DBS-C01 Deployment and Migration Practice Question
A company wants to migrate a self-hosted MongoDB database to Amazon DocumentDB. They need to convert the schema. Which AWS service should they use?
⚠ Common exam trap
A common mix-up: candidates confuse AWS DMS as a full migration solution for heterogeneous databases, not realizing that DMS only handles data movement and relies on SCT for schema conversion when the source and target engines differ.
Answer choices
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
✓
AWS Schema Conversion Tool (SCT)
AWS Schema Conversion Tool (SCT) is the correct choice because it is specifically designed to convert database schemas from one engine to another, including from MongoDB to Amazon DocumentDB. SCT analyzes the source schema, identifies incompatible objects, and generates a target schema that is compatible with DocumentDB, handling data type mappings, index conversions, and other structural differences.
