A company plans to revamp its network infrastructure to enhance its 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?
Traditional network model with static configurations
Software-defined networking (SDN) is the correct answer because it decouples the control plane (which makes decisions about where traffic goes) from the data plane (which forwards the traffic), allowing for centralized, programmable management of the entire network. This enables dynamic configuration and rapid provisioning of services. A traditional network model is incorrect as it relies on static, device-by-device configuration. Network function virtualization (NFV) is a related but distinct concept focused on virtualizing network services (like firewalls or routers) to run on commodity hardware, rather than controlling the network's traffic flow. A content delivery network (CDN) is used to cache and deliver content from locations closer to the end-user to improve performance and availability, not for overall network management.
