A developer runs an application that displays scores for sports games on Amazon EC2 instances. The application uses a Redis client to retrieve the scores from an Amazon ElastiCache (Redis OSS) cluster. The developer observes increased latency during operations on the cache because of connection failures to the cluster. The developer needs to resolve the latency issues. Which solution will meet this requirement?
A company has migrated an application to Amazon EC2 instances. Automatic scaling is working well for the application user interface. However, the process to deliver shipping requests to the company's warehouse staff is encountering issues. Duplicate shipping requests are arriving, and some requests are lost or arrive out of order. The company must avoid duplicate shipping requests and must process the requests in the order that the requests arrive. Requests are never more than 250 KB in size and take 5-10 minutes to process. A developer needs to rearchitect the application to improve the reliability of the delivery and processing of the requests. What should the developer do to meet these requirements?
A developer is creating a web application for a school that stores data in Amazon DynamoDB. The ExamScores table has the following attributes: student_id, subject_name, and top_score. Each item in the ExamScores table is identified with student_id as the partition key and subject_name as the sort key. The web application needs to display the student _id for the top scores for each school subject. The developer needs to increase the speed of the queries to retrieve the student_id for the top scorer for each school subject. Which solution will meet these requirements?
A developer creates a static website for their department. The developer deploys the static assets for the website to an Amazon S3 bucket and serves the assets with Amazon CloudFront. The developer uses origin access control (OAC) on the CloudFront distribution to access the S3 bucket. The developer notices users can access the root URL and specific pages but cannot access directories without specifying a file name. For example, /products/index.html works, but /products/ returns an error. The developer needs to enable accessing directories without specifying a file name without exposing the S3 bucket publicly. Which solution will meet these requirements?
A company has an application that runs as a series of AWS Lambda functions. Each Lambda function receives data from an Amazon Simple Notification Service (Amazon SNS) topic and writes the data to an Amazon Aurora DB instance. To comply with an information security policy, the company must ensure that the Lambda functions all use a single securely encrypted database connection string to access Aurora. Which solution will meet these requirements?
