Which of the following can be configured in the GUI setup wizard? (Select Three)

The ability to configure a WLAN (Wireless Local Area Network) in the GUI setup wizard is particularly significant as it directly influences how wireless clients access the network and interact with the organization's resources. The WLAN configuration typically involves setting parameters such as the SSID (Service Set Identifier), security protocols (like WPA2 or WPA3), and the type of authentication. This setup is crucial for establishing a wireless network and ensuring that users can connect and communicate with the network securely.

While VLANs, DHCP servers, and firewall policies are vital components of network setup and management, they often require more detailed configurations and customizations that might not be fully addressed in a basic GUI setup wizard. Configuring these elements usually involves deeper networking knowledge and is often performed in the advanced settings or through command line interfaces for more specific use cases. Thus, WLAN setup is often prioritized in GUI wizards to allow quick and straightforward initial access to the network for users.
