Full question →mediummultiple choiceObjective-mapped
A company hosts an e-commerce website on Amazon EC2 instances in the us-east-1 Region. The website serves static assets (images, CSS, and JavaScript) to a global user base. Users in Europe and Asia report slow page load times. The company needs to improve the performance of delivering these static assets to all users without modifying the application code or provisioning additional origin servers. Which AWS service 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
Deploy the website on additional Amazon EC2 instances in the eu-west-1 and ap-southeast-1 Regions, and use a Network Load Balancer to distribute traffic across all Regions.
This approach requires managing multiple origin servers and does not leverage edge caching. It is more complex and costly, and still may not provide the same performance benefit as a CDN for static assets.
B
Best answer
Use Amazon CloudFront to distribute the static assets from AWS edge locations.
CloudFront caches static content at edge locations around the world. When a user requests a file, CloudFront serves it from the nearest edge location, reducing latency and improving load times without any changes to the origin application.
C
Distractor review
Use Amazon Route 53 with geolocation routing policies to route users to the nearest AWS Region for the website.
Route 53 geolocation routing directs DNS queries to the appropriate origin based on the user's location, but the origin servers remain in a single Region or few Regions. It does not cache content, so users still experience latency from the origin server's location.
D
Distractor review
Enable S3 Transfer Acceleration on the Amazon S3 bucket that stores the static assets.
S3 Transfer Acceleration improves upload speeds to S3 buckets over long distances by using AWS edge locations. It is not designed for accelerating downloads or serving 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: Use Amazon CloudFront to distribute the static assets from AWS edge locations. — Amazon CloudFront is a content delivery network (CDN) service that caches content at edge locations worldwide. By distributing static assets from edge locations close to users, latency is significantly reduced. The other options do not provide global edge caching for static content: a multi-region deployment with NLB adds complexity and cost; Route 53 geolocation routing only optimizes DNS resolution but still routes to the origin; S3 Transfer Acceleration is designed for uploads, not downloads of cached content.
