DEA-C01 Data Security and Governance Practice Question
A data engineer is setting up an Amazon Redshift cluster. Which TWO measures can be taken to secure the data at rest?
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
✓
Enable encryption on the Redshift cluster using AWS KMS
Redshift supports encryption at rest using KMS or HSM. Cluster encryption can be enabled at launch. Client-side encryption before loading protects data before it reaches Redshift, but not necessarily at rest. VPC security groups control network access. IAM roles control who can access the cluster.
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 encryption on the Redshift cluster using AWS KMS
Why this is correct
KMS encryption protects data at rest in Redshift.
- ✗
Encrypt data on the client side before loading into Redshift
Why it's wrong here
Client-side encryption does not ensure data at rest is encrypted in Redshift.
- ✗
Enable AWS IAM database authentication
Why it's wrong here
IAM authentication controls access, not encryption.
- ✗
Use VPC security groups to restrict network access
Why it's wrong here
Security groups control network access, not data at rest encryption.
- ✓
Use an HSM (Hardware Security Module) to manage encryption keys
Why this is correct
Redshift supports HSM for encryption key management.
