The answer is AWS Certificate Manager (ACM). ACM is the correct choice because it provisions, manages, and deploys public and private SSL/TLS certificates for integrated AWS services—such as Elastic Load Balancing, CloudFront, and API Gateway—at no additional cost, and it automatically handles certificate renewal, eliminating the need for manual intervention. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of cost-effective, fully managed security services; a common trap is confusing ACM with third-party certificate authorities or assuming you must manually upload and renew certificates from external providers. Remember that ACM is the only AWS service that offers free SSL/TLS certificate management with automatic renewal for supported resources, making it the go-to solution for securing traffic without ongoing overhead. A helpful memory tip: “ACM Automates Certificates, Minimizing manual work.”
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to provision and manage SSL/TLS certificates for their AWS resources without paying for certificates or manually handling renewals. Which AWS service provides this?
Why wrong: KMS manages cryptographic encryption keys — it doesn't provision SSL/TLS certificates for web services.
B
AWS Certificate Manager (ACM)
ACM provides free SSL/TLS certificates for AWS services with automatic renewal — no certificate purchase, no manual renewal, no CSR submissions required.
C
AWS CloudHSM
Why wrong: CloudHSM provides dedicated HSMs for key storage — it can store private keys, but doesn't provision or renew SSL/TLS certificates.
D
AWS IAM
Why wrong: IAM manages identity and access — it does support uploading certificates for some services but doesn't provision or renew them like ACM.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Certificate Manager (ACM)
AWS Certificate Manager (ACM) provisions, manages, and deploys public and private SSL/TLS certificates for use with AWS services (e.g., Elastic Load Balancing, CloudFront, API Gateway) at no additional cost. ACM automatically handles certificate renewals, eliminating the need for manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS KMS or CloudHSM as certificate management services because they deal with encryption, but they do not provision or renew SSL/TLS certificates.
Detailed technical explanation
How to think about this question
ACM integrates with AWS Certificate Manager Private Certificate Authority (ACM PCA) to issue private certificates for internal use, and it supports both RSA and ECDSA key algorithms. ACM automatically renews certificates issued by public CAs (e.g., Amazon Trust Services) approximately 60 days before expiration, provided the certificate is associated with an integrated AWS service and DNS validation is configured.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
