- A
VPC Peering.
VPC Peering enables private routing between VPCs.
- B
VPC Endpoints.
Why wrong: VPC Endpoints provide private access to AWS services, not VPC-to-VPC.
- C
AWS Site-to-Site VPN.
Why wrong: VPN connects on-premises to VPC, not VPC-to-VPC.
- D
AWS Direct Connect.
Why wrong: Direct Connect is for dedicated on-premises connectivity.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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 migrating its SAP landscape to AWS and wants to ensure that all SAP systems can communicate with each other using private IP addresses only. The systems are deployed in multiple VPCs. Which AWS solution should be used to enable private connectivity between these VPCs?
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 Peering.
VPC Peering is the correct solution because it enables direct, private IP connectivity between VPCs using the AWS global network, with no gateways or VPN connections required. Traffic stays within AWS and never traverses the public internet, satisfying the requirement for SAP systems to communicate using only private IP addresses across multiple VPCs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Direct Connect is for dedicated on-premises connectivity.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse VPC Peering with VPC Endpoints, thinking both provide private connectivity, but VPC Endpoints only connect to AWS services, not to other VPCs.
Detailed technical explanation
How to think about this question
VPC Peering uses the AWS backbone to route traffic between VPCs via private IPv4 or IPv6 addresses, with no single point of failure or bandwidth bottleneck. It requires non-overlapping CIDR blocks and explicit route table entries for each peered VPC; transitive peering is not supported, so a full mesh or transit VPC architecture is needed for more than two VPCs. In real-world SAP landscapes, this is often combined with a Transit Gateway for hub-and-spoke connectivity when many VPCs are involved.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
