CLF-C02 Cloud Technology and Services Practice Question
A gaming company needs ultra-low latency access to AWS compute for their mobile game players at 5G network edges. Which AWS infrastructure extension enables this?
⚠ Common exam trap
Test-takers frequently confuse AWS Local Zones with Wavelength Zones, but Local Zones are designed for latency-sensitive workloads in metro areas (e.g., media rendering) and lack the direct integration with 5G carrier networks that Wavelength Zones provide.

Correct answer & explanation
✓
AWS Wavelength Zones
AWS Wavelength Zones embed AWS compute and storage services at the edge of 5G networks, enabling ultra-low latency for mobile game players by minimizing the distance data must travel between the device and the application. This is specifically designed for applications that require single-digit millisecond latencies over 5G, such as real-time gaming, AR/VR, and live video processing.
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 Local Zones
Why it's wrong here
AWS Local Zones are extensions of an AWS Region that place selected services such as EC2, EBS, and RDS in metropolitan areas to provide low-latency access to workloads for local users. They are connected to the parent Region and deliver latencies in the single-digit millisecond range for nearby users, but they sit in AWS-owned or partner-operated facilities, not inside mobile carrier 5G networks. While Local Zones are appropriate for general low-latency compute, Wavelength specifically embeds compute within the 5G carrier's edge to serve mobile devices over the cellular network, making Local Zones the wrong answer here.
- ✗
AWS Outposts
Why it's wrong here
AWS Outposts brings native AWS infrastructure, services, and APIs to customer-managed on-premises data centers for a truly consistent hybrid experience. However, it is not placed inside a telecommunications carrier's 5G network, nor is it positioned at the 5G edge that serves mobile devices. Because Outposts is controlled by the customer's local IT environment, it does not provide the embedded, carrier-integrated compute path needed to achieve single-digit millisecond latency for mobile users over 5G, which is specific to Wavelength Zones.
- ✓
AWS Wavelength Zones
Why this is correct
AWS Wavelength Zones are AWS infrastructure deployments embedded directly within the telecommunications service provider's 5G network, close to the radio access network and mobile core. This allows developers to launch EC2 instances and attach EBS volumes in these zones, bringing compute and storage to the network edge so mobile applications can achieve single-digit millisecond latency. Because the zone is logically part of a VPC, applications can split their processing between the Wavelength Zone and the parent AWS Region over the AWS backbone, making Wavelength the correct choice for latency-critical mobile workloads on 5G.
- ✗
Amazon CloudFront Edge Locations
Why it's wrong here
Amazon CloudFront Edge Locations are part of a global content delivery network that caches static and dynamic objects at hundreds of POPs to accelerate web delivery and reduce origin load. They do not run general-purpose compute instances or support full application logic within a customer-managed VPC, and they are not integrated into the 5G carrier network infrastructure. CloudFront can execute lightweight CloudFront Functions for simple request-rewriting, but that is not equivalent to running an EC2 application server at the 5G far edge, so it fails the requirement of providing compute capabilities for mobile edge processing.
