- A
Remove the DynamoDB table and use local state files to avoid locking issues.
Why wrong: Local state removes locking and can cause corruption with concurrent operations.
- B
Configure all team members to use the same workspace so that only one person can apply at a time.
Why wrong: This reduces parallelism and defeats workspace isolation.
- C
Keep the current setup because the error is harmless and users can retry.
Why wrong: The error is expected but does not prevent concurrent operations; however, this is not the best approach as it causes friction.
- D
Use separate state files per workspace and ensure each workspace has its own lock entry in DynamoDB; the current setup already supports this.
Workspaces use separate state files and DynamoDB locks per state file, allowing concurrent operations on different workspaces.
TF-003 Understand IaC concepts Practice Question
This TF-003 practice question tests your understanding of understand iac concepts. 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 company uses Terraform to manage infrastructure on AWS. They have a configuration that creates an S3 bucket and a DynamoDB table for state locking. The team notices that sometimes when two members run terraform apply simultaneously, they get a state locking error. However, they want to allow concurrent operations on different workspaces. What is the best approach?

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
Use separate state files per workspace and ensure each workspace has its own lock entry in DynamoDB; the current setup already supports this.
Option D is correct because Terraform natively supports per-workspace state files, and when using a remote backend like S3 with DynamoDB for state locking, each workspace's state file is stored at a distinct path in S3. The DynamoDB lock entry is tied to the specific state file path via the LockID, so concurrent operations on different workspaces acquire separate locks and do not conflict. This setup allows multiple team members to run terraform apply simultaneously as long as they are working in different workspaces.
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
HashiCorp often tests the misconception that DynamoDB locking is global across all workspaces, when in fact the lock is scoped to the specific state file path, which includes the workspace name.
Detailed technical explanation
How to think about this question
Under the hood, the S3 backend uses the DynamoDB table with a primary key called LockID, which is constructed as <bucket>/<state_file_path>/<workspace_name>. When Terraform acquires a lock, it writes a DynamoDB item with this LockID; if another operation tries to lock the same state file path, the PutItem call fails due to the conditional expression. For different workspaces, the state file paths differ (e.g., env:/prod vs env:/dev), so the LockID values are distinct, allowing simultaneous locks. A real-world scenario is a CI/CD pipeline where multiple branches deploy to separate workspaces; this setup enables parallel deployments without lock contention.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
