The answer is that you must define the RADIUS server under User & Authentication > RADIUS Servers and then create a user group that references that server as the authentication method. This is because the FortiGate does not directly bind a RADIUS server to an SSL VPN portal; instead, the user group acts as the intermediary object that maps the external authentication source to the VPN tunnel. On the Fortinet NSE 7 Advanced Security NSE7 exam, this concept tests your understanding of how authentication flows are chained—a common trap is thinking that simply adding the RADIUS server to the firewall policy is enough, but without the user group, the FortiGate has no way to forward the RADIUS challenge. A reliable memory tip is to remember the chain: Server → Group → Portal/Policy; if any link is missing, authentication fails.
NSE7 Advanced VPN and Zero Trust Practice Question
This NSE7 practice question tests your understanding of advanced vpn and zero trust. 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.
Which TWO configurations are required to enable SSL VPN authentication using a RADIUS server on a FortiGate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a user group that includes the RADIUS server as an authentication method
Option A is correct because a user group must be created to reference the RADIUS server as an authentication method. This group is then applied to the SSLVPN portal or firewall policy, allowing FortiGate to forward authentication requests to the RADIUS server. Without the user group, the RADIUS server cannot be associated with SSL VPN authentication.
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.
✓
Create a user group that includes the RADIUS server as an authentication method
Why this is correct
A user group ties the RADIUS server to SSLVPN authentication.

Read the scenario before looking for a memorised answer.
✗
Configure an LDAP server to synchronize user accounts
Configure an SSL VPN portal with 'Require Authentication' enabled
Why it's wrong here
Portal settings don't specify the authentication method.
✓
Define the RADIUS server under User & Authentication > RADIUS Servers
Why this is correct
The RADIUS server must be defined before it can be used.

✗
Set a local password policy for SSL VPN users
Why it's wrong here
Password policy is not required; RADIUS handles passwords.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think configuring the RADIUS server alone is sufficient, but FortiGate requires the user group to link the RADIUS server to the SSLVPN authentication process.
Detailed technical explanation
How to think about this question
When a RADIUS server is configured under User & Authentication > RADIUS Servers, FortiGate acts as a RADIUS client (NAS) using the RADIUS protocol (RFC 2865). The user group binds the RADIUS server as an authentication method, and during SSLVPN login, FortiGate sends an Access-Request packet to the RADIUS server; a successful Access-Accept response allows the user to connect. In real-world deployments, RADIUS can also return attributes like tunnel-group or filter-id to dynamically assign SSL VPN policies.

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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
