5.5.7 The sales department wants to create an intranet for all sales employees. Internet Information Services (IIS) is installed on CorpWeb and will be used to host the intranet site. Employees need the ability to access the web server using any of the following URLs: http://sales.private http://intranet.sales.private http://www.sales.private You created the sales.private zone on the CorpDC server. Now you need to allow clients to connect to the web server by creating the following records in the zone: Create an ALIAS (CNAME) record leaving the name blank. (This allows users to connect to the server using the sales.private URL.) Create an ALIAS (CNAME) record named intranet. Create an ALIAS (CNAME) record named www. When creating ALIAS records, use CorpWeb.CorpNet.com as the fully qualified domain name.

In Hyper-V Manager, select CORPSERVER. Right-click CorpDC and select Connect. In Server Manager, select Tools > DNS. Expand CORPDC. Expand the Forward Lookup Zones. Right-click the sales.private zone and select New Alias (CNAME). In the Alias name field, enter the alias name (to use the parent domain name for the alias, leave the field blank). Enter the fully qualified domain name of the host. Click OK. Repeat steps 6-9 to create additional records.

4.4.9 You are a network technician for a small corporate network. The employee in Office 1 says that after she added a pair of speakers to her workstation, she could no longer communicate with the computer in the Networking Closet. You need to diagnose and fix the problem. The following IP addresses are used in this lab: LocationComputer NameIP AddressNetworking ClosetServer192.168.0.10Office 1Office1192.168.0.30Office 2Office2192.168.0.31Support OfficeSupport192.168.0.32IT AdministrationITAdmin192.168.0.33Executive OfficeExec192.168.0.34LobbyGst-Lap192.168.0.35 In this lab, your task is to complete the following: Use the following troubleshooting tools to diagnose the problem in the network:The ping command utilityThe network activity lights for all networking devicesThe Network and Sharing Center in the Windows 10 or Windows 2016 operating system Fix the problem. Use the known good spares on the Shelf as necessary. Use the troubleshooting tools to confirm the resolution of the problem. If necessary, use Exhibits to see the network diagram and the wiring schematics of the network.

In Office 1, begin troubleshooting the problem by verifying the connectivity problem between the workstation and computer in the Networking Closet (pinging the computer in the Networking Closet fails). In Office 1, check the Networking and Sharing Center or the status lights on the NIC. The diagram in the Network and Sharing Center shows the network connection as disconnected from any network, and the link and status lights on the NIC also show it is disconnected. A disconnected status is displayed when the NIC does not have a connection to the network. Possible causes for a disconnected status include:Bad NICFaulty cableUnplugged cableSwitch or hub port either turned off or faulty Because the scope of the problem is currently limited to the Office 1, you should look for common errors or solutions that can be tried quickly. When the user added the speakers, she may have knocked the networking cable loose and disconnected it on accident. Confirm that the network cable is connected to the NIC and the wall plate. The network cable is plugged into the wall plate, but not to the motherboard's NIC. In Office 1, connect the network cable back into the motherboard's NIC. Check the status lights on the NIC. The lights show the connection is functioning normally. In Office 1, check the Networking and Sharing Center diagram. Ping the computer in the Networking Closet. The diagram in the Network and Sharing Center shows a connection to the network and internet, and the ping to the computer in the Networking Closet succeeds.

5.8.8 You are a network technician for a small corporate network. The network is connected to the internet and uses DHCP for address assignment. The employee in Office 1 reports that his workstation can communicate with some computers on the network, but not on the internet. You need to diagnose and fix the problem. In this lab, your task is to complete the following: Use the following troubleshooting tools to diagnose the problem in the network:The ping, ipconfig, or tracertcommand utilityThe Network and Sharing Center in the Windows 10 or Windows Server 2016 operating systemThe DHCP server console in the Windows Server 2016 operating system Fix the problem at the workstation, the DHCP server, or both as necessary. Use the troubleshooting tools to confirm that the problem is resolved. To see the network diagram and wiring schematics of the network, use Exhibits.

