Configure networking

Thought experiments

In these thought experiments, demonstrate your skills and knowledge of the topics covered in this chapter. You can find the answers to these thought experiments in the next section.

Scenario 1

You are troubleshooting connectivity problems on a new laptop that has been added to a local, small business network that already includes eight other computers. Three of these eight are laptops that have always connected without issues. The new laptop can connect when plugged in directly to the router with an Ethernet cable, but it cannot connect wirelessly.

Answer the following questions related to how you would troubleshoot this issue:

1. What do suspect is causing this problem?

2. Do you think that the troubleshooter in the Network And Sharing Center can resolve this problem?

3. If the Internet Connection troubleshooter uncovers the issue but can’t resolve it, where would you turn next and why?

Scenario 2

You support multiple mobile users who connect to a dozen wireless networks a month and print to the printers on those networks regularly. Users complain that they have to choose their printers manually when using those networks and that sometimes they choose the wrong ones. Not only is this annoying, but because they print sensitive documents, it’s also a security issue for your company.

Beyond that, users have connected to wireless networks they’d rather have their laptops forget. The list of networks is quite long and they want you to remove entries for networks they’ll never use again (or networks that offered poor connectivity, such as one they have connected to in the past at a hotel or conference center). In the case of networks with poor connections, they’d rather default to broadband.

Regarding this scenario, answer the following questions:

1. What feature do you enable on the users’ Windows 10 laptops to enable the network connection to define the printer to which the users will print by default, and what two services does this feature rely on?

2. When a user is in a hotel where she’s stayed before, and that user has also connected to the hotel’s free Wi-Fi, what must you do to forget that network so that the user can default to broadband when she stays there next time?

Scenario 3

A client has a large library of media that contains thousands of music files. He wants to share that media in such a way as to be able to access it over the Internet from another computer he owns and keeps at his office. He’s enabled the appropriate options in Media Player on both computers. However, he can’t get sharing to work.

1. What do you need to do regarding the firewall so that this client can allow Media Player to share music files over the Internet?

2. Will you perform the required task in Windows Firewall or Windows Firewall with Advanced Security?

3. Will you need to be logged on as an Administrator to do this?
