Network teams want centralized, policy-driven virtual networking instead of configuring each device only with isolated static settings. Which concept describes that model?
Select an answer to reveal the explanation.
Short Explanation
SDN is the difference between yelling new rules into every closet switch versus posting policy once from a control brain. The control plane sets intent; devices forward accordingly. Living only on box-by-box static configs is what SDN was meant to escape.
Full Explanation
Software-defined networking centralizes network policy in a control plane while forwarding devices implement that intent, enabling programmable virtual networking at cloud scale. Relying solely on per-box static configuration does not provide the same policy agility. Cloud architectures commonly use SDN concepts for overlays, segmentation, and automated network services.
