A company uses Amazon DynamoDB for managing and tracking orders. The DynamoDB table is partitioned based on the order date. The company receives a huge increase in orders during a sales event, causing DynamoDB writes to throttle, and the consumed throughput is far below the provisioned throughput.
According to AWS best practices, how can this issue be resolved with MINIMAL costs?

• A.Create a new DynamoDB table for every order date.
• B.Increase the read and write capacity units of the DynamoDB table.
• C.Add a random number suffix to the partition key values.
• D.Add a global secondary index to the DynamoDB table.

A Developer is migrating an on-premises application to AWS. The application currently takes user uploads and saves them to a local directory on the server. All uploads must be saved and made immediately available to all instances in an Auto scaling group.
Which approach will meet these requirements?

• A.Use instance storage and share it between instances launched from the same Amazon machine image (AMI).
• B.Use Amazon EBS and configure the application AMI to use a snapshot of the same EBS instance on boot.
• C.Use Amazon S3 and rearchitect the application so all uploads are placed in S3.
• D.Use Amazon EBS and file synchronization software to achieve eventual consistency among the auto scaling group.

A deployment package uses the AWS CLI to copy files into any S3 bucket in the account, using access keys stored in environment variables. The package is running on EC2 instances, and the instances have been modified to run with an assumed IAM role and a more restrictive policy that allows access to only one bucket.
After the change, the Developer logs into the host and still has the ability to write into all of the S3 buckets in that account.
What is the MOST likely cause of this situation?

• A.An IAM inline policy is being used on the IAM role
• B.An IAM managed policy is being used on the IAM role
• C.The AWS CLI is corrupt and needs to be reinstalled
• D.The AWS credential provider looks for instance profile credentials last
