220-1102 Operating Systems Practice Question
A technician needs to configure a Windows 10 workstation to use a proxy server for internet access. Which Control Panel applet should be used?
⚠ Common exam trap
Many exam-takers confuse the Network and Sharing Center (which handles adapter-level settings like IP and DNS) with the Internet Options applet (which handles application-level proxy settings), leading them to incorrectly select 'Change adapter settings' when the question specifically asks for proxy configuration.

Correct answer & explanation
✓
Internet Options -> Connections tab -> LAN settings
The proxy server settings for internet access in Windows 10 are configured through the Internet Options applet. On the Connections tab, clicking the 'LAN settings' button opens the Local Area Network (LAN) Settings dialog, where you can enable 'Use a proxy server for your LAN' and specify the proxy address and port. This is the correct path because Internet Options manages system-wide HTTP/HTTPS proxy configurations that apply to most applications using WinHTTP or WinINET.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Internet Options -> Connections tab -> LAN settings
Why this is correct
Internet Options (inetcpl.cpl) is the Control Panel shell for the WinINET API. On the Connections tab, the 'LAN settings' button opens the Local Area Network (LAN) Settings dialog, which provides the 'Use a proxy server' check box along with fields for the proxy address and port, plus an optional bypass list for local addresses. This writes the system-wide WinINET proxy configuration that many Windows applications honor.
- ✗
Network and Sharing Center -> Change adapter settings
Why it's wrong here
The Network and Sharing Center is a status dashboard for network discovery and active network profiles. 'Change adapter settings' lists installed network interfaces; right-clicking a NIC and choosing Properties exposes TCP/IP stack options (IPv4/IPv6) and client services, but no proxy fields. Proxy server settings are not bound to a physical or virtual adapter, so this path cannot configure them.
- ✗
Device Manager -> Network adapters
Why it's wrong here
Device Manager is the management console for hardware devices and their drivers. The 'Network adapters' node lets you update, disable, roll back, or view the properties of a NIC driver, including resource and power management options. It has no concept of application-layer HTTP traffic forwarding, so proxy server configuration is entirely outside its scope.
- ✗
Windows Firewall -> Advanced settings
Why it's wrong here
Windows Defender Firewall with Advanced Settings (wf.msc) is used to author inbound and outbound filter rules based on programs, ports, or IP addresses. It operates on the packet and session layers to allow or block traffic, but it does not redirect or forward traffic through an intermediary proxy. Configuring a proxy is about egress path selection, not filtering, so this tool cannot perform that task.
