- A
Create a VPC Gateway Endpoint for S3.
Correct. A VPC Gateway Endpoint provides private connectivity to S3 within the same region without internet exposure.
- B
Deploy a NAT Gateway in the public subnet and add a route to the private subnet's route table.
Why wrong: Incorrect. NAT Gateway provides outbound internet access, but traffic to S3 would still go over the internet, not private.
- C
Attach an Internet Gateway to the VPC and add a default route in the private subnet's route table.
Why wrong: Incorrect. An Internet Gateway alone does not provide private subnet access; it requires a NAT device for instances without public IPs, and traffic would traverse the internet.
- D
Set up an AWS Direct Connect connection to the S3 bucket.
Why wrong: Incorrect. Direct Connect is a dedicated network connection from on-premises to AWS, not needed for intra-region S3 access from EC2.
SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. 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 company has a VPC with public and private subnets. An Amazon EC2 instance in a private subnet needs to access an Amazon S3 bucket in the same AWS Region. The SysOps administrator wants to ensure the traffic does not traverse the internet. Which solution should be implemented?
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 a VPC Gateway Endpoint for S3.
A VPC Gateway Endpoint for S3 allows instances in a private subnet to access S3 without traversing the internet. It uses AWS's internal network, routing traffic through a prefix list in the route table, ensuring data stays within the AWS backbone. This meets the requirement of no internet traversal while providing secure, low-latency access to S3.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Gateway Endpoints with Interface Endpoints or assume a NAT Gateway is required for private subnet outbound traffic, overlooking that S3 and DynamoDB can be accessed via Gateway Endpoints without internet connectivity.
Detailed technical explanation
How to think about this question
VPC Gateway Endpoints use route table entries with a prefix list for the S3 service (e.g., com.amazonaws.region.s3) to direct traffic through AWS's private network. Unlike Interface Endpoints (powered by AWS PrivateLink), Gateway Endpoints do not require an Elastic Network Interface or additional hourly charges, making them cost-effective for S3 and DynamoDB access. Under the hood, traffic is routed via the AWS global infrastructure, bypassing internet gateways and NAT devices entirely.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
