Quick Answer
The answer is AWS Global Accelerator, Amazon Route 53 latency routing, and Amazon CloudFront. These three services work together to achieve global traffic routing to the nearest healthy endpoint by combining latency-based DNS resolution, anycast IP for fast failover, and edge caching. Route 53 latency routing directs users to the AWS region with the lowest network latency, while Global Accelerator provides static anycast IP addresses that instantly reroute traffic away from unhealthy endpoints, and CloudFront caches static content at edge locations to further reduce latency. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how to architect a global, resilient application layer—a common trap is selecting an Application Load Balancer (ALB) for global routing, but ALBs are regional and cannot perform cross-region failover. Another trap is choosing AWS WAF, which is a security service, not a routing service. Memory tip: think "LGC" for Latency, Global Accelerator, and CloudFront—the three pillars of global, low-latency routing.
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.)
Amazon CloudFront
Correct: Caches content at edge, reducing latency.
Amazon Route 53 with latency-based routing
Correct: Routes to nearest region based on latency.
AWS Global Accelerator
Correct: Provides static anycast IP and fast failover.
AWS WAF
Why wrong: Wrong: WAF is a web application firewall.
Application Load Balancer in each region
Why wrong: Wrong: ALB is regional, not global.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon CloudFront
Options A, C, and E are correct because Route 53 latency routing directs users to the region with lowest latency; Global Accelerator provides anycast IP and fast failover; and CloudFront caches content at edge locations for low latency. Option B is wrong because ALB is regional and not for global routing. Option D is wrong because WAF is for security, not routing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is designing a network for a high-traffic web application that must be highly available across multiple AWS Regions. The application uses Application Load Balancers (ALBs) in each region. Which TWO actions should be taken to route traffic to the nearest healthy endpoint?
mediumWhy B: Route 53 latency-based routing directs traffic to the region with the lowest latency. Health checks ensure traffic is only sent to healthy endpoints. Global Accelerator also provides routing to the nearest healthy endpoint via anycast. Weighted routing does not consider latency. Failover routing is for active-passive. Multi-value answer routing is for DNS-based load balancing without health check integration with latency.
