Question #864 / 1019

A company operates its application using an Amazon Aurora DB cluster. During periods of high traffic, when numerous users are performing read operations, the database experiences slower write query performance. The company aims to enhance scalability cost-effectively to handle peak loads without affecting write operations.

B

Deploy an Amazon ElastiCache cluster in front of the Aurora DB cluster. Configure the application to use ElastiCache for read queries and direct write operations to the Aurora cluster.

C

Add an Aurora read replica to the existing cluster. Configure the application to route read queries to the read replica endpoint and write operations to the primary cluster endpoint.

D

Migrate the database to an Amazon Neptune cluster. Update the application to use Neptune for read queries and retain Aurora for write operations.

Question #150 / 1019

A

Purchase a Compute Savings Plan for the streaming application instances. Use On-Demand Instances for the data processing application.

B

Purchase a Compute Savings Plan for the streaming application instances. Use Spot Instances for the data processing application.

C

Use Spot Instances for both the streaming and data processing applications. Deploy AWS Service Catalog to provision discounted resources.

D

Use On-Demand Instances for the streaming application. Use Spot Instances for the data processing application. Deploy AWS Service Catalog to provision discounted resources.
