Which statements best describe the relationship between the control plane and forwarding plane? Choose Two.

The most suitable statements describing the relationship between the control plane and forwarding plane focus on their distinct roles within a network device.

The control plane is responsible for the decision-making processes within the network, such as routing protocol exchanges and maintaining the routing table, while the forwarding plane handles the actual transfer of packets based on the rules set by the control plane. They operate in tandem, where the control plane informs the forwarding plane how to handle traffic.

In this context, the statement about a rate limiter being configured by default is accurate, as network devices often implement rate limiting as a mechanism to manage traffic flow and maintain stability within the system. This can help protect against large spikes in traffic that could overwhelm the forwarding resources, ensuring that both control and forwarding functions can perform effectively.

Considering the operational dynamics, the statement regarding control traffic being preferred during congestion also holds true. This preference ensures that critical control plane communications, which are vital for maintaining network integrity and performance, are prioritized over routine data traffic.

Thus, the correct understanding encompasses that the control plane has a crucial role in ensuring that network devices can communicate essential information without disruption, and that mechanisms like rate limiting help maintain a balance between the two planes under varying traffic conditions.
