True or False: Kinesis streams are appropriate for persistent storage of your streaming data. False True 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. False True 3. Which of the following must be defined when you create a table? (Choose 4) The table capacity, number of GB. The RCU (Read Capacity Units) The WCU (Write Capacity Units) The DCU (Delete/Update Capacity Units) Partition Key The Table Name 4. Which of the following attribute data types can be table or item keys? (Choose 3) Number Blob Map Binary String 5. Which of the following statements is true? A shard supports up to 1000 transactions per second for reads, and 5 transactions per second for writes. A shard supports up to 5 transactions per second for reads, and 1000 records per second for writes. A shard supports up to 5 transactions per second for reads, and 10 records per second for writes. 6. In terms of data write-rate for data input, what is the capacity of a shard in a Kinesis stream? 4 MB/s 1 MB/s 2 MB/s 7. In terms of data read-rate for data output, what is the capacity of a shard in a Kinesis stream? 1 MB/s 2 MB/s 4 MB/s 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? Aggregation Re-Aggregation De-Aggregation 9. True or False: You can add a local secondary index to a DynamoDB table after it has been created. False True 10. What are the max deliverables from one Dynamo DB Partition. 4,000 WCU, 1,000RCU, 10GB Data volume No maximums 1,000 WCU, 3,000RCU, 10GB Data volume 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) The application is checkpointing too frequently. The application is not checkpointing enough. The stream has too many shards. The stream does not have enough shards. 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) RDS S3 Redshift Elasticsearch Lambda DynamoDB 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? PutItems PutItem PutRecords 14. Which operation/feature or service would you use to locate all items in a table with a particular sort key value? (Choose 2) GetItem Scan against a table, with filters Query Query with a local secondary index Query with a global secondary index Please fill in the comment box below.
