- A
AWS Key Management Service (AWS KMS)
Why wrong: KMS manages encryption keys, not SSL/TLS certificates. It cannot be used to provision certificates for API Gateway.
- B
AWS Certificate Manager (ACM)
ACM provides a simple way to create, manage, and deploy public and private SSL/TLS certificates for use with AWS services like API Gateway, CloudFront, and Elastic Load Balancers.
- C
AWS Identity and Access Management (IAM)
Why wrong: IAM can be used to upload server certificates for use with some services, but it is a legacy approach. ACM is the preferred and more integrated service for SSL/TLS management.
- D
AWS Secrets Manager
Why wrong: Secrets Manager is for storing and rotating secrets such as database credentials and API keys, not for managing SSL/TLS certificates.
DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws 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 developer is building a REST API using Amazon API Gateway and AWS Lambda. The API needs to support a custom domain name and an SSL/TLS certificate. Which AWS service should the developer use to manage the SSL/TLS certificate?
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 service for provisioning, managing, and deploying SSL/TLS certificates for use with AWS services like API Gateway. ACM integrates directly with API Gateway to automatically renew certificates and attach them to custom domain names, ensuring secure HTTPS connections without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Secrets Manager is for storing and rotating secrets such as database credentials and API keys, not for managing SSL/TLS certificates.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse AWS KMS or Secrets Manager with certificate management, but ACM is the only service that directly provisions and manages SSL/TLS certificates for use with AWS services like API Gateway and CloudFront.
Detailed technical explanation
How to think about this question
ACM integrates with API Gateway via the API Gateway REST API or HTTP API, where you associate a custom domain name with an ACM certificate ARN. ACM automatically handles certificate renewal for public certificates, but note that certificates must be in the same AWS Region as the API Gateway endpoint. For edge-optimized API endpoints, the certificate must be in us-east-1, while regional endpoints require the certificate in the same region as the API.
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.
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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
