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 data engineer needs to ensure that an Amazon Redshift cluster encrypts all data at rest. Which setting must be enabled when creating the cluster?
Enable automated snapshots
Why wrong: Snapshots are for backup.
Enable encryption
Redshift supports encryption at rest.
Enable SSL/TLS
Why wrong: SSL is for encryption in transit.
Enable VPC
Why wrong: VPC is for network isolation.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable encryption
Option B is correct. Redshift cluster encryption is enabled at creation. Option A is wrong because SSL is for in-transit. Option C is wrong because VPC is network isolation. Option D is wrong because automated snapshots are for backup.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
