Which two are benefits of controller-based networking versus traditional networking? (Choose two.)

Controller-based networking, often associated with Software-Defined Networking (SDN), centralizes control and management. This centralization allows for simplified configuration and automation, significantly reducing the potential for human error compared to traditional networking, where devices are configured individually. Therefore, "Controller-based reduces configuration complexity, while traditional increases the potential for errors" is correct. Furthermore, controller-based networking centralizes key IT functions like policy enforcement, traffic engineering, and network monitoring. This contrasts with traditional networks, which typically rely on distributed management across many individual devices. Thus, "Controller-based centralizes key IT functions, while traditional requires distributed management" is also correct. The other options are incorrect: Controller-based networking aims to optimize, not necessarily increase, bandwidth usage. While it can improve reliability, stating it allows for "fewer network failures" while traditional "increases failure rates" is an oversimplification; both can fail. Software costs can vary, and it's not a universal truth that controller-based inflates them or traditional decreases licensing costs.
