CV0-004 Deployment Practice Question
This CV0-004 practice question tests your understanding of deployment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 DevOps team uses Terraform to manage cloud infrastructure. They want to store the state file in a remote backend to enable team collaboration. Which backend configuration stores Terraform state in an S3 bucket?
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
✓
backend 's3'
Option C is correct because Terraform's 's3' backend is specifically designed to store state files in an AWS S3 bucket, enabling team collaboration through remote state locking and versioning. This backend uses the AWS SDK to interact with S3, supporting features like DynamoDB-based state locking and encryption with KMS.
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
Cisco often tests the specific backend names mapped to cloud providers, and the trap here is that candidates may confuse 's3' with a generic storage term or assume 'azurerm' or 'gcs' are interchangeable, when each is tied to a distinct cloud platform.
Detailed technical explanation
How to think about this question
The 's3' backend leverages S3's eventual consistency model for state storage, but uses DynamoDB for strong consistency in state locking via the 'dynamodb_table' argument. In real-world scenarios, teams must configure S3 bucket versioning and lifecycle policies to prevent state corruption and enable rollback, as Terraform state files are critical for infrastructure drift detection.
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 practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
