A company plans to revamp its network infrastructure to enhance the ability to centrally manage network traffic and resources while also dynamically adapting to changing business needs. Which networking approach should the company implement to gain control over traffic flow and allow for the rapid provisioning of network services?
Network function virtualization
Traditional network model with static configurations
Software-defined networking (SDN) is the proper choice because it separates the control plane from the data plane, granting centralized management of the network. This central control facilitates fast, programmatically efficient network configuration changes, which traditional models that rely on individual device configurations cannot match. Network function virtualization focuses on optimizing network services themselves rather than providing dynamic traffic management and control, while a content delivery network is a distributed server system designed to serve content to users with high availability and high performance.
