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 network for a global application that requires low latency between users and application servers. They plan to use multiple AWS regions and want to route users to the nearest healthy endpoint. Which THREE services should they use together? (Select THREE.)
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
✓
Amazon CloudFront
Amazon CloudFront is correct because it provides a global content delivery network (CDN) that caches static and dynamic content at edge locations, reducing latency by serving users from the nearest edge. It integrates with AWS origins (like ALBs) and can route requests to the closest healthy origin, supporting low-latency delivery for global applications.
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
The ANS-C01 exam often tests the misconception that a single service (like CloudFront or Route 53 alone) can solve global latency, but the correct answer requires combining three complementary services—CloudFront for caching, Route 53 for DNS-based routing, and Global Accelerator for network path optimization—to fully address the requirement of routing users to the nearest healthy endpoint.
Detailed technical explanation
How to think about this question
Under the hood, CloudFront uses a global network of edge locations that terminate TCP connections close to users, reducing round-trip time (RTT). It supports origin failover and can be paired with Route 53 latency-based routing to direct traffic to the optimal regional ALB, while AWS Global Accelerator uses Anycast IPs to route traffic over the AWS backbone, avoiding public internet congestion. In real-world scenarios, combining these three services allows a global application to achieve sub-100ms latency by leveraging edge caching, intelligent DNS resolution, and optimized network paths.
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.
TExam Day Tips
- 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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
