Question

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?

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.

Answer 1

C

Step-by-step explanation:

Golden Gate Gate Cloud Service is more appropriate as it is a cloud based replication service with sub-second latency. This minimises downtime for the customer as Golden Gate Cloud can be used immediately after a fault, as the database will be fully replicated up to the moment of the fault occurring.
