Exam 200-301 topic 1 question 1014 discussion

I would go with C.

C is best answer. Overall, separating the control plane from the data plane within an SDN network provides greater control, flexibility, scalability, and security, making it an ideal solution for large, complex, and dynamic networks.

Reduces cost , routers and switches can be less expensive since we have a different control plane , they don't need expensive CPUs , plus centralized control and so on. My vote is B!

it´s C

In cloud computing, the control plane is the layer that handles tasks like creating and distributing routing policies. For instance, in Amazon Web Services (AWS), the control plane supplies administrative APIs for CRUD operations. A few examples of control plane tasks include creating S3 buckets and launching EC2 instances.

The advantage of separating the control plane from the data plane is that it reduces overall network complexity. This separation allows for centralized control and management of the network through a controller, making it easier to manage and configure the network. By centralizing control, administrators can make changes to network policies and configurations without needing to touch individual network devices. This simplifies network management and reduces the risk of misconfigurations and inconsistencies that can occur when managing individual devices separately.

C. decreases overall network complexity

It reduces the cost form manpower with SDN period but that is not the question. It will minimize configuration but the network will still be complex. Virtual machines are going to be created from a management plane. Data is confined to the control plane and below. I vote A.

C seems the most logical answers

I would go with B
