The correct three steps are deploying worker nodes across multiple Availability Zones, using Pod Disruption Budgets, and configuring cluster auto scaling. This combination directly addresses the need for EKS multi-AZ high availability by ensuring that if an entire AZ fails, the application continues running on nodes in other zones, while Pod Disruption Budgets guarantee a minimum number of pods remain operational during voluntary disruptions like rolling updates. Cluster auto scaling then automatically replaces any failed nodes, restoring capacity without manual intervention. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of the interplay between infrastructure diversity, application-level resilience, and automated recovery—a common trap is focusing only on node distribution while forgetting the pod-level protection that budgets provide. Remember the memory tip: “Zones for diversity, budgets for stability, scaling for recovery.”
DOP-C02 Resilient Cloud Solutions Practice Question
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 company runs a containerized application on Amazon EKS. The application must be highly available across multiple Availability Zones and must automatically recover from node failures. Which THREE steps should be taken?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Pod Disruption Budgets to ensure a minimum number of pods are available during voluntary disruptions.
Deploy worker nodes across multiple AZs ensures node diversity. Use Pod Disruption Budgets to maintain minimum pod availability. Configure cluster auto scaling to replace failed nodes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Deploy worker nodes across multiple Availability Zones.
Why this is correct
Ensures node diversity.
Related concept
Read the scenario before looking for a memorised answer.
✗
Deploy worker nodes in a single Availability Zone to reduce cross-AZ data transfer costs.
Why it's wrong here
Single AZ is not highly available.
✗
Use a single large instance type for all worker nodes to simplify management.
Why it's wrong here
Single instance type is not a resilience strategy.
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.
