The answer is to create a cross-Region read replica and promote it during a disaster, or to use a Multi-AZ deployment with a standby in another region. Both solutions achieve sub-5 second RPO and sub-1 minute RTO for RDS PostgreSQL because they leverage synchronous or near-synchronous replication across AWS regions, minimizing data loss and enabling rapid failover. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of the critical distinction between synchronous replication (low RPO/RTO) and asynchronous methods like snapshot copy or automated backups, which introduce higher latency. A common trap is assuming cross-Region snapshot copy meets aggressive RPO requirements—it does not, as snapshots are taken periodically. For memory, remember that “replicas and standby” are your low-latency friends, while “snapshots and backups” are for higher RPO tolerance.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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 company is designing a disaster recovery strategy for a critical application running on Amazon RDS for PostgreSQL. The primary database is in us-east-1. The company needs a Recovery Point Objective (RPO) of less than 5 seconds and a Recovery Time Objective (RTO) of less than 1 minute. Which TWO solutions meet these requirements? (Choose TWO.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a Multi-AZ deployment with a standby in a different AWS Region.
Option A is correct because Multi-AZ with a standby in another region (cross-region) provides synchronous replication with low RPO/RTO. Option D is correct because a read replica in another region can be promoted quickly. Option B is wrong because cross-region snapshot copy has higher RPO. Option C is wrong because automated backups have higher RPO. Option E is wrong because DMS has higher latency.
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.
✗
Use AWS Database Migration Service (DMS) for continuous replication.
Why it's wrong here
DMS replication can have lag greater than 5 seconds.
✓
Configure a Multi-AZ deployment with a standby in a different AWS Region.
Why this is correct
Cross-region Multi-AZ provides synchronous replication and fast failover.
Clue confirmation

✓
Create a cross-Region read replica and promote it during a disaster.
Why this is correct
Read replica replication lag is typically sub-second.

✗
Take daily snapshots and copy them to another Region.
Why it's wrong here
Snapshots have RPO of up to 24 hours.
✗
Enable automated backups with a retention period of 35 days.
Why it's wrong here
Automated backups have RPO of up to 5 minutes, not seconds.
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.

Variation 1. A company is designing a disaster recovery strategy for a multi-tier application hosted on AWS. The application uses Amazon RDS for MySQL with Multi-AZ deployment. The Recovery Time Objective (RTO) is 15 minutes and Recovery Point Objective (RPO) is 1 hour. Which solution meets these requirements with the LEAST operational overhead?
hard
✓ A.Configure a Cross-Region Read Replica of the RDS instance and promote it during disaster.
B.Use AWS Database Migration Service (DMS) to continuously replicate data to a standby RDS instance in another region.
C.Take automated snapshots every hour and copy them to another region. Restore from snapshot during disaster.
D.Use RDS Multi-AZ in a different region.
Why A: Using Cross-Region Read Replicas for RDS MySQL allows automatic replication with an RPO of seconds and failover in minutes, meeting the requirements with minimal overhead.
