NSE4 System and Network Administration Practice Question
This NSE4 practice question tests your understanding of system and network administration. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A FortiGate administrator wants to ensure that all firewall policies are backed up before performing a firmware upgrade. Which backup method preserves the configuration in a format that can be restored to the same or different FortiGate model?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Backup the configuration via CLI using 'execute backup config tftp'
Option C is correct because 'execute backup config tftp' saves the FortiGate configuration in a plain-text, human-readable format that can be restored to the same or a different FortiGate model. This command backs up only the configuration (not firmware or logs) and is model-agnostic, allowing restoration across different hardware platforms as long as the firmware version is compatible.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use 'execute backup full-config tftp'
Why it's wrong here
This command does not exist; the correct command is 'execute backup config tftp'.
✗
Copy the configuration from the system config script
Why it's wrong here
Config scripts are not a backup format.
✓
Backup the configuration via CLI using 'execute backup config tftp'
Why this is correct
This backs up the full configuration in text format, which can be restored to any FortiGate.

✗
Save the running config from the GUI Dashboard
Why it's wrong here
The GUI does not provide a backup download feature.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing 'execute backup config tftp' with 'execute backup full-config tftp', where candidates mistakenly think a full backup is safer, not realizing it is model-specific and cannot be restored to a different FortiGate model.
Trap categories for this question
Command / output trap
This command does not exist; the correct command is 'execute backup config tftp'.
Detailed technical explanation
How to think about this question
The 'execute backup config tftp' command uses TFTP (Trivial File Transfer Protocol) to transfer the configuration file, which is stored as a plain-text script containing all CLI commands needed to recreate the configuration. This file can be edited manually and restored using 'execute restore config tftp', making it ideal for cross-model migrations. In contrast, a full-config backup includes the firmware image, which is tied to the specific hardware platform and cannot be applied to a different model due to differences in kernel and driver support.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
