Explanation

Software-defined networking (SDN) is a network architecture that decouples the control plane from the data plane, enabling centralized network management and programmability. Compared to a traditional network, one of the security-related benefits that SDN provides is centralized network administrator control. This means that the network administrator can monitor, configure, and secure the entire network from a single point of authority, using software applications and policies. This reduces the complexity, inconsistency, and vulnerability of the network, as well as the human errors and misconfigurations. Centralized network provisioning is not a security- related benefit, but rather an operational benefit of SDN. It means that the network administrator can provision and deploy network resources and services faster and easier, using software commands and automation. Reduced network latency when scaled is not a security-related benefit, but rather a performance benefit of SDN. It means that the network can handle more traffic and data without compromising the speed and quality of service, using software optimization and load balancing. Reduced hardware footprint and cost is not a security-related benefit, but rather an economic benefit of SDN. It means that the network can use less physical devices and components, such as routers and switches, and rely more on software functions and
