SAA-C03 Question #264: Real Exam Question with Answer & Explanation
The correct answer is C: Create an Amazon Simple Queue Service (Amazon SQS) queue to hold the jobs that need to be. Amazon SQS provides durable, decoupled message storage for distributed systems. Using SQS as a job queue enables each EC2 instance to process a message independently. Scaling the Auto Scaling group based on the SQS queue length ensures parallelism and elasticity, aligning compute
Question
A solutions architect is designing the cloud architecture for a new stateless application that will be deployed on AWS. The solutions architect created an Amazon Machine Image (AMI) and launch template for the application. Based on the number of jobs that need to be processed, the processing must run in parallel while adding and removing application Amazon EC2 instances as needed. The application must be loosely coupled. The job items must be durably stored. Which solution will meet these requirements?
Options
- ACreate an Amazon Simple Notification Service (Amazon SNS) topic to send the jobs that need to
- BCreate an Amazon Simple Queue Service (Amazon SQS) queue to hold the jobs that need to be
- CCreate an Amazon Simple Queue Service (Amazon SQS) queue to hold the jobs that need to be
- DCreate an Amazon Simple Notification Service (Amazon SNS) topic to send the jobs that need to
Explanation
Amazon SQS provides durable, decoupled message storage for distributed systems. Using SQS as a job queue enables each EC2 instance to process a message independently. Scaling the Auto Scaling group based on the SQS queue length ensures parallelism and elasticity, aligning compute resources with workload volume.
