- A
Create an S3 gateway VPC endpoint and update the route tables for the private subnets.
An S3 gateway endpoint provides private access to S3 without sending traffic over the internet. It is the correct endpoint type for S3 and integrates through route tables.
- B
Place a NAT gateway in the public subnet so the private instances can reach AWS services.
Why wrong: A NAT gateway sends outbound traffic to the internet and adds cost and exposure that the requirement explicitly forbids. It is not a private-only connectivity solution.
- C
Create an interface VPC endpoint for AWS Secrets Manager and allow the workload security group to reach it.
Secrets Manager uses an interface endpoint for private connectivity. This keeps API calls inside the AWS network and avoids the need for internet access or NAT.
- D
Assign public IPv4 addresses to the instances and restrict them with security groups.
Why wrong: Public IPs contradict the requirement to stay private and do not remove internet exposure. Security groups alone do not make a workload private.
- E
Use VPC peering to the AWS service endpoints instead of VPC endpoints.
Why wrong: VPC peering is for connectivity between VPCs, not for reaching managed AWS service endpoints. It is not the right mechanism for private service access.
SAA-C03 Design Secure Architectures Practice Question
This SAA-C03 practice question tests your understanding of design secure architectures. 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. A key principle to apply: gateway VPC endpoints are for S3 and DynamoDB only.. 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 workload runs in private subnets and must reach Amazon S3 and AWS Secrets Manager without using the internet or a NAT gateway. The team wants to keep the traffic on AWS private networking and avoid public IPs. Which two changes should the architect make? Select two.
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
Create an S3 gateway VPC endpoint and update the route tables for the private subnets.
Option A is correct because an S3 gateway VPC endpoint enables private subnet instances to access S3 over the AWS network without requiring internet gateways or NAT gateways. Gateway endpoints use route table entries to direct S3 traffic through the AWS backbone, avoiding public IPs entirely.
Key principle: Gateway VPC endpoints are for S3 and DynamoDB only.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create an S3 gateway VPC endpoint and update the route tables for the private subnets.
- ✗
Place a NAT gateway in the public subnet so the private instances can reach AWS services.
- ✓
Create an interface VPC endpoint for AWS Secrets Manager and allow the workload security group to reach it.
- ✗
Assign public IPv4 addresses to the instances and restrict them with security groups.
Why it's wrong here
Public IPs contradict the requirement to stay private and do not remove internet exposure. Security groups alone do not make a workload private.
- ✗
Use VPC peering to the AWS service endpoints instead of VPC endpoints.
Why it's wrong here
VPC peering is for connectivity between VPCs, not for reaching managed AWS service endpoints. It is not the right mechanism for private service access.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse gateway endpoints (for S3 and DynamoDB) with interface endpoints (for most other services) and may incorrectly assume a NAT gateway is needed for all AWS service access, ignoring that gateway endpoints provide a free, internet-free alternative for S3.
Detailed technical explanation
How to think about this question
Gateway VPC endpoints for S3 use prefix lists in route tables to route traffic directly to S3 via the AWS global network, while interface VPC endpoints for Secrets Manager use Elastic Network Interfaces (ENIs) with private IPs in the subnet, secured by security groups. Both types leverage AWS PrivateLink, ensuring traffic never traverses the public internet and remains within the AWS backbone.
KKey Concepts to Remember
- Gateway VPC endpoints are for S3 and DynamoDB only.
- Interface VPC endpoints use PrivateLink and ENIs.
- Gateway endpoints are configured via route tables.
- Interface endpoints require security group configuration.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Gateway VPC endpoints are for S3 and DynamoDB only.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
