200-301 Question #281: Real Exam Question with Answer & Explanation

Question

What are two benefits of controller-based networking compared to traditional networking?

Options

• Acontroller-based increases network bandwidth usage, while traditional lightens the load on the
• Bcontroller-based inflates software costs, while traditional decreases individual licensing costs
• CController-based reduces network configuration complexity, while traditional increases the
• DController-based provides centralization of key IT functions. While traditional requires distributes
• Econtroller-based allows for fewer network failure, while traditional increases failure rates.

Explanation

Controller-based networking reduces configuration complexity and centralizes management, offering significant advantages over the distributed, device-by-device configuration of traditional networks.

Common mistakes.

• A. Controller-based networking aims to optimize network resource usage, not increase bandwidth usage; traditional networks often have less efficient resource allocation.
• B. While controller-based networking might involve new software or licensing, its overall operational cost benefits, including automation, often lead to total cost of ownership reductions, not necessarily inflated software costs in the long run.
• E. While controller-based networking can improve resilience through faster fault recovery and intelligent traffic management, stating it inherently 'allows for fewer network failure' while traditional 'increases failure rates' is an oversimplification and not a direct comparative benefit in that specific framing.
