The answer is AWS Site-to-Site VPN. This service creates an encrypted tunnel between your on-premises network and a virtual private gateway in your VPC, allowing you to extend your on-premises network to AWS and preserve private IP addresses by routing traffic over the VPN without any address translation. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of hybrid networking—specifically how to maintain IP continuity during migration without reconfiguring application servers. A common trap is choosing AWS Direct Connect, which provides a dedicated physical link but does not inherently preserve IPs unless combined with a VPN or BGP routing; another is VPC Peering, which only connects VPCs, not on-premises networks. Memory tip: think of Site-to-Site VPN as a secure tunnel that keeps your IPs intact—like a private bridge that doesn’t change your house number.
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 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
Option A is correct because AWS Site-to-Site VPN creates an encrypted connection between on-premises and VPC. Option B is wrong because VPC Peering does not extend on-premises network. Option C is wrong because AWS Transit Gateway connects VPCs and on-premises, but VPN is the actual mechanism to extend IPs. Option D is wrong because Direct Connect provides dedicated connection but does not inherently preserve IPs.
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 Transit Gateway
Why it's wrong here
Transit Gateway is a hub, but the connection to on-premises still requires VPN or Direct Connect.
✗
VPC Peering
Why it's wrong here
VPC Peering connects VPCs, not on-premises to AWS.
✓
AWS Site-to-Site VPN
Why this is correct
Site-to-Site VPN extends on-premises network to VPC, preserving IP addresses.

✗
AWS Direct Connect
Why it's wrong here
Direct Connect provides physical connection but does not automatically preserve IP addresses; routing must be configured.
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.
