The correct answer is C. Number of concurrent requests a sink is using .

CrowdStrike’s Falcon LogScale Collector sizing guidance states that in high throughput scenarios where the ingestion endpoint becomes a bottleneck, it can be beneficial to increase the number of concurrent requests a sink is using through the workers setting. The docs explicitly say this helps when the number of parallel requests is limiting throughput.

The same document also explains why D is wrong: increasing the memory queue size does not increase sink throughput. The queue exists to keep data available for the sink; if throughput is lower than the incoming data rate, the queue will eventually fill up anyway.

So:

C is correct because more sink workers can improve performance in high-volume conditions.

D is incorrect because queue size does not fix the throughput bottleneck.

A and B are not the documented tuning setting for this issue in the collector guidance.

==========

The least-privilege role for users who only need to view dashboards, searches, and investigation data without making changes is NG SIEM Analyst – Read Only . This role is designed for visibility without content modification or administrative access. The other roles provide broader operational or management permissions.

The correct answer is C. parseCsv() .

CrowdStrike LogScale documentation for parseCsv() states that the function supports a configurable delimiter parameter, and it is used to split a field into named columns. Because this log is space-delimited and the values are always in the same order, parseCsv() is the appropriate parser function by specifying a space as the delimiter and naming the columns in order.

Why the other options are incorrect:

A. parseCEF() is for CEF-formatted logs, which this event is not.

B. parseJson() is for JSON, and this event is plain text.

D. parseFixedWidth() is meant for logs where each field occupies a strict character width. CrowdStrike’s docs describe it as valuable when data must maintain strict positional formatting and defined field lengths. This question only guarantees field order , not fixed character widths, so parseFixedWidth() is not the best match.

When a third-party field does not map to ECS, CPS guidance is to preserve it using the Vendor. prefix. This keeps the field searchable and retains source-specific context while maintaining normalization standards. Removing the field or forcing it into an unrelated ECS field would reduce data quality and clarity.

The correct answer is C. logscale-collector .

CrowdStrike’s Falcon LogScale Collector installation documentation states that the service name varies by installation method. It explicitly says that for Full Installation the service is called logscale-collector , while Custom Installation uses humio-log-collector . Since the question specifically refers to deployment using the Fleet Management interface commands , that aligns with the Full Installation workflow, so the correct service name is logscale-collector .

==========

The correct answer is C .

CrowdStrike’s CPS documentation explicitly lists the CPS-compliant parser tags, and the relevant four event parser tags in that list are #event.dataset , #event.kind , #event.module , and #event.outcome . That exactly matches option C.

Why the other options are incorrect:

event.category is an important event categorization field in CPS, but it is not one of the four parser tags listed in the CPS tag set that this question is asking about. The documented parser tag list includes event.dataset , event.kind , event.module , and event.outcome .

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 B. NG SIEM Security Lead . Parser creation and management requires elevated SIEM content and configuration capabilities that go beyond standard analyst activity, but it does not require the full breadth of platform-wide administrative control. NG SIEM Security Lead is the default role that best fits parser management while still maintaining least privilege compared with NG SIEM Administrator . NG SIEM Analyst and NG SIEM Analyst – Read Only do not provide the content-management level access needed for parser administration. CrowdStrike’s SIEM role separation supports using the Security Lead role for advanced SIEM content configuration tasks.

==========

The correct answer is C. Select “Manage Internal Logging” from the menu .

CrowdStrike LogScale Collector documentation for Fleet Management explicitly describes the steps to enable internal logging from the Fleet view. It says to go to Data Ingest > Fleet Overview , click the ellipsis next to the specific collector instance, and then click Manage Internal Logging . From there, you can enable logging and choose where to send it.

Why the other options are incorrect:

A is incorrect because reinstalling the collector is not required. B is incorrect because the question specifically asks how to do it from the Fleet view , and the documented UI action is through the menu in Fleet Management, not by manually editing the local config. D is incorrect because the documentation does not describe enabling internal logging by restarting the service with a special flag.

==========

The correct answer is A. The parser was incorrect .

CrowdStrike LogScale documentation explains that when data is ingested without an appropriate parser , the event still arrives in LogScale, but it is not automatically parsed into fields . In that case, the event remains as raw text in @rawstring, while the expected extracted fields stay empty. That matches the exact symptom described in the question.

Why the other options are incorrect:

B is incorrect because if the ingestion token were invalid, the data generally would not be ingested successfully in the first place. C is incorrect because an overloaded sink may delay or buffer delivery, but it does not explain why only @rawstring is populated while structured fields are missing. D is incorrect because a timestamp parsing problem may cause time-related errors, but it would not by itself explain why the entire firewall event remains unparsed as raw text. CrowdStrike’s parser error docs show that parse failures are tracked separately and that @rawstring is what you inspect when events fail to parse correctly.
