Free Cisco CCNA 200-301 Actual Exam Questions - Question 8 Discussion

Makes sense to pick B since SDN moves control out of devices for central management. B

It’s B because SDN’s main goal is to move the control plane out of individual devices and manage it centrally, which simplifies network configuration and policy enforcement.

Probably B since SDN’s core is centralizing control, not data or apps.

Option B stands out since SDN’s main idea is to centralize control decisions, separating them from data forwarding. That’s what makes the control plane the core focus here.

Maybe D but it feels less likely since services are more like added functions on top of the basic layers. The key SDN shift is about separating and centralizing control over the network behavior, which points more to B. So if you rule out services and data (which just forwards packets), control is the main focus for centralization, not application either since apps run on top of the control layer.

B The control plane is what SDN centralizes to simplify network management and make policies easier to enforce. Data and application planes still stay distributed.

B imo, since the whole point of SDN is to have a centralized control point managing network traffic, rather than distributing control across devices like in traditional setups.

It’s kind of a tricky one but B makes the most sense since SDN focuses on centralizing the control plane to manage the network.
