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.

Maybe we could rig up a system where the alarm notifications trigger a loud siren and flashing lights to really get the EC2 instances' attention.

Great suggestion! With these solutions in place, the alarm notifications will be prioritized effectively.

That sounds like a good idea. We can also set up a dead-letter queue for the information notifications to ensure they are not lost.

We could use Amazon CloudWatch alarms to monitor the SQS queue and trigger a Lambda function to process the alarm notifications 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 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.
