ANS-C01 Network Design Practice Question
A company is designing a multi-region architecture using AWS Global Accelerator and Application Load Balancers (ALBs) in two AWS Regions. They want to route traffic to the closest healthy endpoint and minimize latency. Which configuration best meets these requirements?
⚠ Common exam trap
AWS often tests the misconception that Route 53 latency-based routing is equivalent to Global Accelerator for multi-region traffic optimization, but candidates must remember that DNS-based routing introduces caching delays and lacks the anycast edge routing and fast health check failover that Global Accelerator provides.
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 a Global Accelerator with endpoint groups in each region, each pointing to the regional ALB.
AWS Global Accelerator uses the Anycast IP address to route traffic to the nearest edge location, then forwards it over the AWS global network to the closest healthy endpoint group. By configuring endpoint groups in each region, each pointing to the regional ALB, Global Accelerator provides both low-latency routing and automatic failover, meeting the requirement for multi-region traffic distribution to the closest healthy endpoint.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy a single ALB in one region and use Route 53 geolocation routing to direct traffic.
Why it's wrong here
Geolocation routing does not consider latency or endpoint health dynamically, and a single ALB is a single point of failure.
- ✗
Use Amazon Route 53 latency-based routing with ALBs in each region.
Why it's wrong here
Route 53 latency-based routing does not provide anycast IPs and can be slow to propagate changes.
- ✓
Create a Global Accelerator with endpoint groups in each region, each pointing to the regional ALB.
Why this is correct
Global Accelerator uses anycast IPs to route traffic to the nearest healthy endpoint, with built-in health checks and fast failover.
- ✗
Use an Application Load Balancer in one region and a Network Load Balancer in another with cross-zone load balancing.
Why it's wrong here
This does not provide global routing or proximity-based traffic distribution.

Same concept, more angles
1 more way this is tested on ANS-C01
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. Which THREE of the following are benefits of using AWS Global Accelerator over Amazon CloudFront for a global application that uses TCP traffic? (Select THREE.)
hard- A.Provides content caching at edge locations.
- ✓ B.Provides static IP addresses that act as a fixed entry point.
- ✓ C.Supports TCP and UDP traffic.
- ✓ D.Can be used with Application Load Balancers as endpoints.
- E.Automatically integrates with AWS WAF and AWS Shield Advanced.
Why B: AWS Global Accelerator provides static IP addresses that act as a fixed entry point for your application, which is a key benefit over Amazon CloudFront. CloudFront uses dynamic, regional edge IP addresses that can change, whereas Global Accelerator offers two static anycast IP addresses that remain constant, simplifying DNS management and firewall whitelisting for TCP-based global applications.
