Selected Answer: A

C can be eliminated by the cost-effective request. A and B are similar, one automatically and one manually. The automatic solution A is preferred. D scaling up and down based on the demand may be against the better performance request. As the load is predictable, scheduling auto-scaling is preferred.

A. It is SAA question. In the given options most cost effective to keep 10 instance active and 10 add at office hours. The deference between A and B is whether manually add or automatically through ASG. I would prefer through ASG scheduled scaling
