What is the benefit to use Log Indexing?

The correct answer is A. The benefit of Log Indexing is faster log searching and querying. In Check Point R82, logs can be indexed so SmartConsole Logs & Events and SmartView can return query results more efficiently, especially in environments generating large volumes of Firewall, VPN, HTTPS Inspection, Application Control, URL Filtering, and Threat Prevention logs. Option B is wrong because indexing does not primarily reduce disk usage; it can actually require additional storage because index data must be maintained. Option C describes investigation value that may come from correlated logs and event analysis, but it is not the direct benefit of indexing itself. Option D is incorrect because Log Indexing is not a duplicate-removal mechanism. The operational value is speed: indexed logs let administrators investigate faster by searching fields, actions, sources, destinations, users, blades, and time ranges more efficiently.