In Office 1, begin troubleshooting the problem by verifying the scope of the connectivity problem.From the workstation, ping CorpServer in the Networking Closet.Ping the Internet Service Provider (ISP) (Notice that the ping fails for both CorpServer and the ISP). In the IT Administration office, verify the connectivity problem between the workstation and all other workstations in the network (the ping to all other workstations in the network and the ISP succeeds). Both steps 1 and 2 confirm that there is not a physical connectivity problem in the local network and that the scope of the problem is most likely related to the IP configuration for the Office 1 workstation. On Office 1, open the command prompt and enter the ipconfig /all command to check the Ethernet configuration. You should notice the following problems:The subnet mask is incorrectly configured with 255.255.255.240. The workstation can only communicate with other hosts whose IP addresses have the same network address as determined by the local subnet mask. ITAdmin is 192.168.0.20, and Office 1 is 192.168.0.30. With 255.255.255.240 as a subnet mask, the network would only include addresses from 192.168.0.16 to 192.168.0.31. The IP address for CorpServer (192.168.0.10) and the router fall outside of this range.The DHCP Enabled line shows No. This means that the workstation has been configured with a static IP address.The DNS Servers line shows 163.128.78.108, which is not the address of either of the External DNS Servers. On Office 1, configure the network connection to request the IP address information from the DHCP server:Right-click the Network icon and select Open Network and Sharing Center.Select Ethernet.Select Properties.Select Internet Protocol Version 4 (TCP/IPv4).Select Properties.Select Obtain an IP address automatically.Select Obtain DNS server address automatically.Select OK.Select Close.Select Close. On Office 1, open the command prompt and enter ipconfig /all to check the Ethernet configuration. You should notice the line for DHCP Enabled shows Yes, a new IP address, the correct subnet mask, and the correct DNS Server. Confirm the resolution of the problem by pinging the ISP. The ping to the ISP succeeds.

4.4.6 You are a network technician for a small corporate network. The employee in Office 1 says he cannot communicate with the computer in Office 2, and has asked that you come to his office to fix the problem. In this lab, the following IP addresses are used: LocationComputer NameIP AddressNetworking ClosetServer192.168.0.10Office 1Office1192.168.0.30Office 2Office2192.168.0.31Support OfficeSupport192.168.0.32IT AdministrationITAdmin192.168.0.33Executive OfficeExec192.168.0.34LobbyGst-Lap192.168.0.35 In this lab, your task is to complete the following: Use the following troubleshooting tools to diagnose the problem in the network:The ping command utilityThe network activity lights for all networking devicesThe Network and Sharing Center in the Windows 10 or Windows 2016 operating system Fix the problem and, as necessary, use the known good spares on the Shelf. Use the troubleshooting tools to confirm the problem resolution. If necessary, use Exhibits to see the network diagram and the wiring schematics of the network

In Office 1, ping each workstation in the network. This should verify the connectivity problem between Office 1 and Office 2 (pinging the computers in the Networking Closet and Lobby succeeds, but the ping to Office 2 fails). The scope of the problem could be isolated to the computer in Office 2. In Office 2, ping each workstation in the network. Each ping attempt fails regardless of the remote workstation. Again, the scope of the problem could be isolated to the computer in Office 2. In the Networking Closet, confirm that the scope of the problem is limited to Office 2 by pinging each workstation in the network (pinging Office 1 and Lobby succeeds, but the ping to Office 2 fails). In Office 2, check the network connection in the Networking and Sharing Center or the status lights on the NIC. The diagram in the Network and Sharing Center shows the network connection as disconnected from any network, and the link and status lights on the NIC also show it is disconnected. A disconnected status is displayed when the NIC does not have a connection to the network. Possible causes for a disconnected status include:Bad NICFaulty cableUnplugged cableSwitch or hub port either disabled or faultyBecause the scope of the problem is currently limited to the Office 2, you should look for common errors or solutions that you can try quickly. Confirm that the network cable is connected to the NIC and the wall plate. Both ends of the cable are connected correctly. In Office 2, replace the cable between the workstation and the wall plate. After you replace the cable, the disconnected status is still displayed in the Network and Sharing Center. You could replace the NIC in Office 2, but you should continue to replace cables because you can test the results quickly. In the Networking Closet, check the switch to ensure that it is powered on. The power light for the device indicates that it is powered on. Also, since Office 1 can communicate through the switch, you know that the device is not turned off. In the Networking Closet, observe the activity lights for all ports on the switch. There are activity lights for other ports, yet there is a lack of activity for Port 4. Possible causes include:The cable between Office 2's patch panel port and the switch is bad or disconnected.Port 4 on the switch is disabled or shutdown. In the Networking Closet, confirm that the network cable is connected to Office 2's patch panel port and the switch. Both ends of the cable are connected correctly. In the Networking Closet, replace the patch panel cable, as you can test this solution quickly. The activity light for Port 4 now indicates network activity. In Office 2, check the network connection in the Networking and Sharing Center or the status lights on the NIC. The diagram in the Network and Sharing Center shows a connection to the network and internet, and the link and status lights on the NIC also show it is functioning normally. In Office 2, ping each workstation in the network. Each ping attempt succeeds regardless of the remote workstation. In Office 1, ping Office 2 to confirm the resolution of the original problem. The ping attempt is successful. Replacing the NIC in Office 2 and making a console connection to the switch to confirm if port 2 is disabled are two viable approaches for this problem. Yet, as indicated earlier, you should look for common errors or solutions that can you can test quickly. Admin Use Only: NP446B

