Which characteristic is typical of a decentralized control plane?

It requires a dedicated out-of-band management network

Control and data planes are always physically separated

All control decisions are made by a single central controller

Each network device runs its own control plane protocols

Which design consideration is most relevant when evaluating control plane placement?

The physical location of the control plane relative to the data plane

The number of users in the network

The type of applications running on the network

The color of the network cables

What is a key trade-off of a decentralized control plane compared to a centralized one?

It eliminates the need for routing protocols

It simplifies policy enforcement but introduces a single point of failure

It reduces network resilience but improves scalability

It provides better resilience but can be more difficult to enforce consistent policies

Which characteristic is a primary advantage of a centralized control plane in network design?

Eliminates the need for any distributed protocols

Increased resilience due to no single point of failure

Reduced latency for all data plane forwarding decisions

Simplified policy enforcement and consistent state across the network

What is a common reason to adopt a hybrid control plane in network design?

To combine centralized policy enforcement with decentralized fast failover

To eliminate the need for any distributed routing protocols

To reduce the overall network complexity

To ensure that all devices have identical forwarding tables
