Full question →mediummultiple choiceObjective-mapped
A company runs a web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The company wants to serve traffic over HTTPS to encrypt data in transit between clients and the ALB. The security team requires that the SSL/TLS certificate be automatically renewed before expiration and that AWS manage the entire certificate lifecycle. The company does not want to manually upload or manage private keys. 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
AWS Certificate Manager (ACM)
ACM is the correct choice. It automates the provisioning, deployment, and renewal of SSL/TLS certificates for use with AWS services such as ALB, CloudFront, and API Gateway. ACM handles the full certificate lifecycle and keeps private keys secure.
B
Distractor review
AWS Secrets Manager
Secrets Manager is designed to securely store and rotate secrets such as database credentials, API keys, and other sensitive information. It does not manage SSL/TLS certificates for use with load balancers and does not integrate directly with ALB for HTTPS termination.
C
Distractor review
AWS Identity and Access Management (IAM)
IAM allows you to upload server certificates for use with ALB and other services, but it does not provide automatic renewal. You must manually upload a new certificate before expiration, which does not meet the requirement for automated lifecycle management.
D
Distractor review
AWS Key Management Service (KMS)
KMS is a managed service for creating and controlling encryption keys used to encrypt data at rest. It does not issue or manage SSL/TLS certificates, nor does it integrate with ALB for HTTPS termination.
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 Certificate Manager (ACM) — AWS Certificate Manager (ACM) is the correct service because it provisions, manages, and automatically renews public and private SSL/TLS certificates for use with integrated AWS services such as Application Load Balancers, Amazon CloudFront, and Amazon API Gateway. ACM handles the full certificate lifecycle, including renewal, and stores the private key securely without exposing it to customers. The other services listed serve different purposes: Secrets Manager is for rotating secrets like database credentials; IAM can store server certificates but requires manual upload and renewal; KMS manages encryption keys, not SSL/TLS certificates.
