The answer is to use the Revision History feature to compare the current configuration with the previous version. This is correct because Revision History provides a detailed diff view, showing exactly which policies will be added, removed, or modified, allowing an administrator to verify exact policy changes before install FortiManager pushes the configuration to the FortiGate. On the Fortinet NSE 7 Advanced Security NSE7 exam, this question tests your understanding of configuration management workflows, specifically the distinction between the Install Preview, which only flags that changes exist, and Revision History, which reveals the precise modifications. A common trap is assuming the Install Preview itself shows the diff, but it does not—it only indicates a delta exists. Memory tip: think of Revision History as a “before-and-after snapshot” for your policy package, giving you the granular diff you need to confirm every change before committing to installation.
NSE7 Enterprise Firewall and VDOMs Practice Question
This NSE7 practice question tests your understanding of enterprise firewall and vdoms. 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 notices that after making changes to a policy package in FortiManager, the 'Install Preview' shows that the changes will modify policies on a FortiGate. However, the admin wants to verify what the exact changes will be before installing. What should the admin do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'Revision History' to compare the current configuration with the previous version
Option C is correct because the Revision History feature in FortiManager allows an administrator to compare the current configuration of a policy package with a previous version, showing a detailed diff of exactly which policies will be added, removed, or modified. This provides a precise verification of changes before installation, unlike the Install Preview which only indicates that changes exist without showing the specific modifications.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Check the 'Audit Log' for recent changes
Why it's wrong here
Audit log shows who made changes, not the exact configuration differences.
✗
Run 'diagnose dvm device list' on FortiManager
Why it's wrong here
This command lists devices, not configuration differences.
✓
Use the 'Revision History' to compare the current configuration with the previous version
Why this is correct
Revision history allows comparing configurations to see exact changes.

✗
Use the 'Install Preview' and then click 'View Details' on each device
Why it's wrong here
Install Preview shows summary, not detailed diff.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the Install Preview's summary of changes (which only indicates that modifications exist) with the detailed comparison provided by Revision History, leading them to select Option D without realizing it lacks the granular diff needed to verify exact policy changes.

Detailed technical explanation
How to think about this question
FortiManager's Revision History stores snapshots of policy packages and ADOM databases, allowing administrators to select two revisions and generate a 'diff' report that highlights added, deleted, and changed policies with specific attribute-level details (e.g., source/destination addresses, schedules, NAT settings). This is critical in multi-admin environments where concurrent changes can cause conflicts, and the diff ensures that only intended modifications are pushed to FortiGate devices, preventing service disruptions.

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 practitioner preparing for the NSE7 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.
