- A
Change the endpoint in ap-southeast-1 to use the same ALB but with a cross-Region VPC peering
Why wrong: Global Accelerator endpoint must be in the same Region as the endpoint group.
- B
Configure Global Accelerator to use weighted routing to direct more traffic to ap-southeast-1
Why wrong: Traffic already goes to nearest endpoint group, but the ALB is far.
- C
Add an additional ALB in ap-southeast-1 and add it as an endpoint in the ap-southeast-1 endpoint group
Deploying locally reduces latency.
- D
Use Lambda@Edge to cache content at CloudFront edge locations in Asia
Why wrong: CloudFront is different from Global Accelerator.

ANS-C01 Global Accelerator Endpoint Groups Practice Question
This ANS-C01 practice question tests your understanding of network implementation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: global Accelerator Endpoint Groups. 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 uses AWS Global Accelerator to improve performance for a web application hosted on EC2 instances behind an Application Load Balancer (ALB) in a VPC. The Global Accelerator has an endpoint group in the us-east-1 Region with the ALB as an endpoint. Users in Asia report high latency. The company creates a new endpoint group in ap-southeast-1 and adds the same ALB (which is still in us-east-1). However, users in Asia still experience high latency. What should the network engineer do to reduce latency for Asian users?

Correct answer & explanation
✓
Add an additional ALB in ap-southeast-1 and add it as an endpoint in the ap-southeast-1 endpoint group
Global Accelerator routes traffic to the nearest endpoint group based on latency. However, if the endpoint (ALB) is only in us-east-1, traffic from Asia will still be forwarded to us-east-1 after reaching the ap-southeast-1 endpoint group because the endpoint itself is in us-east-1. To reduce latency, the company must deploy the application in ap-southeast-1 and add a local ALB as an endpoint in the ap-southeast-1 endpoint group. Option C correctly describes this. Option A is incorrect because the ALB cannot be in us-east-1 and serve as an endpoint for ap-southeast-1; endpoint group and endpoint must be in the same Region. Option B is incorrect because weighted routing does not change the physical location of the endpoint; the ALB is still distant. Option D uses CloudFront, which is a CDN, not a Global Accelerator solution, and does not reduce latency for the Global Accelerator use case.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap is that the endpoint group with a different endpoint region cannot leverage the regional proximity; you must deploy the application locally.

How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

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.

Global Accelerator Endpoint Groups
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.

Questions learners often ask
What does this ANS-C01 question test?
Network Implementation — This question tests Network Implementation — Global Accelerator Endpoint Groups.
What is the correct answer to this question?
The correct answer is: Add an additional ALB in ap-southeast-1 and add it as an endpoint in the ap-southeast-1 endpoint group — Global Accelerator routes traffic to the nearest endpoint group based on latency. However, if the endpoint (ALB) is only in us-east-1, traffic from Asia will still be forwarded to us-east-1 after reaching the ap-southeast-1 endpoint group because the endpoint itself is in us-east-1. To reduce latency, the company must deploy the application in ap-southeast-1 and add a local ALB as an endpoint in the ap-southeast-1 endpoint group. Option C correctly describes this. Option A is incorrect because the ALB cannot be in us-east-1 and serve as an endpoint for ap-southeast-1; endpoint group and endpoint must be in the same Region. Option B is incorrect because weighted routing does not change the physical location of the endpoint; the ALB is still distant. Option D uses CloudFront, which is a CDN, not a Global Accelerator solution, and does not reduce latency for the Global Accelerator use case.
