Refer to the exhibit.

The operator is set to " = " , which performs an exact match on the entire raw event log, not a substring search. To find logs that contain the keyword " udp " , the analyst should use the CONTAIN operator instead. This will return all logs where " udp " appears anywhere in the raw log message.

The correct answer is D because the analyst is trying to search for raw logs that contain the keyword udp, but the filter uses the equality operator. The FortiSIEM Study Guide explains keyword searches in terms of Raw Event Log CONTAIN logic. In the keyword phrase search section, the guide states that without quotes, FortiSIEM searches raw event logs by using conditions such as Raw Event Log CONTAIN TCP OR Raw Event Log CONTAIN connection . Another analytics example explains that searching for TCP or UDP events uses the raw event log containing the keyword tcp or udp and that the search returns case-insensitive results for TCP and UDP. This directly eliminates option C. The time range is already set to the last two hours, which is correct for historical raw log searching. The problem is the operator. To find a keyword anywhere inside a raw log message, the analyst should use CONTAIN , not =.
