QoS shaping
Suggested answer: C

Explanation:

According to the Aruba Documentation Portal1, the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.

This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second.Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port
