Question 29

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 ' ?

Options:

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.

Create a global secondary index (GSI). Set query attribute to be the partition key of the index

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.

Turn on read capacity auto scaling for the DynamoDB table. Increase the maximum read capacity units (RCUs).

Question 30

A company needs to package and deploy an application that uses AWS Lambda to compress and decompress video clips. The application uses a video codec library that is larger than 250 MB. The application uses the library to compress the videos before storage and to decompress the videos upon retrieval.

Options:

Create one Lambda function. Upload one zip file that contains code to handle video compression and decompression to the function. Include the codec library in the zip file.

Create two Lambda functions. Upload one zip file that contains code to handle video compression to one function. Upload a second zip file that contains code for video decompression to the second function. Include the codec library in both zip files.

Create two Lambda functions. Build one container image that contains code to handle video compression and a second image that contains video decompression code. Add the codec library to both images. Upload the images to Amazon ECR. Use the containers to create the Lambda functions.
