Topic 1 Question 469
Users of a company's internal web application recently experienced application performance issues for a brief period. The application includes frontend web servers that run in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The application also includes a backend Amazon Aurora PostgreSQL DB cluster that includes one DB instance.
A SysOps administrator determines that the source of the performance issues was high utilization of the DB cluster. The single writer instance experienced more than 90% utilization for 11 minutes. The cause of the high utilization was an automated report that is scheduled to run one time each week.
What should the SysOps administrator do to ensure that users do not experience performance issues each week when the report runs?
Increase the size of the DB instance. Monitor the performance during the next scheduled run of the report.
Add a reader instance. Change the database connection string of the report application to use the newly created reader instance.
Add another writer instance. Change the database connection string of the report application to use the newly created writer instance.
Configure auto scaling for the DB cluster. Set the minimum capacity units, maximum capacity units, and target utilization.

Adding a reader instance will offload read-heavy operations (such as generating reports) from the writer instance, which is responsible for handling write transactions. This will prevent the report from overloading the writer instance during its execution. Changing the connection string of the report application to use the reader instance ensures that the report runs against the read replica, leaving the primary writer instance available for regular transactional operations without causing high utilization issues.

It def. can't be B since the issue has with the Writer operations and not with the Read one. Option A looks to be a bit more relevant for this scenario..
