NSE7 Enterprise Firewall and VDOMs Practice Question
A FortiGate is managed by FortiManager. The administrator creates a new policy package for VDOM 'Sales' and installs it. Later, they find that the previous configuration has been overwritten. What should the administrator do to avoid this in the future?
⚠ Common exam trap
It's easy for candidates to confuse revision history (which is post-hoc) with install preview (which is proactive), or mistakenly think auto-lock prevents overwrites when it only serializes administrative edits.
Answer choices
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
✓
Use the install preview before applying the changes
Using the install preview allows the administrator to review the exact changes that will be applied to the FortiGate before committing them. This prevents accidental overwrites by showing a diff of the configuration, enabling the administrator to verify that the new policy package will not replace existing settings unintentionally.
