The answer is that you are currently inside a specific VDOM context. When you run `config vdom` and see multiple VDOMs listed, you are operating in the global configuration mode, which can see all VDOMs. However, the `show full-configuration` command is context-sensitive; it only outputs the configuration of the VDOM you are currently editing. If you have previously executed `edit <vdom-name>` within the `config vdom` tree, your CLI session is scoped to that single VDOM, so the full configuration output will be limited to that VDOM’s settings. This is a core concept tested on the Fortinet NSE 7 Advanced Security NSE7 exam, where the common trap is assuming `show full-configuration` always shows the global view. To avoid this, remember: `config vdom` is global, but `show full-configuration` is local. A quick memory tip: "Global list, local show"—the list command sees all, but the show command only sees where you stand.
NSE7 Enterprise Firewall and VDOMs Practice Question
This NSE7 practice question tests your understanding of enterprise firewall and vdoms. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 configures a FortiGate with VDOMs and notices that the 'config vdom' command lists multiple VDOMs, but only one VDOM is shown in the 'show full-configuration' output. What is the most likely reason?

Correct answer & explanation
✓
The administrator is in the context of a specific VDOM
The 'config vdom' command lists all VDOMs configured on the FortiGate because it operates in the global context. However, 'show full-configuration' only displays the configuration of the current VDOM context. If the administrator is inside a specific VDOM (e.g., after executing 'config vdom' and 'edit <vdom-name>'), the output is scoped to that VDOM, not the global configuration. This is a fundamental behavior of VDOM-based CLI navigation in FortiOS.
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.
✓
The administrator is in the context of a specific VDOM
Why this is correct
In VDOM mode, 'show full-configuration' shows only the current VDOM's config. The admin must be in the root VDOM to see all VDOMs.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The VDOMs are not properly synchronized
Why it's wrong here
This is not a sync issue.
✗
The VDOMs are not assigned any interfaces
Why it's wrong here
Even without interfaces, VDOMs would appear in the root VDOM config.
✗
The FortiGate is in transparent mode
Why it's wrong here
Transparent mode does not affect this behavior.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume 'config vdom' lists all VDOMs because they are all active, but they forget that 'show full-configuration' output is context-dependent and only reflects the current VDOM or global scope, not the entire device configuration.
Detailed technical explanation
How to think about this question
In FortiOS, the CLI context is tracked by the system via a VDOM index. When you execute 'config vdom' and 'edit <vdom-name>', the prompt changes (e.g., from 'FortiGate #' to 'FortiGate (vdom-name) #'), and all subsequent 'show' commands are scoped to that VDOM's configuration tree. The 'show full-configuration' command in a VDOM context outputs only the configuration relevant to that VDOM, omitting global settings and other VDOMs. This is analogous to how 'config system global' scopes commands to the global system settings.

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.
