- A
Deploy the application in multiple Regions and use Amazon Route 53 latency-based routing with active-passive failover.
Why wrong: This requires multi-Region deployment, increasing operational overhead; Route 53 DNS resolution adds latency.
- B
Create an Amazon CloudFront distribution with Lambda@Edge to proxy requests to the ALB.
Why wrong: Lambda@Edge is for lightweight edge computing, not for proxying API traffic; it adds complexity and potential latency.
- C
Create an AWS Global Accelerator accelerator with the ALB as an endpoint.
Global Accelerator uses the AWS global network and anycast IPs to route traffic to the nearest healthy endpoint, reducing latency without multi-Region deployment.
- D
Create an Amazon CloudFront distribution with the ALB as the origin.
Why wrong: CloudFront adds caching which is not suitable for dynamic APIs; it also adds latency for uncached requests.
Quick Answer
The correct choice is AWS Global Accelerator because it leverages the AWS global network to route traffic to the optimal endpoint, providing low-latency global API performance without caching or code changes. Unlike CloudFront, which is designed for cacheable content, Global Accelerator excels at handling dynamic, non-cacheable API traffic by using Anycast IP addresses to direct users to the nearest edge location, then tunneling traffic over the AWS backbone to the Application Load Balancer. On the SAP-C02 exam, this scenario tests your ability to distinguish between edge services: Global Accelerator is the go-to for latency-sensitive, non-cacheable workloads, while CloudFront is better for static or cacheable content, and Lambda@Edge is for lightweight code execution, not proxying. A common trap is choosing CloudFront for dynamic APIs, but remember that Global Accelerator avoids the overhead of cache invalidation and offers faster failover. Memory tip: think "GA for global acceleration" — it’s the direct, low-latency path for APIs that cannot be cached.
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new 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 designing a global application that requires a highly available and low-latency API. The API will be consumed by clients across the world. The backend consists of an Application Load Balancer (ALB) in front of an Auto Scaling group of EC2 instances in a single AWS Region. The company wants to improve performance for global users. Which solution meets these requirements with minimal operational overhead?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create an AWS Global Accelerator accelerator with the ALB as an endpoint.
Option D is correct because AWS Global Accelerator uses the AWS global network to route traffic to the optimal endpoint, providing low latency and high availability. Option A is wrong because Lambda@Edge is for content transformation, not API proxying. Option B is wrong because CloudFront can cache API responses but is not ideal for dynamic APIs that require low latency; Global Accelerator is better for non-cacheable traffic. Option C is wrong because active-passive setup with Route 53 failover does not optimize latency for global users.
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
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.
