DOP-C02 Resilient Cloud Solutions Practice Question

Q: How is Resilient Cloud Solutions tested on the DOP-C02 exam?

Resilient Cloud Solutions — This question tests Resilient Cloud Solutions — Read the scenario before looking for a memorised answer..

Q: What is the correct answer to this Resilient Cloud Solutions DOP-C02 question?

The correct answer is: Use a warm standby with a minimal environment in the DR region, using DynamoDB Global Tables and S3 CRR, with Auto Scaling to scale up on failover. — Option C is correct because the application is stateless and uses S3 and DynamoDB. S3 Cross-Region Replication (CRR) can achieve near-real-time replication (RPO < 1 minute). DynamoDB Global Tables provide multi-region active-active replication with sub-second RPO. A pre-configured standby in the DR region (with scaled-down resources) can be quickly scaled up (within RTO) using Auto Scaling and CloudFormation. Option A (pilot light) is less prepared; Option B (warm standby with full capacity) is more costly; Option D (multi-site active-active) is overkill and costly.

Q: Why do candidates get Resilient Cloud Solutions questions wrong on the DOP-C02 exam?

Identify which DOP-C02 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.

This DOP-C02 practice question tests your understanding of resilient cloud solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 DevOps engineer is designing a disaster recovery (DR) strategy for a stateless web application running on EC2 instances with an Application Load Balancer. The application stores data in Amazon S3 and uses a DynamoDB table for session data. The primary region is us-east-1 and the DR region is us-west-2. The RTO is 15 minutes and RPO is 1 minute. Which strategy is most cost-effective and meets the requirements?

Clue words in this question

A
Use a warm standby with a minimal environment in the DR region, using DynamoDB Global Tables and S3 CRR, with Auto Scaling to scale up on failover.
This balances cost and recovery time: replication ensures RPO, and minimal standby with Auto Scaling can scale within RTO.
B
Use a warm standby strategy with a scaled-down but fully functional environment in the DR region.
Why wrong: Warm standby is more expensive than needed; a minimal standby with Auto Scaling can meet RTO at lower cost.
C
Use a multi-site active-active strategy, running the application in both regions with a Route 53 latency-based routing.
Why wrong: Active-active is more expensive and complex; the RTO and RPO don't require it.
D
Use a pilot light strategy with CloudFormation templates to provision resources in the DR region on failure.
Why wrong: Pilot light requires provisioning core resources, but RTO of 15 minutes may be tight if provisioning takes time; also DynamoDB global tables are already active.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Use a warm standby with a minimal environment in the DR region, using DynamoDB Global Tables and S3 CRR, with Auto Scaling to scale up on failover.

Option C is correct because the application is stateless and uses S3 and DynamoDB. S3 Cross-Region Replication (CRR) can achieve near-real-time replication (RPO < 1 minute). DynamoDB Global Tables provide multi-region active-active replication with sub-second RPO. A pre-configured standby in the DR region (with scaled-down resources) can be quickly scaled up (within RTO) using Auto Scaling and CloudFormation. Option A (pilot light) is less prepared; Option B (warm standby with full capacity) is more costly; Option D (multi-site active-active) is overkill and costly.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

What to study next
