220-1102 Question 825
Single answerPrivate vs. publicA technician is troubleshooting a Windows 11 laptop in a small office. The user says they can print to the office printer and access shared files when working from home over VPN, but after bringing the laptop into the office and connecting to the company Wi-Fi, Windows prompted them to choose whether the network should be discoverable. The user selected the wrong option and now other office PCs cannot see this laptop for file sharing, even though internet access works. Which action should the technician take to restore normal local sharing while keeping the laptop connected to the office network?
- A
Change the network profile from Public to Private
- B
Disable IPv6 on the wireless adapter
- C
Set the connection to Metered
- D
Join the laptop to a workgroup
- E
Renew the DHCP lease from Command Prompt
Show answer and explanation
Correct answer: A
Explanation
This question tests practical understanding of Windows network location profiles. In Windows 10 and Windows 11, choosing Public versus Private affects how the system treats the network in terms of trust. A Public profile is intended for untrusted locations, such as coffee shops or airports, and typically restricts Network Discovery and File and Printer Sharing through firewall rules. A Private profile is intended for trusted local networks, such as home or office environments, and is the correct choice when users need to participate in local resource sharing. Microsoft documentation and Windows security best practices describe Public networks as more restrictive and Private networks as appropriate for trusted LANs. In this scenario, the user selected the wrong profile, so the best fix is to change the office Wi-Fi connection from Public to Private.
- A. Correct.
Correct. In Windows, a Private network profile is intended for trusted networks such as a home or office LAN. It typically allows Network Discovery and File and Printer Sharing to function more easily under the Windows Defender Firewall rules. If the office Wi-Fi was mistakenly set to Public, the laptop may remain reachable for internet access but appear hidden or blocked for local sharing tasks.
- B. Incorrect.
Incorrect. Disabling IPv6 is not the appropriate fix for a network profile problem. The issue described began after the user chose the wrong discoverability option, which maps to the Public versus Private profile behavior in Windows. Turning off IPv6 could create additional connectivity issues and does not address Windows sharing settings.
- C. Incorrect.
Incorrect. A metered connection affects how Windows uses data, such as limiting background downloads or updates. It does not switch the trust level of the network profile or restore local visibility for file and printer sharing. This is a common confusion because both settings are found in network properties.
- D. Incorrect.
Incorrect. Workgroups can be relevant for peer-to-peer sharing on small networks, but the scenario indicates the laptop previously worked and the problem started specifically after the wrong network-type selection. That points to the firewall and discovery behavior of the Public profile, not a missing or incorrect workgroup membership.
- E. Incorrect.
Incorrect. Renewing the DHCP lease can help with IP addressing problems, but the laptop already has internet access on the office Wi-Fi. Since the symptom is limited to local discoverability and sharing after the profile selection changed, DHCP renewal is unlikely to resolve the issue.
