What this domain covers

What to know about Zero Trust Architecture And Design

Be able to design identity-aware, posture-validated microsegmentation using User-ID, GlobalProtect HIP, and Panorama policy tools. The single most important thing: enforce least-privilege east-west access by combining user identity, device posture, and application-based rules, not network location alone.

User-ID mapping via PAN-OS agent, syslog parsing, and Panorama for identity-based policy

Panorama Policy Optimizer for rule cleanup, app usage, and unused rule identification

GlobalProtect with HIP profiles for continuous endpoint posture validation

Security zones and policy rules enforcing east-west microsegmentation between application tiers

Watch out for

Common Zero Trust Architecture And Design exam traps

  • ▸Assuming User-ID alone enforces Zero Trust without combining identity, posture, and microsegmentation controls
  • ▸Treating Policy Optimizer as a one-time cleanup rather than an ongoing rule hygiene process
  • ▸Confusing HIP profiles with host information collection agents, missing the enforcement side in policy
