DBS-C01 Deployment and Migration Practice Question
This DBS-C01 practice question tests your understanding of deployment and migration. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 deploying a new MySQL database on Amazon RDS. They need to ensure that the database is automatically backed up daily and retained for 30 days. Which TWO configurations should be set? (Choose 2)
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
✓
Set backup retention period to 30 days.
Option A is correct because setting the backup retention period to 30 days ensures that automated backups are retained for the required duration. Option B is correct because automated backups must be enabled for the retention period to take effect; without enabling automated backups, no automatic daily backups occur. Together, these two settings satisfy the requirement for daily automated backups retained for 30 days.
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
The trap here is that candidates often confuse the backup window (Option C) or Multi-AZ (Option D) as being required for backup retention, when in fact only enabling automated backups and setting the retention period are necessary; the backup window is optional and Multi-AZ is unrelated to backup retention.
Detailed technical explanation
How to think about this question
Amazon RDS automated backups are enabled by default when you create a DB instance, and they include transaction logs for point-in-time recovery within the retention period. The backup retention period can be set from 0 to 35 days; setting it to 30 days means RDS automatically takes a daily snapshot and retains transaction logs for the full 30 days, allowing restoration to any second within that window. Manual snapshots, in contrast, are retained indefinitely until explicitly deleted and do not count toward the automated backup retention limit.
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.
TExam Day Tips
- 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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
