Question 746 of 1,000

Authentication and VPN →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is to configure 'URL Access' under the SSL VPN portal settings. This setting is specifically designed for web mode to restrict users to a single internal web application, such as https://internal-app.company.local, by defining an explicit allow list of URLs; any URL not listed is automatically blocked, ensuring users cannot navigate elsewhere. On the Fortinet NSE 4 Network Security Professional NSE4 exam, this concept tests your understanding of SSL VPN web mode granular access control, often appearing as a scenario where you must differentiate between 'URL Access' and broader options like 'Split Tunneling' or 'Port Forwarding'—a common trap is confusing URL Access with the portal’s 'Allowed User Groups' or 'Web Mode' toggle, which do not restrict specific destinations. Remember the memory tip: "URL Access locks the path, not the portal."

NSE4 Authentication and VPN Practice Question

This NSE4 practice question tests your understanding of authentication and vpn. 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 is configuring an SSL VPN web mode portal. The administrator wants users to access only a specific internal web application (https://internal-app.company.local) and nothing else. Which SSL VPN setting should be configured to achieve this?

Question 1mediummultiple choice

Read the full VPN explanation →

A
In the SSL VPN portal, set the default bookmark to the application URL
Why wrong: Setting a default bookmark only provides a shortcut; users could still modify the URL and access other resources if not restricted.
B
Configure a firewall policy that allows traffic only to the application's IP address
Why wrong: Firewall policies can restrict network access, but in web mode, the user's traffic originates from the FortiGate's IP, so policy would need to be for outgoing traffic from the FortiGate, which is less direct.
C
Enable split tunneling under the SSL VPN settings
Why wrong: Split tunneling controls routing, but in web mode, it doesn't restrict which web applications can be accessed; it's more relevant for tunnel mode.
D
Under the SSL VPN portal, configure 'URL Access' to allow only https://internal-app.company.local
URL Access in the SSL VPN portal restricts which web addresses users can browse. Only the specified URLs are accessible.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Under the SSL VPN portal, configure 'URL Access' to allow only https://internal-app.company.local

Option D is correct. In web mode, 'URL Access' allows the administrator to specify which URLs users can access. By adding only the desired application URL, the administrator restricts access to that application only.

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.

✗
In the SSL VPN portal, set the default bookmark to the application URL
Why it's wrong here

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
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 NSE4 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.
