NSE7 Advanced VPN and Zero Trust Practice Question
An administrator is troubleshooting a ZTNA application access issue. Users can authenticate but cannot reach the internal application via the ZTNA proxy. The FortiGate's ZTNA rule uses a tag requiring 'OS Type = Windows' and 'Antivirus = running'. The device meets both conditions. Which THREE possible reasons could cause the access failure?

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 proxy's destination is pointing to the wrong internal IP or port.
The device meets the ZTNA tag conditions (OS Type=Windows, Antivirus=running), so D (tag assignment) and E (FortiClient installation) are not the cause. Access failure can occur if: A) the ZTNA proxy's destination points to the wrong internal IP or port, B) the firewall policy for ZTNA traffic is not configured or is misordered, or C) the FortiGate's SSL certificate for the ZTNA proxy is not trusted by the client. These are the three most common reasons when posture is satisfied.
