- A
Ensure that the users query the table through a service integrated with Lake Formation, such as Athena.
Lake Formation enforces permissions when queries are run through integrated services.
- B
Grant the IAM role SELECT permission on the table with column-level restrictions.
Permissions are granted to IAM roles or users.
- C
Create a view in the Data Catalog that exposes only the required columns.
Why wrong: Creating a view is an alternative but not a step for Lake Formation column-level control.
- D
Define a Lake Formation data permissions policy that includes column-level filtering.
Lake Formation permissions can specify which columns are accessible.
- E
Attach an S3 bucket policy to restrict access to the underlying data.
Why wrong: S3 bucket policies are not fine-grained to column level.
Quick Answer
The correct answer involves defining a Lake Formation data permissions policy that includes column-level filtering, granting those permissions to the IAM role, and ensuring the user accesses the data through Lake Formation-enabled services. This works because Lake Formation acts as a centralized permission engine that intercepts requests at the column level, applying fine-grained access control before the data is returned from the underlying Amazon S3 storage. On the AWS Certified Data Engineer Associate DEA-C01 exam, this scenario tests your understanding that column-level access is managed entirely within Lake Formation, not through S3 bucket policies or by bypassing the registration process. A common trap is assuming S3 policies can handle column-level restrictions—they cannot, as S3 operates only at the object or prefix level. Remember the mnemonic "P-G-R": define the Policy, Grant to the role, and use Registered services.
DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. 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 is using AWS Lake Formation to manage a data lake. The data engineer needs to set up fine-grained access control so that users can only see specific columns in a table based on their IAM role. Which THREE steps should the data engineer take?
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
Ensure that the users query the table through a service integrated with Lake Formation, such as Athena.
Options A, B, and D are correct. Lake Formation column-level access requires defining the policy in Lake Formation, granting permissions to the IAM role, and the user must use Lake Formation-enabled services. Option C is wrong because S3 bucket policies are not used for column-level control. Option E is wrong because the table must be registered with Lake Formation.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
