Question 1,063 of 1,705
AWS Global Accelerator for Real-Time Gaming
This ANS-C01 practice question tests your understanding of network design. 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 designing a network for a real-time gaming application that requires extremely low latency between players. The application will be deployed on EC2 instances in multiple AWS regions. Which AWS service provides the best latency performance by using the AWS global network and anycast IPs?
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 and anycast IPs to route traffic to the optimal edge location, then over the AWS backbone to the nearest healthy endpoint. This minimizes internet hops and latency, making it ideal for real-time gaming applications that require consistent low latency across multiple regions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
DNS-based routing adds latency due to DNS resolution and TTL.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse CloudFront's edge caching with Global Accelerator's network path optimization, but CloudFront does not use anycast IPs for dynamic traffic routing and cannot provide the same low-latency performance for real-time applications that require direct connections to backend servers.
Detailed technical explanation
How to think about this question
AWS Global Accelerator leverages the Anycast IP address space (e.g., 15.0.0.0/8) to announce the same IP from multiple edge locations, so traffic naturally flows to the nearest edge via BGP routing. It then uses the AWS global backbone to route traffic to the optimal endpoint, avoiding public internet congestion and providing TCP termination at the edge for improved performance. In real-world gaming scenarios, this reduces jitter and packet loss by up to 60% compared to standard internet routing, and it supports static IP addresses that remain constant even if endpoints change.
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
2 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 designing a network for a real-time gaming application that requires the lowest possible latency across AWS Regions. The application uses UDP traffic. Which AWS service should be used to optimize traffic routing?
hard- A.AWS Direct Connect with multiple connections.
- ✓ B.AWS Global Accelerator.
- C.Amazon Route 53 with latency-based routing.
- D.Amazon CloudFront with custom origins.
Why B: AWS Global Accelerator uses the Anycast IP address concept to route UDP traffic over the AWS global network, minimizing latency by directing traffic to the nearest healthy endpoint. It is specifically designed for real-time applications like gaming that require low latency and jitter, and it supports UDP traffic natively.
Variation 2. A company is designing a network for a real-time gaming application that requires low latency and high throughput between game servers in multiple regions. The application uses UDP traffic. Which AWS service should be used to route traffic between regions?
hard- A.AWS Transit Gateway
- ✓ B.AWS Global Accelerator
- C.Amazon CloudFront
- D.Amazon Route 53
Why B: AWS Global Accelerator uses the Anycast IP address and the AWS global network to route UDP traffic from users to the optimal regional endpoint, minimizing latency and jitter. It is designed for real-time applications like gaming that require low-latency and high-throughput UDP traffic between regions, as it bypasses the public internet and leverages AWS's internal backbone.
