The correct choice is to use EKS with managed node groups across three Availability Zones, combining On-Demand and Spot Instances. This configuration directly supports high availability by distributing worker nodes across multiple AZs, while managed node groups automate EC2 lifecycle tasks like patching and scaling, reducing operational overhead. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your ability to balance cost, availability, and management simplicity—a common trap is choosing Fargate for its serverless appeal, but for long-running workloads, managed node groups with a mix of instance types and Spot Instances offer better cost efficiency and control. The key insight is that EKS managed node groups handle the control plane’s integration with IAM, VPC, and CloudWatch natively, freeing you from manual node management. Memory tip: think “Three AZs, two instance types, zero overhead” to recall the core requirements for multi-AZ high availability with EKS.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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 is migrating a containerized application from on-premises to AWS. The application runs on Kubernetes. The company wants to use Amazon EKS for orchestration. The migration must support high availability across multiple Availability Zones and integrate with AWS services like IAM, VPC, and CloudWatch. The company needs to minimize the operational overhead of managing the Kubernetes control plane. Which EKS configuration should the company use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use EKS with managed node groups using a mix of On-Demand and Spot Instances across three Availability Zones.
Option B is correct because EKS-managed node groups automatically manage the lifecycle of EC2 instances, and using multiple instance types and AZs ensures high availability and cost optimization. Option A is wrong because Fargate is good for serverless but may not be cost-effective for long-running applications. Option C is wrong because self-managed nodes increase operational overhead. Option D is wrong because using only one instance type and one AZ violates high availability requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use EKS with managed node groups using a mix of On-Demand and Spot Instances across three Availability Zones.
Why this is correct
Managed node groups reduce overhead; multi-AZ and mixed instances provide HA and cost savings.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept

✗
Use EKS with self-managed node groups using On-Demand instances in two Availability Zones.
Why it's wrong here
Self-managed nodes increase overhead.
✗
Use EKS with a single managed node group using a single instance type in one Availability Zone.
Why it's wrong here
Single AZ does not provide high availability.
✗
Use EKS with Fargate launch type for all pods.
Why it's wrong here
Fargate may be more expensive for long-running workloads and has limitations.

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.
