Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a network firewall policy and attach it to each VPC
Why it's wrong here

Why this is correct
Hierarchical policies can be applied to the organization, folder, or project for consistent enforcement.
- ✗
