The correct choice is AWS Global Accelerator because it provides static IP addresses and routes traffic to the closest healthy endpoint via the AWS global network, bypassing DNS caching and TTL delays. Unlike Route 53 latency routing, which is a DNS-based approach that can suffer from client-side caching and slower failover, Global Accelerator uses anycast IPs and the AWS backbone to optimize traffic flow in real time, making it far more efficient for global load balancing with regional ALBs. On the ANS-C01 exam, this distinction tests your understanding of the trade-off between DNS-based routing and network-layer traffic optimization—a common trap is assuming Route 53 latency routing is sufficient for performance-sensitive, multi-region architectures. Remember the memory tip: “DNS is a map, Global Accelerator is a highway”—Route 53 tells clients where to go, but Global Accelerator actively drives traffic to the fastest healthy endpoint.
ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. 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 architecture with an Application Load Balancer (ALB) in each region. They need to route traffic to the closest healthy endpoint. Which AWS service should be used for global load balancing?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Global Accelerator with an endpoint group in each region.
AWS Global Accelerator provides static IP addresses and routes traffic to the closest healthy endpoint, improving performance and availability. Option A is wrong because an ALB is regional. Option B is wrong because a Network Load Balancer is also regional. Option C is wrong because Route 53 with latency routing is a DNS-based approach, not as efficient as Global Accelerator for traffic optimization.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use a single Application Load Balancer in one region with cross-region VPC peering.
Why it's wrong here
ALB is regional and cannot span regions.
✓
Use AWS Global Accelerator with an endpoint group in each region.
Why this is correct
Global Accelerator provides anycast IP and routes to the closest healthy endpoint.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use Route 53 latency-based routing with health checks.
Why it's wrong here
DNS-based routing has caching and propagation delays.
✗
Use a Network Load Balancer in each region and Route 53 weighted routing.
Why it's wrong here
NLB is regional; weighted routing doesn't consider latency.
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.

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.

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.

What is the correct answer to this question?
The correct answer is: Use AWS Global Accelerator with an endpoint group in each region. — AWS Global Accelerator provides static IP addresses and routes traffic to the closest healthy endpoint, improving performance and availability. Option A is wrong because an ALB is regional. Option B is wrong because a Network Load Balancer is also regional.
