Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Cosmos DB Change Feed processor
Why this is correct
The change feed allows reading inserts and updates to migrate data live without downtime.
- ✗
Azure Data Factory tumbling window triggers over Blob Storage
Why it's wrong here
Data resides in Cosmos DB, not blob storage, and change feed is the native real-time mechanism.
- ✗
SQL Server Integration Services (SSIS) file import
Why it's wrong here
SSIS is not native to Cosmos DB live container data migration.
- ✗
Taking a manual offline portal backup and restoring to a new account
Why it's wrong here
Restoring accounts takes the application offline and is intended for disaster recovery, not live container migration.
