Which of the following are advantages of controller-based networks versus traditional networks? [Choose all that apply]

Question

Network devices function autonomously
The control and the data planes on each device are separated
Control plane is software-based
Features are configured for the network rather than per device

Answer 1

The advantages of controller-based networks versus traditional networks include the following:

1. The control and the data planes on each device are separated - This is a key feature of controller-based architectures, allowing for centralized control and more efficient data handling.

2. Control plane is software-based - In controller-based networks, the control plane is typically hosted in software, allowing for greater flexibility, programmability, and easier updates compared to traditional hardware-based control.

3. Features are configured for the network rather than per device - In a controller-based network, network-wide policies and configurations can be applied centrally, streamlining management and ensuring consistency across the network.

The option Network devices function autonomously is typically more characteristic of traditional networks, where each device operates independently. Therefore, it is not an advantage of controller-based networks.

So the correct advantages are:

• The control and the data planes on each device are separated
• Control plane is software-based
• Features are configured for the network rather than per device
