- A
AWS Transit Gateway
Why wrong: AWS Transit Gateway is a network transit hub that connects VPCs and on-premises networks. While it can be used with VPN attachments, it does not directly extend IP addresses; the VPN component is needed for that.
- B
VPC Peering
Why wrong: VPC Peering connects two VPCs in the same or different accounts/regions. It does not extend an on-premises network to AWS.
- C
AWS Site-to-Site VPN
AWS Site-to-Site VPN creates a secure tunnel between the on-premises network and the VPC, enabling the use of the same private IP addresses in the VPC.
- D
AWS Direct Connect
Why wrong: AWS Direct Connect provides a dedicated private connection but does not inherently preserve IP addresses; it typically requires a VPN or BGP configuration to extend addressing.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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 on-premises application to AWS and needs to maintain the same private IP addresses for the application servers. The on-premises network uses 10.0.0.0/16. Which AWS service allows the company to extend its on-premises network to AWS and preserve IP addresses?
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
AWS Site-to-Site VPN
The correct answer is AWS Site-to-Site VPN (Option C). This service creates an encrypted connection between the on-premises network and the VPC, allowing the company to extend its on-premises IP address range (10.0.0.0/16) into AWS, thereby preserving the private IP addresses for application servers. AWS Transit Gateway (Option A) is a hub that connects multiple VPCs and on-premises networks but requires VPN or Direct Connect attachments; it does not directly provide IP preservation. VPC Peering (Option B) connects VPCs within AWS, not on-premises networks. AWS Direct Connect (Option D) provides a dedicated private connection but does not inherently preserve IP addresses; it can be used with VPN to achieve IP preservation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
