CV0-004 Deployment Practice Question
A company uses Terraform to manage infrastructure as code. After running terraform apply, the state file is stored locally. The team wants to enable collaboration by storing state remotely with locking to prevent concurrent modifications. Which backend should be configured?
⚠ Common exam trap
A common mix-up: candidates choose Consul or HTTP thinking they support locking, but CompTIA Cloud+ tests the specific requirement for a fully managed, AWS-native solution with built-in locking, which only S3 with DynamoDB provides among the options.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
S3 with DynamoDB locking
S3 provides a scalable, durable remote backend for Terraform state, and DynamoDB locking prevents concurrent modifications by acquiring a lock via a DynamoDB table before state operations. This combination is the standard AWS-native solution for team collaboration, as it supports state versioning, encryption, and consistent locking via DynamoDB's conditional writes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Consul
Why it's wrong here
Consul can be a backend but is less common; S3 with DynamoDB is typical.
- ✗
HTTP
Why it's wrong here
HTTP backend is possible but less common and doesn't natively support locking.
- ✓
S3 with DynamoDB locking
Why this is correct
S3 backend with DynamoDB table for locking is a standard approach for team collaboration.
- ✗
local
Why it's wrong here
Local backend stores state on disk, no remote sharing.
