DEA-C01 Data Security and Governance Practice Question
A data engineer needs to ensure that an Amazon Redshift cluster encrypts all data at rest. Which setting must be enabled when creating the cluster?
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
Amazon Redshift encryption at rest is enabled during cluster creation by selecting the encryption option. Option A is incorrect because enabling automated snapshots is for backup and recovery, not encryption. Option C is incorrect because SSL/TLS ensures encryption in transit, not at rest. Option D is incorrect because VPC is for network isolation, not encryption.
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 automated snapshots
Why it's wrong here
Automated snapshots govern backup frequency and retention, not encryption of cluster data or snapshots. Encryption at rest is set through the cluster's encrypted attribute and KMS key. Snapshots are the correct concern when addressing recovery point objectives, not data-at-rest protection.
- ✓
Enable encryption
Why this is correct
Enabling encryption on the cluster applies AWS KMS-backed encryption to all data at rest, including the cluster's storage volumes and snapshots. This directly satisfies the stem's requirement that the Redshift cluster encrypt all data at rest, and it is the setting exposed during cluster creation.
- ✗
Enable SSL/TLS
Why it's wrong here
SSL is for encryption in transit.
- ✗
Enable VPC
Why it's wrong here
VPC is for network isolation.
