Full question →mediummultiple choiceObjective-mapped
A company is developing a microservices-based application using Docker containers. The development team wants to run these containers on AWS without having to provision or manage any servers. The solution must automatically scale the containers based on demand and integrate with an Application Load Balancer for traffic distribution. Which AWS service should the team 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
Distractor review
AWS Lambda
AWS Lambda is a serverless compute service for running code in response to events, not for running Docker containers. It does not support container-based microservices in the same way as Fargate.
B
Distractor review
Amazon ECS on Amazon EC2
While Amazon ECS can run Docker containers, using the EC2 launch type requires you to provision and manage the underlying EC2 instances. The requirement is to avoid server management, so this option does not meet that need.
C
Best answer
AWS Fargate
AWS Fargate is a serverless compute engine for containers. It automatically manages the underlying infrastructure, scales containers based on demand, and integrates with Application Load Balancers. This meets all the stated requirements.
D
Distractor review
Amazon Lightsail
Amazon Lightsail provides pre-configured virtual private servers. It does not offer native container orchestration, automatic scaling, or direct integration with Application Load Balancers for container workloads.
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: AWS Fargate — AWS Fargate is a serverless compute engine for containers that runs on Amazon ECS or Amazon EKS. It allows you to run containers without managing the underlying servers, automatically scales based on demand, and integrates with Application Load Balancers. AWS Lambda is for serverless functions, not containers. Amazon ECS on Amazon EC2 requires you to manage the EC2 instances. Amazon Lightsail is a simplified compute service for basic workloads, not designed for container orchestration with auto scaling and ALB integration.
