I think the key here is about redundancy and recovery, which points towards controller clustering as the best fit. It aligns with adding path diversity too.

Okay, I've got this. The question is asking about the control plane component that needs to be built, and based on the requirements around failover and resiliency, I'm confident that control path reliability is the correct answer.

Alright, let's think this through. The requirements mention improving connectivity and reducing connectivity loss, so I'm thinking controller clustering might be the way to go. That would provide the path diversity and redundancy needed.

Hmm, I'm a bit confused by all the different requirements here. I'm not sure which control plane component is the best fit. Maybe I should review the material on SDN architecture again before attempting this.

This seems straightforward to me. Cloud-native storage orchestration is all about managing storage across multiple cloud providers, not just using a single cloud's storage services. I'll go with B.
