AWS Application Migration Service (AWS MGN) is the correct choice because it is specifically built to automate lift-and-shift migrations of on-premises VMware virtual machines directly to Amazon EC2. The service works by continuously replicating your source VMware VMs to a staging area in your AWS account, then automatically converting and launching those instances on EC2 with minimal downtime, handling the underlying driver and boot configuration changes for you. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of which service handles heterogeneous migrations—meaning it can migrate from any source (including VMware) to AWS without needing to refactor the application. A common trap is confusing AWS MGN with AWS Server Migration Service (SMS), which is older and less automated; remember that MGN is the modern, fully managed replacement. Memory tip: think "MGN = Migrate, Go, Now" for the fastest path from VMware to EC2.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. 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 wants to migrate their on-premises VMware virtual machines to Amazon EC2. Which AWS service simplifies this lift-and-shift migration?
Why wrong: Snowball handles bulk data transfer — it doesn't migrate running VMs or replicate server states to EC2.
B
AWS Application Migration Service (AWS MGN)
AWS MGN continuously replicates on-premises servers (physical, virtual, or cloud) to AWS, enabling non-disruptive testing and cutover for lift-and-shift migrations to EC2.
C
AWS Database Migration Service
Why wrong: DMS migrates databases — it doesn't migrate full server workloads including OS and applications to EC2.
D
Amazon EC2 Import/Export
Why wrong: EC2 Import is the older VM Import/Export feature — AWS MGN is the current recommended service for server migrations.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Application Migration Service (AWS MGN)
AWS Application Migration Service (AWS MGN) is the correct choice because it is specifically designed to simplify and automate the lift-and-shift migration of on-premises VMware virtual machines to Amazon EC2. It continuously replicates source servers (including VMware VMs) to a staging area in AWS, then automatically converts and launches the instances on EC2, minimizing downtime and manual effort.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
EC2 Import is the older VM Import/Export feature — AWS MGN is the current recommended service for server migrations.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS MGN with the older EC2 Import/Export service, mistakenly thinking the legacy tool is sufficient for a modern lift-and-shift migration, but EC2 Import/Export requires manual steps and does not support continuous replication or automated conversion.
Detailed technical explanation
How to think about this question
AWS MGN uses block-level replication to continuously copy data from the source VMware VM to a staging area in AWS, leveraging the AWS Replication Agent installed on the source. During cutover, it automatically converts the replicated data into an EC2 instance with the appropriate instance type, storage, and networking, using AWS-provided drivers and boot configuration. In real-world scenarios, this allows for near-zero downtime migrations even for large-scale VMware environments, as the replication can run for weeks before a final cutover.

TExam Day Tips
→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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
