Which of the following options is used to control North/South traffic in policy management?

The correct answer, which involves using IPLists, is essential for managing North/South traffic in policy management. IPLists allow organizations to define and manage traffic based on IP addresses. This is crucial in scenarios where the traffic flow is moving in and out of data centers or cloud environments, typically referred to as North/South traffic.

North/South traffic generally pertains to the communication between the internal network and external networks, such as the internet. By utilizing IPLists, administrators can specify which IP addresses or ranges are permitted or denied access, effectively securing the perimeter of the network and controlling how external entities can interact with the internal resources.

In contrast, whileFirewall Rules, Network Segmentation, and Access Control Lists may also play vital roles in overall network security and traffic management, they do not specifically focus on managing North/South traffic in the same way as IPLists. Firewall Rules are broader and often govern traffic flows at a higher level, while Network Segmentation separates resources within the network itself, typically handling East/West traffic. Access Control Lists can function similarly to IPLists but are more commonly associated with device or interface-level controls rather than specifically managing North/South traffic flows.
