Quick Answer
The answer is Rehost, also known as lift-and-shift, as it represents the fastest and lowest risk migration strategy among the 7 Rs. This approach is correct because it involves moving the application to AWS EC2 with zero code changes, preserving the existing tightly coupled components and handling unpredictable traffic without introducing new failure points during migration. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your ability to distinguish between migration strategies under constraints of speed and risk; a common trap is choosing Replatform because it sounds like a middle ground, but Replatform requires modifications that increase both time and risk. Remember the memory tip: if the goal is to move fast and break nothing, you lift and shift first, then refactor later—think “Rehost for the rush, refactor for the future.”
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 plans to migrate a legacy on-premises web application to AWS using the 7 Rs (Rehost, Replatform, etc.). The application has tightly coupled components and unpredictable traffic. The team wants to minimize migration risk and time. Which migration strategy should they use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Replatform
Why wrong: Replatform requires some application modifications, increasing time and risk.
Rehost (lift-and-shift)
Rehost migrates without changes, minimizing risk and time.
Repurchase
Why wrong: Repurchase replaces the application with a SaaS product, which is a different approach.
Retire
Why wrong: Retire means decommissioning, not migrating.

Correct answer & explanation
Rehost (lift-and-shift)
Rehost (lift-and-shift) is the fastest and lowest-risk migration strategy because it does not require code changes. It allows the company to move the application as-is to EC2, then refactor later. Option A (Replatform) involves some modifications. Option C (Retire) is for decommissioning. Option D (Repurchase) means replacing with SaaS.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Replatform
Why it's wrong here
Replatform requires some application modifications, increasing time and risk.
Rehost (lift-and-shift)
Why this is correct
Rehost migrates without changes, minimizing risk and time.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