5.8.7 You are a network technician for a small corporate network. The network is connected to the internet and uses DHCP for address assignment. The owner of the company in the Executive Office and a temporary employee in IT Administrator office both report that their workstations can communicate with some computers on the network, but cannot communicate with the internet. You need to diagnose and fix the problem. In this lab, your task is to complete the following: Use the following troubleshooting tools to diagnose the problem in the network:The ping, ipconfig, or tracertcommand utilityThe Network and Sharing Center in the Windows 10 or Windows Server 2016 operating systemThe DHCP server console in the Windows Server 2016 operating system Fix the problem at the workstation, the DHCP server, or both as necessary. Use the troubleshooting tools to confirm the resolution of the problem. To see the network diagram and the wiring schematics of the network, use Exhibits.

In the Executive Office, begin troubleshooting the problem by verifying the scope of the connectivity problem. From the workstation, ping the computer in the Networking Closet. The ping to the location fails. Ping the Internet Service Provider (ISP). The ping to the location fails. In the IT Administrator office, verify the connectivity problem between the workstation the Networking Closet computer and the ISP. (The pings to both locations fails). The problem is most likely related to the IP configuration for the network. In the Executive Office, open the command prompt and use the ipconfig /all command to check the Local Area Connection configuration. You should notice the following problems:The default gateway and DNS server addresses have not been configured on the workstation. This means that communication is limited to other computers on the local network.The DHCP Enabled line is Yes, meaning that the workstation is configured to use a DHCP server.The DHCP Server address line is not shown. This means that the workstation was unable to contact the DHCP server.The IP address is in the APIPA range (169.254.0.1 to 169.254.255.254). This means that the workstation assigned itself an IP address. The workstation will be able to communicate with other hosts on the local network that have also configured their own IP address through APIPA. In the Networking Closet, confirm that the DHCP service is enabled and activated for the local network.In Hyper-V Manager, select CORPSERVER. Expand the window to view all virtual machines.Right-click CorpDHCP and select Connect (maximize the window for easier viewing if desired).In Server Manager, select Tools > DHCP to start the DHCP console.Expand CorpDHCP.CorpNet.com.Expand IPv4. The down arrow for Scope [192.168.0.1] Subnet1 indicates that the scope is not active.Right-click Scope [192.168.0.1] Subnet1 and select Activate. The down arrow for the scope is gone, and the DHCP service for the local network is now active. In the Executive Office, open the command prompt and enter ipconfig /renew. This will request the new IP address information from the DHCP server, and it will reconfigure the settings for the Ethernet connection. Enter ipconfig /all to check the Ethernet configuration. You should notice the lines for the default gateway, DNS server, and DHCP server are now configured, along with a new IP address within the DHCP scope for the local network. In the Executive Office, confirm the resolution of the problem by pinging the ISP. The ping to the ISP succeeds. In the IT Administrator Office, repeat step 6 to fix the problem for that workstation.

4.4.8 You are a network technician for a small corporate network. Minutes ago, your entire building had a power blackout. The power has been partially restored, but there are still offices and closets without power. Employees in the Executive Office and the Support Office have called to report that they cannot access the internet or other computers on the network. You need to diagnose and fix the problem as it pertains to the network. The following IP addresses are used in this lab: LocationComputer NameIP AddressNetworking ClosetServer192.168.0.10Office 1Office1192.168.0.30Office 2Office2192.168.0.31Support OfficeSupport192.168.0.32IT AdministrationITAdmin192.168.0.33Executive OfficeExec192.168.0.34LobbyGst-Lap192.168.0.35 In this lab, your task is to complete the following: Use the following troubleshooting tools to diagnose the problem in the network:The ping command utilityThe network activity lights for all networking devicesThe Network and Sharing Center in the Windows 10 or Windows 2016 operating system Fix the problem.

If necessary, use Exhibits to see the network diagram and the wiring schematics of the network.

