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?
- You switched out the Ethernet cable connecting your modem to your router because the cable was damaged.
- 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.
- 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.
- You switched to a different ISP because the former ISP's service was unreliable.
- You replaced the router with a new router you had ready to go, knowing that the old
- router had already exceeded its life expectancy and had finally ceased to function.
- 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.
- You performed a factory reset on your modem so it would reinitiate a connection with the ISP.
- You updated the default gateway on your computer because it was unable to communi- cate with the router.
- You restarted your computer because Windows had updates that needed to be installed.
