CAS-004 Practice Question: Uses AWS, Azure, and GCP for different workloads
An organization uses AWS, Azure, and GCP for different workloads. They want a single tool to manage infrastructure consistently across all providers. Which approach is most appropriate?
⚠ Common exam trap
Candidates often mistakenly choose a single-vendor tool like CloudFormation or ARM templates for multi-cloud management. The correct approach uses a cloud-agnostic tool that abstracts provider APIs.

Correct answer & explanation
✓
Use Terraform with provider plugins
Terraform is an infrastructure-as-code tool that uses provider plugins to interact with the APIs of AWS, Azure, GCP, and hundreds of other services. This allows a single declarative configuration language (HCL) to manage resources consistently across all three cloud providers, making it the most appropriate choice for multi-cloud infrastructure management.
