Full question →mediummultiple choiceObjective-mapped
A social media company hosts a web application on AWS that serves millions of users worldwide. The application delivers static content such as images, videos, and CSS files. To improve load times for users in different geographic regions, the company wants to cache this content at AWS locations that are as close to end users as possible. Which component of the AWS global infrastructure should the company use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Availability Zones
An Availability Zone is a physically separate data center within an AWS Region. It is designed for high availability and fault tolerance of compute and storage resources, not for caching content close to end users. Using multiple Availability Zones provides application resilience but does not directly reduce latency for global users.
B
Best answer
Edge Locations
Edge Locations are a global network of data centers used by Amazon CloudFront to cache copies of content closer to users. By serving content from the nearest edge location, the company reduces latency and improves load times for static assets. This is the correct solution for the described requirement.
C
Distractor review
Regional Edge Caches
Regional Edge Caches are intermediate caching layers between CloudFront edge locations and the origin. They are larger and help reduce load on the origin for less-popular content. However, they are not as geographically distributed as edge locations and therefore not the closest to end users. For optimal latency, the company should use edge locations directly.
D
Distractor review
AWS Direct Connect Locations
AWS Direct Connect Locations are physical points of presence where customers can establish dedicated network connections from their on-premises data centers to AWS. This service is used for private, high-bandwidth connectivity, not for caching content or improving user-facing latency. It does not serve cached content to end users.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Edge Locations — This question tests understanding of the AWS global infrastructure components, specifically their roles in content delivery. The correct answer is Edge Locations. Amazon CloudFront uses a global network of edge locations to cache content at locations that are physically close to users, minimizing latency and improving performance. Availability Zones (A) are isolated locations within an AWS Region used for high availability and fault tolerance, not for content caching. Regional Edge Caches (C) are larger caches that sit between CloudFront edge locations and the origin server; they help with less-frequently accessed content but are not as close to users as edge locations. AWS Direct Connect Locations (D) are physical points of presence used to establish dedicated network connections from on-premises to AWS, not for caching content. Therefore, Edge Locations are the correct infrastructure component for this use case.
