Chapter 6.4.8 Practice Questions

Put the network troubleshooting steps in the proper order.

1)Identify the scope of the problem 2) Check IP address configuration 3) Check hardware configuration 4) Perform communication tests

You manage a Windows system connected to a business network that uses switches and multiple subnets. You connect a workstation to the 192.168.1.0/24 subnet. The workstation can communicate with some hosts on the private network, but it cannot communicate with other hosts. You enter ipconfig /all in Command Prompt and see the following output: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : mydomain.local Description . . . . . . . . . : Broadcom network adapter Physical Address . . . . . . . : 00-AA-BB-CC-74-EF DHCP Enabled . . . . . . . . . : No Autoconfiguration Enabled. . . : Yes IPv4 Address . . . . . . . . . : 192.168.1.102(Preferred) Subnet Mask . . . . . . . . . : 255.255.255.0 Default Gateway. . . . . . . . : 192.168.2.1 DNS Servers. . . . . . . . . . : 192.168.2.20 What should you do?

Edit the IPv4 properties and change the default gateway

The Windows Network Diagnostics tool analyzes a computer's network connection and verifies connectivity. When connected to a domain, what does the Network Map display?

It displays your computer, the domain, and the internet.

You have a computer running Windows that is connected to a domain network. After reconfiguring the static address of an internal web server named WEB3, your computer can no longer connect to WEB3. But other users are still able to connect to the same web server. You need to be able to connect to the website on the WEB3 server. Which of the following actions should you take?

Run the ipconfig /flushdns command

You have a computer that runs Windows and is connected to a domain network with a DHCP server. One day you find that your computer cannot connect to any network resources. You run the ipconfig command and find that the network connection has been assigned the address of 169.254.12.155 with a mask of 255.255.0.0. Which of the following actions should you take?

Run the ipconfig /release and ipconfig /renew commands

Your network has just transitioned from IPv4 to IPv6. IPv6 configuration is performed automatically using stateful DHCPv6. A DNS server on your network provides name resolution for IPv6. Your Windows system is having problems communicating on the network. You would like to receive new configuration information from the DHCP server as well as remove all old DNS entries in your local DNS cache. Which of the following actions should you take? (Select two. Each answer is part of the complete solution.)

Run the ipconfig /release6 and ipconfig /renew6 commands. Run the ipconfig /flushdns command

You have a Windows laptop that uses DHCP for IPv4 addressing information. You need to see the IPv4 address, subnet mask, and DNS server addresses that the network connection is currently using. Which of the following actions should you take? (Select two. Each answer is a complete solution.)

Run the netsh command. Run the ipconfig and ipconfig /all commands

Network and Sharing Center

Shows the network status and a graphical representation of network connections

You manage a Windows system connected to a business network that uses switches and multiple subnets. One day you find that the computer is unable to connect to the internet, but it can communicate with a few other computers on the local subnet. You enter ipconfig /all in Command Prompt and see the following output: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : mydomain.localDescription . . . . . . . . . . : Broadcom network adapterPhysical Address . . . . . . . . : 00-AA-BB-CC-74-EFDHCP Enabled . . . . . . . . . . : YesAutoconfiguration Enabled. . . . : YesIPv4 Address . . . . . . . . . . : 169.254.155.1(Preferred)Subnet Mask . . . . . . . . . . : 255.255.0.0Default Gateway. . . . . . . . . :DNS Servers. . . . . . . . . . . : What should you do?

Verify that the DHCP server is up and functional
