Full question →mediummultiple choiceObjective-mapped
A development team needs to deploy a web application on AWS. They want to avoid managing the underlying infrastructure, such as EC2 instances and load balancers, but still need the ability to control scaling, update the application code, and perform rollbacks. The application must scale automatically based on demand and remain highly available. Which AWS service should the team 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
Best answer
AWS Elastic Beanstalk
Correct. AWS Elastic Beanstalk is a PaaS that abstracts the underlying infrastructure (EC2, load balancers, scaling) and automatically manages deployment, scaling, and health monitoring. Developers can upload code and configure scaling and rollback policies without managing servers.
B
Distractor review
Amazon EC2 with Auto Scaling groups and an Application Load Balancer
Incorrect. While this combination provides scaling and load balancing, it requires the team to manually configure and manage EC2 instances, security groups, and the load balancer. This does not meet the requirement to avoid managing the underlying infrastructure.
C
Distractor review
AWS Lambda
Incorrect. AWS Lambda runs code in response to events and is designed for stateless, short-lived functions. It is not intended for hosting a complete web application with persistent connections or long-running processes, making it unsuitable for this scenario.
D
Distractor review
Amazon ECS using the EC2 launch type
Incorrect. Amazon ECS with the EC2 launch type gives the team control over container placement and cluster management, but they must still manage the EC2 instances in the cluster, including patching and scaling the underlying instances. This does not eliminate infrastructure management.
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 Elastic Beanstalk — AWS Elastic Beanstalk is a Platform as a Service (PaaS) offering that automatically handles capacity provisioning, load balancing, auto scaling, and application health monitoring. Developers simply upload their code and Elastic Beanstalk manages the deployment, including environment creation and updates. It provides built-in support for rollbacks and scaling policies. This contrasts with managing individual EC2 instances manually, which requires significant operational overhead. AWS Lambda is designed for event-driven, short-running functions and is not suitable for hosting an entire web application. Amazon ECS with the EC2 launch type gives fine-grained control but requires the team to manage the underlying EC2 instances and cluster, which contradicts the requirement to avoid infrastructure management.
