Question 29

A media company runs an application on multiple Amazon EC2 instances that requires high storage input/output operations per second (IOPS).

To achieve the necessary performance, a solutions architect wants to stripe multiple Amazon EBS volumes together and attach the volumes to EC2 instances. The solutions architect wants to receive a notification when IOPS are over-provisioned.

Which solution will meet these requirements?

Options:

Configure auto scaling for the EBS volumes to automatically increase or decrease IOPS based on the EC2 instance CPU utilization metric.

Deploy the application on an EC2 instance type that supports the highest possible IOPS.

Create a custom AWS Config rule to monitor the provisioned IOPS for the EBS volumes that are attached to the EC2 instances and to send notifications.

Adjust the IOPS of each EBS volume daily based on Amazon CloudWatch metrics for IOPS utilization.

Options:

Configure AWS CloudTrail trails to log Amazon S3 API calls. Use AWS AppSync to process the files.

Configure a new object created S3 event notification within the bucket to invoke an AWS Lambda function to process the files.

Configure Amazon Kinesis Data Streams to deliver the files to the S3 bucket. Invoke an AWS Lambda function to process the files.
