Quick Answer
The correct answer is to create a VPC Gateway Endpoint for DynamoDB. This solution works because a Gateway Endpoint uses AWS’s internal backbone to route traffic from your EC2 instances directly to DynamoDB without ever leaving the VPC or traversing the public internet, ensuring compliance with the security requirement. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this question tests your understanding of VPC endpoint types and their specific use cases—a common trap is confusing Gateway Endpoints (used for DynamoDB and S3) with Interface Endpoints (used for services like API Gateway or Kinesis). Remember that DynamoDB is one of only two services that exclusively use Gateway Endpoints, so when you see “private access to DynamoDB from EC2,” your first instinct should be Gateway, not Interface. A quick memory tip: “Gateway for the big two—S3 and DynamoDB keep traffic inside with you.”
This ANS-C01 practice question tests your understanding of network security, compliance 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.
An application running on EC2 instances needs to access a DynamoDB table. The security team requires that traffic does not traverse the internet. Which solution should be used?
Create a VPC Gateway Endpoint for DynamoDB.
Provides private connectivity to DynamoDB.
Create a VPC Interface Endpoint for DynamoDB.
Why wrong: DynamoDB uses Gateway Endpoint, not Interface Endpoint.
Attach an Internet Gateway to the VPC.
Why wrong: Provides internet access.
Deploy a NAT gateway and update the route table.
Why wrong: NAT gateway routes to the internet.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create a VPC Gateway Endpoint for DynamoDB.
Option B is correct because a VPC Gateway Endpoint for DynamoDB provides private access. Option A is wrong because a NAT gateway routes to the internet. Option C is wrong because an Internet Gateway provides internet access. Option D is wrong because a VPC Interface Endpoint is for services like API Gateway, but DynamoDB uses Gateway Endpoint.
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
For each option: why learners choose it and why it is or isn't the right answer here.
Create a VPC Gateway Endpoint for DynamoDB.
Why this is correct
Provides private connectivity to DynamoDB.
Related concept
Static NAT maps one inside address to one outside address.
Create a VPC Interface Endpoint for DynamoDB.
Why it's wrong here
DynamoDB uses Gateway Endpoint, not Interface Endpoint.
Attach an Internet Gateway to the VPC.
Why it's wrong here
Provides internet access.
Deploy a NAT gateway and update the route table.
Common exam traps
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
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.
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
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
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 ANS-C01 NAT questions on configuration and troubleshooting.
