What is an advantage of using SDN versus traditional networking when it comes to security?

The correct answer is D. SDN creates a unified control point making security policies consistent across all devices, and. Software-Defined Networking (SDN) centralizes the control plane, allowing for a unified point to manage and enforce security policies. This centralization ensures consistent application of security rules across all devices in the network, reducing the risk of misconfigurations. I

Explanation

Software-Defined Networking (SDN) centralizes the control plane, allowing for a unified point to manage and enforce security policies. This centralization ensures consistent application of security rules across all devices in the network, reducing the risk of misconfigurations. In traditional networking, security configurations are applied on a per-device basis, which increases complexity and the likelihood of human error, especially in large networks.
