Quick Answer
The answer is using the GUI under System > Firmware and the CLI command 'execute upgrade image tftp <ip> <filename>'. These two methods are valid because the FortiGate firmware upgrade process is officially supported through both the graphical interface for point-and-click file uploads and the command-line interface for TFTP-based image retrieval, ensuring flexibility across different administrative environments. On the Fortinet NSE 4 Network Security Professional exam, this question tests your understanding of supported upgrade paths versus unsupported shortcuts like using FTP or SCP directly, which are common traps. A frequent trick is that while you can download firmware via HTTP, the actual upgrade command must specify TFTP, not HTTP. Remember the memory tip: "GUI for local, TFTP for remote" — the CLI command always requires a TFTP server, never a web server.
This NSE4 practice question tests your understanding of system and network administration. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are valid methods to upgrade the FortiGate firmware? (Choose two.)
Use the GUI under System > Firmware.
GUI provides a firmware upgrade option.
Use the command 'execute upgrade image tftp <ip> <filename>'.
This upgrades firmware from TFTP.
Use the command 'execute backup config tftp'.
Why wrong: This backs up config, not upgrade firmware.
Use the command 'execute reboot'.
Why wrong: This reboots, does not upgrade.
Use the command 'execute restore config tftp'.
Why wrong: This restores config, not firmware.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use the GUI under System > Firmware.
Option A is correct because the FortiGate GUI provides a dedicated interface under System > Firmware to upload and install firmware images, which is a standard and supported upgrade method. This method allows administrators to select a local or remote firmware file and apply it with minimal disruption when proper procedures are followed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Use the GUI under System > Firmware.
Why this is correct
GUI provides a firmware upgrade option.

Use the command 'execute upgrade image tftp <ip> <filename>'.
Why this is correct
This upgrades firmware from TFTP.
Related concept
Read the scenario before looking for a memorised answer.
Use the command 'execute backup config tftp'.
Why it's wrong here
This backs up config, not upgrade firmware.
Use the command 'execute reboot'.
Why it's wrong here
This reboots, does not upgrade.
Use the command 'execute restore config tftp'.
Why it's wrong here
This restores config, not firmware.
Common exam traps
The trap here is that candidates may confuse backup/restore or reboot commands with firmware upgrade commands, or incorrectly assume that only GUI-based methods are valid, while the TFTP upgrade command is also a legitimate and commonly tested method.
Detailed technical explanation
Firmware upgrades on FortiGate involve replacing the system image stored in the flash memory, typically using TFTP, FTP, or HTTP/HTTPS protocols. The command 'execute upgrade image tftp <ip> <filename>' (Option B) triggers the TFTP client to download and install the firmware image directly, bypassing the GUI. In real-world scenarios, TFTP is often used for remote upgrades when GUI access is unavailable, but it requires careful TFTP server configuration and network connectivity.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the NSE4 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
