PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP workload is running on an EC2 instance in a private subnet. The application needs to access an S3 bucket for backups. Which AWS service should be used to enable private connectivity without traversing the internet?
⚠ Common exam trap
Many exam-takers confuse NAT Gateway with providing private connectivity, but NAT Gateway still routes traffic through the internet, whereas a VPC Endpoint keeps traffic entirely within the AWS network.

Correct answer & explanation
✓
VPC Endpoint (Gateway)
A VPC Endpoint (Gateway) allows private connectivity between an EC2 instance in a private subnet and an S3 bucket without traversing the internet. It uses AWS’s internal network and route table entries to direct S3 traffic through the endpoint, ensuring data never leaves the AWS backbone. This is the correct choice for SAP workloads requiring secure, low-latency backups to S3.
