An application uses an Amazon DynamoDB table to manage user profiles. A UserID attribute is the primary key of the table. The table also includes columns named Username, EmailAddress, RegistrationDate, Location, and Status.
The application needs to display a list of users from a specific location who registered after a specific date. Queries on the table must be optimized for efficiency.
Which solution will meet these requirements?
A company is building a web application on AWS. When a customer sends a request, the application will generate reports and then make the reports available to the customer within one hour. Reports should be accessible to the customer for 8 hours. Some reports are larger than 1 MB. Each report is unique to the customer. The application should delete all reports that are older than 2 days.
Which solution will meet these requirements with the LEAST operational overhead?
A company is developing a weather forecast application that displays forecasts for towns and cities in a single country for a specified date range. The application stores weather data in an Amazon DynamoDB table named Forecasts. The Forecasts table has attributes named CityId, Temperature, and ForecastDate. The company expects the application to be read-heavy and that the vast majority of reads will target the current day’s forecast for one of a small number of very large cities. The company needs to design a partition key configuration that will yield the most even distribution of read requests for the application ' s expected use case. Which solution will meet these requirements?
A company has an application that is deployed on AWS Elastic Beanstalk. The application generates user-specific PDFs and stores the PDFs in an Amazon S3 bucket. The application then uses Amazon Simple Email Service (Amazon SES) to send the PDFs by email to subscribers.
Users no longer access the PDFs 90 days after the PDFs are generated. The S3 bucket is not versioned and contains many obsolete PDFs.
A developer must reduce the number of files in the S3 bucket by removing PDFs that are older than 90 days.
Which solution will meet this requirement with the LEAST development effort?
