NEW QUESTION # 33
Refer to the exhibit.
An SD-WAN zone configuration on the FortiGate GUI is shown. Based on the exhibit, which statement is true?
Answer: D
Explanation:
According to the FortiOS 7.6 Administrator Guide and the specific behavior of the SD-WAN GUI, here is the technical breakdown:
SD-WAN Zone Hierarchy and UI Elements: In the FortiGate GUI, SD-WAN zones that contain member interfaces are displayed with a plus (+) icon next to the checkbox. This icon allows administrators to expand the zone and view the specific physical or logical interfaces assigned to it.
Analysis of the "Underlay" Zone: In the provided exhibit, the virtual-wan-link and overlay zones both feature the plus (+) expansion icon, indicating they have active members. The Underlay zone, however, lacks this icon and displays a red status icon. This is the visual indicator in FortiOS that the zone is currently empty and contains no member interfaces.
Mandatory Zone Membership: In FortiOS 7.x, every SD-WAN member interface must be assigned to a zone.
It is not possible for an interface to be an "SD-WAN member" (as shown in the legend with port2 and port3) without being assigned to a zone. Since port2 and port3 are listed in the legend, they are indeed assigned to one of the other expanded zones (likely virtual-wan-link or overlay), making Option D incorrect.
Default Zone Behavior: While FortiOS 7.6 often creates default zones like virtual-wan-link, underlay, and overlay during certain configuration wizards or by default in newer versions, they are distinct entities. There is no single "default" zone that acts as a global catch-all in the way Option C suggests.
Immutability of System Zones: While certain system-defined zones have restrictions, the primary focus of this specific exhibit is the current membership state, which clearly shows the Underlay zone is empty.
NEW QUESTION # 34
An administrator notices that some users are unable to establish SSL VPN connections, while others can connect without any issues.
What should the administrator check first?
Answer: D
Explanation:
If user traffic is not matching the appropriate firewall policy that permits SSL VPN, users will be unable to establish connections, making this the first aspect to verify.
NEW QUESTION # 35
When configuring a FortiGate in a multi-WAN setup, why would an administrator enable session preservation on an interface? (Choose one answer)
Answer: B
Explanation:
A closely related routing principle from the guide is:
"For each session, FortiGate performs two route lookups... After completing these two lookups, FortiGate writes the routing information to its session table. Subsequent packets are routed according to the session table, not the routing table." Also, the guide notes an HA limitation that helps explain the same design principle for FortiGate-terminated sessions:
"Enabling session pickup allows active sessions to be seamlessly handed picked up by the new primary in the event of an HA failover... Note that there are some limitations to this - for example, any sessions that terminate at the FortiGate itself (e.g. SSL VPN, proxy sessions) cannot be handed off to another FortiGate and must be restarted on the new primary." Technical Deep Dive:
The correct answer is D.
In multi-WAN environments, session preservation is used so that traffic for sessions that are tightly bound to the FortiGate interface they terminate on-most notably SSL VPN and other FortiGate-terminated flows-does not suddenly switch to another egress interface just because the routing table changes. Those sessions are sensitive to interface consistency. If replies start leaving through a different WAN after a route recalculation, the remote peer may see an address/interface mismatch and the session can break.
That means:
A is the opposite of session preservation. Preservation is meant to avoid moving active sessions around.
B is not the purpose of the feature.
C is unrelated.
D correctly describes why an administrator would enable it.
Operationally, this matters most for SSL VPN, management-plane flows, and other sessions that terminate on the FortiGate itself, not just ordinary transit traffic. Transit sessions are generally tracked in the session table and can often survive normal routing behavior more gracefully, but FortiGate-terminated sessions are much more sensitive to WAN/interface changes.
NEW QUESTION # 36
Refer to the exhibits.
An administrator has observed the performance status outputs on an HA cluster for 55 seconds.
Which FortiGate is the primary?
Answer: A
Explanation:
From the HA configuration shown for HQ-NGFW-1:
set memory-based-failover enable
set memory-failover-threshold 70
set memory-failover-monitor-period 50
set memory-failover-sample-rate 10
set memory-failover-flip-timeout 60
set override disable
set priority 200
From the performance status outputs:
HQ-NGFW-1 memory used is 90% (well above the configured threshold of 70%) HQ-NGFW-2 memory used is about 48.7% (well below the threshold) What happens in FortiOS 7.6 with memory-based failover When memory-based failover is enabled, FortiGate monitors memory utilization. If the unit's memory usage stays above the configured memory-failover-threshold for the configured memory-failover-monitor-period, the cluster triggers a failover away from the unit under memory pressure.
Threshold = 70%
HQ-NGFW-1 is at 90%, so it violates the threshold.
Monitor period = 50 seconds.
The administrator observed for 55 seconds, which is longer than 50 seconds, so the condition is met for long enough to trigger failover.
The memory-failover-flip-timeout 60 is used to prevent rapid back-and-forth role changes (flapping) after a failover decision; it does not prevent the initial failover from occurring once the threshold breach persists for the monitor period.
NEW QUESTION # 37
An administrator wanted to configure an IPS sensor to block traffic that triggers the signature set number of times during a specific time period. How can the administrator achieve the objective?
Answer: D
Explanation:
In FortiOS 7.6, if an administrator wants to block traffic only after an IPS signature is triggered a specific number of times within a defined time window, this must be done using IPS filters with rate-based settings.
Why option D is correct
IPS filters allow administrators to match signatures based on attributes such as:
Severity
Protocol
CVE
Signature ID
IPS filters support rate-based actions using:
rate-mode periodical
rate-count
rate-duration
With rate-mode periodical, FortiGate:
Counts how many times a signature is triggered
Within a defined time period
And applies the configured action (for example, block) once the threshold is exceeded This directly matches the requirement:
"block traffic that triggers the signature set number of times during a specific time period." Why the other options are incorrect A). IPS group signatures, set rate-mode 60Group signatures do not provide the required per-period rate-based blocking logic.
B). IPS packet logging optionLogging does not enforce blocking behavior.
C). IPS signatures, rate-mode periodical optionRate-based controls are applied via IPS filters, not directly on individual signature definitions.
