Review

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.

What is the best solution?

  1. Enable S3 cross-region replication from eu-central-1 to eu-west-1. Run the AWS Glue crawler in eu-west-1 to create the AWS Glue Data Catalog and run Athena queries.
  2. Use AWS DMS to migrate the AWS Glue Data Catalog from eu-central-1 to eu-west-1. Run Athena queries in eu-west-1.
  3. Update the AWS Glue resource policy's IAM permissions to provide the eu-central-1 AWS Glue Data Catalog with access to eu-west-1. Once the catalog in eu-west-1 has access to the catalog in eu-central-1, run Athena queries in eu-west-1.
  4. Run the AWS Glue crawler in eu-west-1 to catalog the datasets in all regions...
