What is a key function of station isolation in a VLAN setup?

In a VLAN setup, a key function of station isolation is to prevent direct traffic between clients on different Access Points (APs) that share the same SSID. This is crucial for enhancing network security, as it ensures that devices connected to the same network cannot communicate with each other directly, reducing the risk of eavesdropping and unauthorized access to sensitive data.

By implementing station isolation, an organization can maintain a higher level of privacy for users on its wireless network. This is particularly important in environments such as public Wi-Fi hotspots, offices, or schools, where multiple users may connect to the same network and where safeguarding against data breaches is a priority.

The other options do not accurately describe the function of station isolation; they either imply unrestricted communication or focus on performance enhancements rather than the core security aspect of isolating client traffic.
