A key benefit ofSoftware-Defined Networking (SDN)is that it allows networks to bedynamically configured and managed through software. SDN separates the control plane from the data plane, enabling centralized management and programmable network configurations, which improves flexibility and scalability in cloud environments.
From theCCSK v5.0 Study Guide, Domain 9 (Network Security), Section 9.3:
"Software-Defined Networking (SDN) enables dynamic configuration and management of networks through software, decoupling the control plane from the data plane. This allows organizations to programmatically adjust network policies and traffic flows, improving agility and scalability in cloud environments." Option C (SDN allows networks to be dynamically configured and managed through software) is the correct answer.
Option A (Hardware-based solution) is incorrect because SDN is software-based.
Option B (Eliminates physical devices) is incorrect because SDN still relies on physical infrastructure.
Option D (Focused on firewalls) is incorrect because SDN's primary benefit is flexibility, not firewalls.
