- A
Grant 'Super' permission on the Data Catalog
Why wrong: Super is too broad and grants admin access.
- B
Add the IAM role to the Lake Formation administrators group
Why wrong: Admin group grants full access, not just read.
- C
Grant 'Select' on the database and select 'Include' to apply to all tables
This grants read access to all tables in one operation.
- D
Grant 'Describe' on the database and 'Select' on each table individually
Why wrong: Individual grants are time-consuming.

DEA-C01 Data Ingestion and Transformation Practice Question
This DEA-C01 practice question tests your understanding of data ingestion and transformation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A company uses AWS Lake Formation to manage data lake permissions. A data engineer needs to grant an IAM role 'Read' access to a specific database and all its tables in the Data Catalog. What is the MOST efficient way to achieve this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Grant 'Select' on the database and select 'Include' to apply to all tables
Option C is correct because Lake Formation allows granting 'Select' permission on a database with the 'Include' option, which automatically applies the same permission to all current and future tables in that database. This is the most efficient way to grant read access to an IAM role for a specific database and all its tables in the Data Catalog, as it avoids manual per-table grants.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Grant 'Super' permission on the Data Catalog
Why it's wrong here
Super is too broad and grants admin access.

Add the IAM role to the Lake Formation administrators group
Why it's wrong here
Admin group grants full access, not just read.
- ✓
Grant 'Select' on the database and select 'Include' to apply to all tables
Why this is correct
This grants read access to all tables in one operation.

- ✗
Grant 'Describe' on the database and 'Select' on each table individually
Why it's wrong here
Individual grants are time-consuming.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse 'Super' or admin roles with a simple read grant, or think that granting 'Describe' on the database is sufficient for read access, when in fact 'Select' on the tables is required for data access.
Detailed technical explanation
How to think about this question
Under the hood, Lake Formation uses a fine-grained access control model that integrates with AWS Glue Data Catalog and IAM. When you grant 'Select' with 'Include' on a database, Lake Formation creates a grant that applies to all tables under that database, leveraging the hierarchical nature of the Data Catalog. This is particularly useful in data lake architectures where new tables are frequently added, as it ensures consistent permissions without manual updates.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
