Option-by-option breakdown

- ✗
Rely solely on perimeter firewalls to block external attackers.
Why it's wrong here
Perimeter-only defense violates core Zero Trust methodology.

Inspect and log all traffic across all zones with least-privilege access control.
Why this is correct
Zero Trust requires strict inspection and least-privilege access for all traffic.
