A.

Create an IAM role, and attach the role to each EC2 instance profile. Use an identity-based policy to grant the new IAM role access to the secret that contains the database credentials.

B.

Create an IAM user, and attach the user to each EC2 instance profile. Use a resource-based policy to grant the new IAM user access to the secret that contains the database credentials.

C.

Create a resource-based policy for the secret that contains the database credentials. Use EC2 Instance Connect to access the secret.

D.

Create an identity-based policy for the secret that contains the database credentials. Grant direct access to the EC2 instances.

Question 22

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

Which solution will meet these requirements?

Options:

A.

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

B.

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

C.

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.

D.

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

B.

Configure the existing S3 bucket to send object creation events to an Amazon Simple Notification Service (Amazon SNS) topic. Configure the Lambda function to run when a new event arrives in the SNS topic.

C.

Configure the existing S3 bucket to send object creation events to an Amazon Simple Queue Service (Amazon SQS) queue. Configure the Lambda function to run when a new event arrives in the SQS queue.

D.

Configure the existing S3 bucket to send object creation events directly to the Lambda function. Configure the Lambda function to handle object creation events and to process the payments.
