1Z0-1072-26 Database Practice Question
You have configured an Oracle Data Guard association between a primary Autonomous Database and a standby Autonomous Database. What happens to the standby database if the primary database experiences an unplanned regional outage?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
You can perform a failover operation in the OCI Console to promote the standby database to primary.
In Autonomous Database Data Guard, if the primary goes down, you can manually initiate a role transition (switchover/failover) or rely on automatic failover depending on the configuration, promoting the standby to primary.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The standby database remains permanently read-only and cannot accept write transactions.
Why it's wrong here
A standby database can be promoted to become the primary read-write database.
- ✗
The standby database automatically destroys itself and reprovisions in the primary region.
Why it's wrong here
Standby databases do not destroy themselves during outages.
- ✓
You can perform a failover operation in the OCI Console to promote the standby database to primary.
Why this is correct
Manual or automated failover promotes the standby database to accept read-write traffic.
- ✗
Data Guard automatically switches back to the primary database via split-brain prevention algorithms.
Why it's wrong here
Automatic switchback to a failed primary does not occur without administrative intervention.
