The correct answer is to deploy an Amazon Aurora Global Database with a secondary region and use a Multi-AZ RDS instance with synchronous replication. This combination meets the stringent disaster recovery requirements of a 15-minute RTO and 1-minute RPO because Multi-AZ RDS provides near-zero data loss through synchronous standby replicas, while Aurora Global Database enables fast, managed failover to a remote region with typical RTO under a minute and RPO of seconds. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your ability to distinguish between synchronous replication for low RPO and asynchronous or snapshot-based methods that fail the time constraints. A common trap is choosing cross-region snapshot restore, which takes far longer than 15 minutes, or assuming a single Multi-AZ deployment alone covers cross-region recovery. Remember the key pairing: Multi-AZ for local, synchronous durability, and Aurora Global for cross-region, low-latency failover—think “local sync, global fast.”
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new 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 architecture for a critical application. The primary region runs on Amazon EC2 with an RDS database. The recovery time objective (RTO) is 15 minutes, and recovery point objective (RPO) is 1 minute. Which TWO steps should be taken to meet these objectives?
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 RDS Multi-AZ in the primary region.
Options A and C are correct. A Multi-AZ RDS instance with synchronous replication provides an RPO of seconds and can failover quickly. An Aurora Global Database with a secondary region also provides low RPO and RTO. Option B is wrong because cross-region snapshot restore takes longer than 15 minutes. Option D is wrong because RTO would be too high. Option E is wrong because RTO includes database failover.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Deploy an Amazon Aurora Global Database with a secondary region.
Why this is correct
Aurora Global Database provides low RPO and RTO across regions.

✗
Pre-warm a standby EC2 instance in the DR region.
Why it's wrong here
EC2 warm standby alone does not address database failover.
✗
Take hourly snapshots of RDS and copy them to the DR region.
Why it's wrong here
Snapshot restore takes more than 15 minutes.
✗
Use Amazon S3 Cross-Region Replication for application data.
Why it's wrong here
S3 CRR is for object storage, not database.
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.
