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 .

CrowdStrike Parsing Standard (CPS) requires these four tags to classify and normalize events consistently, ensuring compatibility across parsers and enabling accurate correlation and reporting in Next-Gen SIEM.

The correct answer is B. #event.dataset .
CrowdStrike's CPS documentation explicitly lists #event.dataset as one of the CPS-compliant parser tags.
The CPS migration documentation also repeats that CPS-compliant parsers use tags for fields including #ecs.
version , #event.dataset , and #event.kind .
Why the other options are incorrect:
Parser.type and Parser.name are not listed as CPS-compliant tags in the CPS standard.
#event.trigger is also not listed among the CPS-compliant fields/tags.
Therefore, the only CPS-compliant option given is #event.dataset .

The correct answer is A. 9 GB .
CrowdStrike's Falcon LogScale Collector sizing documentation states that memory requirement for memory queues is linearly proportional to the number of sinks plus a constant baseline requirement of 1 GB .
The documentation gives a worked example: 1 GB baseline + queue sizes for each sink .
For this question:
* Number of sinks = 4
* Queue size per sink = 2 GB
* Total sink memory = 4 × 2 GB = 8 GB
* Add baseline memory = 1 GB
So the minimum memory requirement is:
8 GB + 1 GB = 9 GB .
That is why:
* A. 9 GB is correct
* B. 12 GB , C. 10 GB , and D. 8 GB are incorrect because they do not match CrowdStrike's documented sizing formula for memory queues.

CrowdStrike's Fleet Management documentation for Falcon LogScale Collector explains that labels are used to associate metadata with a Fleet Management configuration and with collector instances so they can be tagged, identified, organized, and filtered. The docs specifically describe labels as helping organize collectors by criteria such as environment, region, service, or other custom values. That directly matches option B:
Categorize collectors for group configurations .
Why the other options are incorrect:
Option A is incorrect because labels are not used for authentication or password management.
Option C is incorrect because labels do not perform traffic monitoring; they are metadata for organization and selection.
Option D is incorrect because labels do not assign network settings such as IP addresses.
