Quick Answer
The answer is AWS Site-to-Site VPN, which is the correct service for establishing secure connectivity between a corporate network and SAP S/4HANA on AWS. This service creates an encrypted IPsec tunnel between the on-premises VPN device and a Virtual Private Gateway (VGW) attached to the VPC hosting the SAP workload, ensuring all traffic between the two environments is protected over the public internet. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of hybrid networking for SAP, often appearing in scenarios where you must differentiate between AWS Site-to-Site VPN, AWS Direct Connect, and Client VPN. A common trap is choosing Direct Connect for security reasons, but the question explicitly asks for a VPN connection over the internet, not a dedicated private link. Remember the memory tip: “Site-to-Site for SAP’s secure site link” — if the requirement says “secure VPN connection” without specifying dedicated private lines, think IPsec tunnel via a VGW.
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 is planning to run SAP S/4HANA on AWS. They need to ensure that the SAP system can be accessed from the corporate network via a secure VPN connection. Which AWS service should be used to establish this connectivity?
AWS Client VPN
Why wrong: Client VPN is for individual remote devices, not site-to-site.
AWS Transit Gateway
Why wrong: Transit Gateway is a hub for interconnecting VPCs and on-premises networks.
AWS Site-to-Site VPN
Provides secure IPsec VPN between corporate network and AWS VPC.
AWS Direct Connect
Why wrong: Direct Connect is a dedicated physical connection, not a VPN.

Correct answer & explanation
AWS Site-to-Site VPN
AWS Site-to-Site VPN creates a secure IPsec tunnel between the corporate network's on-premises VPN device and a Virtual Private Gateway (VGW) attached to the VPC hosting the SAP S/4HANA system. This enables encrypted communication over the public internet, meeting the requirement for secure VPN connectivity from the corporate network to the SAP workload.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Client VPN
Why it's wrong here
Client VPN is for individual remote devices, not site-to-site.
AWS Transit Gateway
Why it's wrong here
Transit Gateway is a hub for interconnecting VPCs and on-premises networks.
AWS Site-to-Site VPN
AWS Direct Connect
Why it's wrong here
Direct Connect is a dedicated physical connection, not a VPN.
Common exam traps
The trap here is that candidates confuse AWS Client VPN (remote access for individual users) with Site-to-Site VPN (network-to-network connectivity), or assume Transit Gateway alone provides VPN connectivity without understanding it requires a VPN attachment.
Detailed technical explanation
AWS Site-to-Site VPN supports both static and dynamic routing (BGP) using Virtual Private Gateways or Transit Gateways. The IPsec tunnels use IKEv1 or IKEv2 with AES 128/256-bit encryption, and each VPN connection includes two tunnels for high availability. In real-world SAP deployments, BGP is often preferred to advertise the SAP system's subnets and enable automatic failover between tunnels.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
