Amazon Exam SOA-C02 Topic 8 Question 83 Discussion

Actual exam question for Amazon's SOA-C02 exam

Question #: 83
Topic #: 8

A company has an application that collects notifications from thousands of alarm systems. The notifications include alarm notifications and information notifications. The information notifications include the system arming processes, disarming processes, and sensor status.

All notifications are kept as messages in an Amazon Simple Queue Service (Amazon SQS) queue. Amazon EC2 instances that are in an Auto Scaling group process the messages. A SysOps administrator needs to implement a solution that prioritizes alarm notifications over information notifications.

Which solution will meet these requirements?

AAdjust the Auto Scaling group to scale faster when a high number of messages is in the queue.

BUse the Amazon Simple Notification Service (Amazon SNS) fanout feature with Amazon SQS to send the notifications in parallel to all the EC2 instances.

CAdd an Amazon DynamoDB stream to accelerate the message processing.

DCreate a queue for alarm notifications and a queue for information notifications. Update the application to collect messages from the alarm notifications queue first.

Adding a DynamoDB stream? That's like trying to put out a fire with a squirt gun. Definitely not the right solution here.

Using Amazon SNS fanout could work, but it might be overkill for this use case. Plus, it doesn't really address the need to prioritize the alarm notifications.

I prefer option B, using SNS fanout feature seems efficient.

I agree with Aliza, separating the queues makes sense.

I'm not sure why we need to scale the Auto Scaling group faster when we can just prioritize the alarm notifications. That seems like an unnecessary complication.

Option D seems like the most straightforward and effective solution to prioritize alarm notifications. Separating the queues makes it easier to handle the different types of notifications.
