Quick Answer
The answer is split tunneling. This is the correct choice because split tunneling allows the VPN to route only traffic destined for specific internal applications through the encrypted tunnel, while all other internet-bound traffic bypasses the VPN and goes directly to the user’s local gateway. On the Fortinet NSE 4 Network Security Professional exam, this concept tests your understanding of how to configure SSL VPN split tunneling for specific applications without granting full network access—a common scenario for remote access policies. A frequent trap is confusing split tunneling with full tunneling, where all traffic goes through the VPN; remember that split tunneling is the opposite, conserving bandwidth and reducing latency for non-corporate traffic. For the exam, think of it as “split the path, not the access”—only the routes you define, such as a specific application server IP, are forced through the VPN tunnel, ensuring security without overburdening the corporate network.
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.
An admin needs to configure an SSL VPN for remote users that only provides access to specific internal applications, not full network access. What feature should be configured?
Full tunneling
Why wrong: Full tunneling sends all traffic through the VPN, providing full network access.
Client certificate authentication
Why wrong: This is an authentication method, not access control.
Split tunneling
Split tunneling allows the admin to define which subnets are accessible via VPN.
Web mode portal
Why wrong: Web mode provides access to web applications only, not necessarily specific internal apps.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Split tunneling
Split tunneling with specific routes ensures only traffic destined for internal applications goes through the VPN, and all other traffic goes directly to the internet.
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.
Full tunneling
Why it's wrong here
Full tunneling sends all traffic through the VPN, providing full network access.
Client certificate authentication
Why it's wrong here
This is an authentication method, not access control.
Split tunneling
Why this is correct
Split tunneling allows the admin to define which subnets are accessible via VPN.

Why it's wrong here
Web mode provides access to web applications only, not necessarily specific internal apps.
Common exam traps
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
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.
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 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.
