Exhibit
Refer to the exhibit.
```
{
"bindings": [
{
"role": "roles/bigquery.dataViewer",
"members": [
"serviceAccount:dataflow-worker@PROJECT_ID.iam.gserviceaccount.com"
]
}
]
}
```The exhibit shows an IAM policy for a BigQuery dataset. A Dataflow job is failing with 'Access Denied: Table ... User does not have bigquery.tables.get permission'. Which additional role should be granted to the service account?
⚠ Common exam trap
Google Cloud often tests the misconception that `roles/bigquery.user` or `roles/bigquery.jobUser` provide sufficient read access for Dataflow jobs, when in fact they lack the specific `bigquery.tables.get` permission needed for table metadata retrieval.

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
✓
roles/bigquery.dataEditor
The error indicates the service account lacks the `bigquery.tables.get` permission, which is required to read table metadata. `roles/bigquery.dataEditor` includes this permission along with `bigquery.tables.get`, `bigquery.tables.update`, and `bigquery.tables.export`, making it the minimal role that resolves the access denied error for a Dataflow job reading from a BigQuery table.
