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 tasked with designing a disaster recovery strategy for an Amazon RDS for PostgreSQL database. The database is currently in us-east-1. The recovery point objective (RPO) is 5 seconds, and the recovery time objective (RTO) is 1 minute. 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
✓
Enable Multi-AZ deployment with automatic failover.
Option D is correct because Multi-AZ with automatic failover provides a standby in a different AZ within the same region, with RTO typically 1-2 minutes and RPO of seconds. Option A is wrong because cross-region read replicas have asynchronous replication with potential lag >5 seconds. Option B is wrong because snapshots have RPO of hours. Option C is wrong because single-AZ does 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.
✗
Create a cross-region read replica in us-west-2 and promote it during a disaster.
Why it's wrong here
Cross-region replication is asynchronous and may exceed 5 seconds RPO.
✗
Take daily automated snapshots and copy them to another region.
Why it's wrong here
Snapshots have RPO of up to 24 hours.
✓
Enable Multi-AZ deployment with automatic failover.
Why this is correct
Multi-AZ provides synchronous replication and fast failover.

Read the scenario before looking for a memorised answer.
✗
Deploy the database in a single AZ and use point-in-time recovery.
Why it's wrong here
PITR relies on backups, RTO is long.
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.
