Which of these is a PREDEFINED IAM role in Google Cloud?
- Any IP address inside the VPC CIDR
- A random hex string assigned at project creation
- `bucket-name/Standard/objects/*`
- `roles/storage.objectViewer`
Show answer and solution
Correct answer: D. `roles/storage.objectViewer`
Predefined roles use the `roles/<service>.<role>` convention (e.g. `roles/storage.objectViewer`, `roles/compute.instanceAdmin.v1`).
The other items are storage paths, identifiers, or IP ranges — not role names.
