Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It automatically provisions a standby database and handles failover and switchover operations to ensure high availability.
Why this is correct
Autonomous Data Guard automates standby provisioning and failover workflows for maximum availability.
- ✗
It allows read-write operations simultaneously on both primary and standby databases across regions.
Why it's wrong here
Data Guard standby databases operate in read-only or snapshot mode, not concurrent read-write across regions.
- ✗
It automatically shards tables across two different cloud regions to speed up write operations.
Why it's wrong here
Data Guard is for replication and high availability, not horizontal database sharding.
- ✗
It reduces cloud storage billing by compressing redundant backup blocks on the standby instance.
Why it's wrong here
Compression is a database feature, but Data Guard's main purpose is disaster recovery and high availability.
