The correct answer is B because the analyst is searching for events to either of two destination IP addresses, but the filter uses the wrong Boolean relationship. The FortiSIEM Study Guide explains structured searches with multiple conditions and states that “when you use multiple conditions, you must specify the next logical operator between conditions.” It gives a direct example: when searching for events from two specific devices, the first condition is one IP address, the second condition is another IP address, and “the next logical operator between the two conditions is an OR operator, because the search is for events from condition 1 OR condition 2.” The same logic applies here. A single event cannot usually have Destination IP equal to 10.10.1.1 and Destination IP equal to 192.168.1.1 at the same time. Using AND requires both conditions to be true simultaneously, so no results are returned. The correct operator between the two Destination IP conditions is OR.
