- A
Use Amazon CloudFront with multiple origins pointing to ALBs in each region and configure origin failover.
Why wrong: CloudFront origin failover is for origin redundancy, not active-active multi-region routing.
- B
Use Amazon Route 53 latency-based routing with health checks to route traffic to ALBs in each region.
Why wrong: Route 53 latency routing does not use anycast and may not provide optimal performance for all users.
- C
Deploy a single ALB with multiple target groups across regions using cross-zone load balancing.
Why wrong: ALB cannot have target groups in other regions.
- D
Deploy Global Accelerator with endpoints in each region (ALBs) and configure health checks to route traffic to healthy endpoints.
Global Accelerator uses anycast IPs and health checks for optimal routing to healthy endpoints.
ANS-C01 Network Design Practice Question
This ANS-C01 practice question tests your understanding of network design. 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 multi-region active-active architecture for a web application using Application Load Balancers (ALBs) and AWS Global Accelerator. The application must provide low-latency access to users worldwide and automatically route traffic to healthy endpoints. Which design should be used?
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
Deploy Global Accelerator with endpoints in each region (ALBs) and configure health checks to route traffic to healthy endpoints.
Option B is correct because Global Accelerator uses anycast IPs and health checks to route traffic to the closest healthy endpoint. Option A is wrong because Route 53 latency routing with health checks can work but does not use anycast and may not provide the same performance. Option C is wrong because multiple ALBs in a single region would not provide multi-region failover. Option D is wrong because CloudFront with ALB origins can provide low latency but does not support active-active multi-region traffic routing by default.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
