Chapter 5. Configuring Windows Networking > Review Question Answers

Review Question Answers

1.Answer B is correct. To renew IPv4, you have to use the ipconfig /renew command. Answer A is incorrect because the ipconfig command without any options only displays basic IP configuration information. Answer C is incorrect because the /renew6 option renews IPv6 IP addresses. Answer D is incorrect because the /release_and_renew option does not exist. Answer E is incorrect because the /registerdns option is how to get the computer to register itself with the DNS server.
2.Answer E is correct. The command to flush local cached DNS information is ipconfig /flushdns. Answer A is incorrect because the ipconfig command without any options only displays basic IP configuration information. Answer B is incorrect because the /renew option renews the IPv4 IP addresses. Answer C is incorrect because the /renew6 option renews IPv6 IP addresses. Answer D is incorrect because the /registerdns option is how to get the computer to register itself with the DNS server.
3.Answer C is correct. The two commands that show network connectivity to another computer are the ping command the tracert command. Answer A is incorrect because the ipconfig command without any options only displays basic IP configuration information. Answer B is incorrect because the arp command is used to view and manage IP address to MAC address mappings. The traceroute command is found on UNIX and Linux machines. Windows machines use tracert.
4.Answer B is correct. To show all IP configuration information, you must use the ipconfig /all command. Answer A is incorrect because the ipconfig command without any options only displays basic IP configuration information. Answer C is incorrect because the arp command is used to view and manage IP address. Answers D and E are incorrect because ping and tracert are commands used to test network connectivity.
5.Answer A is correct. By looking at the example, the address assigned to the computer is 169.254.3.103, which is an Automatic Private IP address. Automatic Private IP addresses begin with 169.254. Automatic Private IP addresses are assigned to Windows computers when they cannot find a DHCP server from which to get an address. Answer B is incorrect because although a gateway address might be needed to communicate with computers on another network, the gateway was not assigned because it could not find a DHCP server. Answer C is incorrect because this subnet mask was assigned when it could not find a DHCP server. Answer D is incorrect because you can determine the problem from the information provided in the example.
6.Answer D is correct. If you have a name resolution issue, the problem has to be with a DNS or WINS server or you have incorrect entries in your HOSTS or LMHOSTS files. Answer A is incorrect because if you can ping it by address, you have network connectivity to the server. So, it does not matter if the server is on the same subnet or a different subnet. Answer B is incorrect because you cannot block access to a computer by name but keep access by address. Answer C is incorrect because if the DHCP client service was not on, you would not be able to get any address from a DHCP server and are not able to connect to other hosts on the network.
7.Answer D is correct. If you want an address to be available from the Internet and be the same address for both IPv4 and IPv6, it must have a global unicast address that can be seen on the Internet. Answer A is incorrect because private addresses cannot be used on the public network such as the Internet. Answer B is incorrect because it has to be a single address assigned to a single computer, and not a multicast, which is used to broadcast to multiple addresses at the same time. Answer C is incorrect because a local address cannot be seen on the outside.
8.Answer D is correct. Because this person is traveling between two sites, the user needs to have a local address on each site. Therefore, you should let the local DHCP server hand out the addresses when she connects to each network. Answer A is incorrect because she can connect to one network. Therefore, the driver is working fine. Answer B is incorrect because this means that you are putting this computer directly on the Internet. Answer C is incorrect because running a troubleshooting wizard could be a lengthy process when the solution is simple.
9.Answer B is correct. To force the ping command to test a IPv6 connection, you need to use the -6 option. Answer A is incorrect because the –s option is used to specify a source address, which can come in handy when you have a computer with multiple network cards. Answer C is incorrect because the –a option is used to resolve the address to a host name. Answer D is incorrect because the –t option pings the specified host until it is stopped.
10.Answer C is correct. Link-local addresses are used by hosts when communicating with neighboring hosts on the same link. Answer A is incorrect because a global unicast address is an address that is equivalent to IPv4 public addresses so they are globally routable and reachable on the IPv6 portion of the Internet. Answer B is incorrect because a unique local unicast address is an IPv6 address that is equivalent to IPv4 private address spaces. Answer D is incorrect because the anycast address is an IPv6 unicast address that is assigned to multiple computers. When IPv6 addresses communication to an anycast address, only the closest host responds.
