NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator wants to use FortiManager to deploy a common set of firewall rules to all VDOMs on a single FortiGate. The rules will be the same except for the source and destination addresses, which differ per VDOM. What FortiManager feature allows the administrator to reuse a policy package and customize per-VDOM objects?
⚠ Common exam trap
A common mix-up: candidates confuse Global ADOM with meta fields, thinking that global objects can be used to achieve per-VDOM customization, but Global ADOM only provides shared objects without variable substitution, whereas meta fields enable true per-VDOM customization within a single policy package.

Correct answer & explanation
✓
Meta fields
Meta fields in FortiManager allow you to define custom variables that can be assigned to managed devices or VDOMs. When a policy package is installed, these meta fields are substituted with the per-VDOM values, enabling the reuse of a single policy package with different source and destination addresses for each VDOM. This avoids the need to create separate policy packages for each VDOM.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Policy package header/footer
Why it's wrong here
Header/footer policies are used to add common policies at top/bottom of policy lists, not to customize objects.
- ✗
Automation stitches
Why it's wrong here
Automation stitches trigger actions, not policy customization.
- ✗
Global ADOM
Why it's wrong here
Global ADOM contains all devices but does not provide variable substitution.
- ✓
Meta fields
Why this is correct
Meta fields act as variables that can be populated per-device, allowing a common policy package to be installed with different object values.
