Three of the 84 questions in this pack

Question 1

The FortiGate device HQ-NGFW-1 with the IP address 10.0.13.254 sends logs to the FortiAnalyzer device with the IP address 10.0.13.125. The administrator wants to verify that reliable logging is enabled on HQ-NGFW-1.

Which exhibit helps with the verification?

✅Correct Answer: D, FortiGate management interface showing All Logging Devices (1) with device HQ-NGFW-1 at IP 10.0.13.254, FortGate-VM64-KVM

platform, firmware 7.6.0.build3401, serial FGVM02TM24013342, status Up, with a green indicator for Real Time logging mode visible, disk quota usage showing 50 GB

The two FortiAnalyzer Device Manager screens are identical except for one detail: in D the Logging Mode cell for HQ-NGFW-1 at 10.0.13.254 shows Real Time with a padlock. FortiAnalyzer displays that padlock when the log stream arrives over a secured OFTP session, which FortiOS builds only on top of the reliable TCP transport, so it confirms that reliable logging is active on the FortiGate. The administrator can verify the setting from the FortiAnalyzer side without touching the FortiGate CLI, which is exactly what the question asks the exhibit to do.

Question 2

A network administrator has enabled full SSL inspection and web filtering on FortiGate.

When visiting any HTTPS websites, the browser reports certificate warning errors.

When visiting HTTP websites, the browser does not report errors.

What is the reason for the certificate warning errors?

  1. The matching firewall policy is set to proxy inspection mode.
  2. The option invalid SSL certificates is set to allow on the SSL/SSH inspection profile.
  3. The certificate used by FortiGate for SSL inspection does not contain the required certificate extensions.
  4. The browser does not trust the certificate used by FortiGate for SSL inspection. ✅Correct Answer: D, The browser does not trust the certificate used by FortiGate for SSL inspection. When FortiGate performs full SSL inspection, it re-signs the server certificate with its own CA certificate to decrypt and inspect HTTPS traffic. The browser reports certificate warning errors because that CA is not in its trusted store, so the presented certificate is not issued by a trusted Certificate Authority. Installing the FortiGate CA certificate on the clients removes the warnings. HTTP sites show no errors because that traffic is not encrypted and involves no certificate validation.

Answer and explanation for question 2

Question 3

Refer to the exhibit, which shows a firewall policy to enable active authentication.

When attempting to access an external website using an active authentication method, the user is not presented with a login prompt.

What is the most likely reason for this situation?

Exhibit for question 3

  1. The Service DNS is required in the firewall policy.
  2. The Remote-users group is not added to the Destination.
  3. The Remote-users group must be set up correctly in the FSSO configuration.
  4. No matching user account exists for this user.
Show answer and explanation

Correct answer: A. The Service DNS is required in the firewall policy.

The exhibit shows a port4 to port2 policy whose Source is HQ_SUBNET together with the Remote-users group, Destination all, and Service limited to ALL_ICMP, HTTPS and HTTP. Because a user group is referenced in Source, FortiGate will challenge matching HTTP or HTTPS traffic with the captive portal. The problem is that DNS is not in the Service list, so the workstation cannot resolve the external site name. Without a resolved address the browser never generates the HTTP or HTTPS request, FortiGate never sees a session that needs authentication, and no login prompt is displayed. Adding the DNS service, or a separate policy allowing DNS, restores the redirect.

Why the other options are wrong

  • B. User groups are referenced in the Source column, which is exactly where Remote- users already appears in the exhibit; Destination holds addresses and is correctly set to all.
  • C. FSSO is passive authentication and nothing in the exhibit points to an FSSO group; an active authentication policy uses a local or remote user group instead.
  • D. If the account were simply missing, the captive portal page would still be presented and the credentials would then be rejected, so the absence of any prompt is not explained.

What makes the NSE 4 hard

If searching for FCP_FGT_AD-7.6, it is the same exam. Fortinet retired the FCF, FCA, FCP, FCSS and FCX names on 15 July 2026 and put the program back on visible NSE 1 to 8 levels. The FortiGate Administrator exam is now NSE 4, FortiOS 7.6 Administrator, registered as NSE4_FGT_AD-7.6, with the same content and blueprint under a new label.

It pays to watch the version, not just the name. Fortinet has NSE 4, FortiOS 8.0 Administrator scheduled for release in mid-September 2026, and Fortinet’s stated practice is that the previous version stays bookable for roughly four months after a new one lands, so anyone studying 7.6 should book it rather than drift into the changeover.

NSE 4 is the entry point to the whole ladder: the FortiManager, FortiAnalyzer and Enterprise Firewall credentials all sit above it, so everything downstream stalls until this one is done.

The exam is not a definition quiz. It leans on configuration extracts, CLI output and troubleshooting scenarios, and content inspection alone is up to 30% of it. This pack has 84 practice questions across all five domains, with every answer explained.
