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 uses Amazon Redshift for its data warehouse and needs to enforce column-level security on sensitive columns. Which TWO approaches can achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create views that expose only non-sensitive columns and grant access to the views.
Options A and D are correct. Redshift column-level security allows defining access controls at the column level. Views can also restrict column access. Option B is wrong because row-level security does not restrict columns. Option C is wrong because S3 bucket policies are unrelated. Option E is wrong because Redshift Spectrum queries external data, not column-level control.
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.
✗
Apply an S3 bucket policy to the underlying data files.
Why it's wrong here
Redshift stores data in its own managed storage.
✓
Create views that expose only non-sensitive columns and grant access to the views.
Why this is correct
Views can limit column visibility.

Read the scenario before looking for a memorised answer.
✗
Use Redshift Spectrum to query external tables and restrict columns via the external schema.
Why it's wrong here
Redshift Spectrum is for querying S3 data, not for column-level security.
✓
Use Redshift column-level security to grant or revoke permissions on specific columns.
Why this is correct
Column-level security is a native Redshift feature.

✗
Use Redshift row-level security policies to restrict column access.
Why it's wrong here
Row-level security restricts rows, not columns.
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.
