    Topic 1: AWS Certified Data Engineer - Associate

    A company currently stores all of its data in Amazon S3 by using the S3 Standard storage class.

Between 6 months and 2 years, most data files are accessed once or twice each month. After 2 years, data files are accessed only once or twice each year.

    The data engineer needs to use an S3 Lifecycle policy to develop new data storage rules. The new storage solution must continue to provide high availability.
