ANS-C01 Network Implementation Practice Question
A company is deploying a global application behind an Application Load Balancer (ALB) in AWS. They want to use AWS Global Accelerator to improve performance by directing traffic to the nearest healthy endpoint. Which configuration is required to achieve this?
⚠ Common exam trap
The ANS-C01 exam often tests the misconception that Route 53 latency-based routing or CloudFront can replace Global Accelerator for performance optimization, but the key differentiator is that Global Accelerator uses anycast IPs and the AWS global network for non-cached, dynamic traffic.
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
✓
Create an accelerator with an endpoint group that includes the ALB as an endpoint
AWS Global Accelerator uses endpoint groups to direct traffic to the nearest healthy endpoint. By creating an accelerator with an endpoint group that includes the ALB as an endpoint, Global Accelerator can route user traffic over the AWS global network to the optimal ALB based on latency and health, improving performance for global users.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create an accelerator with an endpoint group that includes the ALB as an endpoint
Why this is correct
Global Accelerator directs traffic to the nearest healthy endpoint in the endpoint group.
- ✗
Configure Route 53 health checks for the ALB and associate them with Global Accelerator
Why it's wrong here
Global Accelerator performs its own health checks on endpoints.
- ✗
Configure a CloudFront distribution with the ALB as an origin and enable Global Accelerator
Why it's wrong here
CloudFront is a CDN, not used with Global Accelerator in this way.
- ✗
Create a Route 53 latency-based routing record set pointing to the ALB
Why it's wrong here
Global Accelerator does not use Route 53 for routing; it uses anycast IPs.
