Question 690
A deployed environment still does not meet the original requirement: A source MySQL workload must migrate to Amazon RDS MySQL without an engine conversion project. Which underlying cause should be investigated first?
Explanation
Correct Answer
This is the technical design error aligned with the unmet requirement. Homogeneous migrations usually focus on data replication, compatibility details and cutover rather than engine-language rewrite. The appropriate correction is: Prefer a supported homogeneous DMS migration or native replication pattern with CDC where suitable. The control should then be tested by verifying that Destination table state stays synchronized and the application passes a reversible cutover test.
Incorrect Answers
Source virtualization format was mistaken for a guarantee of target runtime compatibility. The stated evidence instead indicates: Complex heterogeneous schema conversion was selected unnecessarily for a same-engine migration.
Replicating table data alone does not translate incompatible source SQL constructs. The stated evidence instead indicates: Complex heterogeneous schema conversion was selected unnecessarily for a same-engine migration.
The migration plan assumes a new AWS Snowball Edge device can still be ordered even though new-customer ordering is unavailable. The stated evidence instead indicates: Complex heterogeneous schema conversion was selected unnecessarily for a same-engine migration.