In the Executive Office, complete the following:Begin troubleshooting by verifying the connectivity problem between the workstation and all other workstations in the network (pinging to all other workstations in the network fails).Check the Network and Sharing Center or the status lights on the NIC. The diagram in the Network and Sharing Center shows the network connection as disconnected from any network. The link and status lights on the NIC also show it is disconnected.Brainstorm possible causes for a disconnected status. Some possibilities include the following:Bad NICFaulty cableUnplugged cableSwitch or hub port either turned off or faultyLook for common errors or solutions that you can test quickly. Confirm that the network cable is connected to the NIC and the wall plate. (Both ends of the cable are connected correctly.) In the Support Office, complete the following:Repeat the same troubleshooting steps you took in the Executive Office to duplicate results and discover the scope of the problem.With matching information from each office's workstation, the scope of the problem is shared between these two workstations and is likely shared with other workstations. Because the scope of the problem includes two offices, you should look for common errors or solutions that you can test quickly. In the Networking Closet, complete the following:Check the switch to ensure that it is powered on. The system light for the device indicates that it is powered off. Since the workstations in the Support Office and the Executive Office could not ping in the network, you can conclude that the device is turned off.Above the rack, select Back to switch to the back view of the rack.Check the power cable of the switch to ensure that it is plugged into the UPS. The switch is plugged into the UPS, but it is not plugged into the critical load section.Move the power cable from the non-critical load (Bank 2) outlet to an empty critical load (Bank 1) outlet.Above the rack, select Front to switch to the front view of the rack.Observe the power light and activity lights for all ports on the switch. The lights are all on and active (except for the wireless access point, as it is still connected to the non-critical load [Bank 2] on the UPS). In the Executive Office or the Support Office, complete the following:Check the Network and Sharing Center or the status lights on the NIC. The diagram in the Network and Sharing Center shows a connection to the network and internet. The lights on the NIC also show that it is functioning normally.Ping each workstation in the network. Each ping attempt now succeeds.

9.2.4 You are a network technician for a small corporate network. The switch in the networking closet was recently upgraded to a Power over Ethernet (PoE) switch. Because of this, the IP phones in the building no longer need an AC/DC adapter to function. In addition, the Support Office has requested to have an IP phone installed. In this lab, your task is to complete the following: In the Lobby and the Executive Office, complete the following:Disconnect the AC/DC adapter from the IP phone and the wall.Place the AC/DC power adapters on the Shelf.Confirm that the phones are still receiving power through PoE. Install an IP phone in the Support Office.Place the IP phone in the Workspace.Move the Ethernet cable from the computer to the LAN port on the phone.Connect an Ethernet cable from the workstation's NIC to the PC port on the phone.Make sure the Support computer is still connected to the internet.

The Network and Sharing Center should indicate a bad connection to the internet.Select Ethernet.Select Properties.Select Internet Protocol Version 4 (TCP/IPv4).Select Properties.Select Obtain an IP address automatically.Select Obtain DNS server address automatically.Click OK.Click Close.Click Close.Open the Network and Sharing Center to confirm the connection to the network and the internet for the workstation. The Network and Sharing Center should indicate an active connection to the local network and the internet.

5.1.7 You work as the IT administrator for a small corporate network. You need to configure the workstation in the Executive Office so it can connect to the local network and the internet. The workstation has two network interface cards. This will allow the workstation to connect to the local network (as shown in the Exhibits) and another small network, which is not yet built. In this lab, your task is to complete the following: Configure the IP version 4 TCP/IP settings for the network connections using the settings in the table below. Use the Network and Sharing Center in Windows to confirm that the workstation is properly connected to the small network and the Internet. TCP/IP SettingEthernetEthernet 2Subnet192.168.0.0/2410.0.0.0/16Host addressUse the lastvalid address on the subnet.Use the last valid address on the subnet.Default gateway addressChoose the appropriate address for the router as shown in the exhibits.Do not configure a default gateway value.DNS Server addressUse the address of an External DNS Server as shown in the exhibits.Do not configure a DNS value.

5.8.6 You are a network technician for a small corporate network. The network is connected to the internet and uses DHCP for address assignment. The employees in the Support Office and Office 2 report that their workstations can communicate with some computers on the network, but not on the internet. You need to diagnose and fix the problem. In this lab, your task is to complete the following: Use the following troubleshooting tools to diagnose the problem in the network:The ping, ipconfig, or tracertcommand utilityThe Network and Sharing Center in the Windows 10 or Windows Server 2016 operating systemThe DHCP server console in the Windows Server 2016 operating system Fix the problem at the workstation, the DHCP server, or both as necessary. Use the troubleshooting tools to confirm the resolution of the problem. To see the network diagram and the wiring schematics of the network, use Exhibits.

