An architect designs a multi-controller network architecture with these requirements:* Achieve fast failover to control traffic when controllers fail.* Yield a short distance and high resiliency in the connection between the switches and the controller.* Reduce connectivity loss and enable smart recovery to improve the SDN survivability.* Improve connectivity by adding path diversity and capacity awareness for controllers.Which control plane component of the multi-controller must be built to meet the requirements?

A. control node reliability B. control path reliability C. controller state consistency D. controller clustering
