TF-003 Implement and maintain state Practice Question
This TF-003 practice question tests your understanding of implement and maintain state. 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.
Exhibit
Error: Backend initialization required: please run "terraform init"
Reason: Backend configuration has changed.
The configured backend "s3" has changed since the last "terraform init".
Previous configuration:
bucket = "prod-terraform-state"
key = "network/terraform.tfstate"
region = "us-east-1"
New configuration:
bucket = "prod-terraform-state"
key = "network/terraform.tfstate"
region = "us-west-2"
Refer to the exhibit. A developer runs terraform plan and receives this error. What should the developer do to resolve the error?
Error: Backend initialization required: please run "terraform init"
Reason: Backend configuration has changed.
The configured backend "s3" has changed since the last "terraform init".
Previous configuration:
bucket = "prod-terraform-state"
key = "network/terraform.tfstate"
region = "us-east-1"
New configuration:
bucket = "prod-terraform-state"
key = "network/terraform.tfstate"
region = "us-west-2"
A
Run terraform plan again; the error will self-resolve after a few minutes.
Why wrong: The error will not self-resolve; manual reinitialization is required.
B
Run terraform init -migrate-state to migrate the state to the new region.
This command reinitializes the backend and migrates the existing state to the new backend configuration.
C
Update the backend configuration in the Terraform code to match the previous region.
Why wrong: Reverting the configuration would avoid the problem but does not address the desired change to us-west-2.
D
Run terraform state rm to remove the state file and start fresh.
Why wrong: Removing state is destructive and not necessary; the state can be migrated.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run terraform init -migrate-state to migrate the state to the new region.
The error indicates that the backend configuration has changed (the region changed from us-east-1 to us-west-2). Terraform requires re-initialization when backend configuration changes.
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
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.
