Discuss Isaca CCOA Exam Topic 5 Question 21

Which of the following is the PRIMARY benefit of using software-defined networking for network security?

AIt simplifies network topology and reduces complexity.

BIt provides greater scalability and flexibility for network devices.

CIt allows for centralized security management and control.

DIt Improves security monitoring and alerting capabilities.

Suggested Answer: C

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.

Wait, can SDN really improve security that much?

Shawnna 3 months ago

I think B is just as important for flexibility.

Maxima 3 months ago

Definitely C! Centralized control is key for security.

Viola 3 months ago

Honestly, I’m torn between A and C. Simplifying the network sounds good, but centralized control seems like a bigger deal for security.

Jolanda 3 months ago

I’m leaning towards option C, but I also recall something about improved monitoring capabilities being really important.

Yolando 3 months ago

I remember a practice question that emphasized scalability and flexibility, but I feel like security management is more crucial.
