What software-defined architecture plane assists network devices with making packet-forwarding decisions by providing Layer 2 reachability and Layer 3 routing information?

Answer options

Correct answer: B

Explanation

The control plane is responsible for routing and forwarding decisions by providing essential connectivity and routing information, making it the correct choice.
