In FortiManager, what is the result of using the 'Re-install Policy' option instead of the 'Install Wizard'?
Re-install Policy re-pushes the policy package using the installation parameters stored from the previous install, without prompting for target device or scope. This satisfies the scenario's requirement to repeat a deployment quickly, whereas the Install Wizard forces you to reselect devices and options each time.
Why this answer
'Re-install Policy' in FortiManager re-pushes the last successfully installed policy package and configuration to the managed FortiGate using the saved installation parameters (target device, ADOM, and revision). It does not run the full Install Wizard again, so it is faster and preserves the prior install scope. This is useful when a device was restored or a config drift needs to be corrected without re-selecting targets.
Exam trap
FORTINET-NSE56 often tests the confusion between 'Re-install Policy' (replay last install) and 'Install Wizard' (new install with target selection), tricking candidates into thinking re-install resets or upgrades the device.
How to eliminate wrong answers
Option A is wrong because 'Re-install Policy' does not factory-reset a FortiGate; factory reset is a separate device action and would wipe the config, which is not what re-install does. Option B is wrong because unused object cleanup is a separate FortiManager feature (e.g., 'Delete Unused Objects' or ADOM cleanup), not part of re-install. Option D is wrong because firmware upgrades are handled by FortiManager's firmware management or FortiGuard upgrade features, not by re-installing a policy package.
