- A
Deploy web and application servers on EC2 instances in an Auto Scaling group across two AZs with an Application Load Balancer. Use Multi-AZ Amazon RDS for MySQL.
ALB and Auto Scaling provide automatic scaling and failover; Multi-AZ RDS provides database failover.
- B
Deploy web and application servers on EC2 instances in an Auto Scaling group in one AZ. Use Amazon Route 53 latency-based routing to another region.
Why wrong: Single AZ is a single point of failure; cross-region adds complexity and latency.
- C
Deploy web, application, and database on a single large EC2 instance in one AZ. Take snapshots every hour.
Why wrong: Single AZ does not provide high availability; snapshot recovery takes time.
- D
Deploy web and application servers on EC2 instances in two AZs with Elastic IP addresses. Use Amazon Route 53 with health checks to route traffic.
Why wrong: Elastic IPs are not highly available; manual intervention needed for failover.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 web application to AWS. The application uses a three-tier architecture with a web server, application server, and MySQL database. The company wants to ensure high availability by deploying across multiple Availability Zones. The web and application servers are stateless. Which solution provides the HIGHEST availability with the LEAST administrative effort?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"least"Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Deploy web and application servers on EC2 instances in an Auto Scaling group across two AZs with an Application Load Balancer. Use Multi-AZ Amazon RDS for MySQL.
Option A is correct: Deploying web and application servers on EC2 instances in an Auto Scaling group across two AZs with an Application Load Balancer ensures high availability and automatic scaling. Multi-AZ Amazon RDS for MySQL provides automatic failover for the database, minimizing administrative effort. Option B (deploying in one AZ) does not provide high availability across AZs. Option C (single large instance) is a single point of failure. Option D (using Elastic IPs and Route 53 health checks) requires manual intervention and is less automated than the ALB solution.
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 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.
