The correct answer is A. Efficient implementation by connecting forwarding devices to multiple controller. B. Controller deployment planning is more dependent on the topology than on network size. Connecting forwarding devices to multiple controllers improves resilience by avoiding a single point of failure and allows load distribution for scalability. Controller deployment depends more on the topology (e.g., latency, clustering, distribution of devices) than simply the…
Question
SDN controllers need to sustain healthy operation under the pressure of different objectives from the applications they host. High availability can be achieved through improved southbound APIs and controller placement heuristics and formal models. Which two implementation strategy help to maximize resilience and scalability? (Choose two.)
Options
- AEfficient implementation by connecting forwarding devices to multiple controller.
- BController deployment planning is more dependent on the topology than on network size.
- CController deployment planning is more dependent on network size than on the topology.
- DCost-effective implementation by connecting forwarding devices to single controller.
- EController deployment planning is more dependent on network type than application need.

Explanation
Connecting forwarding devices to multiple controllers improves resilience by avoiding a single point of failure and allows load distribution for scalability. Controller deployment depends more on the topology (e.g., latency, clustering, distribution of devices) than simply the network size, ensuring effective placement for high availability.
