At ValidExamDumps, we consistently monitor updates to the Fortinet NSE7_NST-7.2 exam questions by Fortinet. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Fortinet NSE 7 - Network Security 7.2 Support Engineer exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Fortinet in their Fortinet NSE7_NST-7.2 exam. These outdated questions lead to customers failing their Fortinet NSE 7 - Network Security 7.2 Support Engineer exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Fortinet NSE7_NST-7.2 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Refer to the exhibit, which shows the omitted output of FortiOS kernel slabs.
Which statement is true?
Kernel Slabs Overview:
The slab allocator in the Linux kernel is used for efficient memory management. It groups objects of the same type into caches, which are divided into slabs.
Each slab contains multiple objects and helps to minimize fragmentation and enhance memory allocation efficiency.
Interpreting the Exhibit:
The exhibit shows output related to various kernel slab caches.
The line for ip6_session indicates that there are 1300 kB allocated for this slab, which means the total memory size allocated for IPv6 session objects in the kernel is 1300 kB.

Refer to the exhibits, which show the configuration on FortiGate and partial session information for internet traffic from a user on the internal network.
If the priority on route ID _ were changed from 10 to 0, what would happen to traffic matching that user session?
The exhibits show the configuration of static routes and a session table entry for an active session. The static routes are configured with different priorities:
Route through port1 with a gateway of 10.200.1.254 and priority 5.
Route through port2 with a gateway of 10.200.2.254 and priority 10.
If the priority of the route through port2 is changed from 10 to 0, this route will become more preferred than the route through port1 because lower priority values indicate higher preference. As a result, the traffic for the existing session will switch to using the more preferred route:
The session would remain active in the session table, as FortiGate does not immediately clear sessions upon route changes unless explicitly configured to do so.
The traffic for the session would then start egressing from port2, which now has the higher priority route due to its lower priority value.

Refer to the exhibit, which shows two entries that were generated in the FSSO collector agent logs.
What three conclusions can you draw from these log entries? (Choose three.)
The exhibit shows log entries from the FSSO (Fortinet Single Sign-On) collector agent logs. These logs provide insights into why there might be issues with the collector agent connecting to workstations or the registry.
Remote registry is not running on the workstation: The failure to connect to the workstation registry can occur if the remote registry service on the workstation is not running. This service needs to be active to allow the FSSO collector agent to query the workstation for user login information.
DNS resolution is unable to resolve the workstation name: The logs indicate a failure in connecting to a workstation by name, which can happen if the DNS server is unable to resolve the workstation's name to an IP address. This is a common issue when the DNS settings are incorrect or the workstation name is not properly registered in the DNS.
A firewall is blocking traffic to port 139 and 445: Communication issues to the workstation or registry are often caused by firewall rules blocking essential ports. Ports 139 (NetBIOS) and 445 (SMB) are critical for these operations. Ensure these ports are open on both the workstation and any intermediate firewalls.

Refer to the exhibit, which shows the output of get router info ospf neighbor.
What can you conclude from the command output?
Understanding OSPF Roles:
In OSPF (Open Shortest Path First), routers can have different roles: Designated Router (DR), Backup Designated Router (BDR), and DROther. These roles help manage and optimize the OSPF network traffic.
DR and BDR are elected to minimize the number of adjacencies and reduce the amount of routing information exchange.
DROther routers are neither DR nor BDR but can still participate in the OSPF network by maintaining adjacencies with DR and BDR.
Analyzing the Exhibit:
The exhibit shows the OSPF neighbor states for the local FortiGate.
Neighbor ID 0.0.0.1 is in the state Full/DR (Designated Router).
Neighbor ID 0.0.0.3 is in the state Full/DROther (DROther).
Neighbor ID 0.0.0.10 has no specific designation, implying it is neither DR nor BDR.
Conclusion:
Since the local FortiGate shows neighbors in Full/DR and Full/DROther states and itself does not have a state of DROther, it can be concluded that the local FortiGate is not a DROther.

Refer to the exhibit, which shows a truncated output of a real-time RADIUS debug.
Which two statements are true? (Choose two.)
RADIUS Server IP Address:
The debug output shows that the RADIUS request was sent to the server at IP=172.25.188.164. This indicates that the RADIUS server being queried for authentication is indeed located at this IP address.
Authentication Result:
The debug output includes a line indicating the result for the RADIUS server: Result for radius svr 'RadiusServer' 172.25.188.164(0) is 0. A result code of 0 typically signifies that the authentication attempt was unsuccessful.
Authentication Scheme:
The debug output does not indicate that the authentication scheme used was pop3; it mentions using CHAP (Challenge Handshake Authentication Protocol).
Two-factor Authentication:
There is no indication in the debug output that two-factor authentication was required for this session.
