Practice Free CCSE-204 CrowdStrike Certified SIEM Engineer Exam Questions Answers With Explanation

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 A . CrowdStrike LogScale documentation says the Live checkbox controls whether dashboard widget queries run as live or static queries. When enabled, the dashboard continuously updates with real-time data , which is exactly what the question asks for.

==========

The Falcon SIEM Connector requires an API client with Read access to Event Streams . This permission allows the connector to authenticate to Falcon and receive streaming event data. Other permissions such as Hosts, Incidents, or Detection Management are not the required permission for establishing Falcon event-stream ingestion.

==========

kvParse() is designed for logs that use key=value structure. It extracts the keys and values into searchable fields. parseJson() is for JSON objects, parseCsv() is for delimited positional records, and parseXml() is for XML-formatted content.

==========

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.

The correct answer is D. Prefix the field with Vendor .

CrowdStrike’s CPS documentation says that when an event contains fields that do not exist in ECS , their names should be prefixed with the string literal Vendor. . The same guidance also says to always keep the original Vendor. field when normalizing third-party fields to ECS . That directly matches option D.

Why the other options are incorrect:

CPS does not tell you to remove non-ECS fields or leave them unstructured without normalization. It also does not say every non-compliant field must be converted into ECS. Instead, the standard preserves those vendor-specific fields under the Vendor. namespace.

==========

The best answer is D. Custom role .

CrowdStrike documentation for Store app integrations states that the Falcon Administrator role is required to enable apps and plugins in the CrowdStrike Store, which is the administrative side of connector configuration. That shows connector configuration is a privileged task.

At the same time, Falcon Fusion SOAR is the workflow automation capability used to create SOAR automations in the Falcon platform. CrowdStrike describes Fusion SOAR as the workflow engine used to build and run workflows and automate actions across security processes.

Because the question specifically asks for the role that allows both actions while maintaining least privilege , the most appropriate choice is a custom role that grants only the required permissions instead of assigning a broader built-in administrative role. This is an inference from the documented permission model: connector/plugin setup requires elevated permissions, and SOAR workflow creation is a separate capability, so a narrowly scoped custom role is the least-privilege answer among the options.

Why the other options are not the best answer:

NG SIEM Analyst is intended for analyst activity, not configuration and automation administration. Falcon Security Lead is broader and not the most precise least-privilege answer. NG SIEM Security Lead may have wide SIEM access, but the question asks for the option that best maintains least privilege across both connector configuration and SOAR automation creation; that is better satisfied by a custom role . This conclusion is based on the documented need for elevated permissions for plugin configuration and the separate SOAR workflow capability.

==========

A CPS-compliant approach keeps the original Vendor field while also assigning the value to a normalized ECS field. This preserves source fidelity and enables standardized search and detections. Renaming away the original field loses source context, and storing only in @rawstring prevents structured analysis.

==========

The correct answer is C. Falcon Foundry .

CrowdStrike describes Falcon Foundry as its application development platform for building custom apps on the Falcon platform. CrowdStrike’s materials state that Falcon Foundry allows customers to quickly create their own apps, and the Foundry documentation/blog content shows it supports application logic and storage needed for custom workflows and monitoring use cases. That is exactly what fits a requirement to build an app that monitors a defined set of high-risk users and triggers alerts on suspicious activity.

Why the other options are incorrect:

Falcon QueryBuilder is for constructing queries, not building an application. Falcon Spotlight is CrowdStrike’s vulnerability management capability, not an app-development framework. Charlotte AI is an AI assistant capability, not the platform feature used to develop custom monitoring apps. The only option that matches “develop this app” is Falcon Foundry .

The sample log is a comma-delimited record with values separated by commas, and some fields are enclosed in quotes. That structure matches CSV-style parsing . In CrowdStrike LogScale, parseCsv() is used for delimited logs where fields appear in a consistent order and are separated by a defined delimiter. This fits the sample shown.

Why the other options are incorrect:

A. XML is incorrect because the log does not use XML tags.

C. JSON is incorrect because the log is not in brace-based key/value JSON format.

D. Key-Value is incorrect because the fields are not expressed as key=value pairs; they are positional comma-separated values instead.

The correct answer is B. HTTP Event Connector .

CrowdStrike describes the HTTP Event Connector (HEC) as the generic mechanism used to bring third-party data into Falcon Next-Gen SIEM when you need to onboard logs from sources that are not tied to a specific cloud-native connector. CrowdStrike’s own Next-Gen SIEM materials highlight pre-built connectors and HTTP Event Collectors as the way to extend visibility to many different third-party sources.

Because this question describes a custom internal application hosted on-prem , the cloud-specific connectors in options A , C , and D do not fit. The broad, flexible connector option intended for custom or non-native sources is the HTTP Event Connector . Also, CrowdStrike’s vCenter example shows an architecture where logs are first centralized and then onboarded to Falcon Next-Gen SIEM through an HTTP Event Connector , which aligns with this kind of custom-source pattern.

The correct answer is B . CrowdStrike LogScale documentation includes parseCEF() , parseJson() , and parseXml() as valid parsing functions. parseCEF() parses CEF-encoded messages, parseJson() parses JSON data into fields, and parseXml() parses XML content into fields.

The other options are incorrect because parseIETF() is not a valid CQL parse function in the documented parsing function set, and option D also contains malformed syntax with parseXml(.

The correct answer is B .

CrowdStrike’s Falcon LogScale Collector debug documentation says the monitor command launches a monitor terminal application and can be used to see a live view of the running state of the collector. It explicitly states that the running sources, queues and sinks can be inspected in real time . That exactly matches the question.

Why the other options are incorrect:

A can help review service logs, but it is not the documented real-time visualization command for sources and sinks.

C and D do not match the documented command for this purpose in the collector troubleshooting documentation.
