Free AWS Certified Solutions Architect Associate SAA-C03 Practice Question

A company has a workload on Amazon EC2 that exhibits variable usage patterns due to occasional marketing campaigns which lead to unpredictable bursts of traffic. Their current setup uses a fixed number of instances which often results in either over-provisioning or inability to serve peak traffic. What strategy should the Solutions Architect adopt to optimize for cost without sacrificing performance?

  • Predominantly utilize Reserved Instances to ensure capacity and reduce costs.

  • Use a fixed number of On-demand Instances to simplify management.

  • Implement EC2 Auto Scaling with dynamic scaling policies to automatically adjust the number of instances in response to traffic demands.

  • Increase the use of Spot Instances to benefit from cost savings during off-peak times.
