Answer: A
Explanation:
ContextTimeStamp_decimal is the field that shows the system time of the event that triggered the
sensor to send data to the cloud. In this case, it would be the time when the file was written.
FileTimeStamp_decimal is the field that shows the last modified time of the file, which may not be the
same as the time when the file was written. ProcessStartTime_decimal is the field that shows the start
time of the process that performed the file write operation, which may not be the same as the time
when the file was written. Timestamp is the field that shows the time when the sensor data was
received by the cloud, which may not be the same as the time when the file was written.

2.Which of the following is the proper method to quantify search results, enabling a hunter to quickly
sort and identify outliers?
A. Using the "| stats count by" command at the end of a search string in Event Search
B. Using the "|stats count" command at the end of a search string in Event Search
C. Using the "|eval" command at the end of a search string in Event Search
D. Exporting Event Search results to a spreadsheet and aggregating the results
Answer: A
Explanation:
This is the proper method to quantify search results, enabling a hunter to quickly sort and identify
outliers. The stats command is used to calculate summary statistics on the results of a search or
subsearch, such as count, sum, average, etc. The count by option is used to count the number of
events for each distinct value of a field or fields and display them in a table. This can help find rare or
common values that could indicate anomalies or deviations from normal behavior.
Reference: https://docs.splunk.com/Documentation/Splunk/8.2.3/SearchReference/Stats
3.To find events that are outliers inside a network,___________is the best hunting method to use.
A. time-based
B. machine learning
C. searching
D. stacking
Answer: D
Explanation:
Stacking (Frequency Analysis) is the best hunting method to use to find events that are outliers inside
a network. Stacking involves grouping events by a common attribute and counting their frequency,
then sorting them by ascending or descending order to identify rare or common events. This can help
find anomalies or deviations from normal behavior that could indicate malicious activity. Time-based
searching, machine learning, and searching are not specific hunting methods to find outliers.

4.While you're reviewing Unresolved Detections in the Host Search page, you notice the User Name
column contains "hostnameS "
What does this User Name indicate?
A. The User Name is a System User
B. The User Name is not relevant for the dashboard
C. There is no User Name associated with the event
D. The Falcon sensor could not determine the User Name
Answer: C
 2 / 5
Explanation:
When you see “hostnameS” in the User Name column in the Host Search page, it means that there
is no User Name associated with the event. This can happen when the event is related to a system
process or service that does not have a user context. It does not mean that the User Name is a
System User, that the User Name is not relevant for the dashboard, or that the Falcon sensor could
not determine the User Name.

5.Which of the following queries will return the parent processes responsible for launching
badprogram exe?
A. [search (ParentProcess) where name=badprogranrexe ] | table ParentProcessName _time
B. event_simpleName=processrollup2 [search event_simpleName=processrollup2
FileName=badprogram.exe | rename ParentProcessld_decimal AS TargetProcessld_decimal | fields
aid TargetProcessld_decimal] | stats count by FileName _time
C. [search (ProcessList) where Name=badprogram.exe ] | search ParentProcessName | table
ParentProcessName _time
D. event_simpleName=processrollup2 [search event_simpleName=processrollup2
FileName=badprogram.exe | rename TargetProcessld_decimal AS ParentProcessld_decimal | fields
aid TargetProcessld_decimal] | stats count by FileName _time
Answer: D
Explanation:
This query will return the parent processes responsible for launching badprogram.exe by using a
subsearch to find the processrollup2 events where FileName is badprogram.exe, then renaming the
TargetProcessld_decimal field to ParentProcessld_decimal and using it as a filter for the main search,
then using stats to count the occurrences of each FileName by _time. The other queries will either not
return the parent processes or use incorrect field names or syntax.

6.Which Falcon documentation guide should you reference to hunt for anomalies related to scheduled
tasks and other Windows related artifacts?
A. Hunting and Investigation
B. Customizable Dashboards
C. MITRE-Based Falcon Detections Framework
D. Events Data Dictionary
Answer: A
Explanation:
The Hunting and Investigation guide is the Falcon documentation guide that you should reference to
hunt for anomalies related to scheduled tasks and other Windows related artifacts. The Hunting and
Investigation guide provides sample hunting queries, select walkthroughs, and best practices for
hunting with Falcon. It covers various topics such as process execution, network connections, registry
activity, scheduled tasks, and more.

7.What Search page would help a threat hunter differentiate testing, DevOPs, or general user activity
from adversary behavior?
A. Hash Search
B. IP Search
C. Domain Search
D. User Search
 3 / 5
Answer: D
Explanation:
User Search is a search page that allows a threat hunter to search for user activity across endpoints
and correlate it with other events. This can help differentiate testing, DevOPs, or general user activity
from adversary behavior by identifying anomalous or suspicious user actions, such as logging into
multiple systems, running unusual commands, or accessing sensitive files.

8.When exporting the results of the following event search, what data is saved in the exported file
(assuming Verbose Mode)?event_simpleName=*Written | stats count by ComputerName
A. The text of the query
B. The results of the Statistics tab
C. No data Results can only be exported when the "table" command is used
D. All events in the Events tab
Answer: B
Explanation:
When exporting the results of an event search, the data that is saved in the exported file depends on
the mode and the tab that is selected. In this case, the mode is Verbose and the tab is Statistics, as
indicated by the stats command. Therefore, the data that is saved in the exported file is the results of
the Statistics tab, which shows the count of events by ComputerName. The text of the query, all
events in the Events tab, and no data are not correct answers.
Reference: https://docs.splunk.com/Documentation/Splunk/8.2.3/Search/Exportsearchresults
9.What is the difference between a Host Search and a Host Timeline?
A. Host Search is used for detection investigation and Host Timeline is used for proactive hunting
B. A Host Search organizes the data in useful event categories like process executions and network
connections, a Host Timeline provides an uncategorized view of recorded events in chronological
order
C. You access a Host Search from a detection to show you every recorded process event related to
the detection and you can only populate the Host Timeline fields manually
D. There is no difference. You just get to them different ways
Answer: B
Explanation:
This is the difference between a Host Search and a Host Timeline. A Host Search is an Investigate
tool that allows you to view events by category, such as process executions, network connections, file
writes, etc. A Host Timeline is an Investigate tool that allows you to view all events in chronological
order, without any categorization. Both tools can be used for detection investigation and proactive
hunting, depending on the use case and preference. You can access a Host Search from a detection
or manually enter the host details. You can also populate the Host Timeline fields manually or from
other pages in Falcon.
