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 S3 bucket with DynamoDB table for locking
Terraform supports remote backends like AWS S3 with DynamoDB for state locking, which provides both state storage and locking. Azure Blob Storage can also be used with blob lease locking.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
GitHub repository with Terraform Cloud agent
Why it's wrong here
GitHub is not a Terraform backend; Terraform Cloud is a separate service.
- ✗
Azure DevOps pipeline variable group
Why it's wrong here
Variable groups store environment variables, not Terraform state.
- ✓
AWS S3 bucket with DynamoDB table for locking
Why this is correct
S3 stores state; DynamoDB provides state locking, preventing concurrent operations.
- ✗
Local file system with .terraform.lock.hcl
Why it's wrong here
Local state does not support remote locking and is not suitable for team use.
