Enablingauto-cachein FortiAnalyzer reports is designed to improve the efficiency and speed of report generation by leveraging cached data. Let’s analyze each option to determine which effects are correct.

Option A - The Generation Time for Reports is Decreased:

When auto-cache is enabled, FortiAnalyzer can use previously cached data instead of reprocessing all log datafrom scratch each time a report is generated. This results in faster report generation times, especially for recurring reports that use similar datasets.

Conclusion:Correct.

Option B - Hard-Cache Data is Automatically Updated When New Logs are Received:

Enabling auto-cache does not immediately update the cache with every new log received. Instead, the cache is updated when reports are generated, based on the existing logs up to that point. Therefore, auto-cache does not constantly refresh with each incoming log, which would be inefficient.

Conclusion:Incorrect.

Option C - FortiAnalyzer Local Cache is Used to Store Generated Reports:

Auto-cache utilizes FortiAnalyzer’s local cache to store data used in reports, reducing the need to retrieve and process logs repeatedly. This cached data can be reused for subsequent report generation, enhancing performance.

Conclusion:Correct.

Option D - The Size of Newly Generated Reports is Optimized to Conserve Disk Space:

Auto-cache does not directly impact the size ofthe report files themselves. It focuses on performance optimization through cached data for faster access, but it does not compress or optimize the storage size of the generated report.

Conclusion:Incorrect.

Conclusion:

Correct Answer:A. The generation time for reports is decreasedandC. FortiAnalyzer local cache is used to store generated reports.

Enabling auto-cache helps reduce report generation time by using locally cached data and optimizes report processing, though it does not impact report size or continuously update with each new log.
