in general vcpu/memory(GiB) ratios for: general purpose: 1/2 memory optimized: 1/4 compute optimized: 1/2 example: cheapest non burstable GP: m6g.xlarge 4vpcu, 16GiB, price: 0.154 cheapest memory optimized: r6g.large 2vcpi, 16GiB, price: 0.1008 anticipated outcome: 80% cpu, 80% mem, 35% cost savings

Selected Answer: B

B. CPU utilisation is rather low for using an xlarge instance, so a memory optimized large instance is a cheaper option that should meet the workload requirements.

For me its C. You can reduce teh cost using a spot instance. Here more about spot instance https://www.amazonaws.cn/en/ec2/spot-instances/faqs/

Questions states - reduce the cost of the service without negatively affecting performance. Using a Spot Instance may affect performance, if it terminates with only a 2 min warning. The stats state the load is Memory intensive, so B looks to be most suitable.
