- A
Internet Gateway
Why wrong: Internet Gateways route traffic through the public internet — VPC Endpoints specifically eliminate the need to use the internet for AWS service access.
- B
NAT Gateway
Why wrong: NAT Gateways allow private subnet resources to access the internet — VPC Endpoints provide private connectivity without any internet path.
- C
VPC Endpoints
VPC Endpoints enable private connectivity to AWS services from within a VPC — traffic stays on the AWS network, never traversing the public internet.
- D
VPC Peering
Why wrong: VPC Peering connects two VPCs together — it doesn't provide private access to AWS managed services like S3 or DynamoDB.
Question 909 of 1,024
VPC Endpoints: Private Connectivity to AWS Services
This CLF-C02 practice question tests your understanding of cloud technology and services. 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.
Which AWS service provides private connectivity between VPCs and supported AWS services without requiring internet gateway, NAT device, VPN, or Direct Connect?
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
✓
VPC Endpoints
VPC Endpoints (specifically Gateway Endpoints for S3/DynamoDB and Interface Endpoints for other services) enable private connectivity between a VPC and supported AWS services using the AWS network, without requiring an internet gateway, NAT device, VPN, or Direct Connect. Traffic stays within the AWS backbone and never traverses the public internet, leveraging AWS PrivateLink for interface endpoints or route table entries for gateway endpoints.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse VPC Peering (Option D) as a way to access AWS services privately, but VPC Peering only connects VPCs, not services, and does not eliminate the need for internet gateways or NAT devices for service access.
Detailed technical explanation
How to think about this question
VPC Endpoints use AWS PrivateLink for interface endpoints, which creates an Elastic Network Interface (ENI) in the subnet with a private IP address, allowing traffic to reach supported services like SQS, SNS, or KMS without leaving the AWS network. Gateway endpoints for S3 and DynamoDB work by adding prefix lists to the VPC route table, enabling traffic to those services via the AWS backbone without any ENI. A real-world scenario is a compliance requirement to avoid internet egress for data transfer to S3, where a gateway endpoint ensures all traffic stays within the AWS network.
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.

| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
