The answer is to create a Global Accelerator accelerator with endpoint groups in each region, each pointing to the respective ALB. This configuration works because AWS Global Accelerator uses Anycast IP addresses to route traffic over the AWS global network to the nearest healthy endpoint, automatically directing North American users to us-east-1 and European users to eu-west-1 based on latency and health checks. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this question tests your understanding of how Global Accelerator differs from DNS-based routing—a common trap is confusing it with Route 53 latency-based routing, which relies on DNS caching and lacks the real-time Anycast optimization that Global Accelerator provides. Remember that Global Accelerator operates at the network layer with static Anycast IPs, not at the DNS layer, making it ideal for global accelerator multi-region routing scenarios where low-latency failover is critical. Memory tip: think “Anycast, not DNS-cast” to distinguish Global Accelerator from Route 53.
ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 deploying a global application with users in North America and Europe. They have set up an Application Load Balancer (ALB) in us-east-1 and another in eu-west-1. They want to route users to the nearest ALB using AWS Global Accelerator. What is the correct configuration to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Global Accelerator accelerator with endpoint groups in each region, each pointing to the respective ALB
Option A is correct because Global Accelerator uses Anycast IP addresses and health checks to route traffic to the nearest healthy endpoint (ALB). Option B is wrong because Route 53 latency-based routing does not use Anycast; it relies on DNS, which can be cached. Option C is wrong because CloudFront is a CDN, not a load balancer for dynamic content without caching. Option D is wrong because a Network Load Balancer (NLB) is not needed; Global Accelerator can directly target ALBs.
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 Amazon CloudFront with origins pointing to each ALB
Why it's wrong here
Incorrect; CloudFront is for content delivery, not for dynamic application routing without caching.
✗
Place each ALB behind a Network Load Balancer and use Global Accelerator
Why it's wrong here
Incorrect; Global Accelerator can directly target ALBs without an NLB.
✓
Create a Global Accelerator accelerator with endpoint groups in each region, each pointing to the respective ALB
Why this is correct
Correct; Global Accelerator uses Anycast to route to the nearest healthy ALB.

Read the scenario before looking for a memorised answer.
✗
Create a Route 53 latency record set with aliases to each ALB
Why it's wrong here
Incorrect; Route 53 latency routing is DNS-based and can be cached, leading to suboptimal routing.
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.

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 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.
