FCSS_NST_SE-7.6 Exam Dumps : Fortinet NSE 6 - Network Security 7.6 Support Engineer

The exhibit includes these key debug lines:

start_search_dn-base: ' DC=TAC,DC=ottawa,DC=fortinet,DC=com ' filter:sAMAccountName=jsmith

get_all_dn-Found DN 1:CN=John Smith,CN=Users,DC=TAC,DC=ottawa,DC=fortinet,DC=com

The study guide explains that in regular bind , LDAP authentication has four steps , and that during step 2 , FortiGate searches the LDAP tree to find the user’s DN:

“During the second step, FortiGate does a search query in the LDAP database to find the user’s location—in other words, the user’s DN. If the user is found, the server replies with the user’s DN.”

It also states for the real-time debug of step 2:

“An fnbamd_ldap_build_dn_search_req-base message indicates that FortiGate is performing step two: searching for the user in the LDAP tree. This message includes the base branch (distinguished name setting) and the name of the attribute used to locate the user... If the LDAP server finds the user, the output shows the user’s full DN.”

That directly proves:

D is correct because the debug is showing step 2: Search Request

A is correct because the base DN and found DN are under DC=TAC,DC=ottawa,DC=fortinet,DC=com, which corresponds to the LDAP domain/tree root TAC.ottawa.fortinet.com

Why the other options are wrong:

B is wrong because binding with the user’s credentials is step 3 , not the step shown here. The study guide says: “Step 3 – Bind user credentials” and shows that this happens later with fnbamd_ldap_build_userbind_req / __ldap_build_bind_req-Binding to ' CN=John Smith... '

C is wrong because collecting user group information is step 4 , not the step shown in the exhibit. The study guide says: “The last step is to get the user group information” and shows step 4 with Attr query / memberOf search

The correct answer is A .

The debug output is for an HTTPS request and shows a hostname value. The study guide explains that with SSL certificate inspection, FortiGate extracts the FQDN from either:

“TLS extension server name indication (SNI)”

“SSL certificate common name (CN)”

So the hostname shown in the real-time web-filter debug can be derived from the SNI in the client request or, if needed, from the CN in the server certificate. That makes A correct.

Why the other options are wrong:

B is wrong because the study-guide example for web-filter real-time debug explicitly says: “This slide shows an example of real-time debug output when the URL to categorize isn ' t in the FortiGuard cache.” In these debugs, cat=255 appears before the final lookup result, so this does not indicate a local-cache hit.

C is wrong because ftgd-allow is the action , not the profile name. The debug line shows the action as action=9 (ftgd-allow) while the profile shown is profile= ' default ' . FortiOS web-filter logs also use the profile field separately from the action field

D is wrong because the final category shown is url_cat=52 , not 255. The study guide’s example shows the same pattern: an initial cat=255 in the request line, followed by the resolved result cat=52 url_cat=52

So the verified answer is: A .

The session output includes the flags:

state=redir local may_dirty ...

npu_state=00000000

offload=0/0

The 7.6 study guide explains these flags directly:

local = “Session is to/from local stack”

redir = “Session is being processed by an application layer proxy”

may_dirty = “Session is allowed by a firewall policy”

This makes C correct, because the local flag means the session either originates from FortiGate or terminates on FortiGate . The FortiOS administration guide states the same meaning: “Session is originated from or destined for local stack.”

This also makes A correct. The redir flag means the session is handled by an application-layer proxy . FortiOS documents explain that proxy-based inspection buffers traffic on the FortiGate and inspects it there, and that proxy-based processing is CPU and memory-intensive

Since the session also shows no NPU offload (npu_state=00000000, offload=0/0), this traffic is being handled in software/CPU, not by the NPU.

Why the other options are wrong:

B is wrong because the redir flag proves the session is not passing without inspection; it is being processed by an application-layer proxy

D is wrong because there is no authentication flag in this session. In Fortinet examples of captive portal/authentication-related sessions, the session state includes auth or authed flags. The study guide shows: “Any session for traffic coming from an authenticated user contains the authed flag.” This exhibit does not show auth or authed, so there is no basis to conclude the client was redirected to a captive portal for authentication.
