1. True or False: Kinesis streams are appropriate for persistent storage of your streaming data.
2. True or False: With both local secondary indexes and global secondary indexes, you can define read capacity units and write capacity units on the index itself — so that you don't have to consume them from the base table.
3. Which of the following must be defined when you create a table? (Choose 4)
4. Which of the following attribute data types can be table or item keys? (Choose 3)
5. Which of the following statements is true?
6. In terms of data write-rate for data input, what is the capacity of a shard in a Kinesis stream?
7. In terms of data read-rate for data output, what is the capacity of a shard in a Kinesis stream?
8. A producer application has been designed to write thousands of events per second to Kinesis Streams by integrating the Kinesis Producer library into the application. The application takes data from logs on EC2 instances and ingests the data into Streams records. Which of the following solutions did the developer use to improve throughput when implementing the KPL with the application?
9. True or False: You can add a local secondary index to a DynamoDB table after it has been created.
10. What are the max deliverables from one Dynamo DB Partition.
11. Your company has a number of consumer applications to get records from various Kinesis Streams for different use cases. For each consumer application there is a separate DynamoDB table that maintains application state. Out of the many consumer applications, one application is experiencing provisioned throughput exception errors with its particular DynamoDB table. Why is this happening? (Choose 2)
12. The Kinesis Connector Library allows you to emit data from a stream to various AWS services. Which of the following services can receive data emitted from such a stream? (Choose 4)
13. You have an application based on the Amazon Kinesis Streams API, and you are not using the Kinesis Produce Library as part of your application. While you won't be taking advantage of all the benefits of the KPL in your application, you still need to ensure that you add data to a stream efficiently. Which API operation allows you to do this?
14. Which operation/feature or service would you use to locate all items in a table with a particular sort key value? (Choose 2)
