Software-Defined Networking (SDN) centralizes network control by decoupling the control plane from the data plane, enabling:

Centralized Management: Administrators can control the entire network from a single point.

Dynamic Policy Enforcement: Security policies can be applied uniformly across the network.

Real-Time Adjustments: Quickly adapt to emerging threats by reconfiguring policies from the central controller.

Enhanced Visibility: Consolidated monitoring through centralized control improves security posture.

Incorrect Options:

A . Simplifies network topology: This is a secondary benefit, not the primary security advantage.

B . Greater scalability and flexibility: While true, it is not directly related to security.

D . Improves monitoring and alerting: SDN primarily focuses on control, not monitoring.

Exact Extract from CCOA Official Review Manual, 1st Edition:

Refer to Chapter 5, Section 'Software-Defined Networks,' Subsection 'Security Benefits' - SDN's centralized control model significantly enhances network security management.
