SOA-C02 Reliability and Business Continuity Practice Question
This SOA-C02 practice question tests your understanding of reliability and business continuity. 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 SysOps administrator is designing a disaster recovery plan for a critical application hosted on AWS. The application runs on EC2 instances with data stored in an RDS MySQL database. The RPO must be less than 15 minutes, and the RTO must be less than 1 hour. Which solution meets these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use an RDS Multi-AZ DB Cluster deployment.
Option D is correct because Multi-AZ DB Cluster provides automatic failover with low RPO and RTO, and synchronous replication keeps data consistent. Option A is wrong because single-AZ with snapshots has an RPO of up to 5 minutes and RTO of several hours. Option B is wrong because Read Replicas are asynchronous, leading to potential data loss. Option C is wrong because Daily snapshots do not meet the 15-minute RPO.
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.
✗
Take daily snapshots of the RDS instance and copy them to another Region.
Why it's wrong here
Incorrect: Daily snapshots mean up to 24 hours of data loss, exceeding the 15-minute RPO.
✗
Use an RDS DB instance with a Multi-AZ standby and a cross-Region Read Replica.
Why it's wrong here
Incorrect: Multi-AZ failover is fast, but cross-Region replication is asynchronous; RPO may exceed 15 minutes.
✓
Use an RDS Multi-AZ DB Cluster deployment.
Why this is correct
Correct: Multi-AZ DB Cluster provides synchronous replication with automatic failover, meeting RPO <15min and RTO <1 hour.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use a single-AZ RDS instance with automated backups and point-in-time recovery.
Why it's wrong here
Incorrect: RPO can be up to 5 minutes but RTO is typically hours, not under 1 hour.
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 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.
