CCFR-201 Online Practice Questions and Answers

Correct Answer: C

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, there are three ways to export process event data from a detection in .CSV format1:

You can use the Process Timeline tool and click on "Export CSV" button at the top right corner1.

You can use the Event Search tool and select one or more events and click on "Export CSV" button at the top right corner1.

You can use the Full Detection Details tool and choose the "View Process Activity" option from any process node in the process tree view1. This will show you all events generated bythat process in a rows-and-columns style view1. You can

then click on "Export CSV" button at the top right corner1.

Correct Answer: B

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, Global Prevalence and Local Prevalence are two fields that provide information about how common or rare a file is based on its hash value2. Global Prevalence tells you how frequently the hash of the triggering file is seen across all CrowdStrike customer environments2. Local Prevalence tells you how frequently the hash of the triggering file is seen within your environment (CID)2. These fields can help you assess the risk and impact of a detection2.

Correct Answer: A

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Process Timeline tool allows you to view all cloudable events associated with a given process, such as process creation, network connections, file writes, registry modifications, etc2. You can also filter the events by various criteria, such as event type, timestamp range, file name, registry key, network destination, etc2. This is an advantage of using the Process Timeline tool because it allows you to focus on specific events that are relevant to your investigation2.

Correct Answer: B

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Hash Execution Search tool allows you to search for one or more SHA256 hashes and view a summary of information from Falcon events that contain those hashes1. The summary includes the hostname, sensor ID, OS, country, city, ISP, ASN, and geolocation of the host that loaded or executed those hashes1. You can also see a count of detections and incidents related to those hashes1.

Correct Answer: B

According to the CrowdStrike Falcon?Data Replicator (FDR) Add-on for Splunk Guide, the Full Detection Details tool allows you to view detailed information about a detection, such as detection ID, severity, tactic, technique, description, etc1. You can also view the events generated by the processes involved in the detection in different ways, such as process tree, process timeline, or process activity1. The process tree view provides a graphical representation of the process hierarchy and activity1. You can see children and sibling processes information by expanding or collapsing nodes in the tree1.

Correct Answer: C

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, Reduced Functionality Mode (RFM) is a state where a host's sensor has limited functionality due to various reasons, such as license expiration, network issues, tampering attempts, etc1. You can find hosts that are in RFM by using the Host Search tool and filtering by Sensor Status = RFM1. You can also view details about why a host is in RFM by clicking on its hostname1.

Correct Answer: D

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Hash Search tool allows you to search for one or more SHA256 hashes and view a summary of information from Falcon events that contain those hashes1. The summary includes the hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that loaded or executed those hashes1. You can also see a count of detections and incidents related to those hashes1. The primary purpose for running a Hash Search is to review information surrounding a hash's related activity, such as which hosts and processes were involved, where they were located, and whether they triggered any alerts1.

Correct Answer: A

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Event Search tool allows you to search for events based on various criteria, such as event type, timestamp, hostname, IP address, etc1. You can also select one or more events and perform various actions, such as show a process timeline, show a host timeline, show associated event data, show a +/- 10-minute window of events, etc1. However, there is no option to draw a process explorer, which is a graphical representation of the process hierarchy and activity1.

Correct Answer: D

According to the CrowdStrike Falcon?Data Replicator (FDR) Add-on for Splunk Guide, the allowlist feature allows you to exclude files or directories from being scanned or blocked by CrowdStrike's machine learning engine or indicators of attack (IOAs)2. This can reduce false positives and improve performance2. When you allowlist a hash, you are allowing that file to execute on any host that belongs to your organization's CID (customer ID)2. This does not affect other Falcon customers or hosts outside your CID2.

Correct Answer: A

According to the CrowdStrike Falcon?Data Replicator (FDR) Add-on for Splunk Guide, detection data is stored in the CrowdStrike Cloud for 90 days before purging begins2. This means that you can access and view detections from the past 90 days using the Falcon platform or API2. If you want to retain detection data for longer than 90 days, you can use FDR to replicate it to your own storage system2.
