AWS Elastic Beanstalk stores your application files and optionally server log files in ____.

A.
Amazon Storage Gateway

B.
Amazon Glacier

C.
Amazon EC2

D.
Amazon S3

Explanation:
AWS Elastic Beanstalk stores your application files and optionally server log files in Amazon S3. If you are using the
AWS Management Console, Git, the AWS Toolkit for Visual Studio, or AWS Toolkit for Eclipse, an Amazon S3 bucket
will be created in your account for you and the files you upload will be automatically copied from your local client to
Amazon S3. Optionally, you may configure Elastic Beanstalk to copy your server log files every hour to Amazon S3. You
do this by editing the environment configuration settings.