In the Support Office, begin troubleshooting the problem by verifying the scope of the connectivity problem. From the workstation, ping the computer in the Networking Closet and ping the internet service provider (ISP) (pinging the computer in the Networking Closet succeeds, but the ping to the ISP fails). In Office 2, verify the connectivity problem between the workstation and all other workstations in the network (the ping to all other workstations in the network succeeds, but the ping to the ISP fails). Both steps 1 and 2 confirm that there is not a physical connectivity problem in the local network. The problem is most likely related to the IP configuration for the network. In the Support Office, open the command prompt and enter ipconfig /all to check the Local Area Connection configuration. You should notice the following problems:The default gateway address is incorrectly configured with 192.168.0.4. This is why the workstation in this scenario can only communicate with hosts on the local network, but not on the internet.The DHCP Enabled line is Yes, meaning that the workstation is configured to use a DHCP server.The DHCP server address listed is 192.168.0.10. This is the correct DHCP server address. The workstation received addressing and default gateway information from the correct DHCP server. Therefore, the DHCP server has been configured to give out the wrong default gateway address. In the Networking Closet computer on CorpServer, open the CorpDHCP guest server and launch the DHCP console to reconfigure the settings for the DHCP scope as follows:In Hyper-V Manager, select CORPSERVER. Expand the window to view all virtual machines.Right-click CorpDHCP and select Connect.In Server Manager, select Tools > DHCP to start the DHCP console.Expand CorpDHCP.Expand IPv4.Expand Scope [192.168.0.1] Subnet1.Select Scope Options.Right-click 003 Router.Select Properties.In the default gateway address field, enter 192.168.0.5 and remove 192.168.0.4.Click OK to apply the change. In the Support Office, open the command prompt and enter ipconfig /renew. This will request the new IP address information from the DHCP server and reconfigure the settings for the Ethernet connection. Enter ipconfig /all to check the Ethernet configuration. You should notice the line for the default gateway is now correctly configured as 192.168.0.5. Confirm the resolution of the problem by pinging the ISP. The ping to the ISP succeeds. In Office 2, repeat steps 5-7 to fix the problem for the second workstation.

4.4.7 You are a network technician for a small network. The manager in the Support Office says she can't communicate with any computer in the network. You need to diagnose and fix the problem. The following IP addresses are used in this lab: LocationComputer NameIP AddressNetworking ClosetServer192.168.0.10Office 1Office1192.168.0.30Office 2Office2192.168.0.31Support OfficeSupport192.168.0.32IT AdministrationITAdmin192.168.0.33Executive OfficeExec192.168.0.34LobbyGst-Lap192.168.0.35 In this lab, your task is to complete the following: Use the following troubleshooting tools to diagnose the problem in the network:The ping command utilityThe network activity lights for all networking devicesThe Network and Sharing Center in the Windows 10 or Windows 2016 operating system Fix the problem. Use the known good spares on the Shelf as necessary. Use the troubleshooting tools to confirm the problem's resolution. If necessary, use Exhibits to see the network diagram and the wiring schematics of the network.

In the Support Office, ping the workstation in the IT Administration office and other workstations in the network (pinging all other workstations in the network fails). With the information from the Support manager and these ping results, the scope of the problem may be isolated to the workstation in the Support Office. In the IT Administration office, verify the problem by pinging the workstation in the Support Office and other workstations in the network (pinging all other workstations in the network is successful, but the ping to the Support workstation fails). This verifies that there is connectivity between all other workstations in the network, except for the Support Office. This confirms that the scope of the problem is limited to the Support Office. In the Support Office, open the Networking and Sharing Center or view the status lightson the NIC. The diagram in the Network and Sharing Center shows the network connection as disconnected from any network, and the link and status lights on the NIC also show it is disconnected. A disconnected status is displayed when the NIC does not have a connection to the network. Possible causes for a disconnected status include:Bad NICFaulty cableUnplugged cableSwitch or hub port either disabled or faulty Because the scope of the problem is currently limited to the Support Office, you should look for common errors or solutions that you can test quickly. Confirm that the network cable is connected to the NIC and the wall plate. Both ends of the cable are connected correctly. In the Support Office, replace the cable between the workstation and the wall plate. After you replace the cable, the disconnected status is still displayed in the Network and Sharing Center. You could replace the NIC in the Support Office, but you should continue to replace cables because you can test those results quickly. In the Networking Closet, check the switch to ensure that it is powered on. The power light for the device indicates that it is powered on. Also, since the workstation in the IT Administration office can communicate through the switch, you know that the device is not turned off. In the Networking Closet, observe the activity lights for all ports. There are activity lights for other ports, yet there is a lack of activity for Port 6. Possible causes include:The cable between the Support Office's patch panel port and the switch is bad or disconnected.Port 6 on the switch is disabled or shut down. In the Networking Closet, confirm that the network cable is connected to Support Office's patch panel port and the switch. Both ends of the cable are connected correctly. In the Networking Closet, replace the patch panel cable, as you can test this solution quickly. The activity light for Port 6 still does not indicate network activity.Making a console connection to the switch to confirm that port 6 is disabled is a viable approach for this problem, but the lab does not provide a console application to confirm the switch's port settings.

