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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
AWS Direct Connect
Why wrong: For dedicated on-premises connectivity, not multi-region optimization.
AWS Global Accelerator
Uses anycast IPs and AWS global network for low latency.
Amazon CloudFront
Why wrong: Designed for content delivery, not real-time application traffic optimization.
Amazon Route 53 Latency Routing
Why wrong: DNS-based routing adds latency due to DNS resolution and TTL.
Answer choices
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.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Direct Connect
Why it's wrong here
For dedicated on-premises connectivity, not multi-region optimization.
AWS Global Accelerator
Why this is correct
Uses anycast IPs and AWS global network for low latency.

Amazon Route 53 Latency Routing
Why it's wrong here
DNS-based routing adds latency due to DNS resolution and TTL.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
