The answer is that the two components which must be configured are a FortiToken assigned to the user and a user group that requires two-factor authentication. This is because FortiToken provides the second factor—a time-based, one-time password—while the first factor (typically a username and password) is handled by an external authentication server like LDAP or RADIUS; the user group policy acts as the enforcement point that mandates the token challenge. On the Fortinet NSE 4 Network Security Professional NSE4 exam, this question tests your understanding of how SSL VPN two-factor authentication is layered: the group setting triggers the requirement, and the token assignment supplies the cryptographic proof. A common trap is thinking the token alone is sufficient, but without the group requiring two-factor authentication, the FortiToken prompt never appears. Remember the memory tip: “Group gates, token turns”—the group setting is the gate that forces the token to turn the second factor on.
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.
An administrator wants to configure two-factor authentication for SSL VPN users. Which TWO components must be configured? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SSL VPN portal configured with 'require two-factor authentication'
FortiToken must be assigned to the user, and the user group must require two-factor authentication. The authentication server (LDAP/RADIUS) handles the first factor, FortiToken the second.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

✓
SSL VPN portal configured with 'require two-factor authentication'
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related NSE4 questions on access control and AAA configuration.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An administrator needs to deploy two-factor authentication for SSL VPN users. The company uses FortiTokens. Which two steps are required to enable FortiToken for SSL VPN users? (Choose two.)
medium
A.Install the FortiToken mobile app on the administrator's phone
B.Change the SSL VPN authentication scheme to RADIUS
✓ C.Configure two-factor authentication on the SSL VPN portal to require token code
✓ D.Assign the FortiToken to each user in the user database
Why C: FortiToken requires the user account to be associated with a FortiToken serial number, and the authentication method must be set to require token code along with password.
Variation 2. An administrator needs to configure two-factor authentication for SSL VPN users using FortiToken. Which configuration is required on the FortiGate?
medium
A.Enable two-factor authentication globally on the FortiGate
✓ B.Enable FortiToken on the user account and configure the authentication scheme to require token
C.Install the FortiToken mobile app on the FortiGate
D.Create a separate firewall policy for token-based authentication
Why B: FortiToken two-factor authentication requires the user account to have a FortiToken assigned. The user can then be required to enter a token code during authentication. The firewall policy itself must use an authentication scheme that enforces two-factor.
Variation 3. An administrator wants to enable two-factor authentication for SSL VPN users using FortiToken. Which configuration is required on the FortiGate?
medium
A.Create a RADIUS server pointing to FortiAuthenticator
B.Set the authentication timeout to 60 seconds
C.Configure SSL VPN to use certificate authentication
✓ D.Add the FortiToken to the user's account and enable 'fortitoken' in the user group
Why D: FortiToken two-factor authentication is enforced by enabling 'fortitoken' in the user group settings. The group must be added to the SSL VPN firewall policy.
