PAS-C01 Migration Practice Question
A company is planning to migrate a critical application to AWS using the 7 Rs migration strategy. The application is currently running on a large VMware VM. Which THREE strategies are appropriate for this migration? (Choose three.)
⚠ Common exam trap
Many exam-takers confuse Retire with decommissioning an application that is still needed, or assume Retain is a valid migration strategy when the requirement is to move to AWS.

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
✓
Rehost: Use AWS VM Import/Export to migrate the VM to EC2
Rehost (A) is appropriate because AWS VM Import/Export allows you to migrate VMware VMs directly to Amazon EC2 as AMIs, enabling a lift-and-shift migration with minimal changes. This is a core 7 Rs strategy for moving existing virtualized workloads to AWS.
