Network+ 4.8

One evening, you're up late working to meet a fast-approaching deadline when suddenly your Internet connection fails. Much of your work requires Internet access for research, but you belay the panic for a few moments to evaluate the situation:

• You try a couple of different Web sites in your browser, then open a different browser and try a couple of Web sites again. None of the sites will load.
• You check all of the cable connections between your computer and your network's demarc. Everything looks normal.
• You power cycle the modem and router by unplugging both devices from the electrical outlet, waiting a moment, plugging in the modem, waiting for it to establish a connec- tion with the ISP, then plugging in the router.
• You check the Network Connections status on your computer and confirm that you have a functioning connection with your network.
• You try again to navigate to a Web site in your browser, but the page still won't load.
• You open a Command Prompt window and ping one of Google's servers at 8.8.8.8. The
• ping works.
• You ping Google's Web site at google.com, but this time it doesn't work.
• You pull up an outage reporting Web site for your ISP on your smartphone, and find that a few hundred other people have reported the outage in your area, too.

With a quick adjustment, you get your Internet service functioning again and continue with your work. Which of the following did you do and why?

1. You switched out the Ethernet cable connecting your modem to your router because the cable was damaged.
2. You used ipconfig to release the IP address on your computer and get a new one from your network's DHCP service because your computer had a duplicate IP address.
3. You changed the DNS settings on your router to point to Google's DNS servers instead of the DNS servers of your ISP because the ISP's DNS servers were down.
4. You switched to a different ISP because the former ISP's service was unreliable.
5. You replaced the router with a new router you had ready to go, knowing that the old
6. router had already exceeded its life expectancy and had finally ceased to function.
7. You created an ad hoc network with another computer on your network and used that computer's access to the Internet to continue your research because the Wi-Fi radio on your computer had died and will need to be replaced.
8. You performed a factory reset on your modem so it would reinitiate a connection with the ISP.
9. You updated the default gateway on your computer because it was unable to communi- cate with the router.
10. You restarted your computer because Windows had updates that needed to be installed.
