Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company runs a containerized application that uses multiple Docker containers. The development team wants to run these containers on AWS without provisioning or managing any EC2 instances. They also do not want to manage the container orchestration control plane. The application requires consistent access to persistent storage volumes that can be attached to containers. Which AWS service should the team use to run the containers with the least operational overhead?
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
Amazon EC2 with a container-optimized AMI
This option still requires the team to provision, manage, and patch EC2 instances, and manage the container orchestration control plane (e.g., installing Docker, managing cluster state). This does not meet the requirement of zero server management.
B
Distractor review
AWS Lambda
AWS Lambda is a serverless compute service for running code (functions), not for running Docker containers as-is. While Lambda can package and run container images, it is not designed for running multi-container applications with persistent storage volumes in the same way as container orchestration services. Lambda also has execution time and resource limits that are not suitable for all containerized workloads.
C
Best answer
AWS Fargate
AWS Fargate is a serverless compute engine for containers. It eliminates the need to provision and manage EC2 instances or the container orchestration control plane. You define your containerized application (task definition) and Fargate launches and runs the containers. Fargate also supports persistent storage through Amazon EFS or Docker volumes, meeting the storage requirement with minimal operational overhead.
D
Distractor review
Amazon ECR (Amazon Elastic Container Registry)
Amazon ECR is a fully managed container image registry for storing, managing, and deploying container images. It does not run containers. ECR is used to store images that can be pulled by a compute service like Fargate or EC2, but by itself it cannot run the application.
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 works with both Amazon ECS and Amazon EKS. With Fargate, you do not need to provision or manage EC2 instances or the container orchestration control plane. You define your containers and the required resources (CPU, memory, storage), and AWS runs them. This matches the requirement of minimal operational overhead without managing servers or a control plane.
