I think is B. A doesnt make any sense. C narrows the traffic type to HTTP and HTTPS. This is not the only type of traffic than an application can have. D Doesn't make any sense.

D makes sense to me, DevNet Cisco course specifically calls out how important it is to test a small number of users on new code/services and then slowly move more and more to the new service. A load balancer would be perfect for that.

B = Load Balancing D = AutoScalling + Load Balancing Is "Bring up new compute units" load balancers role? Maybe the "modern application deployments" means this. It is a very tricky question.

Very tricky question, to me D seems the most correct as you don't put in production things that are not tested, still I understand those who prefer B as there are situations (like containers for instance) which you don't really have to test anything anymore... maybe the "modern application deployments" means just that... I don't know.
