The correct answer is to wait for the lock to be released automatically. This is the safest approach because Terraform uses state locking to prevent concurrent modifications that could corrupt the state file; when one engineer is running `terraform plan`, it acquires a read lock, and `terraform apply` requires a write lock, so the apply command must queue until the plan completes and releases its lock. On the HashiCorp Terraform Associate TF-003 exam, this scenario tests your understanding of state locking mechanics and the principle that force-unlocking should only be used when the lock holder has clearly crashed or been terminated, not when another process is still active. A common trap is assuming you can force-unlock immediately or disable locking, but both risk state corruption or race conditions. Remember the memory tip: "Lock first, unlock last—never force a lock that’s still held fast."
TF-003 Implement and maintain state Practice Question
This TF-003 practice question tests your understanding of implement and maintain state. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 developer runs `terraform apply` and receives the error: 'Error acquiring the state lock'. Another engineer is currently running `terraform plan`. What should the developer do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Wait for the lock to be released automatically
The safest action is to wait for the lock to be released. Force-unlocking without proper cause can corrupt the state, and disabling locks can cause concurrency issues.
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.
✗
Run terraform init to reinitialize the backend
Why it's wrong here
Reinitializing does not release an active lock.
✓
Wait for the lock to be released automatically
Why this is correct
The lock will be released when the other engineer's plan completes. Waiting is the safest approach.
Related concept
Read the scenario before looking for a memorised answer.
✗
Run terraform force-unlock with the lock ID
Why it's wrong here
Force-unlock should only be used when the lock holder is known to be dead; here, another engineer is actively running a plan.
✗
Run terraform plan with -lock=false to bypass the lock
Why it's wrong here
Disabling the lock is unsafe and can lead to concurrent writes and state corruption.
✗
Delete the lock file from the S3 bucket
Why it's wrong here
Manually deleting the lock file can corrupt state and is not recommended.
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.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
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 practitioner preparing for the TF-003 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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A user runs `terraform apply` and receives an error: 'Error acquiring the state lock'. What is the most likely cause?
easy
✓ A.Another user is running a Terraform command that modifies state.
B.The state file is missing.
C.The backend configuration is invalid.
D.The Terraform provider is incompatible.
Why A: The error indicates another operation holds the state lock. Option B is correct because only one user can modify state at a time. Option A is incorrect because missing state file would cause a different error. Option C is incorrect because backend configuration errors appear during init, not apply. Option D is incorrect because provider incompatibility causes plugin errors.
