SOA-C02 Reliability and Business Continuity Practice Question
This SOA-C02 practice question tests your understanding of reliability and business continuity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 wants to ensure that its Amazon RDS database can withstand the loss of an entire Availability Zone. Which feature should the SysOps administrator enable?
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.
Option B is correct: Multi-AZ deployment creates a standby in a different AZ; if the primary AZ fails, RDS automatically fails over to the standby. Option A is incorrect because read replicas can be in a different AZ but are not used for automatic failover. Option C is incorrect because manual snapshots require manual restoration. Option D is incorrect because automated backups are stored in S3 and do not provide automatic failover.
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.

Why it's wrong here
Automated backups are for point-in-time recovery, not failover.
✓
Enable Multi-AZ deployment.
Why this is correct
Multi-AZ provides automatic failover to a standby in another AZ.

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.
