This CV0-004 practice question tests your understanding of operations and support. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A cloud engineer is designing a disaster recovery plan for a critical application. The application requires a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 1 hour. Which replication strategy should be used?
Asynchronous replication with snapshots every 30 minutes.
Snapshots every 30 minutes meet RPO of 1 hour; RTO achieved by failover.
Daily backups stored in a different region.
Why wrong: RPO of 24 hours does not meet 1 hour requirement.
No replication; rely on infrastructure rebuild.
Why wrong: Would not meet RTO or RPO.
Synchronous replication between two regions.
Why wrong: Overkill for 1-hour RPO; high cost.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Asynchronous replication with snapshots every 30 minutes.
Asynchronous replication with snapshots every 30 minutes meets the RPO of 1 hour because data loss is limited to at most 30 minutes of changes, which is within the 1-hour window. The RTO of 15 minutes is achievable because the replicated data is readily available in the secondary region, allowing for rapid failover without the delay of restoring from backups.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Asynchronous replication with snapshots every 30 minutes.
Why this is correct
Snapshots every 30 minutes meet RPO of 1 hour; RTO achieved by failover.
Related concept

Daily backups stored in a different region.
Why it's wrong here
RPO of 24 hours does not meet 1 hour requirement.
No replication; rely on infrastructure rebuild.
Why it's wrong here
Would not meet RTO or RPO.
Synchronous replication between two regions.
Why it's wrong here
Overkill for 1-hour RPO; high cost.
Common exam traps
CompTIA often tests the misconception that synchronous replication is always the best choice for disaster recovery, but the trap here is that synchronous replication over long distances introduces unacceptable latency, making it unsuitable for applications with strict performance requirements, while asynchronous replication with appropriate snapshot intervals can meet moderate RPO/RTO goals without performance degradation.
Detailed technical explanation
Asynchronous replication writes data to the primary site first and then replicates to the secondary site without waiting for acknowledgment, which minimizes latency impact on the application. Snapshot intervals of 30 minutes ensure that the maximum data loss (RPO) is capped at 30 minutes, well within the 1-hour requirement. In practice, this strategy is often implemented using technologies like AWS RDS cross-Region read replicas with automated backups or Azure SQL Database active geo-replication with point-in-time restore, where failover can be initiated within minutes.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
