Topic 1 Question 490
A gaming company uses Amazon DynamoDB to store user information such as geographic location, player data, and leaderboards. The company needs to configure continuous backups to an Amazon S3 bucket with a minimal amount of coding. The backups must not affect availability of the application and must not affect the read capacity units (RCUs) that are defined for the table.
Which solution meets these requirements?
Use an Amazon EMR cluster. Create an Apache Hive job to back up the data to Amazon S3.
Export the data directly from DynamoDB to Amazon S3 with continuous backups. Turn on point-in-time recovery for the table.
Configure Amazon DynamoDB Streams. Create an AWS Lambda function to consume the stream and export the data to an Amazon S3 bucket.
Create an AWS Lambda function to export the data from the database tables to Amazon S3 on a regular basis. Turn on point-in-time recovery for the table.

- 正解だと思う選択肢: B
Continuous backups is a native feature of DynamoDB, it works at any scale without having to manage servers or clusters and allows you to export data across AWS Regions and accounts to any point-in-time in the last 35 days at a per-second granularity. Plus, it doesn’t affect the read capacity or the availability of your production tables.

Continuous Backups: DynamoDB provides a feature called continuous backups, which automatically backs up your table data. Enabling continuous backups ensures that your table data is continuously backed up without the need for additional coding or manual interventions.
Export to Amazon S3: With continuous backups enabled, DynamoDB can directly export the backups to an Amazon S3 bucket. This eliminates the need for custom coding to export the data.
Minimal Coding: Option B requires the least amount of coding effort as continuous backups and the export to Amazon S3 functionality are built-in features of DynamoDB.
No Impact on Availability and RCUs: Enabling continuous backups and exporting data to Amazon S3 does not affect the availability of your application or the read capacity units (RCUs) defined for the table. These operations happen in the background and do not impact the table's performance or consume additional RCUs.
