- A
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
AWS Secrets Manager
Why wrong: 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
AWS Identity and Access Management (IAM)
Why wrong: 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
AWS Key Management Service (KMS)
Why wrong: 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.
CLF-C02 Security and Compliance Practice Question
This CLF-C02 practice question tests your understanding of security and compliance. 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. A key principle to apply: aCM automates SSL/TLS certificate provisioning and renewal.. 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 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
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) is the correct choice because it integrates directly with Application Load Balancers to provision, deploy, and automatically renew SSL/TLS certificates. ACM manages the entire certificate lifecycle, including private key generation and storage, without requiring manual intervention. This meets the security team's requirement for automatic renewal and AWS-managed certificate lifecycle.
Key principle: ACM automates SSL/TLS certificate provisioning and renewal.

Related concept
ACM automates SSL/TLS certificate provisioning and renewal.
- ✗
AWS Secrets Manager
Why it's wrong here
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.
When this WOULD be correct
A company needs to store and automatically rotate a database password or API key used by an application running on EC2. The requirement is to securely manage secrets with automatic rotation, not to handle SSL/TLS certificates.
- ✗
AWS Identity and Access Management (IAM)
Why it's wrong here
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.
When this WOULD be correct
A company needs to securely store and rotate database credentials or API keys for an application running on EC2, and wants to automate credential rotation without managing secrets manually. In that scenario, AWS Secrets Manager would be the correct answer.
- ✗
AWS Key Management Service (KMS)
Why it's wrong here
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.
When this WOULD be correct
A company needs to encrypt data stored in an S3 bucket using a customer-managed key and wants to control key rotation and access policies. AWS KMS would be the correct service to create and manage the CMK.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓AWS Certificate Manager (ACM)Correct answer▾
Why this is correct
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.
✗AWS Secrets ManagerWrong answer — click to see why▾
Why this is wrong here
AWS Secrets Manager is designed to securely store and rotate secrets like database credentials and API keys, not to manage SSL/TLS certificates for HTTPS termination. It does not integrate with ALB to automatically deploy and renew certificates.
★ When this WOULD be the correct answer
A company needs to store and automatically rotate a database password or API key used by an application running on EC2. The requirement is to securely manage secrets with automatic rotation, not to handle SSL/TLS certificates.
Why candidates choose this
Candidates may confuse Secrets Manager's automatic rotation feature with certificate renewal, assuming it can manage SSL/TLS certificates similarly, but ACM is the dedicated service for certificate lifecycle management.
✗AWS Identity and Access Management (IAM)Wrong answer — click to see why▾
Why this is wrong here
IAM is used for managing users, groups, roles, and permissions, not for SSL/TLS certificate lifecycle management or automatic renewal. ACM is the service designed for provisioning, managing, and deploying SSL/TLS certificates.
★ When this WOULD be the correct answer
A company needs to securely store and rotate database credentials or API keys for an application running on EC2, and wants to automate credential rotation without managing secrets manually. In that scenario, AWS Secrets Manager would be the correct answer.
Why candidates choose this
Candidates may confuse IAM's role in managing permissions for certificate operations (like uploading certificates via IAM) with the actual certificate lifecycle management service, or think IAM can handle certificates because it supports server certificates for some AWS services.
✗AWS Key Management Service (KMS)Wrong answer — click to see why▾
Why this is wrong here
AWS KMS is used to create and manage encryption keys for data at rest, not for SSL/TLS certificate lifecycle management. It does not provide certificate issuance, renewal, or deployment to ALBs.
★ When this WOULD be the correct answer
A company needs to encrypt data stored in an S3 bucket using a customer-managed key and wants to control key rotation and access policies. AWS KMS would be the correct service to create and manage the CMK.
Why candidates choose this
Candidates may confuse KMS with ACM because both involve encryption and 'key management,' but KMS handles symmetric encryption keys for data at rest, not public-key certificates for TLS.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS Secrets Manager or KMS with certificate management, but neither service handles SSL/TLS certificate issuance or automatic renewal for load balancers; ACM is the only service that provides fully managed certificate lifecycle for ALB HTTPS termination.
Detailed technical explanation
How to think about this question
ACM uses AWS-managed Certificate Authority (CA) to issue X.509 v3 certificates with a default validity of 13 months (395 days). When associated with an ALB, ACM automatically renews the certificate before expiration by generating a new key pair and re-issuing the certificate, then seamlessly updates the ALB listener without downtime. This automated renewal relies on DNS validation or email validation to prove domain ownership, and the private key never leaves AWS's secure infrastructure.
KKey Concepts to Remember
- ACM automates SSL/TLS certificate provisioning and renewal.
- ACM integrates directly with AWS services like ALB, CloudFront, and API Gateway.
- ACM manages the entire certificate lifecycle, including private key security.
- ACM certificates are free for use with integrated AWS services.
TExam Day Tips
- 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.
Key takeaway
ACM automates SSL/TLS certificate provisioning and renewal.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
