AnswerD For Aurora we have 2 storage type/options: A - Standard B -- I/O-Optimized hence answers B and C options are incorrect. Because customer inform us that there will be a big amount of traffic for their application I would go with I/O-Optimized. Maybe we are giving more $$ per GB-month but we are not paing for I/O operations/request. https://aws.amazon.com/rds/aurora/pricing/ In general question is not precise and it is hard to say which option will be more beneficial (cost effective)

In my opinion, when the company "wants to optimize the storage performance of the cluster AS the load on the application increases" they mean that they EXPECT that the load increases somewhere in the future. If so, what's the point of paying more for the I/O optimised storage configuration from the very beginning? You can switch to this more expensive configuration AS the load increased, saving money before this increment occurs

Selected Answer: C

The traffic load is not defined well enough to decide which storage type to use. General Purpose (SSD) storage suits many workloads, including small to medium-sized databases and it is cost-effective. Provisioned IOPS (PIOPS) storage is the highest-performing option available for RDS instances. With Provisioned IOPS storage, you can provision a specific amount of IOPS (input/output operations per second) based on your application’s needs. But here we don't know the amount of requests. So since the question is asking for cost-effective I'll go with C
