The correct combination is to enable Redshift audit logging and create views that expose only non-sensitive columns, granting access to those views. This works because Redshift audit logging captures all query activity at the cluster level, meeting the logging requirement, while views act as a security layer that restricts column-level access by exposing only permitted columns to non-admin users—a technique known as column-level access control through view-based masking. On the AWS Certified Data Engineer Associate DEA-C01 exam, this scenario tests your understanding that Redshift lacks native column-level security, so views are the standard workaround, and it’s a common trap to confuse IAM policies or row-level security with column-level control. Remember the memory tip: “Logs catch the action, views block the column”—audit logging handles the query trail, and views handle the sensitive data gate.
DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 Redshift for analytics. The security team requires that all queries be logged and that any access to sensitive columns be blocked for non-admin users. Which combination of features should the data engineer implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Redshift audit logging and create views that expose only non-sensitive columns, granting access to views.
Option C is correct because Redshift audit logging captures queries, and column-level access control can be enforced using views with restricted columns. Option A is wrong because IAM policies do not control column-level access in Redshift. Option B is wrong because row-level security is not yet supported. Option D is wrong because CloudWatch Logs do not control access.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Enable Redshift audit logging and create views that expose only non-sensitive columns, granting access to views.
Why this is correct
Views can restrict column access, and audit logging captures queries.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use Redshift row-level security and enable CloudTrail logging.
Why it's wrong here
Row-level security in Redshift is not available.
✗
Enable CloudWatch Logs for Redshift and use IAM conditions to block sensitive columns.
Why it's wrong here
CloudWatch Logs do not provide column-level access control.
✗
Enable Redshift audit logging and use IAM policies to restrict column access.
Why it's wrong here
IAM policies cannot restrict column-level access within Redshift.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DEA-C01 NAT questions on configuration and troubleshooting.
