offices in Dallas and Miami. All servers onthe Certmagic.com network run Windows Server 2003 and all client computers runWindows XP Professional. You work in the Miami branch office. The network at theMiami branch office consists of 25 different subnets, each with a maximum of sixcomputers. The network administrator at headquarters has allocated the 192.168.3.0/24network address to the Miami branch office. You install a new server namedCertmagic-SR21 in the Miami branch office. You need to configure the InternetProtocol (TCP/IP) properties for Certmagic-SR21. You configure Certmagic-SR21with 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: EExplanation:The network address is: 192.168.2.0/24, which means11111111.11111111.11111111.0 in binary.Therefore, you can use the last octet to configure the 30 subnets and 6 hosts in eachsubnet You need only six host PCs. When you convert to binary, it is: 00000111. As aresult, 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.Reference:Deborah Littlejohn Shinder, Dr. Thomas W. Shinder, Chad Todd and Laura Hunter,MCSA/MCSE: Exam 70-291: Implementing, Managing, and Maintaining a WindowsServer 2003 Network Infrastructure Guide & DVD Training System, p.57QUESTION: 5You work as the network administrator at Certmagic.com. The Certmagic.com networkconsists of a single Active Directory domain named Certmagic.com. Certmagic.comhas its headquarters in Chicago and a branch office in Dallas. All servers on theCertmagic.com network run Windows Server 2003 and all client computers runWindows XP Professional. You work in the Dallas branch office. The network at theDallas branch office consists of a single subnet that contains 150 client computers and12 servers. The network administrator at headquarters has allocated the 10.10.0.0/166http://www.certmagic.com070-291network address to the Dallas branch office. You have received instruction from yourmanager to place all servers at the Dallas branch office into a separate subnet that usesthe 192.168.10 public addressing scheme. Your manager asks you to make allowancefor a maximum of 30 servers in the new subnet. Which subnet mask should you use forthe new subnet?A. 255.255.255.224B. 255.255.255.240C. 255.255.255.248D. 255.255.255.252E. 255.255.255.254Answer: AExplanation:A 255.255.255.224 subnet mask gives five host address bits, so the maximum numberof host addresses is 2 ^ 5 - 2 = 30 host addresses. Thus 255.255.255.224 is the onlysubnet mask that will allow for sufficient IP addresses in case of further growth, whilststill conserving as many current addresses as possible.Reference:Deborah Littlejohn Shinder, Dr. Thomas W. Shinder, Chad Todd and Laura Hunter,MCSA/MCSE: Exam 70-291: Implementing, Managing, and Maintaining a WindowsServer 2003 Network Infrastructure Guide & DVD Training System, p. 62QUESTION: 6DRAG DROPYou work as the network administrator at Certmagic.com. The Certmagic.com networkconsists of a single Active Directory domain named Certmagic.com. All servers on theCertmagic.com network run Windows Server 2003 and all client computers runWindows XP Professional. You have installed a new server named Certmagic-SR06 onthe network. The relevant portion of the network is shown on the exhibit.7http://www.certmagic.com070-291You want to configure Certmagic-SR06 with a valid static IP configuration. Certmagic-SR06 must be able to communicate with all hosts on the network and on the internet.You also need to configure Certmagic-SR06 to use the DNS server on the local subnetfor name resolution. In addition, you must configure redundancy for name resolution.How should you configure Certmagic-SR06? To answer drag the appropriate IPaddresses and Subnet masks to the appropriate places.8http://www.certmagic.com070-291Answer:9http://www.certmagic.com070-291Explanation:The Class C address 192.168.0.100 has to be the IP address to enable Certmagic-SR06to 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 areon the wrong subnet, and besides, 192.168.5.12 is already in use. The subnet mask forthis Class C address is 255.255.255.0. The default gateway should be 192.168.0.1. Toconfigure redundancy for name resolution, configure the preferred DNS server/primaryaddress as 192.168.0.2, and the alternate DNS server/secondary address as 192.168.5.2.Reference:J. C.
