SAP-C02 Rehost (Lift and Shift) Practice Question
A company is migrating a legacy application from an on-premises data center to AWS. The application uses a proprietary network protocol that is not supported by AWS Application Migration Service. What should the company do to migrate this application?
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
✓
Perform a manual rehost migration using Amazon EC2 and custom AMIs.
D is correct because performing a manual rehost migration using Amazon EC2 and custom AMIs allows the company to migrate the legacy application without depending on AWS Application Migration Service (MGN), which does not support the proprietary protocol. This approach replicates the on-premises environment in AWS. A is incorrect because refactoring the application to use standard protocols would require significant code changes and is not necessary for migration. B is incorrect because the 7 Rs strategy is a framework for evaluating migration approaches, not a specific solution to the protocol incompatibility. C is incorrect because AWS Application Migration Service with a network bridge appliance does not address the lack of support for the proprietary protocol.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Refactor the application to use standard protocols before migration.
Why it's wrong here
Refactoring the application to use standard protocols would require rewriting core networking logic, which contradicts the goal of a direct migration—the stem specifies migrating the legacy application, not redeveloping it. This option is tempting because refactoring is a common strategy when an application is incompatible with a target environment, and it would be correct if the company intended to modernise the application rather than preserve its existing proprietary protocol behaviour.
- ✗
Use the 7 Rs migration strategy to evaluate other options.
Why it's wrong here
The 7 Rs is a conceptual framework, not a solution.
- ✗
Use AWS Application Migration Service with a network bridge appliance.
Why it's wrong here
MGN still requires supported network protocols.
- ✓
Perform a manual rehost migration using Amazon EC2 and custom AMIs.
Why this is correct
Manual rehost bypasses MGN's limitations.
