Exam question from Amazon's AWS Certified Data Engineer - Associate DEA-C01
Question #: 13
Topic #: 1
[All AWS Certified Data Engineer - Associate DEA-C01 Questions]

A company stores daily records of the financial performance of investment portfolios in .csv format in an Amazon S3 bucket. A data engineer uses AWS Glue crawlers to crawl the S3 data.
The data engineer must make the S3 data accessible daily in the AWS Glue Data Catalog.
Which solution will meet these requirements?

  • A. Create an IAM role that includes the AmazonS3FullAccess policy. Associate the role with the crawler. Specify the S3 bucket path of the source data as the crawler's data store. Create a daily schedule to run the crawler. Configure the output destination to a new path in the existing S3 bucket.
  • B. Create an IAM role that includes the AWSGlueServiceRole policy. Associate the role with the crawler. Specify the S3 bucket path of the source data as the crawler's data store. Create a daily schedule to run the crawler. Specify a database name for the output.
  • C. Create an IAM role that includes the AmazonS3FullAccess policy. Associate the role with the crawler. Specify the S3 bucket path of the source data as the crawler's data store. Allocate data processing units (DPUs) to run the crawler every day. Specify a database name for the output.
  • D. Create an IAM role that includes the AWSGlueServiceRole policy. Associate the role with the crawler. Specify the S3 bucket path of the source data as the crawler's data store. Allocate data processing units (DPUs) to run the crawler every day. Configure the output destination to a new path in the existing S3 bucket.

B. Create an IAM role that includes the AWSGlueServiceRole policy. Associate the role with the crawler. Specify the S3 bucket path of the source data as the crawler's data store. Create a daily schedule to run the crawler. Specify a database name for the output. Explanation: Option B correctly sets up the IAM role with the necessary permissions using the AWSGlueServiceRole policy, which is designed for use with AWS Glue. It specifies the S3 bucket path of the source data as the crawler's data store and creates a daily schedule to run the crawler. Additionally, it specifies a database name for the output, ensuring that the crawled data is properly cataloged in the AWS Glue Data Catalog.

Selected Answer: B
A,C are wrong because you use don't need full S3 access. D is wrong because you don't need to provision DPU and the destination should be a database, not an s3 bucket. so it's B

answer B is incomplete. Even we include AWSGlueServiceRole policy on IAM role, S3 access is not garantee

S3 access is part of the AWSGlueServiceRole Policy https://docs.aws.amazon.com/aws-managed- policy/latest/reference/AWSGlueServiceRole.html

It adds only for the glue related buckets, but it doesnt grant permissions for S3 that we need to read in order to fetch data, isnt it ?
