- A
AWS Direct Connect
Why wrong: AWS Direct Connect is a dedicated network connection from on-premises to AWS, not for connecting subnets within the same VPC.
- B
VPC peering connection
VPC peering connects different VPCs, not subnets within the same VPC.
- C
AWS Site-to-Site VPN
Why wrong: AWS Site-to-Site VPN connects on-premises networks to AWS, not for intra-VPC subnet communication.
- D
AWS Transit Gateway
Why wrong: AWS Transit Gateway is used for hub-and-spoke connectivity between multiple VPCs or on-premises, not for subnets within a single VPC.

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. 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 designing a multi-tier SAP architecture on AWS. They want to separate the SAP application tier and database tier into different subnets for security. Which AWS networking component should they use to connect the tiers?
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 connection
The SAP application and database tiers should be placed in separate VPCs for enhanced security. VPC peering allows these VPCs to communicate with each other using private IP addresses. Although the question mentions 'subnets', the correct solution is VPC peering to connect tiers across different VPCs.
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.
- ✗
AWS Direct Connect
Why it's wrong here
AWS Direct Connect is a dedicated network connection from on-premises to AWS, not for connecting subnets within the same VPC.
- ✓
VPC peering connection
Why this is correct
VPC peering connects different VPCs, not subnets within the same VPC.

AWS Site-to-Site VPN
Why it's wrong here
AWS Site-to-Site VPN connects on-premises networks to AWS, not for intra-VPC subnet communication.
- ✗
AWS Transit Gateway
Why it's wrong here
AWS Transit Gateway is used for hub-and-spoke connectivity between multiple VPCs or on-premises, not for subnets within a single VPC.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates may misread 'different subnets' as 'different VPCs' and choose VPC peering, but the tiers are within the same VPC, so no extra networking component is needed.
Detailed technical explanation
How to think about this question
VPC peering uses the existing AWS infrastructure to route traffic between VPCs without any gateway or VPN appliance, leveraging the AWS global network for high throughput and low latency. It does not support transitive routing, meaning if VPC A is peered with VPC B and VPC B is peered with VPC C, VPC A cannot communicate with VPC C through VPC B—each pair must have a direct peering connection. In SAP environments, this non-transitive behavior is acceptable because the application and database tiers are typically only two VPCs, but it becomes a limitation in larger multi-VPC designs where Transit Gateway would be more appropriate.
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.
