Now, let's practice a few exam-style questions:

  1. Amazon Athena is being used by a large company to query data that's being held in S3 buckets in the eu-central-1 and eu-west-1 regions. The company wants to use Athena in eu-west-1 to query data from Amazon S3 in both regions. The solution must be as low-cost as possible.
