DEA-C01 Data Store Management Practice Question
Which THREE steps are recommended for migrating an on-premises Oracle database to Amazon RDS for Oracle with minimal downtime? (Choose 3.)
⚠ Common exam trap
It's easy for candidates to think disabling archiving simplifies the migration, but they miss that CDC requires archived logs for minimal downtime, and they may also assume a full load alone is sufficient without realizing it forces a longer outage to ensure data consistency.

Correct answer & explanation
✓
Set up a VPN or Direct Connect between on-premises and AWS
Establishing a VPN or Direct Connect provides a secure, private, and low-latency network connection between the on-premises environment and AWS. This is essential for minimizing downtime during a migration, as it ensures reliable and fast data transfer for both the initial full load and ongoing replication, reducing the risk of network interruptions that could extend the migration window.
