CrowdStrike CCSE-204 Dumps

The correct answer is D. @event_parsed .

CrowdStrike LogScale’s parser error documentation explicitly states that @event_parsed indicates whether the event has been successfully parsed during ingest . The same documentation says it is set to false when there was a parsing error. That exactly matches the question.

Why the other options are incorrect:

@ingesttimestamp represents the time the platform ingested the event, not whether parsing succeeded. @rawstring contains the original raw event data. @error_msg can contain error details, but it is not the primary field that directly indicates parse success or failure. The field CrowdStrike documents for parsing status is @event_parsed .

The correct answer is B . The best tuning step is to exclude known trusted IP addresses so the rule still detects suspicious sequences while removing known-benign sources of repeated authentication activity. CrowdStrike has publicly documented this tuning principle in detection content guidance, noting that to avoid false positives, organizations may want to exclude certain IP ranges, ASNs, or ISPs from a rule when those sources are expected or trusted. That directly supports the idea that adding a trusted-IP exclusion reduces noise while preserving the core detection logic.

Why the other options are incorrect:

A would usually increase noise because a larger time window captures more benign failed logins. C would also increase false positives because lowering the failed-attempt threshold makes the rule easier to trigger. D weakens the original attack logic by removing the “failed logins followed by success” sequence that makes the rule more specific and meaningful. Keeping the core sequence intact while adding exclusions for known benign sources is the most precise tuning approach.

In the Next-Gen SIEM Connector Dashboard (specifically within the CrowdStrike Falcon ecosystem), the maximum retention period for which you can query third-party data ingestion metrics is 90 days .

Why 90 Days?

While the actual log data (telemetry) in a Next-Gen SIEM can often be retained for a year or longer depending on the subscription (e.g., 365 days), the health and ingestion metrics —which include data such as volume throughput, connector status, and ingestion rates—are typically stored for a shorter duration. This 90-day window is designed to provide enough historical context for:

Troubleshooting: Identifying when a specific connector started failing.

Trend Analysis: Monitoring changes in data volume over a fiscal quarter.

Capacity Planning: Reviewing average ingestion rates to ensure they stay within licensed limits.
