Actual exam question for Amazon's DBS-C01 exam

Question #: 37
Topic #: 6

A database specialist needs to review and optimize an Amazon DynamoDB table that is experiencing performance issues. A thorough investigation by the database specialist reveals that the partition key is causing hot partitions, so a new partition key is created. The database specialist must effectively apply this new partition key to all existing and new data.

How can this solution be implemented?

AUse Amazon EMR to export the data from the current DynamoDB table to Amazon S3. Then use Amazon EMR again to import the data from Amazon S3 into a new DynamoDB table with the new partition key.

BUse AWS DMS to copy the data from the current DynamoDB table to Amazon S3. Then import the DynamoDB table to create a new DynamoDB table with the new partition key.

CUse the AWS CLI to update the DynamoDB table and modify the partition key.

DUse the AWS CLI to back up the DynamoDB table. Then use the restore-table-from-backup command and modify the partition key.
