Chapter 11

1. 4

Enabling cross-region replication to pull all the s3 data into one region would work, but it isn't cost-efficient.

DMS cannot migrate a Glue catalog.

You cannot give permission for Glue to read another catalog in this way.

Glue can create a data catalog across all regions allowing Athena to query them, so this is the correct answer.

2. 3

RDS will work but it is not cost-effective.

Redshift will work but it is not cost-effective.

Athena can directly query data from S3, so this is the most cost-effective solution.

Using EC2 to do this is complex and unnecessary.

3. 2

Athena cannot query directly from Glacier.

Moving the data to standard S3 is the most cost-effective solution.

DynamoDB and Redshift would work, but they are not as cost-effective.

4. 3 and 5

Revoking permissions is not a good solution.

Deletion protection does not exist for stacks.

Termination protection is a good solution, so...
