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
✓
Upload the firmware image first, then confirm the upgrade, then reboot.
Firmware upgrade requires uploading the image and confirming; the device reboots automatically.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Upload the firmware image first, then confirm the upgrade, then reboot.
Why this is correct
The upgrade sequence on FortiGate is strictly ordered: the firmware image must be staged on the device first, typically via GUI or `execute restore`/`execute upgrade` in the CLI. Only after the image is present does the confirmation step initiate the installation and set the active partition for the next boot. Rebooting then loads the newly installed firmware, so this order ensures the image is both available and selected before the device restarts.
- ✗
Confirm the upgrade first, then upload the firmware image, then reboot.
Why it's wrong here
This order is impossible because the confirmation command or GUI step requires a firmware image to be already uploaded to the device. Without an image staged, the FortiGate will report an error or prompt for a file, so the confirmation cannot proceed. Even if you force a confirmation command, it will fail because the source image is absent, making this sequence technically invalid.
- ✗
Upload the firmware image first, then reboot, then confirm the upgrade.
Why it's wrong here
Uploading the image to the device stores it in a temporary staging area, but the running firmware is never modified by the upload alone. If you reboot at this point, the FortiGate restarts with the same firmware it was already running, and the staged image is discarded or remains pending without activation. The confirmation step is what marks the image as the one to install on reboot, so omitting it before reboot means the upgrade never actually begins.
- ✗
Reboot first, then upload the firmware image, then confirm the upgrade.
Why it's wrong here
A reboot performed before any firmware upload simply restarts the FortiGate with its current, already-installed firmware—it has no effect on upgrading. Even if you later upload the image and confirm the upgrade, the initial reboot is pointless and adds no value to the process. The correct order would require the upload and confirmation to happen before any reboot, otherwise the reboot cannot apply a firmware that hasn't been staged or selected.
