I practiced a similar question, and I think saving the running configuration is important, but it might not be the first step after changing the IP.

I'm not entirely sure, but I feel like rolling back the configuration wouldn't help in this case. It seems more like a commit issue.

I think I remember something about needing to commit changes after modifying the IP address. So, maybe it's A?
