Exam CISSP topic 1 question 121 discussion

The keyword is "security benefit" A. Centralized network provisioning - its SDN feature/ capability B. Reduced network latency when scaled - latency relates to performance C. Centralized network administrative control - interestingly, this option is a strength and weakness for SDN. Although you can provide defence of depth controls on the SDN controller but compromising the admin account can initiate various types of attacks on SDN. but this option seems right compared to others D. Reduced hardware footprint and cost - this relates to business cost and deployment

Could easily be D as this is also correct.

security related benefit: Centralized administration

option C: Centralized network administrative control, is a security-related benefit that software-defined networking (SDN) provides.

Best answer is C: Security is also another benefit that enterprises notice with an SDN. This means you can extend your defense capabilities from simply blocking specific attacks to making proactive changes to adjust to new threats. The SDN controller can push global security policy updates out centrally across the network, and a virtualized switch can filter packets at the network edge and redirect suspicious traffic to other security devices for further analysis. Provisioning is part of administrative control.

I mean "C" Centralizing the network admin control will come with a single point of failure, which is not good for security. But I am going with "C" still..... unless someone has a batter explanation.
