Quick Answer
The answer is that the zone referenced in the policy is not yet created on the FortiGate. This error occurs because FortiManager performs a policy check before committing changes to ensure all referenced objects, such as zones, exist on the target device; if a policy like ID 5 uses a zone that the FortiGate has never received or had created locally, the commit fails to prevent a broken configuration. On the Fortinet NSE 7 Advanced Security NSE7 exam, this scenario tests your understanding of FortiManager’s consistency checks and the dependency between policy objects and device-level resources—a common trap is assuming the zone will be created automatically during the push, when in fact it must be pre-provisioned or installed separately. A useful memory tip is “zone first, policy last”: always ensure zone objects are installed on the FortiGate before pushing policies that reference them.
This NSE7 practice question tests your understanding of enterprise firewall and vdoms. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 sees the following error when trying to commit changes from FortiManager to a FortiGate: 'Policy check failed: Policy ID 5 uses a zone that does not exist on the device.' What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
The policy package is locked by another administrator
Why wrong: Locking prevents editing, not installation.
The FortiGate is not running the same firmware version as FortiManager
Why wrong: Firmware mismatch causes different errors.
The administrator has insufficient permissions
Why wrong: Permissions would cause a different error.

Correct answer & explanation
The zone referenced in the policy is not yet created on the FortiGate
The error 'Policy check failed: Policy ID 5 uses a zone that does not exist on the device' indicates that the FortiGate does not have the zone object referenced in the policy. When FortiManager pushes a policy that references a zone, the zone must already exist on the managed FortiGate; otherwise, the commit fails. Option B correctly identifies that the zone is missing on the FortiGate.
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.
The policy package is locked by another administrator
Why it's wrong here
Locking prevents editing, not installation.
The FortiGate is not running the same firmware version as FortiManager
Why it's wrong here
Firmware mismatch causes different errors.
The administrator has insufficient permissions
Why it's wrong here
Permissions would cause a different error.
Common exam traps
The trap here is that candidates may confuse a missing object error with a firmware version mismatch or permission issue, but the error message explicitly names the missing zone, making the root cause straightforward if read carefully.
Detailed technical explanation
FortiManager performs a pre-installation policy check to verify that all referenced objects (zones, addresses, services) exist on the target FortiGate. Zones are logical groupings of interfaces; if a zone is defined in the FortiManager policy but not yet created on the FortiGate (e.g., via a separate provisioning step or a previous install), the commit fails. In real-world scenarios, this often occurs when administrators create policies referencing zones that are part of a different ADOM or device group that hasn't been synchronized.
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 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.
