Firewall Policies and Authentication and Deployment and System Configuration typically account for a larger share of exam items because they form the foundation of any Fortinet deployment. However, all five topics are important; expect balanced coverage across Routing, VPN, and Content Inspection as well. Review the official exam blueprint to confirm current weighting.
VPN tunnels terminate on the firewall, and firewall policies control traffic flowing through those tunnels. In practice, you must create policies that permit encrypted traffic to and from VPN endpoints, apply content inspection to VPN traffic, and route VPN packets correctly. Understanding this relationship is critical for secure remote access and site-to-site connectivity scenarios.
At least three to six months of practical experience configuring and troubleshooting FortiOS firewalls is recommended. If you have limited hands-on time, prioritize labs in Deployment and System Configuration, Firewall Policies and Authentication, and basic Routing. Fortinet provides free trial instances and sandbox environments where you can practice safely.
Candidates often confuse policy order and matching logic, miss subtle differences between authentication methods, or overlook routing metrics and priorities. Another frequent error is misunderstanding how Content Inspection profiles interact with policies. Read scenario questions carefully, pay attention to specific FortiOS version details, and double-check configuration syntax before submitting answers.
Shift from learning new material to review and practice. Complete one full-length timed mock exam, review all incorrect answers, and focus on your weakest topics. In the last two days, do light review of key definitions and workflows rather than heavy study. Get adequate sleep and avoid cramming, which increases test-day anxiety and reduces performance.

Based on the current HA status, an administrator updates the override and priority parameters on HQ-NGFW-1 and HQ-NGFW-2 as shown in the exhibits.
What would be the expected outcome in the HA cluster?
From the current HA status, HQ-NGFW-1 is the primary and HQ-NGFW-2 is the secondary.
The administrator then changes these HA parameters:
HQ-NGFW-1: set override disable, set priority 90
HQ-NGFW-2: set override enable, set priority 110
In FGCP (A-P mode), the override (preemption) feature controls whether a higher-priority unit is allowed to take over the primary role.
When override is enabled, the cluster will prefer (and can re-elect) the unit with the highest device priority to become primary (preempting a lower-priority primary when conditions trigger re-election behavior as defined by FGCP).
Here, HQ-NGFW-2 has:
override enabled
higher priority (110) than HQ-NGFW-1 (90)
Therefore, the expected result is that HQ-NGFW-2 becomes the primary.
Why the other options are incorrect:
B is incorrect because it claims HQ-NGFW-2 has lower priority (it is higher: 110 > 90).
C is incorrect because a mismatch in the override setting is not what causes the ''configuration out of sync'' condition shown in get system ha status (that is about synchronized configuration databases, not a requirement that override values must match to remain in-sync).
D is incorrect because HA settings like override/priority are not synchronized in the way regular configuration objects are; they are device-level HA parameters.
Which two statements are correct when FortiGate enters conserve mode? (Choose two answers)
According to the FortiOS 7.6 Study Guide and technical documentation, conserve mode is a protective state triggered when memory utilization reaches the Extreme Threshold (typically 95% by default). When this occurs, the FortiGate implements several measures to prioritize system stability over new functionality. One of the primary restrictions is that the FortiGate refuses to accept configuration changes (Statement B). This prevents the system from initiating new processes or allocating additional memory that could lead to a total system crash.
Regarding traffic handling, the behavior is determined by specific 'fail-open' settings. For the IPS engine, if the fail-open global setting is enabled, the FortiGate continues to transmit packets without IPS inspection (Statement D). This ensures that network connectivity is maintained even when the system lacks the memory resources to perform deep packet inspection. In contrast, Statement A is incorrect because the system may skip non-essential actions to save memory. Statement C is incorrect because conserve mode is designed to avoid a system halt; the device remains operational and will automatically exit conserve mode once memory usage drops below the Release Threshold (typically 82%).

Why is the Antivirus scan switch grayed out when you are creating a new antivirus profile for FTP?
In FortiOS 7.6, the Antivirus scan master switch in an antivirus profile becomes available only after at least one supported protocol is enabled for inspection.
What the exhibit shows
A new antivirus profile named FTP_AV_Profile
Feature set: Flow-based
Antivirus scan switch is grayed out
All Inspected Protocols (HTTP, SMTP, POP3, IMAP, FTP, CIFS) are currently disabled
Why the Antivirus scan switch is grayed out
In FortiOS antivirus profiles:
The Antivirus scan toggle is a dependent control
It cannot be enabled unless at least one inspected protocol is selected
This prevents enabling AV scanning when there is no traffic type to scan
This behavior is documented in the FortiOS 7.6 Antivirus Profile configuration section.
Once you enable a protocol (for example, FTP), the Antivirus scan switch becomes active and configurable.
Why option B is correct
B . None of the inspected protocols are active in this profile.
All protocol toggles are OFF
Therefore, FortiGate disables (grays out) the Antivirus scan option
This is expected and correct behavior
Why the other options are incorrect
A . Antivirus scan is disabled under Feature visibilityIncorrect. Feature Visibility controls whether Antivirus appears in the GUI, not whether the scan switch is enabled inside a profile.
C . Feature set must be Proxy-basedIncorrect. Antivirus scanning is supported in both flow-based and proxy-based modes.
D . Less than 2 GB RAM does not support Antivirus scanIncorrect. Memory size affects performance and offloading, not basic AV scan availability.
Refer to the exhibit.
Which two ways can you view the log messages shown in the exhibit? (Choose two.)
The exhibit shows a FortiGate UTM application control log with fields such as:
type='utm'
subtype='app-ctrl'
action='block'
policyid=1
appid=30220
appcat='Video/Audio'
service='HTTP'
apprisk='elevated'
This is a forward traffic security log, generated by Application Control applied to a firewall policy.
Why the correct answers are C and D
C . By filtering by policy universally unique identifier (UUID) and application name in the log entry
Correct.
FortiOS logs can be viewed and filtered in:
Log & Report Forward Traffic
Administrators can filter logs using fields such as:
Policy ID / Policy UUID
Application name (app)
Application ID (appid)
The log entry clearly includes application-related fields, making filtering by policy and application a valid and documented way to view these logs.
D . In the Forward Traffic section
Correct.
The log is a UTM Application Control log for traffic passing through a firewall policy.
Such logs are displayed under:
Log & Report Forward Traffic
This is the standard and correct location to view application control, web filter, IPS, and other security profile logs related to user traffic.
Why the other options are incorrect
A . By right clicking the implicit deny policy
Incorrect.
Implicit deny policies do not generate UTM forward traffic logs like the one shown.
Application control logs are generated only by explicit firewall policies with security profiles enabled.
B . Using the FortiGate CLI command diagnose log test
Incorrect.
diagnose log test is used to test log connectivity and log settings, not to view historical log entries.
It does not display traffic or UTM logs.
Refer to the exhibit.
Based on the routing table shown in the exhibit, which two statements are true? (Choose two.)
