CCSE-204 Questions and Answers

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.

The correct answer is A. Full .

CrowdStrike’s Falcon LogScale Collector Fleet Management enrollment documentation states that the enrollment mode can be full or localConfig , and it specifically defines full as the mode that enrolls the collector into Fleet Management with the configuration of log sources stored and managed centrally in LogScale/Next-Gen SIEM.

Why the other options are incorrect:

B. Complete and C. Central are not documented enrollment mode names. D. localConfig is a valid mode, but CrowdStrike says that mode keeps the log source configuration managed and stored locally on the host , not centrally.

The correct answer is C. NGSIEM with both read and write permissions .

CrowdStrike integration guidance for querying Next-Gen SIEM event data states that the API client needs the NGSIEM scope with both Read and Write permissions . The documentation explains why: Write is required to create the search/query job, and Read is required to retrieve the query results.

Why the other options are incorrect:

A is incorrect because the documented requirement is Read + Write ; there is no documented “execute” permission in the cited guidance. B is incorrect because read-only access would let you read results but not create the query job. D is incorrect because write-only access would let you submit the job but not read the results back.

==========

The correct answer is A . CrowdStrike documentation states that when a timestamp does not include timezone information, or when you need to control timezone interpretation, you should pass the timezone parameter to parseTimestamp() or findTimestamp(). Since parsers are where ingest-time transformations are defined, the correct engineering approach is to create or clone a custom parser for that log source and explicitly apply the needed timezone handling there. CrowdStrike’s custom parser docs explain that parsers are used to control how incoming events are transformed during ingest, and the timestamp parsing docs explain that timezone can be set directly in the parser logic.

Why the other options are incorrect:

B is not the documented parser-side solution. While changing the source may work operationally in some environments, CrowdStrike’s parsing guidance focuses on fixing time interpretation in the parser by using timezone or related timestamp parsing controls. C is incorrect because changing the timestamp field name does not solve timezone parsing. D is incorrect because dropping the source timestamp and relying on ingest time would lose the original event time, which is exactly what parsers are meant to preserve by converting source timestamps into @timestamp. CrowdStrike explicitly states that one of the most important jobs of a parser is assigning correct timestamps to events.

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.

The correct answer is B. sudo logscale-collector enroll < TOKEN > .

Current CrowdStrike LogScale Collector documentation shows the enrollment command using the logscale-collector binary. For example, the macOS custom installation page explicitly shows:

sudo logscale-collector enroll enrolltoken

The Fleet Management enrollment documentation also explains that you copy the enrollment command from the UI and run it on the machine hosting the collector.

Why the other options are incorrect:

A is a Windows path, not Linux. C reflects the older humio-log-collector naming that existed in earlier versions and release history, but the current docs use logscale-collector for the enrollment command. D does not match the documented command syntax. CrowdStrike’s current documentation centers the enrollment workflow on logscale-collector enroll < token > .

==========

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.

==========

The correct answer is C. #observer.type and #event.kind .

CrowdStrike’s CPS migration documentation lists the CPS-compliant parser tags, including #event.dataset , #event.kind , #event.module , and #observer.type . Since both #observer.type and #event.kind are explicitly listed, option C is the correct pair.

Why the other options are incorrect:

The documentation lists #Vendor as a tag, not #vendor.name , and it does not list #event.type among the CPS parser tags in the tag list. That makes options A, B, and D incorrect.

The groupBy() function is used to aggregate events by one or more fields, such as hostname, and return counts or other aggregate calculations. table() displays selected fields but does not perform grouped aggregation. parseJson() and kvParse() are parsing functions, not aggregation functions.

==========

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 .
