Refer to the exhibits.


Examine the FortiGate configuration, FortiAnalyzer logs, and FortiGate widget shown in the exhibits.
Security Fabhc quarantine automation has been configured to isolate compromised devices automatically.
FortiAnalyzer has been added to the Security Fabric, and an automation stitch has been configured to quarantine compromised devices.
To test the setup, a device with the IP address 10.0.2.1 that is connected through a managed FortiSwitch attempts to access a malicious website. The logs on FortiAnalyzer confirm that the event was recorded, but the device does not appear in the FortiGate quarantine widget.
Which two reasons could explain why FortiGate is not quarantining the device? (Choose two.)
Antwort: A,B
Begr¨¹ndung:
In this scenario:
* FortiGate + FortiAnalyzer are part of theSecurity Fabric
* AnAutomation Stitchis configured:
* Trigger:Compromised Host - High(IOC from FortiAnalyzer)
* Actionuarantine on FortiSwitch + FortiAP
A test device10.0.2.1visits a malicious website.
FortiAnalyzer logs show the event, butFortiGate does NOT quarantine the device.
This means theautomation did not receive an IOC trigger, OR theFabric did not classify it as a compromise.
Let's evaluate each answer option.
#C. The malicious website is not recognized as an indicator of compromise (IOC) by FortiAnalyzer.
#Correct.
For FortiGate to quarantine a device:
* FortiAnalyzer must classify the event as aCompromised Host # High / Medium / Critical
* FortiAnalyzer must generate anIOC event
* FortiGate must receive that IOC through the Fabric
Even though the FAZ log shows:
* Action = blocked
* Category = Malicious Websites
# That doesNOTautomatically mean an IOC was generated.
A blocked website event isnot always an IOCunless:
* It is included in theIOC database
* FAZ'sAnalytics / UTM / IOCengine marks it as a compromise
Thus, if FAZ only logs a "Malicious Website" event butdoes not classify it as an IOC,

73. Frage
Refer to the exhibit.

Which shows the WTP profile configuration.
The AP profile is assigned to two FAP-231F APs that are installed in an open plan area.
The first AP has 32 clients associated with the 5 GHz radios and 22 clients associated with the 2.4 GHz radio.
The second AP has 12 clients associated with the 5 GHz radios and 20 clients associated with the 2.4 GHz radio.
A dual-band-capable client enters the area near the first AP and the first AP measures the new client at - 3 3 dBm signal strength. The second AP measures the new client at -43 dBm signal strength.
If the new client attempts to conned to the student 01 wireless network, which AP radio will the client be associated with?
Antwort: A
Begr¨¹ndung:
From theWTP profile:
set handoff-rssi 30
set handoff-sta-thresh 30
config radio-1
set band 802.11n-2G
set vaps "Student01"
config radio-2
set band 802.11ac-5G
set darrp enable
set arrp-profile "arrp-default"
set vaps "Student01"
Key points:
* Same SSID (Student01)is broadcast onboth APsand onboth bands(2.4 and 5 GHz).
* handoff-sta-thresh 30 enablesclient load-balancingbetween APs:
* When an AP radio hasmore than 30 associated clients, it starts rejecting new associations so that clients connect to a neighboring AP instead (as long as RSSI is still acceptable).
* Current client counts:
* AP1:32 clients on 5 GHz, 22 on 2.4 GHz
* AP2:12 clients on 5 GHz, 20 on 2.4 GHz
So on 5 GHz:
* AP1's 5-GHz radioexceedsthe 30-client threshold (32 > 30) # it will try topush new clients away.
* AP2's 5-GHz radio iswell belowthe threshold (12 clients) and will happily accept new clients.
The new dual-band client is seen at:
* -33 dBmby AP1
* -43 dBmby AP2
Even though AP1 has the stronger signal, its 5-GHz radio is already overloaded according to the configured threshold, so AP1 will refuse association attempts from that client. The client will then associate toAP2's 5- GHz radio, which:
* Hasfewer clients(better airtime per device), and
* Still has an acceptable signal (-43 dBm is easily usable on 5 GHz).
That matches optionCexactly.
Other options are incorrect because they ignore the configuredclient-load-balancing thresholdsand assume association based purely on RSSI or prefer 2.4 GHz, which is not what this profile is tuned to do.

74. Frage
Refer to the exhibit.



Review the exhibits to analyze the network topology, SSID settings, and firewall policies.
FortiGate is configured to use an external captive portal for authentication to grant access to a wireless network. During testing, it was found that users attempting to connect to the SSID cannot access the captive portal login page.
What configuration change should be made to resolve this issue to allow users to access the captive portal?
Antwort: D
Begr¨¹ndung:
From the exhibits:
* SSID "Guest"
* Security mode:Open
* Captive Portal: Enabled, portal typeAuthentication # External
* External portal URL: https://fac.trainingad.training.lab/guest (FortiAuthenticator)
* Exempt destinations/services:FortiAuthenticator and WindowsAD
* Firewall policy
* From theGuest interface/zonetoport1 (Internet)
* Source user group:guest.portal(authenticated users)
The flow for anexternal captive portalis:
* Client associates to theopen Guest SSID.
* Client makes an HTTP(S) request.
* FortiGate intercepts and redirects the client to theexternal portal.
* Client must be able toreach FortiAuthenticator's IP(and AD if the portal needs it)before authentication.
In this setup:
* Theexempt destinationsetting tells the captive portal logicnot to require authenticationfor traffic going to FortiAuthenticator and WindowsAD.
* However, there still must be a firewall policy that allows traffic from the Guest SSID subnet to those exempt destinations.
The existing firewall policy uses theguest.portal user groupas a source condition, which only matchesafter successful portal authentication. Before login, the client has no user identity, so:
* Traffic from the unauthenticated Guest client # FortiAuthenticator isnot matchedby that policy.
* It hits theimplicit deny, so the browser never reaches the login page.
To fix this, the administrator must:
* Create or modify a firewall policy thatallows traffic from the Guest SSID subnet/interface to FortiAuthenticator and WindowsAD without requiring user authentication.
That is exactly what optionDdescribes.
Why the others are wrong:
* A. Change SSID security mode to WPA2-Enterprise- External captive portals are normally used with openSSIDs; WPA2-Enterprise uses 802.1X, not captive portal.
* B. Disable HTTPS redirection- Redirection is required so users are sent to the portal; disabling it doesn't solve reachability.
* C. Exclude FortiAuthenticator and Windows AD from filtering- They're already listed asexempt destinationsin the SSID configuration; the missing piece is thefirewall policy, not the exemption.

75. Frage
Which data sources does FortiAIOps use for correlation and anomaly detection?
(Choose three)
Response:
Antwort: A,B,D

76. Frage
How can FortiAIOps help optimize network performance in an SD-Branch deployment with FortiGate, FortiSwitch, and FortiAP?
Antwort: A
Begr¨¹ndung:
In an SD-Branch deployment (FortiGate + FortiSwitch + FortiAP),FortiAIOps:
* Collects telemetry and logs from Fabric devices
* Usesmachine-learning / AI analyticsto:
* Spot anomalies (latency, packet loss, RF issues, misconfigurations)
* Highlight root causes
* Proposeoptimization recommendations(e.g., channel changes, power tuning, config fixes) It doesnot:
* Automatically disable devices (Afalse)
* Replace SD-WAN config or all routing (Cfalse)
* Fixallissues with zero human input (Dis marketing fantasy, not reality)
