Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Grant permissions to user groups rather than attaching policies directly to individual users.
Why this is correct
Managing access via groups simplifies user onboarding and role management.
- ✓
Apply the principle of least privilege when writing IAM policies.
Why this is correct
Users and groups should only be given the exact permissions required to perform their jobs.
- ✓
Keep compartment hierarchies relatively shallow (typically <= 6 levels).
Why this is correct
Shallow compartment hierarchies prevent policy inheritance complexity and administrative overhead.
- ✗
Share tenancy root administrative credentials among all team members.
Why it's wrong here
Sharing root credentials is a severe security violation; individual accounts and least-privilege groups must be used.
- ✗
Write all IAM policies at the root tenancy level to avoid managing multiple policies.
Why it's wrong here
Writing all policies at the root violates least privilege and centralizes administrative complexity unnecessarily.
