- A
AWS Global Accelerator
Global Accelerator improves performance by routing traffic over the AWS backbone to the nearest edge.
- B

Question 1,015 of 1,705
AWS Global Accelerator for Latency-Sensitive Global Applications
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 deploying a latency-sensitive application across multiple AWS Regions. They want to use the AWS global network to route traffic to the nearest edge location for fast content delivery. Which service should they use?
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
✓
AWS Global Accelerator
AWS Global Accelerator uses the AWS global network to direct traffic to the nearest edge location via Anycast IP addresses, then routes it over the AWS backbone to the optimal regional endpoint. This minimizes latency and jitter for latency-sensitive applications by avoiding the public internet and providing static IP addresses for traffic management.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon Route 53
Why it's wrong here
Route 53 provides DNS resolution and latency-based routing but does not use edge locations for traffic optimization.
- ✗

Why it's wrong here
CloudFront is optimized for caching, not dynamic application acceleration.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The ANS-C01 exam often tests the distinction between a CDN (CloudFront) and a global network accelerator (Global Accelerator), where candidates mistakenly choose CloudFront for latency-sensitive non-HTTP traffic or real-time applications that require static IP addresses and TCP/UDP optimization.
Detailed technical explanation
How to think about this question
Global Accelerator leverages Anycast IP addresses so that traffic enters the AWS network at the closest edge location, then traverses the AWS global backbone to the chosen regional endpoint (e.g., an ALB, NLB, or EC2 instance). It supports both TCP and UDP, provides health checks and failover, and can handle sudden traffic spikes by distributing load across multiple regions, making it ideal for gaming, IoT, or real-time streaming applications.
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
- 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.

Same concept, more angles
1 more ways 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. A company is deploying a latency-sensitive application across two AWS Regions using Application Load Balancers (ALBs) and AWS Global Accelerator. The application uses TCP port 8443. Which configuration ensures the lowest possible latency for global users?
hard- A.Use Amazon CloudFront with the ALBs as origins.
- B.Use Amazon Route 53 latency-based routing with ALB endpoints in each Region.
- ✓ C.Use AWS Global Accelerator with endpoints as the ALBs in each Region.
- D.Deploy a Network Load Balancer in each Region and use Route 53 geoproximity routing.
Why C: AWS Global Accelerator uses the Anycast static IP addresses to route traffic over the AWS global network to the optimal ALB endpoint, minimizing internet hops and latency. For TCP port 8443, Global Accelerator preserves the client IP and provides connection termination at the edge, ensuring the lowest possible latency for global users by avoiding the public internet.
