Question 17)
A hospital is migrating from another cloud provider to AWS and wants to modernize as they migrate. The hospital has containerized applications that run on tablets. During spikes caused by increases in patient visits, the communications from the applications to the central database occasionally fail. As a result, the hospital currently has the applications try to write to the central database once. If that write fails, the application writes to a dedicated application PostgreSQL database run by the hospital IT team on premises. Each of the PostgreSQL databases then sends batch information to the central database.

Question 18)
A company uses Amazon EC2 instances in a test environment. The company has optimized the instances for their current workload. The company uses the instances only during business hours. The company uses Compute Savings Plans and Spot Instances. The company must retain control over the compute resources. A solutions architect must recommend a solution to reduce costs associated with the EC2 instances in the test environment. Which solution will meet these requirements?

• Use AWS Compute Optimizer and change the instance type or size based on the recommendations.
• Create a time-based Amazon CloudWatch alarm action to start and stop the instances.
• Use Reserved Instances in addition to the Compute Savings Plan and Spot Instances.
• Switch from EC2 instances to AWS Lambda functions to optimize the runtime environment.

Question 19)
