CLF-C02 Cloud Technology and Services Practice Question
A media production company has a physical studio in Atlanta, Georgia. The company runs video editing workloads on Amazon EC2 instances that require single-digit millisecond latency to the studio's on-premises storage and workstations. The company wants to use AWS infrastructure that is physically located in or very near Atlanta to achieve this latency, while still having full access to AWS services like EC2, EBS, and VPC. The company does not want to manage the underlying hardware. Which AWS infrastructure option should the company use?
⚠ Common exam trap
Test-takers frequently confuse AWS Local Zones with AWS Outposts, assuming Outposts is the only way to get on-premises-like latency, but Outposts requires customer-managed hardware, whereas Local Zones provide AWS-managed infrastructure in a specific geographic location.
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 Local Zones
AWS Local Zones are an infrastructure deployment that places compute, storage, and database services closer to large population centers, enabling single-digit millisecond latency for latency-sensitive applications. Since the company needs physical proximity to Atlanta without managing hardware, a Local Zone in or near Atlanta provides the required low latency while offering full access to EC2, EBS, and VPC services, with AWS handling the underlying hardware.
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 the customer's on-premises data center, but the customer must provide the facility, power, and cooling. The scenario specifically says the company does not want to manage the underlying hardware, and Outposts still require the customer to manage the physical site. Local Zones are a better fit because they are fully managed by AWS in AWS-owned facilities near the metropolitan area.
When this WOULD be correct
A company needs to run workloads on-premises with low latency to local systems, but requires full access to AWS services like EC2, EBS, and VPC, and is willing to manage the underlying hardware or has a colocation facility.
- ✓
AWS Local Zones
Why this is correct
AWS Local Zones are specifically designed to provide single-digit millisecond latency for applications in a specific geographic area. They are fully managed by AWS and extend the AWS Region to be closer to end users. The company can run EC2 instances in a Local Zone near Atlanta to achieve the required low latency for video editing workloads.
- ✗
AWS Wavelength
Why it's wrong here
AWS Wavelength is designed for applications that require ultra-low latency over 5G mobile networks. It embeds AWS compute and storage at the edge of telecom providers' 5G networks. The scenario does not involve 5G or mobile connectivity; it requires low latency to a physical studio, which is better served by a Local Zone.
When this WOULD be correct
A company needs to run applications on AWS infrastructure embedded within 5G networks to deliver single-digit millisecond latency to mobile devices or IoT endpoints, and does not require direct connection to on-premises resources.
- ✗
AWS Edge Locations
Why it's wrong here
AWS Edge Locations are part of the Amazon CloudFront content delivery network. They cache content to reduce latency for end users but do not run general-purpose compute workloads like EC2 instances. They cannot host the video editing application directly.
When this WOULD be correct
A company wants to reduce latency for static content delivery (e.g., images, videos) to global users. They need a caching layer close to end users but do not require compute or storage services like EC2 or EBS. In that case, using CloudFront with Edge Locations would be the correct answer.
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 Local ZonesCorrect answer▾
Why this is correct
AWS Local Zones are specifically designed to provide single-digit millisecond latency for applications in a specific geographic area. They are fully managed by AWS and extend the AWS Region to be closer to end users. The company can run EC2 instances in a Local Zone near Atlanta to achieve the required low latency for video editing workloads.
✗AWS OutpostsWrong answer — click to see why▾
Why this is wrong here
AWS Outposts requires the company to manage and maintain the underlying hardware on-premises, which contradicts the requirement of not wanting to manage hardware. Additionally, Outposts are typically deployed in customer data centers, not in a specific AWS-managed location near Atlanta.
★ When this WOULD be the correct answer
A company needs to run workloads on-premises with low latency to local systems, but requires full access to AWS services like EC2, EBS, and VPC, and is willing to manage the underlying hardware or has a colocation facility.
Why candidates choose this
Candidates may think Outposts provide the closest physical proximity to the studio because they are deployed on-premises, but they overlook the management requirement and the fact that Outposts are customer-managed hardware.
✗AWS WavelengthWrong answer — click to see why▾
Why this is wrong here
AWS Wavelength is designed for ultra-low latency applications at the edge of 5G networks, not for low-latency connectivity to on-premises storage and workstations in a specific metro area.
★ When this WOULD be the correct answer
A company needs to run applications on AWS infrastructure embedded within 5G networks to deliver single-digit millisecond latency to mobile devices or IoT endpoints, and does not require direct connection to on-premises resources.
Why candidates choose this
Candidates may confuse 'edge' concepts and assume Wavelength provides general low-latency compute near any location, overlooking its dependency on telecom 5G networks.
✗AWS Edge LocationsWrong answer — click to see why▾
Why this is wrong here
AWS Edge Locations are content delivery endpoints for CloudFront and Route 53, not compute infrastructure. They do not provide EC2 instances, EBS volumes, or VPCs, so they cannot meet the company's need for low-latency video editing workloads with full AWS service access.
★ When this WOULD be the correct answer
A company wants to reduce latency for static content delivery (e.g., images, videos) to global users. They need a caching layer close to end users but do not require compute or storage services like EC2 or EBS. In that case, using CloudFront with Edge Locations would be the correct answer.
Why candidates choose this
Candidates may confuse 'edge' with 'close proximity' and assume Edge Locations provide compute resources. They might also think that any AWS infrastructure near a location can run EC2, overlooking that Edge Locations are only for content caching and DNS.
