CV0-004 Practice Question: A cloud architect is designing a disaster…
A cloud architect is designing a disaster recovery plan. Which TWO strategies ensure minimal data loss?
⚠ Common exam trap
Many exam-takers confuse asynchronous replication (which has a non-zero RPO) with synchronous replication (which has zero RPO), or they mistakenly believe that daily backups in the same data center are sufficient for disaster recovery, ignoring the need for geographic separation and low RPO.
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
✓
Synchronous replication across regions
Synchronous replication across regions (B) ensures that every write is committed to both the primary and secondary sites before acknowledging the client, resulting in zero data loss (RPO=0) in the event of a failover. Application-level multi-region writes (D) allow the application to write directly to multiple independent databases simultaneously, ensuring that all regions have the latest data and no data is lost if one region fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Daily backups stored in the same data center
Why it's wrong here
Daily backups risk losing up to 24 hours of data and are in the same location.
- ✓
Synchronous replication across regions
Why this is correct
Synchronous replication guarantees zero data loss as data is written to both sites before acknowledgment.
- ✗
Asynchronous replication with hourly snapshots
Why it's wrong here
Asynchronous replication may lose up to an hour of data; RPO is higher.
- ✓
Application-level multi-region writes
Why this is correct
Application-level writes to multiple regions ensure data is consistent across locations with minimal latency.
- ✗
Periodic manual exports to on-premises storage
Why it's wrong here
Manual exports are infrequent and prone to human error, resulting in significant data loss.
