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 replicates data at the block level across heterogeneous database engines (e.g., PostgreSQL to Oracle).
Why it's wrong here
Data Guard works strictly between Oracle database instances.
- ✓
It allows read-only queries to run on the physical standby database while real-time redo apply is active.
Why this is correct
Active Data Guard enables read-only workloads on the standby database.
- ✗
It automatically shards the primary database tables across multiple standby regions.
Why it's wrong here
Sharding is handled by Oracle Sharding, not Data Guard.
- ✗
It allows read-write operations on the standby database while synchronizing with the primary.
Why it's wrong here
Standby databases remain read-only; write operations are not permitted during active sync.
