2. B. Use a target tracking policy to dynamically scale the Auto Scaling group
3. C. Use an AWS Lambda function to update the desired Auto Scaling group capacity
4. D. Use scheduled scaling actions to scale up and scale down the Auto Scaling group

A solutions architect is designing an application for a two-step order process The first step is synchronous and must return to the user with little latency The second step takes longer, so it will be implemented in a separate component Orders must be processed exactly once and in the order in which they are received
How should the solutions architect integrate these components?

1. A. Use Amazon SQS FIFO queues.
2. B. Use an AWS Lambda function along with Amazon SQS standard queues
3. C. Create an SNS topic and subscribe an Amazon SQS FIFO queue to that topic
4. D. Create an SNS topic and subscribe an Amazon SQS Standard queue to that topic.

Correct Answer: C

A solutions architect is designing a new service behind Amazon API Gateway The request patterns for the service will be unpredictable and can change suddenly from 0 requests to over 500 per second The total size of the data that needs to be persisted in a backend database is currently less than 1 GB with unpredictable future growth Data can be queried using simple key-value requests
Which combination of AWS services would meet these requirements'? (Select TWO )

1. A. AWS Fargate
2. B. AWS Lambda
3. C. Amazon DynamoDB
4. D. Amazon EC2 Auto Scaling
5. E. MySQL-compatible Amazon Aurora