At the command prompt, enter tracert to recheck the path to the ISP.What do you learn from the results of tracert?

On CorpServer in the Networking Closet computer, mouse over the Network icon in the notification area.On CorpServer, the Network icon in the notification area appears normal, which indicates a connection to the local network and to internet. When you mouse over the Network icon, you see the details of this status. In the notification area, right-click the Network icon and select Open the Network and Sharing Center.The Network and Sharing Center diagram confirms that CorpServer is connected to the local network and the internet. Ping CorpServer (local workstation) and the ISP to verify connectivity to the internet as follows:Right-click Start and select Command Prompt (Admin) to open a command window.The ping to CorpServer (local workstation) and the ISP succeed, verifying a valid connection to the internet.At the command prompt, enter ipconfig /all to check the Ethernet configuration.Using ipconfig /all provides the following information about the vEthernet (External) on CorpServer:DHCP Enabled: No. This tells us that the server is configured with a static IP address and is not enabled for DHCPIPv4 Address: 192.168.0.10Subnet Mask: 255.255.255.0. The server is using the default subnet mask for the Class C IP address range.Default Gateway: 192.168.0.5. The router's internal interface is configured as the default gateway.At the command prompt, enter tracert to see the path to the ISP.Using tracert 65.86.1.1 verifies a path to the ISP through our default gateway. In the Executive Office, check the status of the link and network activity lights as follows:From the navigation tabs at the top, select Floor 1 Overview.Under Executive Office, select Hardware.Above the workstation, select Back to switch to the back view of the workstation.The link and network activity lights on the back of the workstation are on and blinking, indicating that there is a physical connection to the switch and there is activity on the connection. This points to a TCP/IP configuration problem. Verify the connectivity on the Exec workstation as follows:On the Exec monitor, select Click to view Windows 10.In the notification area, mouse over the Network icon.Right-click the Network icon and select Open the Network and Sharing Center.On the Exec workstation, the network icon in the notification area has a yellow warning sign with an exclamation point, which indicates a connection to the local network, but no access to the internet. When you select the Network icon, you see the details of this status. The Network and Sharing Center diagram confirms that Exec is connected to the local network, but has no internet access. On Exec, you are able to ping the local interface on Exec by name (since you don't know the IP address yet), but you can't ping CorpServer or the ISP. This indicates that Exec has a valid connection, but can't communicate with CorpServer or the ISP. Using ipconfig /all provides the following information about the Ethernet connection on Exec:DHCP Enabled: NoIPv4 Address: 192.168.0.62Subnet Mask: 255.255.255.240Default Gateway: 192.168.0.4This information provides us with at least two clues to the problem:The network is using DHCP, but this workstation is not enabled for DHCP.Given the workstation's current subnet mask, the IPv4 Address of the workstation and the default gateway are not on the same network. In addition, the subnet mask is not the default subnet mask for the Class C IP address range being used. With 255.255.255.240 as a subnet mask, the network would only include addresses from 192.168.0.48 to 192.168.0.63. The IP address for CorpServer (192.168.0.10) and the ISP fall outside of this range. The information in step 3 confirms that the default subnet mask for the Class C IP address range (255.255.255.0) is being used. After correcting the subnet mask on Exec, there are still no changes to the network icon or the diagram in the Network and Sharing Center. After correcting the subnet mask on Exec, you can now ping CorpServer, but you still can't ping the ISP. This indicates that you only have local connectivity. Use tracert 65.86.1.1. The command times out, indicating the following:The ICMP packets are not returning from the first hop (gateway) in its path to the ISP. Exec is not finding the gateway.The gateway address on Exec is not configured correctly. (The gateway address (router) on the network diagram is 192.168.0.5.) After configuring the correct gateway address on Exec, the network icon and the diagram in the Network and Sharing Center confirm that Exec is connected to the internet. Using the tracert command again returns a path to the ISP through the gateway. Since we have a valid connection to the internet, we will leave the static address for now while we troubleshoot in Office 1. In Office 1, the link and network activity lights on the back of the workstation are on and blinking. Once again, this points to a TCP/IP configuration problem. On Office1, the network icon and the diagram in the Network and Sharing Center indicate that Office1 is connected to the unidentified network and has no internet access. You are able to ping the local interface, but you can't ping CorpServer or the ISP. This indicates that Office1 has a valid connection to the local network. Using ipconfig /all provides the following information about the Ethernet connection:DHCP Enabled: Yes. This tells us that the workstation is configured to use a DHCP server.IPv4 Address: This address is in the APIPA range (169.254.0.1 to 169.254.255.254). This means that the workstation assigned itself an IP address instead of receiving one from the DHCP server. The workstation will only be able to communicate with other hosts on the local network that have also configured their own IP address through APIPA.Subnet Mask: 255.255.0.0. This is the default subnet mask for the APIPA address.Default Gateway: The address is blank. This means that communication is limited only to other workstations on the local network.DHCP Server line is not shown. This means that the workstation was unable to contact the DHCP server.DNS Servers line is not shown for IPv4.Since DHCP is enabled, the rest of the information should have come from the DHCP server. We can conclude that there is an issue with the DHCP server. On CorpDHCP, launch the DHCP console and activate the scope. On Office1, the ipconfig /renew command will request new IP address information from the DHCP server, and it will reconfigure the settings for the Ethernet connection. The ipconfig /all command will check the Ethernet configuration. You should notice the line for the default gateway, DNS server, and DHCP server, along with the new IP address, which is now within the DHCP scope for the local network. After activating the DHCP server and receiving a valid IP Address, you can now ping CorpServer from Office1, but you still can't ping the ISP. The tracert command times out on Office1, indicating that it can't get to the gateway. As noted above, the gateway should be 192.168.0.5. The ipconfig /all command shows the default gateway is set to 192.168.0.2, but we know it should be 192.168.0.5. Since this address is coming from DHCP, we need to check the DHCP server. On CorpDHCP, launch the DHCP console and reconfigure the settings for the DHCP scope. On Office1, the ipconfig /renew command will request new IP address information from the DHCP server, and it will reconfigure the settings for the Ethernet connection. Use the ipconfig /all command to check the Ethernet configuration. You should notice that the line for the default gateway is now configured correctly. The network icon and the diagram in the Network and Sharing Center indicate that Office1 is connected to the local network and the internet. When you ping the ISP to confirm resolution, the ping succeeds. On Exec, reconfigure the Ethernet connection to use DHCP. The ipconfig /all command now shows the IP address, default gateway, DNS server, and DHCP server that were provided by the DHCP server. The network icon and the diagram in the Network and Sharing Center indicate that Exec is connected to the corporate network with full internet access. Use tracert 65.86.1.1, which returns a path to the ISP through the gateway. The network is now fully functional, and your troubleshooting is complete.

