300-435 Question 150
Single answerAn enterprise network engineer wants to simplify the management of their network by using software-defined networking (SDN) instead of a traditional network approach. Which of the following characteristics of SDN provides a significant advantage over traditional networks in this scenario?
- A
Centralized control plane decoupled from the data plane
- B
Manual device-by-device configuration for policy implementation
- C
Static network topology with limited programmability
- D
Integration with APIs for automation and orchestration
Show answer and explanation
Correct answer: A
Explanation
SDN provides significant advantages over traditional networks by decoupling the control plane from the data plane, enabling centralized management and dynamic programmability. This eliminates the need for manual, device-specific configurations and static network designs, which are hallmarks of traditional networks. While API integration is an important feature of SDN, it is the centralized control plane that fundamentally simplifies network management.
- A. Correct.
Centralized control plane decoupled from the data plane is a core characteristic of SDN, allowing simplified and centralized management of policies and configurations, which is a significant advantage over traditional networks.
- B. Incorrect.
Manual device-by-device configuration is a characteristic of traditional networks and is a disadvantage when compared to SDN's centralized management.
- C. Incorrect.
Static network topology with limited programmability is another limitation of traditional networks, which SDN overcomes with its dynamic and programmable nature.
- D. Incorrect.
Integration with APIs for automation and orchestration is an advantage of SDN, but this is a feature enabled by the centralized control plane, which is the main characteristic that simplifies management.
