Topic 1 Question 366
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?
Adjust the Auto Scaling group to scale faster when a high number of messages is in the queue.
Use the Amazon Simple Notification Service (Amazon SNS) fanout feature with Amazon SQS to send the notifications in parallel to all the C2 instances
Add an Amazon DynamoDB stream to accelerate the message processing
Create a queue for alarm notifications and a queue for information notifications. Update the application to collect messages from the alarm notifications queue first.

You need to process messages with different priorities
👍 3jas26says2023/07/21 Option D is the correct solution to prioritize alarm notifications over information notifications. By creating separate queues for alarm notifications and information notifications, you can ensure that the messages are kept separate and can be processed independently. This approach allows you to prioritize the alarm notifications by having the application collect messages from the alarm notifications queue first.
