What methods could be used with Custom Queries for querying logs?

The correct answer is A. Check Point R82 log query language supports complex searches using Boolean operators, wildcards, fields, and ranges. Administrators can enter query text in the SmartConsole Logs & Events query search bar, use predefined queries, modify them, or build custom queries to isolate relevant log records. Option B is wrong because SmartConsole log query syntax is not simply PCRE regular expression syntax. Option C is nonsense; queries are not converted to Base64 for randomization. Option D is wrong because fw monitor and tcpdump are packet capture/troubleshooting tools with different syntax and purpose. Log queries operate against indexed log fields, timestamps, blades, actions, sources, destinations, rules, users, and other event metadata. This capability is essential for incident investigation and operational troubleshooting because it turns large volumes of gateway logs into targeted, searchable evidence.
