Topic 1 Question 459
A company is preparing for a marketing campaign that will increase traffic to a new web application. The application uses Amazon API Gateway and AWS Lambda for the application logic. The application stores relevant user data in an Amazon Aurora MySQL DB cluster that has one Aurora Replica. Database queries for the application are 5% write and 95% read.
What should a SysOps administrator do to scale the database when traffic increases?
Configure Aurora Auto Scaling to add or remove Aurora Replicas in the cluster based on the average CPU utilization of the Aurora Replicas.
Configure Aurora Auto Scaling to increase or decrease the size of the Aurora Replicas based on the average CPU utilization of the Aurora Replicas.
Configure AWS Auto Scaling to monitor the Aurora cluster. Configure AWS Auto Scaling to add or remove Aurora Replicas in the cluster based on the average CPU utilization of the primary instance.
Configure AWS Auto Scaling to monitor the Aurora cluster. Configure AWS Auto Scaling to add or remove Aurora Replicas in the cluster based on the average CPU utilization of the existing Aurora Replica.

- 正解だと思う選択肢: A
Answer B is incorrect because Aurora replicas always have the same DB instance size/class as the one used by the primary instance. Answer C is incorrect because in the Aurora Auto Scaling policy, you cannot select as metric the average CPU utilization of the primary instance (you must choose a predefined or custom metric that consider the status of ALL THE READ REPLICAS). Answer D is incorrect because in the Aurora Auto Scaling policy, you cannot select the average CPU utilization OF THE EXISTING Aurora Replica (you CANNOT CHOOSE a predefined or custom metric that consider only A SUBSET OF READ REPLICAS). Answer A is correct: you just need to define and apply an Aurora Auto Scaling policy, choosing Average CPU utilization of Aurora Replicas as the target metric.
