First Question: An application is processing data from an Amazon Kinesis Data Stream. The Data Stream has 12 shards with one KCL worker each. The volume of data has increased, and an additional 6 shards have been added to the stream. What is the MAXIMUM number of EC1 instance required for optimum performance? 1. 18 2. 9 3. 36 4. 12 The correct answer is 1. Explanation: Resharding enables you to increase or decrease the number of shards in a stream in order to adapt to changes in the rate of data flowing through the stream. Resharding is typically performed by an administrative application that monitors shard data-handling metrics. Although the KCL itself doesn't initiate resharding operations, it is designed to adapt to changes in the number of shards that result from resharding. "9" is incorrect as each shard is processed by exactly one KCL worker so there would be too few workers. "36" is incorrect as the optimum ratio is 1:1 between KCL workers and shards. "12" is incorrect as the optimum ratio is 1:1 between KCL workers and shards. Second Question: A Developer needs to configure an Elastic Load Balancer that is deployed through AWS Elastic Beanstalk. Where should the Developer place the load-balancer.config file in the application source bundle? 1. In the root of the source code 2. In the bin folder 3. In the load-balancer.config.root 4. In the .ebextensions folder The correct answer is 4. Explanation: You can add AWS Elastic Beanstalk configuration files (.ebextensions) to your web application's source code to configure your environment and customize the AWS resources that it contains. Configuration files are YAML- or JSON-formatted documents with a .config file extension that you place in a folder named .ebextensions and deploy in your application source bundle. "In the root of the source code" is incorrect. You need to place .config files in the .ebextensions folder. "In the bin folder" is incorrect. You need to place .config files in the .ebextensions folder. "In the load-balancer.config.root" is incorrect. You need to place .config files in the .ebextensions folder. _______________________ 🎯 Keen to get AWS certified and launch your Cloud career?
