The answer is a Virtual Private Gateway (VGW) and BGP peering between the on-premises router and the AWS router. A VGW is mandatory because it serves as the attachment point for your VPC to the Direct Connect virtual interface, allowing private IP traffic to flow between your on-premises network and the SAP HANA environment in AWS. Without the VGW, the Direct Connect connection cannot terminate inside the VPC, which is critical for the low-latency, private network path that SAP HANA hybrid connectivity demands. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this concept tests your understanding of how to establish a dedicated, secure link for SAP workloads, often appearing in scenario-based questions where a candidate might mistakenly choose a VPN-only solution or forget the VGW requirement. A common trap is assuming Direct Connect alone provides VPC access, but the VGW is the essential glue. Memory tip: think of the VGW as the "gatekeeper" that lets Direct Connect into your VPC, while BGP is the "handshake" that keeps routes stable.
PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 TWO of the following are required when integrating SAP HANA with AWS Direct Connect for hybrid connectivity?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A Virtual Private Gateway attached to the VPC.
A Virtual Private Gateway (VGW) is required to attach the VPC to the Direct Connect connection, enabling private IP traffic between on-premises and the VPC. Without a VGW, the Direct Connect virtual interface cannot terminate within the VPC, making hybrid connectivity impossible for SAP HANA workloads that require low-latency, private network paths.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
A Public Virtual Interface to access the VPC.
Why it's wrong here
Public VIF is for public endpoints, not VPC.
✓
A Virtual Private Gateway attached to the VPC.
Why this is correct
VGW is required for Direct Connect private VIF.

✗
A VPN tunnel between on-premises and AWS.
Why it's wrong here
Direct Connect is a dedicated connection, not VPN.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse a Public Virtual Interface with a Private Virtual Interface, assuming any Direct Connect interface can reach the VPC, but only a Private Virtual Interface combined with a VGW provides private VPC access.
Detailed technical explanation
How to think about this question
Under the hood, the VGW acts as the Amazon-side endpoint for BGP sessions over the Private Virtual Interface, exchanging routes via eBGP (typically using ASN 64512 for the VGW). For SAP HANA, consistent latency below 1 ms is critical, and Direct Connect bypasses internet transit, while the VGW ensures traffic stays within AWS’s private network backbone. In a real-world scenario, if the VGW is not attached, the Direct Connect virtual interface will remain in a 'down' state because there is no target for route propagation.

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 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.
