The correct answer is to implement synchronous replication, a warm standby in another region, and active-passive failover with automated DNS. Synchronous replication ensures a recovery point objective of 15 minutes by writing data to both primary and secondary sites simultaneously, preventing any data loss. A warm standby, with pre-provisioned but idle resources, allows failover within the 1-hour recovery time objective, while active-passive configuration with automated DNS routing minimizes transition time by redirecting traffic only when a failure is detected. On the CompTIA Cloud+ CV0-004 exam, this scenario tests your ability to balance cost and performance for low RTO and RPO requirements—a common trap is choosing a cold standby or asynchronous replication, which would fail the RPO or RTO targets. Remember the mnemonic “SWAP”: Synchronous replication, Warm standby, Active-passive, and automated DNS for fast failover.
CV0-004 Operations and Support Practice Question
This CV0-004 practice question tests your understanding of operations and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 architect is designing a disaster recovery plan for a critical application. The application runs on virtual machines in a public cloud. The recovery time objective (RTO) is 1 hour, and the recovery point objective (RPO) is 15 minutes. Which three strategies should the architect implement? (Select THREE).
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement active-passive failover with automated DNS.
Synchronous replication provides low RPO; warm standby ensures quick failover within RTO; active-passive with automated DNS reduces transition time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Implement active-passive failover with automated DNS.
Why this is correct
Correct. Automated DNS failover speeds up recovery, helping achieve the RTO.
Related concept
Read the scenario before looking for a memorised answer.
✓
Use synchronous replication to a secondary region.
Why this is correct
Correct. Synchronous replication provides near-zero RPO, meeting the 15-minute requirement.
Related concept
Read the scenario before looking for a memorised answer.
✗
Take daily snapshots of the VMs.
Why it's wrong here
Daily snapshots exceed the 15-minute RPO.
✗
Use asynchronous replication with a 10-minute lag.
Why it's wrong here
Asynchronous replication may meet RPO but does not guarantee automated failover to meet RTO; it is less reliable than synchronous.
✓
Maintain a warm standby in another region.
Why this is correct
Correct. A warm standby can be activated quickly to meet the 1-hour RTO.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
