What does the query 'SELECT * FROM $log' return?

The query 'SELECT * FROM $log' is designed to return all records from the specified log type within the Fortinet Fortianalyzer system. In this context, "$log" is a placeholder representing a specific log table that stores entries related to various events such as network traffic, security incidents, or user activities.

When the query is executed, the asterisk (*) serves as a wildcard, indicating that all columns for each record should be included in the output. This means the query fetches every piece of data recorded in the log table, which enables a comprehensive view of all logged activities without any filtering or limitations. This functionality is critical for analysts and network administrators when monitoring systems, reviewing incidents, or conducting audits.

The other options do not accurately describe the outcome of the query:

• Returning only the first row of data would limit the results significantly, which is not the purpose of this SQL command.

• Providing only column headings would not give any substantive information as it lacks the actual log entries that contain the data.

• Claiming that the query is invalid ignores the fact that this is a standard SQL command syntax, making it a valid request for data retrieval.

Thus, the correct answer accurately reflects the purpose and functionality of the SQL query in this context
