Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 248 discussion

D. Route incoming requests to Amazon Simple Queue Service (Amazon SQS). Configure an EC2 Auto Scaling group based on queue size. Update the software to read from the queue. By routing incoming requests to Amazon SQS, the company can decouple the job requests from the processing instances. This allows them to scale the number of instances based on the size of the queue, providing more resources when needed. Additionally, using an Auto Scaling group based on the queue size will automatically scale the number of instances up or down depending on the workload. Updating the software to read from the queue will allow it to process the job requests in a more efficient manner, improving the performance of the system.

D is correct

The based on the queue size doesn't seem a perfect approach though

D: Because this whole exam seems to be selling more and more SQS solutions...

D. Route incoming requests to Amazon Simple Queue Service (Amazon SQS). Configure an EC2 Auto Scaling group based on queue size. Update the software to read from the queue.

I would vote A if it was ALB targeting an EC2 auto scaling group. I would vote D if the auto scaling group was based on CPU utilization rather than queue size. So I think both answers are wrong but D is okay enough.

A. Creating a copy of the instance and placing all instances behind an ALB does not address the high CPU utilization issue or provide scalability based on user load. B. Creating an S3 VPC endpoint for S3 and updating the software to reference the endpoint improves network performance but does not address the high CPU utilization or provide scalability based on user load. C. Stopping the EC2 instances and modifying the instance type to one with a more powerful CPU and more memory may improve performance, but it does not address scalability based on user load. D. Routing incoming requests to SQS, configuring an EC2 ASG based on queue size, and updating the software to read from the queue improves system performance and provides scalability based on user load. Therefore, option D is the correct choice as it addresses the high CPU utilization, improves system performance, and enables scalability based on user load.

Autoscaling Group and SQS solves the problem. SQS - Decouples the process ASG - Autoscales the EC2 instances based on usage

its definitely A

D is correct. Decouple the process. autoscale the EC2 based on query size. best choice

I think it's A " A. Create a copy of the instance. Place all instances behind an Application Load Balancer.
