Correct answer: Create an IAM role that includes the AWSGlueServiceRole policy. Attach the role to the crawler. Point the crawler to the S3 source path. Create a daily schedule to run the crawler. Specify a database name for the output..
Why this is the answer
The correct option ensures the AWS Glue crawler has the necessary permissions, knows where to find the data, and runs automatically to update the Data Catalog. The AWSGlueServiceRole policy grants Glue the permissions it needs to access S3 and write to the Data Catalog. Scheduling the crawler daily automates the cataloging process. Specifying a database name is essential for organizing the cataloged tables. Incorrect options: Attaching AmazonS3FullAccess is overly permissive; AWSGlueServiceRole is the standard and more secure choice for Glue. Writing output to a new S3 path is not a standard crawler function; crawlers update the Data Catalog. Allocating DPUs (Data Processing Units) is for Glue ETL jobs, not for crawlers. Crawlers consume resources but don't have configurable DPUs in the same way ETL jobs do. Similar to the first incorrect option, writing output to a new S3 path is not how crawlers operate; they populate the Data Catalog.
