Correct answer & explanation
✓
Use AWS Elastic Disaster Recovery to replicate the on-premises servers to a staging area and launch test instances in a sandbox VPC.
AWS Elastic Disaster Recovery (AWS DRS) is the most cost-effective approach for testing SAP migration because it continuously replicates on-premises servers to a staging area with minimal resources, and allows launching test instances in an isolated sandbox VPC without affecting the source environment. This incurs low costs since staging resources are minimal and test instances are only launched temporarily. Option A is less cost-effective because DMS only handles database replication, not the full SAP system (OS, application, etc.), and a separate RDS instance still incurs costs. Option C is expensive as it requires provisioning full production-sized infrastructure. Option D is incorrect because Migration Hub is a tracking service and does not provide a sandbox for testing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Database Migration Service (AWS DMS) to continuously replicate the database to a smaller RDS instance for testing.
Why it's wrong here
AWS DMS replicates databases but does not test the entire SAP application stack.
- ✓
Use AWS Elastic Disaster Recovery to replicate the on-premises servers to a staging area and launch test instances in a sandbox VPC.
Why this is correct
AWS Elastic Disaster Recovery provides a cost-effective way to test migration with non-production instances.
- ✗
Provision a full production-sized infrastructure in a separate AWS account and use AWS DMS to replicate the database.
Why it's wrong here
Full production-sized infrastructure is costly for a test environment.
- ✗
Use AWS Migration Hub to track the migration progress and perform a trial migration using AWS CloudFormation templates.
Why it's wrong here
AWS Migration Hub tracks but does not provide a sandbox environment for testing.
