The answer is to switch to synchronous replication. This is the most appropriate improvement because asynchronous replication introduces a lag between the primary and replica sites, which can lead to data inconsistency during a failover event—any transactions committed after the last replication cycle are lost. For disaster recovery, synchronous replication guarantees that data is written to both sites before the transaction is acknowledged, ensuring full consistency at the cost of added latency. On the ISC2 Certified in Cybersecurity CC exam, this concept tests your understanding of the trade-off between data integrity and performance in DR strategies; a common trap is choosing asynchronous replication for its lower latency without recognizing the risk of data loss. Remember the memory tip: “Sync for safety, Async for speed”—when the exam asks about consistency during failover, always prioritize synchronous replication.
ISC2 CC Business Continuity, DR & Incident Response Practice Question
This CC practice question tests your understanding of business continuity, dr & incident response. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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.
Exhibit
DR Drill Report:
- Network failover: 5 minutes (success)
- Database failover: FAILED (inconsistent data)
- Root cause: Asynchronous replication lag caused data mismatch
Refer to the exhibit. Based on the report, which improvement is most appropriate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Switch to synchronous replication
Asynchronous replication can lead to data inconsistency during failover. Switching to synchronous replication ensures data consistency at the cost of some latency.
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.
✗
Increase backup frequency
Why it's wrong here
Backups alone do not prevent inconsistency during failover.
✗
Reduce network failover time
Why it's wrong here
Network failover already succeeded; the issue is data consistency.
✗
Implement load balancing
Why it's wrong here
Load balancing does not address replication consistency.
✓
Switch to synchronous replication
Why this is correct
Synchronous replication guarantees transaction consistency across sites.

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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
