DOP-C02 Resilient Cloud Solutions Practice Question
This DOP-C02 practice question tests your understanding of resilient cloud solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 deploying a critical web application on AWS and needs to ensure high availability and disaster recovery across multiple AWS Regions. The application uses an Application Load Balancer (ALB) in the primary Region and an Amazon RDS Multi-AZ DB instance. Which TWO actions should the company take to 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
✓
Use AWS Global Accelerator with endpoint groups in multiple Regions.
Option B is correct because AWS Global Accelerator provides static IP addresses and routes traffic to the optimal endpoint across regions, supporting active-passive failover. Option E is correct because Route 53 health checks can monitor the primary ALB and automatically failover to a secondary ALB in another region. Option A is wrong because RDS Multi-AZ only provides high availability within a single region, not cross-region disaster recovery. Option C is wrong because Auto Scaling groups are for scaling within a region, not cross-region failover. Option D is wrong because CloudFront is a CDN, not designed for regional failover routing.
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.
✗
Configure an Amazon RDS Multi-AZ deployment in a secondary Region.
Why it's wrong here
Multi-AZ is single-region only.
✗
Set up Amazon CloudFront with multiple origins pointing to each Region's ALB.
Why it's wrong here
CloudFront is not designed for active-passive failover routing.
✗
Create an Auto Scaling group in the secondary Region that automatically scales up when the primary fails.
Why it's wrong here
Auto Scaling does not handle failover routing.
✓
Use AWS Global Accelerator with endpoint groups in multiple Regions.
Why this is correct
Global Accelerator provides cross-region failover.

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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
