SAA-C03 Question #330: Real Exam Question with Answer & Explanation

Question

An ecommerce company is launching a new marketing campaign. The company anticipates the campaign to generate ten times the normal number of daily orders through the company's ecommerce application. The campaign will last 3 days. The ecommerce application architecture is based on Amazon EC2 instances in an Auto Scaling group and an Amazon RDS for MySQL database. The application writes order transactions to an Amazon Elastic File System (Amazon EFS) file system before the application writes orders to the database. During normal operations, the application write operations peak at 5,000 IOPS. A solutions architect needs to ensure that the application can handle the anticipated workload during the marketing campaign. Which solution will meet this requirement?

Options

• AFor the duration of the campaign, increase the provisioned IOPS for the RDS for MySQL
• BFor the duration of the campaign, increase the provisioned IOPS for the RDS for MySQL
• CConvert the database to a Multi-AZ deployment. Set the Amazon EFS throughput mode to Elastic
• DUse AWS Database Migration Service (AWS DMS) to convert the database to RDS for

Explanation

To handle temporary high workloads, Amazon RDS provisioned IOPS can be increased to meet the expected spike in database throughput. Amazon EFS Elastic throughput mode is ideal for workloads with unpredictable or spiky traffic patterns. It automatically scales throughput based on the file system's size and activity, which is more effective than Bursting throughput during high sustained activity like a marketing campaign. Multi-AZ improves availability but does not directly address performance. Migrating to PostgreSQL during a short campaign period introduces unnecessary complexity.
