Which two are advantages of a controller-based network architecture compared to traditional architectures? (Choose two.)

Controller-based network architectures centralize control, allowing for automation of configuration tasks through programmatic interfaces. This significantly reduces manual effort and potential for human error. They also provide increased scalability and management options because the control plane is decoupled from the data plane, enabling easier expansion and more efficient oversight of network resources. Seamless connectivity to virtual machines is a feature of virtualization, not exclusive to controller-based networks. While some controller-based solutions may offer enhanced security features, it's not a universal primary advantage over traditional architectures in preventing all DoS attacks. Support for complex IP addressing schemes is a function of routing protocols and network design, not a direct advantage of controller-based architectures.
