Question #1
In a Secure Private Access (SPA) with SD-WAN deployment, which routing protocol does FortiSASE use to exchange routes with the hub FortiGate over the IPsec overlay?
Correct answer: D
Explanation
FortiSASE peers with the hub FortiGate using BGP across the IPsec tunnel, so the hub can advertise internal prefixes to the security point of presence (POP) and learn the FortiSASE endpoint subnets. Interior protocols such as OSPF are not used for this overlay peering.

Question #2
In a ZTNA deployment, FortiClient connects to the access proxy to reach a protected application. What does the access proxy use to identify the endpoint device?
Correct answer: D
Explanation
FortiClient EMS issues a device certificate to each registered endpoint, and the ZTNA access proxy uses it to identify the device and match ZTNA tags. A SAML assertion or one-time password authenticates the user, not the device, and ZTNA does not rely on a pre-shared key.

Question #3
Refer to the exhibit. Remote users connected through FortiSASE can reach servers in 10.10.0.0/16 at headquarters, but they cannot reach servers in 172.16.40.0/24, which is also behind the hub FortiGate. The IPsec tunnel is up and the BGP neighbor is established. Exhibit: Hub-FGT # show router bgp config router bgp set as 65100 set router-id 10.10.10.1 config neighbor edit "10.10.254.1" set remote-as 65100 set update-source "Lo-HUB" next end config network edit 1 set prefix 10.10.0.0 255.255.0.0 next end end What is the cause of the problem?
Correct answer: B
Explanation
Only the 10.10.0.0/16 prefix is listed under the BGP network statements, so FortiSASE never learns a route to 172.16.40.0/24. Because the tunnel is up, the BGP session is established, and users already reach 10.10.0.0/16, the phase 1 settings and AS numbers are not at fault.

Question #4
A FortiSASE administrator must see which user devices have registered, assign an endpoint profile to them and tag them for ZTNA posture checks. Which FortiSASE component provides these functions?
Correct answer: D
Explanation
FortiSASE includes a hosted FortiClient EMS that manages endpoint registration, endpoint profiles and ZTNA tagging. FortiAnalyzer Cloud handles logs and reports, the security PoP inspects traffic, and a SAML IdP only authenticates users.

Question #5
Refer to the exhibit. A FortiSASE administrator reviews DNS logs for a single endpoint. Exhibit: date=2026-10-12 time=14:03:11 type="utm" subtype="dns" user="rpatel" srcip=10.253.4.22 qname="a8x2kd0vq.example-cdn.net" action="block" catdesc="Botnet" date=2026-10-12 time=14:03:16 type="utm" subtype="dns" user="rpatel" srcip=10.253.4.22 qname="q1zw7m4pe.example-cdn.net" action="block" catdesc="Botnet" date=2026-10-12 time=14:03:21 type="utm" subtype="dns" user="rpatel" srcip=10.253.4.22 qname="v6t9jr3hc.example-cdn.net" action="block" catdesc="Botnet" The pattern continues every five seconds for several minutes. What is the most likely explanation?
Correct answer: A
Explanation
Rapid, regular queries to random-looking subdomains that all fall into the Botnet category are typical of a domain generation algorithm used by malware. The blocks show the DNS filter working as intended, and the endpoint should be investigated and isolated. An outage would not produce category-based block actions.

Question #6
A company has a FortiGate 600F at headquarters that acts as the IPsec hub for Secure Private Access (SPA). Remote users connected to FortiSASE must reach the 10.10.0.0/16 subnet at headquarters. The public IP addresses of the FortiSASE security points of presence (POPs) are not known to the hub in advance. Which configuration on the hub FortiGate allows it to accept the FortiSASE tunnels and learn their routes?
Correct answer: C
Explanation
Because the FortiSASE POP addresses are not known to the hub, the hub must use a dialup (dynamic) IPsec VPN, and a BGP neighbor range lets it peer with the spokes and exchange routes. A static site-to-site tunnel needs a fixed remote gateway. SSL VPN and GRE are not how FortiSASE connects to a hub in an SPA deployment.

Question #7
A company wants FortiSASE to scan HTTPS downloads for malware. Privacy rules require that traffic to banking websites is not decrypted. Which security profile design meets both requirements?
Correct answer: B
Explanation
Antivirus can only scan encrypted downloads when deep inspection is used, and the exemption list keeps selected categories from being decrypted. Certificate inspection cannot see file content. A web filter allow list changes the filter action but does not exempt the traffic from decryption.

Question #8
A FortiSASE administrator must prevent remote users from uploading files that contain credit card numbers to personal cloud storage sites over HTTPS. The security profile group applied to the internet access policy currently uses the certificate-inspection SSL profile. What should the administrator configure?
Correct answer: C
Explanation
DLP must read the payload of the upload, and encrypted HTTPS content is only visible when the SSL profile performs deep inspection. Certificate inspection sees the server certificate and SNI only, so a DLP sensor would never match card numbers. A file filter matches file types, not content, and blocking the storage category would stop all uploads rather than only the sensitive ones.

Question #9
Remote users connect to FortiSASE with FortiClient and access a SaaS CRM application. The SaaS provider accepts logins only from a fixed list of source IP addresses. The source addresses that FortiSASE uses for internet-bound traffic at its security points of presence (PoPs) are shared with other customers and can change. Which FortiSASE component must the administrator add to meet the requirement?
Correct answer: B
Explanation
Dedicated public IP addresses give the tenant a stable source address at its security PoPs, which the SaaS provider can allow list. A split tunneling exclusion sends the traffic out from each user's own network, so the source address varies by location. ZTNA gateways and tags control access to private applications or endpoint posture, and neither changes the source NAT address of internet traffic.

Question #10
Refer to the exhibit. Exhibit: Internet access policy Name: Internet-Access-Users Source: All endpoint users Destination: All Internet Traffic Action: Accept Security Profile Group: Standard-Inspection Log Traffic: Security Events A FortiSASE administrator searches the forward traffic logs for allowed sessions from user c.rivera to a news website. No entries appear, although blocked web filter events for other users are listed. What should the administrator change?
Correct answer: A
Explanation
With Log Traffic set to Security Events, the policy only writes logs for sessions that trigger a security profile, so plain allowed sessions are not recorded. Setting Log Traffic to All Sessions records every session that matches the policy. Longer retention and deep inspection do not cause allowed sessions to be logged.
