- A
Disable automated backups and rely on manual snapshots taken during off-peak hours.
Why wrong: Disabling automated backups is not recommended for production environments as it increases the risk of data loss.
- B
Create a read replica and configure automated backups on the replica.
Offloading backups to a read replica ensures that backup operations do not affect the primary instance's performance.
- C
Increase the DB instance size to improve backup performance.
Why wrong: Increasing instance size may speed up backups but does not directly minimize the performance impact on the workload; it also increases costs.
- D
Move the backup window to a time when the workload is lowest.
Why wrong: Changing the backup window does not reduce the duration of the backup or its impact on performance; it only shifts the impact to a different time.
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. 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 company is running a production Amazon RDS for MySQL DB instance. The database size is 500 GB and the workload is write-heavy. The team notices that the automated backups are taking longer than expected and are impacting the performance during the backup window. Which action should be taken to minimize the performance impact?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Create a read replica and configure automated backups on the replica.
Option D is correct because creating a read replica and taking backups from it offloads the backup load from the primary instance. Option A is wrong because disabling backups is risky for production. Option B is wrong because it affects the start time but not the performance impact. Option C is wrong because increasing instance size may reduce backup duration but does not directly minimize the performance impact; it also adds cost.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
