- A
The RLS permissions dataset is not correctly configured to map users to department values.
Correct. The permissions dataset likely has incorrect or incomplete mappings, causing RLS to not apply.
- B
The 'Department' column is not included in the dataset.
Why wrong: Incorrect. The scenario states the 'Department' column is included in the dataset.
- C
The users have been granted admin access to the QuickSight dashboard.
Why wrong: Incorrect. Admin access to a dashboard does not override RLS rules on the underlying dataset.
- D
The SPICE dataset does not support row-level security.
Why wrong: Incorrect. SPICE datasets support row-level security when properly configured.

DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 Amazon QuickSight for data visualization. The data engineer needs to ensure that users can only see data relevant to their department. The data is stored in Amazon S3 and is accessed via SPICE. The engineer has created datasets in QuickSight and wants to implement row-level security (RLS). The dataset contains a column 'Department' that indicates which department a row belongs to. The engineer has configured RLS rules using a separate permissions dataset. However, users report that they can see all rows, not just their department's rows. What is the most likely reason?

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
✓
The RLS permissions dataset is not correctly configured to map users to department values.
Option A is the most likely reason because the RLS permissions dataset must correctly map each user to the specific department values they are allowed to see. If this mapping is misconfigured or missing, QuickSight will default to showing all rows, making the RLS ineffective. The 'Department' column is present in the dataset (Option B is false). Admin access to the dashboard does not bypass RLS at the dataset level (Option C is false). SPICE datasets fully support row-level security (Option D is false).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Incorrect. SPICE datasets support row-level security when properly configured.
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.
Trap categories for this question
Scenario analysis trap
Incorrect. The scenario states the 'Department' column is included in the dataset.
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.
