DEA-C01 Data Operations and Support Practice Question
This DEA-C01 practice question tests your understanding of data 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 data engineer is designing a disaster recovery strategy for an Amazon RDS for MySQL database with Multi-AZ deployment. Which THREE actions should the engineer take to meet a Recovery Point Objective (RPO) of 5 minutes and a Recovery Time Objective (RTO) of 15 minutes? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable automated backups with a retention period of 7 days.
Options A, B, and D provide fast failover and minimal data loss. Option A ensures automatic failover to a standby in another AZ. Option B (cross-region read replica) can be promoted in minutes. Option D (automated backups) provide point-in-time recovery. Option C (snapshots to S3) is slower and may not meet RTO. Option E (Single-AZ) increases risk.
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.
✓
Enable automated backups with a retention period of 7 days.
Why this is correct
Automated backups allow point-in-time recovery within the retention window, helping meet RPO.
Related concept
Read the scenario before looking for a memorised answer.
✓
Create a cross-region read replica to another AWS region.
Why this is correct
A cross-region replica can be promoted to a primary database quickly, meeting RTO and RPO.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure the DB instance to be Single-AZ for simplicity.
Why it's wrong here
Single-AZ does not provide high availability and would increase RTO.
✗
Export automated snapshots to an S3 bucket in a different region.
Why it's wrong here
Restoring from a snapshot takes longer than promoting a read replica, likely not meeting RTO.
✓
Enable Multi-AZ deployment for automatic failover.
Why this is correct
Multi-AZ provides automatic failover to a standby in another AZ, reducing 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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
