The answer is to use the Terraform force-unlock command with the lock ID. This is correct because the DynamoDB lock item persists even after the Terraform process that created it has crashed or been terminated, creating a stale lock that blocks any new operations. The force-unlock command directly removes that stale lock item from the DynamoDB table, allowing the pipeline to acquire a fresh lock and proceed with the deployment. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of Terraform state management in a multi-account environment, specifically how to handle broken locks without risking state corruption. A common trap is to delete the state file or manually edit DynamoDB, but the safe, supported method is always force-unlock. Memory tip: think of force-unlock as a "break glass" tool—use it only when you are certain no other process holds the lock, and always verify the lock ID matches the stale entry.
DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 a multi-account AWS environment. The Terraform state files are stored in an S3 bucket with DynamoDB locking. Recently, a DevOps engineer ran 'terraform apply' from a CI/CD pipeline, and it failed with the error: 'Error acquiring the state lock. Lock ID: "abc123". Possible causes: Another process has the lock; or a previous process crashed.' The engineer checks DynamoDB and sees that the lock item exists but there is no active Terraform process. The engineer needs to proceed with the deployment urgently. What should the engineer do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'terraform force-unlock' command with the lock ID to remove the lock.
Option C is correct because force-unlock removes the lock item, allowing the pipeline to proceed. Option A is wrong because waiting may be futile if no process holds the lock. Option B is wrong because deleting the state file would cause data loss. Option D is wrong because manual editing of state is risky and unnecessary.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use the 'terraform force-unlock' command with the lock ID to remove the lock.
Why this is correct
Force-unlock is designed for this situation when no process holds the lock.
Related concept
Read the scenario before looking for a memorised answer.
✗
Wait for the lock to expire automatically.
Why it's wrong here
DynamoDB locks do not expire; they persist until removed.
✗
Delete the state file from S3 and recreate it from the last backup.
Why it's wrong here
This would cause loss of current state and is not recommended.
✗
Manually delete the lock item from DynamoDB using the AWS Console.
Why it's wrong here
While this works, Terraform's force-unlock is the proper tool and logs the action.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

TExam Day Tips
→Underline the problem statement mentally.
→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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