5.4.3 You just installed the DHCP service on the CorpDHCP server. You configured two scopes. The scope for Building A, Subnet1, is configured on 192.168.0. The scope for Building B, Subnet2, is configured on 192.168.10. After activating the scopes, you find that clients on Subnet1 receive IP addressing information from the DHCP server, but clients on Subnet2 have IP addresses in the 169.254.0.0/16 range. You realize that DHCP messages are not being forwarded through the router. In this lab, your task is to complete the following: Use Routing and Remote Access to configure CorpServer2 as a DHCP relay agent by performing the following:Add the DHCP relay agent routing protocol.Add NetTeam as a DHCP relay agent interface.Set the boot threshold to 0.Configure the DHCP relay agent properties to identify 192.168.0.14 as the DHCP server.

5.9.8 In this lab, you will discover important facts about network communications by using the ping or tracert command utility. On ITAdmin, the IP address is configured, but not a default gateway address. The following local network IP addresses are used in this lab: LocationNameIP AddressNetworking ClosetServer192.168.0.10Office 1Office1192.168.0.30Office 2Office2192.168.0.31Support OfficeSupport199.92.0.33IT AdministrationITAdmin192.168.0.33Executive OfficeExec192.168.0.34LobbyGst-Lap192.168.0.35ISPExternal DNS Server163.128.78.93RouterInternal Router198.28.56.1 Complete this lab as follows: Right-click Start > Command Prompt (Admin) to open the command prompt. At the command prompt, enter ping 192.168.0.30 and press Enter to ping Office1. Does the test succeed? Enter ping 199.92.0.33 and press Enter to ping Support. Why does this test fail? Enter ping 192.168.0.5 and press Enter to ping the router's internal interface. Does the test succeed? Enter ping 163.128.78.93 and press Enter to ping the ISP. Why does this test fail? Trace the path between Exec and the internet router's interface as follows:From the top navigation tabs, select Floor 1 Overview.Under Executive Office, select Exec.Right-click Start > Command Prompt (Admin) to open the command prompt.At the command prompt, enter tracert 198.28.56.1 and press Enter. What addresses appear in the path between Exec and the internet router? Enter tracert 163.128.78.93 and press Enter to trace the path to one of the ISP's DNS servers. How does this path differ from the path you discovered in the previous step?

