Bandwidth, application and risk reporting for management

Notification of policy change and configuration review

Tenant administration, roles and administrative separation

M7 — Deployment, Connectors and Migration

Planning a forwarding method for each site and population

Branch, remote and roaming user deployment patterns

Migrating from firewall and VPN to ZIA and ZPA in waves

Coexistence: running old and new paths without a double inspection

Validating the result against the original design intent

M8 — Capstone: Practice Exams and Tenant Build

A full timed practice exam under real conditions

Scoring by objective to isolate weak policy areas
