Oracle Cloud Infrastructure 2019 Architect Associate — Question 11

A customer wants to migrate to Autonomous Database (ADB) but only allows for a very small window of downtime. Golden Gate was advised to be used during the migration. For maximum reassurance of their end-users, the customer also would like to use Golden Gate as a fall-back scenario for the first 6 months after the migration. If customers complain, the on-premise data can be synchronised with the ADB Instance for a switch back.
Which statement about the migration using Golden Gate is correct?

Answer options

• A. Migration to ADB is not possible using Golden Gate because the apply-process cannot be installed on ADB.
• B. Only the migration to ADB is possible from an on-premise installation of Golden Gate.
• C. Golden Gate on premise is not certified with ADB because Golden Gate Cloud Service exists for this.
• D. The fallback scenario is not possible using Golden Gate because the capture-process cannot be installed on ADB.
• E. The described scenario is correct, can be used for migration and fallback scenarios.

Correct answer: B

Explanation

The correct answer is B because migrating to ADB from an on-premise installation of Golden Gate is indeed possible. Options A and D incorrectly state limitations regarding the apply-process and capture-process, while C falsely claims that Golden Gate on-premise is not certified for ADB without acknowledging the migration possibility. Option E misrepresents the scenario by suggesting that all parts of it are feasible.