Right-click Start > Command Prompt (Admin) to open the command prompt. At the command prompt, enter ping 192.168.0.30 and press Enter to ping Office1. You can successfully ping the IP address of Office1 from ITAdmin. Enter ping 199.92.0.33 and press Enter to ping Support. You cannot ping Support from ITAdmin. Notice that the IP address for Support is on a different network (network 199.92.0.0 instead of network 192.168.0.0). Devices on the same local network must have IP addresses in the same network range. If you want to communicate with Support, you will need to change the IP address assigned to Support. Enter ping 192.168.0.5 and press Enter to ping the router's internal interface. You can successfully ping the router's internal interface from ITAdmin. Because ITAdmin and the router's address (192.168.0.5) are on the same network, the ping tests succeed. Enter ping 163.128.78.93 and press Enter to ping the external DNS Server. ITAdmin and the ISP are on a different network (network 192.168.0.0 and 163.128.78.0 respectively). Because ITAdmin does not have a default gateway set, it cannot communicate with devices on other networks. Trace the path between Exec and the internet router's interface as follows:From the top navigation tabs, select Floor 1 Overview.Under Executive Office, select Exec.Right-click Start > Command Prompt (Admin) to open the command prompt.At the command prompt, enter tracert 198.28.56.1 and press Enter. When you communicate with devices on other networks, the packets go first to the default gateway (the router between the two networks). The packets are sent to the router interface on the same network as the sending host and then to the next hop in the path as necessary. In this case, there are two IP addresses listed in the tracert output, but only one router (hop) between Exec and the internet router. The last address in the tracert output is the internet router. Enter tracert 163.128.78.93 and press Enter to trace the path to one of the ISP's DNS servers. When you trace the path between Exec and the ISP's DNS server, the path has additional hops. The first lines in the tracert output are the routers (hops) between Exec and the DNS server. The last address in the tracert output is the DNS server.

5.10.4 You are the administrator for the CorpNet.com domain. The CorpDC and CorpDC3 servers are the DNS servers for the domain. CorpDC resides in Building A, and CorpDC3 resides in Building B. Users in Building B report that they are unable to contact the CorpWeb server. In this lab, your task is to complete the following: Use nslookup to query DNS for the CorpWeb server using its full name (CorpWeb.CorpNet.com). What happens? Use nslookup to query the CorpDC3 DNS server for CorpWeb. What happens? What is the problem? How would you resolve this problem? How would you verify that the problem has been fixed?

Right-click Start and select Command Prompt (Admin). At the command prompt, enter nslookup CorpWeb.CorpNet.com and press Enter.The CorpDC DNS server responds with name resolution information for CorpWeb. Enter nslookup CorpWeb.CorpNet.com CorpDC3.CorpNet.com and Press Enter.The CorpDC3 DNS server responds that it can't find CorpWeb. CorpDC3 does not have a DNS record for CorpWeb. The information between the DNS databases is not consistent. Since this DNS zone is an Active Directory-integrated zone, this indicates that Active Directory is not synchronizing properly. You would likely attempt to force replication between the Active Directory Domain Controllers. If CorpDC held a primary zone and CorpDC3 held a secondary zone, you would likely initiate a zone transfer to make sure the DNS records were consistent between servers. To verify that the problem has been fixed, you can repeat step 3. The CorpDC3 DNS server should responds with name resolution information for CorpWeb.

5.5.8 You are the administrator for the CorpNet.com domain. The CorpDC and CorpDC3 servers are the DNS servers for the domain. You are responsible for CorpDC, which resides in Building A. Users report that they are unable to contact the CorpWeb server. In this lab, your task is to complete the following: Ping the CorpWeb server using its full name of CorpWeb.CorpNet.com. What happens? Ping the CorpWeb server using its IP address 192.168.0.15. What happens? Create any DNS records needed to fix the problem.Host name: CorpWebIP address: 192.168.0.15 Use the ping command to verify that the problem is fixed.

Right-click Start and select select Command Prompt (Admin). At the command prompt, enter ping CorpWeb.CorpNet.com and press Enter. Notice that the ping is unable to find CorpWeb. Type ping 192.168.0.15 and press Enter. This time the ping succeeds using the IP address, indicating that there is a problem with the CorpWeb DNS record. In Hyper-V Manager, select CORPSERVER. Resize the window to view all virtual machines. Right-click CorpDC and select Connect (maximize the window for easier viewing if desired). In Server Manager, select Tools > DNS. Expand CORPDC. Expand Forward Lookup Zones. Right-click CorpNet.com and select New Host (A or AAAA). In the Name field, enter CorpWeb. In the IP Address field, enter the 192.168.0.15. Select Create associated pointer (PTR) record to automatically create the PTR record for the new host. Select Add Host. Select OK. Select Done to close the New Host dialog. From the Command Prompt window on CorpServer, enter ping CorpWeb.CorpNet.comand press Enter. Now the ping succeeds.
