Full question →mediummultiple choiceObjective-mapped
A company hosts an e-commerce website on Amazon EC2 instances behind an Application Load Balancer in the us-east-1 Region. The website includes both static assets (product images, CSS files) and dynamic content (user-specific cart data). The company has customers all over the world who complain about slow page load times. The company wants to reduce latency by caching static content closer to users while still allowing dynamic requests to reach the origin. Which AWS service should the company use to meet these requirements?
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
Best answer
Amazon CloudFront with Application Load Balancer as the origin
Correct. Amazon CloudFront is a global content delivery network (CDN) that can cache static content at edge locations closer to users. It also supports dynamic content by forwarding requests to the origin, which can be an Application Load Balancer. This meets both the caching and origin integration requirements.
B
Distractor review
Amazon Route 53 with latency-based routing
Incorrect. Amazon Route 53 with latency-based routing directs user traffic to the region that provides the lowest latency, but it does not cache content at edge locations. Static content would still be served from the origin server, not reducing load times for frequently accessed assets.
C
Distractor review
AWS Global Accelerator with static IP addresses
Incorrect. AWS Global Accelerator improves performance by directing traffic over the AWS global network to the optimal endpoint, but it does not cache content. It is designed for TCP/UDP traffic and can accelerate both static and dynamic content, but without caching, static assets are not served from edge locations.
D
Distractor review
Amazon S3 Transfer Acceleration
Incorrect. Amazon S3 Transfer Acceleration speeds up uploads to S3 buckets over long distances by using AWS edge locations, but it is used for uploading objects to S3, not for serving cached content to end users. It does not integrate with an Application Load Balancer for dynamic content.
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: Amazon CloudFront with Application Load Balancer as the origin — Amazon CloudFront is a content delivery network (CDN) service that caches content at edge locations globally. It can serve both static and dynamic content: static content is cached at the edge for low-latency delivery, while dynamic requests are forwarded to the origin (in this case, the Application Load Balancer) and can still be optimized. This directly addresses the requirement to improve load times for a global customer base while keeping the existing origin architecture.
