Question 430
An engineering organization has identified this operational requirement, the decisive constraint is: A legacy Linux application needs a rollback window because licensing behavior on EC2 is uncertain. What should the architect implement?
Explanation
Correct Answer
Test the licensing behavior in a launched migration test and preserve the source rollback path. Validation before production cutover reduces irreversible migration failures.
Incorrect Answers
Retain or redesign the hardware-dependent component rather than forcing an MGN rehost would address a different requirement: A workload must preserve unsupported local hardware dongles and cannot run in EC2. Replicating server disks does not make unsupported physical dependencies cloud-compatible.
For the separate situation A Windows and Linux fleet must move from VMware to EC2 with minimal application rewrites, Use AWS Application Migration Service for continuous block-level replication and planned cutover could be useful. MGN supports lift-and-shift server migration with replication and test launches.
Keep continuous MGN replication and coordinate the cutover window and final launch solves the related scenario A server migration requires short downtime and ongoing source-write replication until the final launch; incremental block replication minimizes changes left to transfer at cutover.
