Exam MD-100 topic 3 question 27 discussion

C is correct, with network discovery off, a computer will not have other computers listed in Network in File Explorer, but it will also no longer appear in this list on other computers on the network.

The correct answer is C. Turn off network discovery. To prevent the computers of the research department from appearing in Network in File Explorer on Windows 10 computers in an Active Directory domain, you should turn off network discovery. Network discovery allows computers to discover and communicate with each other on the network, which can reveal the presence of other computers on the network. Answer A, Configure DNS to use an external provider, is not relevant to this scenario as it does not address the issue of preventing computers from appearing in Network in File Explorer. Answer B, Modify the %systemroot%\system32\drivers\etc\Networks file, is not relevant to this scenario as it is used to map network names to IP addresses and does not affect the visibility of computers on the network. Answer D, Disable the Network List Service, is not recommended as it can cause issues with network connectivity and is not necessary to prevent computers from appearing in Network in File Explorer.

The idea is to disable network discovery, but the technical question to do was not developed at all in the question. Fortunately!

You would have to turn off network discovery on every computer in the department, I assume? Or is that beyond what the question is looking for?

Turning off network discovery is correct.

C. Turn off network discovery.

When network discovery is on, this computer can see other network computers and devices and is visible to other network computers
