You have just connected a new computer to your network. The network uses static IP addressing. You find that the computer can communicate with hosts on the same subnet, but not with hosts on a different subnet. No other computers are having a problem. Which of the configuration values would you most likely need to change?
Default gateway Check the default gateway setting on the computer. The default gateway value is used for sending packets to other subnets. If the value is incorrect, then the packets will not be sent to the correct router. In this scenario, the host can communicate with other hosts on the same subnet, meaning that the IP address and subnet mask are correctly configured. The DNS server address is likely not the problem as name resolution is not mentioned in the scenario. In addition, if name resolution were a problem, it could affect access to both local and remote hosts.

Under which circumstances would using the Last Known Good option be most likely to correct the problem?
If you made a system change and then the startup fails before the logon screen
You have a small wireless network with less than 50 client computers. You upgraded the hardware on two wireless devices so you can use a better security standard than WEP. Now you need to implement the new security standard. You need the greatest amount of security with the least amount of effort, and without replacing any of the wireless infrastructure. What should you do? (Select two.)
Implement WPA2-AES Configure each client with the same key In this case, implementing WPA2 with AES and using the same pre-shared key on each client provides the greatest amount of security with the least amount of effort, and does not require the replacement of any of the wireless infrastructure. WPA2- Enterprise uses 802.1x for authentication and requires the configuration of an authentication server. WPA2 is more secure than WPA-PSK.
A user reports that he can't browse to a specific Web site on the Internet. From his computer, you find that a ping test to the Web server succeeds. A trace route test shows 17 hops to the destination Web server. What is the most likely cause of the problem?
Incorrect DNS server address In this scenario, a ping test to the Web site succeeds, while accessing the Web site through the browser does not work. Users type host names in the browser to go to Web sites, and host names must be translated to IP addresses by a DNS server. Either the workstation is using the wrong address for the DNS server, the DNS server is not available, or the DNS server does not have an entry for the Web site. Because the ping and trace route tests work, you know that the IP address, subnet mask, and default gateway values are correct.

You're trying to access your office network with your Windows workstation from home using your organization's virtual private network (VPN). Your DSL modem has connected to your ISP, but you can't connect to your office network. You issue the ipconfig command from the command prompt and learn that your system has been assigned an IP address of 169.254.1.12. What's causing the problem?
Your ISP's DHCP server isn't working
Your home network is connected to the Internet through a 512 Mbps DSL line. Your ISP provided you with a small office/home office (SOHO) router that provides four 100 Mbps Ethernet ports for your home office and one DSL port for connecting the network to the Internet. The SOHO router has a built-in DHCP server that is used to automatically configure workstations with an IP address, default gateway address, and DNS server address. However, today you are unable to access the Internet. The browser reports that it can't find the URLs you are requesting. Using the ipconfig command, you've verified that the workstation is receiving correct IP address parameters. You tried entering tracert 137 .65.1.2 at a command prompt and found that you're able to reach this server on the Internet without any issues. What is causing this problem?
Your ISP's DNS server is down. Because your workstation is able to receive correct IP parameters from the built-in DHCP server, you know that the home office side of the SOHO router is working correctly. The fact that you're able to trace the route from your workstation to a server on the Internet using its IP address indicates that routing is working properly. This, coupled with the browser error message, would indicate that the most likely problem is a down or malfunctioning DNS server. You could test this hypothesis by trying to access a Web site using an IP address in the URL instead of a domain name.
Which of the following utilities would you use to correct cross-linked clusters within the file system on a Windows workstation?
