A company is building an application to track athlete performance using an Amazon DynamoDB table. Each item in the table is identified by a partition key (user_id) and a sort key (sport_name). The table design is shown below:

(Note: Not all table attributes are shown)
A Developer is asked to write a leaderboard application to display the top performers (user_id) based on the score for each sport_name.
What process will allow the Developer to extract results MOST efficiently from the DynamoDB table?

• A.Use a DynamoDB query operation with the key attributes of user_id and sport_name and order the results based on the score attribute.
• B.Create a global secondary index with a partition key of sport_name and a sort key of score, and get the results
• C.Use a DynamoDB scan operation to retrieve scores and user_id based on sport_name, and order the results based on the score attribute.
• D.Create a local secondary index with a primary key of sport_name and a sort key of score and get the results based on the score attribute.

An application is running on an EC2 instance. The Developer wants to store an application metric in Amazon CloudWatch.
What is the best practice for implementing this requirement?

• A.Publish the metric data to an Amazon Kinesis Stream using a PutRecord API call. Subscribe a Lambda function that publishes data to CloudWatch.
• B.Use the CloudWatch PutMetricData API call to submit a custom metric to CloudWatch. Launch the EC2 instance with the required IAM role to enable the API call.
• C.Use the PUT Object API call to send data to an S3 bucket. Use an event notification to invoke a Lambda function to publish data to CloudWatch.
• D.Use the CloudWatch PutMetricData API call to submit a custom metric to CloudWatch. Provide the required credentials to enable the API call.
