NSE7 Advanced VPN and Zero Trust Practice Question
A FortiGate administrator is configuring ZTNA to protect an internal application and wants to ensure that only users who authenticate with a valid client certificate and whose devices pass posture checks can connect. The administrator has configured FortiClient EMS integration and a ZTNA access proxy rule. During testing, users without client certificates are still able to reach the application after providing username and password. Which setting should the administrator verify to enforce certificate-based authentication?
⚠ Common exam trap
The trap here is conflating EMS posture management or SSL VPN certificate settings with ZTNA client certificate enforcement, which lives in the access proxy rule’s authentication configuration.
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
✓
The ZTNA access proxy rule must require client certificate authentication in its authentication settings.
Client certificate enforcement for ZTNA is controlled by the access proxy rule’s authentication settings. The rule must be configured to require certificate authentication and reference the trusted CA that signed the client certificates. If the rule only permits password authentication, users without certificates can still authenticate, so the certificate requirement is effectively absent regardless of EMS or backend policy configuration.
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 firewall policy from the ZTNA server to the application must include a certificate-based user group.
Why it's wrong here
The backend firewall policy controls access after the proxy decapsulates traffic; it does not perform client certificate authentication for the ZTNA session. Certificate validation occurs at the access proxy during the client TLS handshake. Placing a certificate group on the backend policy would not stop password-authenticated users from reaching the proxy and being authorized.
- ✗
The SSL VPN settings must be configured to require client certificates for ZTNA users.
Why it's wrong here
ZTNA access proxy is distinct from SSL VPN, and SSL VPN certificate settings do not apply to ZTNA sessions. Configuring SSL VPN certificate requirements would affect VPN portals, not the ZTNA proxy authentication. The correct place to enforce client certificates for ZTNA is within the access proxy rule’s authentication options.
- ✓
The ZTNA access proxy rule must require client certificate authentication in its authentication settings.
Why this is correct
To enforce client certificates, the access proxy rule’s authentication configuration must explicitly require certificate authentication, typically by selecting the client certificate option and referencing the trusted CA. If only password authentication is enabled, users without certificates can still authenticate, so the certificate requirement is not enforced at the proxy.
- ✗
The FortiClient EMS connector must be configured to issue client certificates to endpoints.
Why it's wrong here
FortiClient EMS can manage endpoint compliance and tags, but it is not the component that enforces certificate authentication at the ZTNA proxy. Certificate issuance may come from a PKI or EMS, but enforcement happens in the access proxy rule. Without requiring certificates in the rule, issuing them does not prevent password-only users from connecting.
