DEA-C01 Data Security and Governance Practice Question
A data engineer is configuring a VPC for an Amazon Redshift cluster. The cluster must be accessible only from a specific on-premises network via a Direct Connect connection. Which TWO actions should the engineer take to meet this requirement? (Choose TWO.)

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
✓
Configure a security group to allow inbound traffic from the on-premises CIDR block.
To restrict access to an Amazon Redshift cluster from a specific on-premises network via Direct Connect, the engineer should use a security group (option B) to control inbound traffic at the instance level, and a network ACL (option C) for subnet-level traffic control. Both should allow traffic from the on-premises CIDR block. Option A (Enhanced VPC Routing) is incorrect because it controls how traffic flows between the cluster and other resources, not inbound access. Option D (VPC endpoint) is incorrect because a VPC endpoint provides private connectivity from within the VPC, not from on-premises via Direct Connect. Option E (publicly accessible) is insecure and unnecessary when using Direct Connect.
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 Enhanced VPC Routing.
Why it's wrong here
Enhanced VPC Routing controls traffic routing, not access.
- ✓
Configure a security group to allow inbound traffic from the on-premises CIDR block.
Why this is correct
Security groups act as a firewall to control inbound traffic.
- ✓
Configure a network ACL to allow inbound traffic from the on-premises CIDR block.
Why this is correct
Network ACLs provide an additional layer of subnet-level security.
- ✗
Create a VPC endpoint for Redshift.
Why it's wrong here
Redshift does not use VPC endpoints; it uses security groups and NACLs.
- ✗
Make the Redshift cluster publicly accessible.
Why it's wrong here
Public accessibility would allow access from the internet, which is not desired.
