What action object is utilized to throttle traffic on a SonicWall firewall?

Bandwidth Management (BWM) is the correct action object to throttle traffic on a SonicWall firewall. This feature allows for the allocation of bandwidth to different types of traffic or users based on predefined policies. By setting up BWM, administrators can limit the amount of bandwidth available to specific applications or services, which helps to ensure optimal network performance and prevent any single application or user from monopolizing the available bandwidth.

In the context of SonicWall, BWM provides granular control over the network environment, enabling the prioritization of critical applications while restricting non-essential traffic. This capability is particularly useful in environments with varying demands on network resources, such as during peak usage times, where traffic management becomes crucial to maintaining service quality.

Other choices serve different functions: Content Filtering is focused on controlling access to websites based on content categories; Traffic Shaping improves the flow of packets through a network by smoothing out bursts of traffic but may not explicitly throttle bandwidth; and Access Rules regulate which traffic can enter or leave the network based on security policies. While these aspects are integral to managing a network's health and performance, they do not specifically address bandwidth throttling in the same way that Bandwidth Management does.
