220-1102 Question 132
Single answerNetwork and Sharing CenterA technician is troubleshooting a Windows 10 laptop that can access the internet and browse shared folders on other PCs in the office. However, coworkers cannot open the Public folder on this laptop, and the laptop does not appear under Network when other users browse the workgroup. The technician confirms the laptop is connected to the correct office Wi-Fi SSID. Which action in Network and Sharing Center is MOST likely to resolve the issue?
- A
Change the network profile from Public to Private
- B
Disable IPv6 on the wireless adapter
- C
Set up a new broadband connection
- D
Configure a manual DNS server address
Show answer and explanation
Correct answer: A
Explanation
This scenario points to a Windows network profile issue rather than a connectivity failure. In a Public network profile, Windows applies stricter firewall and sharing defaults, commonly disabling network discovery and file sharing to reduce exposure on untrusted networks. In a business office where local sharing is required, setting the network to Private is the most appropriate fix. In Windows 10, technicians can verify this through Network and Sharing Center and related advanced sharing settings, where network discovery and file/printer sharing are managed according to the active profile. Microsoft documentation and standard Windows networking best practices distinguish Public networks as untrusted and Private networks as trusted environments intended for local discovery and sharing.
- A. Correct.
Correct. In Windows, if a network is set to the Public profile, network discovery and file/printer sharing are typically disabled by default for security. Changing the network profile to Private in Network and Sharing Center or related network settings enables a more trusted profile appropriate for office or home environments, allowing the PC to be discovered and shared resources such as the Public folder to be accessed more easily.
- B. Incorrect.
Incorrect. Disabling IPv6 is not the appropriate fix for a system that already has working network connectivity and can reach other shared folders. IPv6 settings are unrelated to the common issue of a Windows device being hidden from network browsing because of the selected network profile.
- C. Incorrect.
Incorrect. The laptop already has a functioning wireless connection and internet access, so creating a new broadband connection would not address discoverability or file sharing. This option reflects confusion between internet connectivity setup and Windows sharing profile settings.
- D. Incorrect.
Incorrect. DNS configuration affects name resolution for internet and network resources, but it would not normally prevent the laptop from appearing under Network or sharing its Public folder when the core issue is that the network is treated as Public rather than Private.
