The answer is to grant the Storage Object Viewer role to the service account on the GCS bucket. This error occurs because Terraform’s remote backend in GCS requires read access to the state file stored in the bucket, and the service account used by the developer lacks the `storage.objects.get` permission. The `Storage Object Viewer` role provides exactly that read-only access, allowing `terraform plan` to fetch the current state without needing write permissions. On the HashiCorp Terraform Associate TF-003 exam, this scenario tests your understanding of remote backend authentication and IAM least privilege—a common trap is confusing viewer with object admin roles or assuming the error is a local credential issue. Remember the memory tip: “Plan needs to peek, not write,” so for `terraform plan`, always think read-only access like Storage Object Viewer.
TF-003 Implement and maintain state Practice Question
This TF-003 practice question tests your understanding of implement and maintain state. 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 new developer joins a project that uses Terraform with a remote backend in GCS (Google Cloud Storage). They clone the repository and run `terraform init` successfully. However, when they run `terraform plan`, they get an error: "Error loading state: AccessDenied: 403 my-project-terraform-state@my-project.iam.gserviceaccount.com does not have storage.objects.get access to the Google Cloud Storage bucket." What is the most likely resolution?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Grant the `Storage Object Viewer` role to the service account on the GCS bucket
The error indicates the service account used by Terraform lacks read access to the GCS bucket. Option B correctly addresses granting IAM permissions.
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.
✗
Disable access control on the bucket temporarily
Why it's wrong here
Not a secure solution; the issue is missing permissions.
✗
Run `terraform init -reconfigure` to regenerate the backend configuration
Why it's wrong here
Init does not grant permissions.
✓
Grant the `Storage Object Viewer` role to the service account on the GCS bucket
Why this is correct
This allows the service account to read the state file.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Change the backend to local state and commit the state to the repository
Why it's wrong here
Local state defeats collaboration and should not be committed.
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 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.
