Question 67 of 988
CLF-C02 Cloud Technology and Services Practice Question
A company is developing a real-time multiplayer game that requires extremely low latency (under 10ms) for player interactions. The game will be accessed by mobile users on 5G networks in select metropolitan areas. The company wants to run the game server logic as close to the users as possible, leveraging the low latency of 5G and avoiding the round trip to an AWS Region. Which AWS service should the company use to deploy the game server compute at the edge of the 5G network?
⚠ Common exam trap
Many candidates confuse AWS Local Zones with Wavelength, but Local Zones reduce latency only to ~10-20ms from a nearby metro area, not the sub-10ms edge latency achievable only by embedding compute inside the 5G carrier's network via Wavelength.
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 Wavelength
AWS Wavelength is designed specifically to bring AWS compute and storage services to the edge of 5G networks, embedding AWS infrastructure within telecommunications providers' data centers. This enables sub-10ms latency for mobile users by eliminating the round trip to a regional AWS Region, making it ideal for real-time multiplayer game server logic on 5G.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Outposts
Why it's wrong here
AWS Outposts bring native AWS services to on-premises data centers, but they are designed for hybrid cloud use cases, not for embedding compute within a 5G mobile network. Outposts would not provide the sub-10ms latency required for a 5G edge gaming scenario.
When this WOULD be correct
A company needs to run workloads on-premises with low latency to local systems, requiring full AWS services locally for compliance or data residency. For example, a factory using IoT sensors that must process data on-site with minimal delay.
- ✗
AWS Local Zones
Why it's wrong here
AWS Local Zones place compute resources closer to end users in specific metropolitan areas, reducing latency compared to an AWS Region. However, they are not embedded within the 5G network operator's infrastructure. While they reduce latency, they typically do not achieve the extremely low latencies needed for real-time interactive 5G applications.
When this WOULD be correct
A company needs to run latency-sensitive applications (e.g., video rendering, real-time analytics) for users in a specific metropolitan area, but the application can tolerate single-digit millisecond latency to a nearby AWS Region and does not require integration with telecom 5G networks.
- ✓
AWS Wavelength
Why this is correct
AWS Wavelength is the correct choice. It embeds AWS compute and storage at the edge of 5G networks, directly within the mobile network operator's data centers. This enables developers to build applications that require ultra-low latency (single-digit milliseconds) for mobile devices on 5G, ideal for real-time gaming.
- ✗
AWS Global Accelerator
Why it's wrong here
AWS Global Accelerator improves the availability and performance of applications by directing traffic over the AWS global network to the optimal endpoint. It does not deploy compute resources at the edge; it only optimizes routing. Therefore, it cannot satisfy the requirement of running game server logic at the 5G edge.
When this WOULD be correct
A company wants to improve the performance and availability of a global web application by directing user traffic to the nearest healthy endpoint in an AWS Region, using static IP addresses and the AWS global network. Global Accelerator would be the correct choice to reduce latency and packet loss for internet traffic.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓AWS WavelengthCorrect answer▾
Why this is correct
AWS Wavelength is the correct choice. It embeds AWS compute and storage at the edge of 5G networks, directly within the mobile network operator's data centers. This enables developers to build applications that require ultra-low latency (single-digit milliseconds) for mobile devices on 5G, ideal for real-time gaming.
✗AWS OutpostsWrong answer — click to see why▾
Why this is wrong here
AWS Outposts extends AWS infrastructure to on-premises data centers, not to 5G network edge locations. It does not integrate with 5G networks to provide sub-10ms latency for mobile users in metropolitan areas.
★ When this WOULD be the correct answer
A company needs to run workloads on-premises with low latency to local systems, requiring full AWS services locally for compliance or data residency. For example, a factory using IoT sensors that must process data on-site with minimal delay.
Why candidates choose this
Candidates may think Outposts brings compute 'closer to users' in a general sense, not realizing it is for on-premises deployment, not telecom edge.
✗AWS Local ZonesWrong answer — click to see why▾
Why this is wrong here
AWS Local Zones place compute and storage closer to end users but still require traffic to traverse the AWS backbone to the parent Region, adding latency that exceeds the sub-10ms requirement for 5G edge gaming.
★ When this WOULD be the correct answer
A company needs to run latency-sensitive applications (e.g., video rendering, real-time analytics) for users in a specific metropolitan area, but the application can tolerate single-digit millisecond latency to a nearby AWS Region and does not require integration with telecom 5G networks.
Why candidates choose this
Candidates confuse Local Zones with edge computing, assuming that placing resources in a Local Zone automatically provides the ultra-low latency needed for 5G applications, without understanding that Wavelength embeds compute directly into the 5G carrier network.
✗AWS Global AcceleratorWrong answer — click to see why▾
Why this is wrong here
AWS Global Accelerator improves application availability and performance by directing traffic over the AWS global network, but it does not provide compute at the edge of the 5G network. It cannot achieve the sub-10ms latency required for game server logic because it still routes traffic to a regional origin.
★ When this WOULD be the correct answer
A company wants to improve the performance and availability of a global web application by directing user traffic to the nearest healthy endpoint in an AWS Region, using static IP addresses and the AWS global network. Global Accelerator would be the correct choice to reduce latency and packet loss for internet traffic.
Why candidates choose this
Candidates may think Global Accelerator can reduce latency by routing traffic over AWS's global network, but they overlook that it does not host compute at the edge; it only optimizes the network path to regional resources.
