Refer to the exhibit, which shows a truncated output of a real-time LDAP debug.What two conclusions can you draw from the output? (Choose two.)
Answer(s): B,D
According toFortinet's LDAP authentication workflow as described in the FortiOS Administration Guide and the official LDAP debug log interpretation, each authentication attempt is split into several key steps: Bind Request, Search Request, and then, if successful, a Bind as the found user DN. In the provided debug output, we see "start search_dn-base" with a filter "sAMAccountName=jsmith" and the log line "Going to SEARCH state," confirming that FortiOS is in the second step--the SearchRequest (Option D). Official documentation highlights this exact phrase "SEARCH state" as indicative of Step 2 within the LDAP process ("Bind Search Bind").Additionally, the last line "Found DN 1: CN=John Smith, CN=Users, DC=TAC, DC=ottawa, DC=fortinet, DC=com" verifies that the system has successfully mapped the username to the Distinguished Name (DN) and this user is "John Smith." The authentication will now proceed using this mapped user (Option B). Fortinet's logs record the found DN after a successful search, which is a strong confirmation that the user's credentials can be validated against the found DN.Options A and C are not supported directly by the debug output shown:The server name "Lab" is referenced as part of the request, but not explicitly as the LDAP server's configured name in this output.Step 3 (Bind Request) would follow finding the DN, but the log here demonstrates the Search and DN found--per Fortinet, this precedes the actual Bind/validation step.

Refer to the exhibit, which shows a session entry.Which statement about this session is true?
Answer(s): B
The session output reveals a session with proto=1 (ICMP) and the origin and reply directions show address and NAT translations. Specifically, the hook=post dir=org act=snat shows that source NAT is performed for outgoing packets, where the source 10.1.10.10:40602 is translated to 10.200.5.1:8 (likely ICMP id 8, not a TCP/UDP port). The reply direction, hook=pre dir=reply act=dnat, indicates destination NAT for incoming packets: packets incoming for 10.200.5.1:60430 are destination-NATed to 10.1.10.10:40602. The gateway (gwy) is listed as 10.200.1.254/10.1.0.1, which for outgoing traffic means that return traffic is directed to the gateway (10.200.1.254), per the NAT policy. This is confirmed by the FortiOS Session Table Guide, which explains that the returned ICMP reply will be routed out to this NAT gateway. The session statistics and logical flow (SNAT out, matching DNAT in) reinforce that reply traffic to the initiator traverses via 10.200.1.254.

Which statement about parallel path processing is correct (PPP)?
Answer(s): A
Parallel Path Processing (PPP) in FortiOS refers to the system's ability to evaluate and select among multiple processing paths--often involving dedicated network processors, content processors, or CPU-based workflows--to optimally process packets. The official documentation highlights that the PPP engine dynamically selects which hardware or software path to use for each session based on session characteristics, policy configuration, and traffic type. This dynamic selection results in optimal throughput and resource utilization.The document specifies that PPP assesses several processing paths in parallel, using decision logic to determine whether a session should be offloaded to specialist hardware (like NP6, CP9, etc.) or stay in the CPU path, ensuring that each packet is handled by the most efficient available method under current load and policy. Hardware and software configurations both influence this outcome, but it is the PPP engine's decision-making that defines the optimal path per session.

In IKEv2, which exchange establishes the first CHILD_SA?
According to RFC 7296 (IKEv2) and Fortinet's official documentation, the IKE_SA_INIT exchange is responsible for negotiating cryptographic parameters, performing the initial Diffie-Hellman exchange, and implementing the cookie challenge mechanism for DoS protection. When the responder suspects a DoS attack (such as mass requests by the same source), it includes a cookie in the IKE_SA_INIT response. The initiator must return the cookie in its next request to prove that it truly exists at the IP address it claims, thereby mitigating resource exhaustion attacks.This two-step exchange ensures the responder only allocates resources after successful proof of address, aligning with best security practices. Fortinet documentation confirms that this process occurs strictly in the IKE_SA_INIT phase, not in subsequent IKE_Auth or CHILD_SA exchanges.

Which authentication option can you not configure under config user radius on FortiOS?
Answer(s): D
According to the official Fortinet administration guide for FortiOS 7.6.4 under the section "Configuring a RADIUS server," the supported RADIUS authentication methods you can configure via the CLI with config user radius are:pap chap mschap mschapv2autoThe relevant CLI syntax is set auth-type {auto | ms_chap_v2 | ms_chap | chap | pap} . You can confirm this directly in the configuration table and from real CLI sessions.EAP (Extensible Authentication Protocol) is NOT an authentication option you can directly set under config user radius. EAP methods (such as EAP-TLS, EAP-PEAP, EAP-TTLS) are negotiated between the RADIUS client and server but are not configurable as an explicit auth- type option in FortiOS. EAP authentication is typically used automatically by features like 802.1X, not through the user radius object authentication-type setting, and always requires proper backend workings between supplicant and RADIUS server
