DP-300 Practice Question: Plan and configure high availability and disaster recovery
Network Topology
Refer to the exhibit. An administrator wants to restore the primary database SalesDB to a point in time 2025-03-15T09:00:00Z. What is the impact on the geo-replication?
⚠ Common exam trap
Many exam-takers assume geo-replication is resilient to any restore operation, but point-in-time restore is a data-level operation that breaks the replication link, unlike a failover which preserves it.
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
✓
The geo-replication will be terminated, and the secondary will become a standalone database.
When you perform a point-in-time restore (PITR) on a primary database that is configured for geo-replication, the geo-replication link is broken. The secondary database becomes a standalone read-only database, and the primary is restored as a new database (typically with a name like SalesDB_restored or a specified name). This is because PITR creates a new database from backups, which cannot maintain the continuous replication stream required for geo-replication.
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 geo-replication will continue seamlessly after the restore.
Why it's wrong here
Geo-replication is disrupted when the primary database is restored to a different point.
- ✗
The restore will fail because the database is in a geo-replication relationship.
Why it's wrong here
Restore is allowed but will break replication.
- ✓
The geo-replication will be terminated, and the secondary will become a standalone database.
Why this is correct
Restoring the primary to a different point in time breaks the replication link.
- ✗
The secondary database will automatically be restored to the same point in time.
Why it's wrong here
The secondary is not automatically restored.
