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.
Which TWO steps should a SysOps administrator take to ensure that an RDS for MySQL instance can withstand an Availability Zone failure? (Choose 2)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Multi-AZ deployment.
Options A and D are correct. Multi-AZ creates a standby in another AZ, and automated backups with PITR allow recovery to a point in time. Option B is wrong because read replicas are for read scaling, not failover. Option C is wrong because provisioned IOPS improve performance, not availability. Option E is wrong because deletion protection prevents accidental deletion, not AZ failure.
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 Multi-AZ deployment.
Why this is correct
Multi-AZ automatically provisions a standby instance in a different AZ and handles failover automatically.
Related concept
Read the scenario before looking for a memorised answer.
✗
Create a read replica in a different AZ.
Why it's wrong here
Read replicas are for offloading read traffic and do not provide automatic failover for writes.
✓
Enable automated backups with a short retention period.
Why this is correct
Automated backups enable point-in-time recovery, which can restore the database to a specific time, reducing data loss.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable deletion protection on the DB instance.
Why it's wrong here
Deletion protection prevents accidental deletion but does not protect against an AZ failure.
✗
Enable provisioned IOPS for the DB instance.
Why it's wrong here
Provisioned IOPS improve I/O performance but do not affect availability.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
