NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator wants to use FortiManager to push a new firewall policy to a managed FortiGate. Before installing, the administrator wants to review what changes will be applied. Which FortiManager feature should be used?
⚠ Common exam trap
Watch out — candidates often confuse the Install Wizard (which guides the installation process) with Install Preview (which shows the actual changes), leading them to select Option B thinking it includes a review step, but the Install Wizard does not generate a detailed diff of pending modifications.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Install Preview
Install Preview (Option A) is the correct feature because it allows the administrator to see a detailed, side-by-side comparison of the current configuration on the managed FortiGate versus the pending changes that FortiManager will push. This preview is generated by FortiManager's policy compilation engine, which calculates the exact CLI commands and object modifications required to synchronize the device database (ADOM) with the managed FortiGate. It provides a safe, non-disruptive way to validate changes before committing them, reducing the risk of misconfiguration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Install Preview
Why this is correct
Install Preview compares the policy package on FortiManager against the managed FortiGate's current configuration, displaying exactly which changes the install would apply. This lets the administrator review the diff before committing, satisfying the requirement to inspect changes prior to installation.
- ✗
Policy & Objects - Install Wizard
Why it's wrong here
The Install Wizard performs the actual push to the managed FortiGate; it does not present a pre-install diff of pending changes. It is tempting because installation is the goal, but reviewing changes beforehand requires the Install Preview function instead.
- ✗
Configuration Rollback
Why it's wrong here
Configuration Rollback restores a previously saved FortiManager revision to a device; it does not preview pending policy differences. It is tempting because it also concerns configuration versions, but it applies historical states rather than showing what an install would change.
- ✗
Revision History
Why it's wrong here
Revision History records previously installed configuration versions for comparison or rollback, not the pending delta between FortiManager and the device. It is tempting because it shows configuration differences, but those are historical, not the changes an upcoming install would apply.
