Refer to the exhibits.

The correct answer is B . In the trigger exhibit, the Filter Match setting is configured as Any 1 Filters , meaning the security trigger is satisfied when any one of the defined filters matches within the configured time window. The contractor triggers two of the defined filters, so two separate security events are generated because FortiNAC-F creates a security event whenever a security filter matches. The study guide confirms that each matched filter generates a security event, and when a trigger contains multiple filters, multiple matched filters can be associated with the resulting alarm.

The security rule exhibit also shows User/Host Profile: Match Contractors . Because the triggering user is a contractor, the user/host profile condition is satisfied. Once the trigger is satisfied and the user/host profile matches, FortiNAC-F generates a security alarm . The fact that Action is set to None does not stop the alarm from being generated; it only means no automated or manual response action is executed from that rule. Option A is wrong because the contractor profile matches, so an alarm is generated. Option C is wrong because only two filters were triggered, not three. Option D is wrong because two filters matched, so two events are generated, not one.
