Important CrowdStrike CCFR-201b Exam Questions

Answer: A

Explanation:

According to theCrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the IP Search tool allows you to search for an IP address and view a summary of information from Falcon events that contain that IP address1.The summary includes the hostname, sensor ID, OS, country, city, ISP, ASN, and geolocation of the host that communicated with that IP address1.

Answer: B

Explanation:

According to theCrowdStrike 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.

Answer: A

Explanation:

According to the [CrowdStrike website], the Discover page is where you can search for and analyze various types of indicators of compromise (IOCs), such as hashes, IP addresses, or domains that are associated with malicious activities. You can use various tools, such as Hash Executions, IP Addresses, Remote or Network Logon Activity, etc., to perform different types of searches and view the results in different ways. If you want to search for any activity related to an IP address that was compromised by a third-party vendor, you can use the IP Addresses tool to do so. You can input the IP address and see a summary of information from Falcon events that contain that IP address, such as hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that communicated with that IP address.

Answer: B

Explanation:

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the process tree view provides a visualization of program ancestry, which shows the parent-child and sibling relationships among the processes1.You can also see the event types and timestamps for each process1.The processes on the same plane are ordered by time started in descending order, meaning that the most recent process is at the bottom and the oldest process is at the top1.For example, in the image you sent me, CMD.EXE is the oldest process and VMTOOLSD.EXE is the most recent process on that plane1.

Answer: A

Explanation:

According to theCrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, IOC Management allows you to manage indicators of compromise (IOCs), which are artifacts such as hashes, IP addresses, or domains that are associated with malicious activities2.You can set different actions for IOCs, such as Allow, No Action, or Always Block2.When you set a hash to Always Block through IOC Management, you are preventing that file from executing on any host in your organization by default2.This action also generates a detection alert when the file is blocked2.
