問題文
A team turns on local Autonomous Data Guard for an Autonomous AI Database Serverless instance in OD@GCP and reports to the risk committee that the database now survives the loss of a zone. What should the architect check before that sentence goes into the report?
選択肢
- Which database version the instance runs, because the published region list offers the dual-zone configuration to the later version of the software and leaves the earlier version in a single-zone region until an upgrade of the instance that the team schedules for later.
- Whether a cross-region peer exists as well, because the local standby moves to a second zone and stays there once the instance holds a peer of that kind at the version of the software it runs today.
- Which zone configuration the published region list gives for the region of that instance, because the local standby of the database lands in a second zone in the regions marked dual-zone and sits beside the primary inside a single-zone region.
- Whether the backup-based form of recovery was replaced, because the local standby follows the zone of the backup-based copy that the instance holds and keeps in this region under the plan set by the team today.
