A.

The issue being faced in this scenario is related to roaming between access points in a high-density environment. In such an environment, multiple access points are deployed in close proximity to cater to a large number of wireless clients. However, roaming between these access points can be challenging due to interference, signal strength, and other factors.

To resolve this issue, a feature on the wireless controller should have been incorporated in the design. Among the four options given, the most relevant feature to address this issue is RX-SOP, which stands for Receive Signal Overlapping Protection.

RX-SOP is a feature that enables access points to scan for neighboring access points and adjust their channel and power settings to minimize interference and improve roaming performance. This feature ensures that access points do not interfere with each other and provide a seamless roaming experience to the wireless clients.

802.11w is a feature that provides enhanced security for wireless communications by encrypting management frames. It is not directly related to the issue of roaming in a high-density environment.

AP Heartbeat Timeout is a feature that enables the wireless controller to detect access points that are not responding and take appropriate action. It is not directly related to the issue of roaming in a high-density environment.

Application Visibility Control is a feature that enables the wireless controller to identify and prioritize traffic based on the application type. It is not directly related to the issue of roaming in a high-density environment.

Therefore, the correct answer is A. RX-SOP.
