The correct answer is to perform a full configuration backup, review the release notes for the target firmware version, and verify the upgrade path from FortiOS 6.0 to 7.2. These three steps are critical because the release notes document deprecated features, changed default behaviors, and mandatory pre-upgrade actions—such as disabling certain security profiles or adjusting hardware compatibility—that prevent service disruptions or feature loss. On the Fortinet NSE 4 Network Security Professional exam, this scenario tests your understanding of the firmware upgrade lifecycle, often appearing as a multi-select question where a common trap is to overlook the upgrade path requirement, assuming a direct jump is supported. Remember that skipping the release notes can lead to unexpected failures, as they explicitly list any required intermediate versions or configuration changes. A useful memory tip is “Backup, Notes, Path”—always secure your config, read the target version’s notes, and confirm the sequential upgrade route.
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.
An administrator is planning a firmware upgrade from FortiOS 6.0 to 7.2. Which THREE steps should be performed before starting the upgrade process?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Read the release notes for the target firmware version
Reading the release notes for the target firmware version (FortiOS 7.2) is essential because they document critical upgrade-specific information, such as deprecated features, changed default behaviors, known issues, and hardware compatibility requirements. Skipping this step can lead to unexpected service disruptions or feature loss after the upgrade, as the release notes often include mandatory pre-upgrade actions like disabling certain features or adjusting configurations.
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.
✓
Read the release notes for the target firmware version
Why this is correct
Release notes contain important upgrade instructions and known issues.

✗
Remove all static routes to avoid routing issues
Why it's wrong here
Routes are preserved; removing them would cause connectivity loss.
✓
Verify the upgrade path and ensure intermediate versions are used if needed
Why this is correct
Major version jumps may require intermediate upgrades.
Related concept

✓
Perform a full configuration backup
Why this is correct
Always back up before upgrade.

✗
Disable all antivirus and IPS sensors
Why it's wrong here
Not required and may cause security gaps.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think disabling security features (Option E) is a safe precaution, but Fortinet explicitly advises against disabling security profiles unless a specific release note entry warns of a conflict, making it a distractor that wastes time and reduces security posture.
Detailed technical explanation
How to think about this question
FortiOS firmware upgrades follow a strict upgrade path defined by Fortinet, often requiring intermediate versions (e.g., 6.0.x to 6.2.x to 6.4.x to 7.0.x to 7.2.x) to ensure configuration compatibility and avoid boot loops. The configuration backup (Option D) should include the full system configuration, including firewall policies, VPN settings, and routing tables, as a rollback may require restoring from a backup if the upgrade fails or introduces incompatibilities. The release notes (Option A) also specify any required pre-upgrade commands, such as 'execute upgrade-rc' or 'execute update-rc', which clear the root-cause database to prevent corruption during the upgrade.

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.
