NSE7 Advanced VPN and Zero Trust Practice Question
A company is deploying ZTNA to replace their legacy VPN. They want to ensure that only users with a valid certificate and compliant antivirus can access the internal application. Which TWO components are required on the FortiGate for this deployment?
⚠ Common exam trap
NSE7 often tests the confusion between ZTNA components and legacy VPN components, causing candidates to select SSL-VPN or IPsec options instead of the required ZTNA proxy rule and ZTNA tag-based firewall policy.

Correct answer & explanation
✓
ZTNA proxy rule with access proxy
Option A is correct because the ZTNA proxy rule with an access proxy is the FortiGate component that publishes the internal application and enforces the ZTNA access proxy, which is where client certificate authentication and device posture (such as compliant antivirus) are validated before traffic is allowed. Option C is correct because a firewall policy with ZTNA tags matching is required to permit and control the traffic from ZTNA-authenticated users, using the dynamic ZTNA tags that FortiClient EMS assigns based on certificate and antivirus compliance. Together, the access proxy handles the ZTNA authentication and posture check, while the firewall policy with ZTNA tag matching authorizes the session to the internal application. Option B is not required because BGP is a dynamic routing protocol unrelated to ZTNA access control. Option D is not required because SSL-VPN portal is the legacy VPN feature being replaced by ZTNA. Option E is not required because IPsec phase1 with certificate authentication is a site-to-site or remote VPN tunnel mechanism, not the ZTNA access proxy enforcement used here.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
ZTNA proxy rule with access proxy
Why this is correct
The access proxy defines the protected internal application and terminates ZTNA traffic, enforcing certificate and posture checks before forwarding. Without this proxy rule on the FortiGate, no ZTNA policy can validate the user certificate and compliant antivirus required by the stem.
- ✓
Firewall policy with ZTNA tags matching
Why this is correct
The firewall policy matches ZTNA tags to permit or deny traffic, so only endpoints whose tags confirm valid certificate and compliant antivirus reach the internal application. This enforces the stem's dual condition at the policy level, complementing the access proxy configuration.
Quick reference
VPN Protocol Comparison
| Protocol | Port | Encryption | Authentication | Use Case |
|---|---|---|---|---|
| IKEv2 / IPsec | UDP 500 / 4500 | AES-256 | Certificates / PSK | Site-to-site & remote access |
| SSL / TLS VPN | TCP 443 | TLS 1.3 | Certificates / MFA | Clientless remote access |
| L2TP / IPsec | UDP 1701 | AES (IPsec) | PSK / Certificates | Legacy remote access |
| WireGuard | UDP 51820 | ChaCha20 | Public keys | Modern high-performance VPN |
| PPTP | TCP 1723 | MPPE (weak) | MS-CHAPv2 | Legacy — avoid in production |
PPTP is considered insecure. IKEv2/IPsec and SSL VPN are the current recommended options.
