DEA-C01 Data Store Management Practice Question

This DEA-C01 practice question tests your understanding of data store management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

      "Resource": "arn:aws:s3:::my-data-lake/*"
    }
  ]
}

An IAM role 'DataLakeRole' has the above S3 bucket policy attached to an S3 bucket. The role is assumed by an AWS Glue job. The Glue job is failing with 'Access Denied' errors when trying to list objects in the bucket. Which action should be added to the policy to fix the issue?

}

A
Add s3:ListObjects action for the bucket ARN.
Why wrong: s3:ListObjects is a valid IAM action, but it only covers the older ListObjects API. AWS Glue uses the ListObjectsV2 API, which requires the s3:ListBucket action. Additionally, the action must be applied to the bucket ARN, not the object ARN.
B
Add s3:ListBucket action for the bucket ARN (arn:aws:s3:::my-data-lake).
Correct. s3:ListBucket on the bucket ARN grants permission to list objects using both ListObjects and ListObjectsV2 APIs, which is what Glue needs.
C
Add s3:GetObjectVersion action for the object ARN.
Why wrong: s3:GetObjectVersion is for retrieving a specific version of an object, not for listing objects. It does not help with listing the bucket contents.
D
Add s3:ListBucket action for the object ARN (arn:aws:s3:::my-data-lake/*).
Why wrong: s3:ListBucket on the object ARN (arn:aws:s3:::my-data-lake/*) is invalid because ListBucket applies to the bucket itself, not to objects. The correct resource for ListBucket is the bucket ARN without the /* suffix.

Correct answer & explanation

✓

Add s3:ListBucket action for the bucket ARN (arn:aws:s3:::my-data-lake).

The Glue job is failing with 'Access Denied' when trying to list objects, which requires the s3:ListBucket permission on the bucket itself (not on objects). Option B correctly adds s3:ListBucket for the bucket ARN (arn:aws:s3:::my-data-lake), which grants permission to list the contents of the bucket. Without this action, even if other permissions exist, the ListObjectsV2 API call used by AWS Glue to enumerate objects will be denied.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse s3:ListBucket (which applies to the bucket itself) with s3:GetObject or s3:ListObjects (which are often misapplied to object ARNs), leading them to pick Option D or A, not realizing that listing requires the bucket-level permission and a bucket ARN, not an object ARN.

Detailed technical explanation

How to think about this question

Under the hood, the S3 ListObjectsV2 API call requires the s3:ListBucket permission on the bucket resource, not on individual objects. AWS Glue jobs use the AWS SDK's list_objects_v2() method, which maps directly to this permission. A common subtlety is that the bucket policy must explicitly allow s3:ListBucket for the bucket ARN (without any path), and the IAM role's trust policy must also allow the Glue service to assume the role; if the role lacks sts:AssumeRole, the job will fail before even reaching S3.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

TExam Day Tips

Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Storage Class	Min Duration	Retrieval	Use Case

S3 Standard-IA	30 days	Immediate	Infrequent access, rapid retrieval
S3 One Zone-IA	30 days	Immediate	Non-critical infrequent data
S3 Intelligent-Tiering	None	Immediate–hours	Unknown or changing access patterns
S3 Glacier Instant	90 days	Milliseconds	Archive with instant retrieval
S3 Glacier Flexible	90 days	Minutes–hours	Archive, flexible retrieval
