A company runs an application on AWS The application stores data in an Amazon DynamoDB table Some queries are taking a long time to run These slow queries involve an attribute that is not the table's partition key or sort key The amount of data that the application stores in the DynamoDB table is expected to increase significantly. A developer must increase the performance of the queries.
Which solution will meet these requirements'?

• A.Increase the page size for each request by setting the Limit parameter to be higher than the default value Configure the application to retry any request that exceeds the provisioned throughput.
• B.Create a global secondary index (GSI). Set query attribute to be the partition key of the index
• C.Perform a parallel scan operation by issuing individual scan requests in the parameters specify the segment for the scan requests and the total number of segments for the parallel scan.
• D.Turn on read capacity auto scaling for the DynamoDB table. Increase the maximum read capacity units (RCUs).

A company developed an API application on AWS by using Amazon CloudFront. Amazon API Gateway, and AWS Lambd a. The API has a minimum of four requests every second A developer notices that many API users run the same query by using the POST method. The developer wants to cache the POST request to optimize the API resources.
Which solution will meet these requirements'?

• A.Configure the CloudFront cache Update the application to return cached content based upon the default request headers.
• B.Override the cache method in me selected stage of API Gateway Select the POST method.
• C.Save the latest request response in Lambda /tmp directory Update the Lambda function to check the /tmp directory
• D.Save the latest request m AWS Systems Manager Parameter Store Modify the Lambda function to take the latest request response from Parameter Store
