• Question 191:

  The Splunk Common Information Model (CIM) is a collection of what type of knowledge object?

  A. KV Store
  B. Lookups
  C. Saved searches
  D. Data models
  D. Data models

  ---

  Explanation/Reference:

  The Splunk Common Information Model (CIM) is a collection of data models that apply a common structure and naming convention to data from any source. A data model is a type of knowledge object that defines the structure and relationships of fields in a dataset. A datamodel can have one or more datasets, which are subsets of the data model that represent different aspects of the data. For example, the Network Traffic data model has datasets such as All Traffic, DNS, HTTP, etc. The CIM contains 28 pre-configured data models that cover various domains such as authentication, network traffic, web, email, etc. The CIM is implemented as an add-on that contains the JSON files for the data models, documentation, and tools that support the consistent, normalized treatment of data for maximum efficiency at search time.

• Question 192:

  The Field Extractor (FX) is used to extract a custom field. A report can be created using this custom field. The created report can then be shared with other people in the organization. If another person in the organization runs the shared report and no results are returned, why might this be? (select all that apply)

  A. Fast mode is enabled.
  B. The dashboard is private.
  C. The extraction is private-
  D. The person in the organization running the report does not have access to the index.
  C. The extraction is private-
  D. The person in the organization running the report does not have access to the index.

  ---

  Explanation/Reference:

  The Field Extractor (FX) is a tool that helps you extract fields from your events using a graphical interface. You can create a report using a custom field extracted by the FX and share it with other users in your organization. However, if another user runs the shared report and no results are returned, there could be two possible reasons. One reason is that the extraction is private, which means that only you can see and use the extracted field. To make the extraction available to other users, you need to make it global or app-level. Therefore, option C is correct. Another reason is that the other user does not have access to the index where the events are stored. To fix this issue, you need to grant the appropriate permissions to the other user for the index. Therefore, option D is correct. Options A and B are incorrect because they are not related to the field extraction or the report.

• Question 193:

  What does the Splunk Common Information Model (CIM) add-on include? (select all that apply)

  A. Custom visualizations
  B. Pre-configured data models
  C. Fields and event category tags
  D. Automatic data model acceleration
  B. Pre-configured data models
  C. Fields and event category tags

  ---

  Explanation/Reference:

  The Splunk Common Information Model (CIM) add-on is a collection of pre- built data models and knowledge objects that help you normalize your data from different sources and make it easier to analyze and report on it. The CIM add-on includes pre-configured data models that cover various domains such as Alerts, Email, Database, Network Traffic, Web and more. Therefore, option B is correct. The CIM add-on also includes fields and event category tags that define the common attributes and labels for the data models. Therefore, option C is correct. The CIM add-on does not include custom visualizations or automatic data model acceleration. Therefore, options A and D are incorrect.

• Question 194:

  A space is an implied _____ in a search string.

  A. OR
  B. AND
  C. ()
  D. NOT
  B. AND

  ---

  Explanation/Reference:

  A space is an implied AND in a search string, which means that it acts as a logical operator that returns events that match both terms on either side of the space. For example, status=200 method=GET will return events that have both status=200 and method=GET. Therefore, option B is correct, while options A, C and D are incorrect because they are not implied by a space in a search string.

• Question 195:

  How is an event type created from the search window? (select all that apply) A. In the top right corner, click Save As > Event Type.

  B. In an event's detail dropdown, click Event Actions > Build Event Type.
  C. Edit eventtypes.conf and add a new stanza.
  D. Add | eventtype to the SPL and execute the search.
  C. Edit eventtypes.conf and add a new stanza.

  ---

  Explanation/Reference:

  In Splunk, you can create an event type from the search window by running a search that would make a good event type, then clicking Save As and selecting Event Type. This opens the Save as Event Type dialog, where you can provide the

  event type name and optionally apply tags to it.

  You can also create an event type by editing the event types.conf file and adding a new stanza. Each stanza in the event types.conf file represents an event type. The stanza name is the name of the event type, and the search attribute

  specifies the search string that defines the event type.

  It's important to note that while you can use the event type command in a search to find events associated with a specific event type, adding | event type to the SPL and executing the search does not create a new event type. Similarly,

  clicking Event Actions > Build Event Type in an event's detail dropdown does not create a new event type.

• Question 196:

  How is a macro referenced in a search?

  A. By using the macroname command.
  B. By using the macro command.
  C. By enclosing the macro name in backtick characters (`).
  D. By enclosing the macro name in single-quote characters (`).
  C. By enclosing the macro name in backtick characters (`).

  ---

  Explanation/Reference:

  The correct answer is C. By enclosing the macro name in backtick characters (`).

  A macro is a way to reuse a piece of SPL code in different searches. A macro can take arguments, which are variables that can be replaced by different values when the macro is called. A macro can also contain another macro within it,

  which is called a nested macro. To reference a macro in a search, you need to enclose the macro name in backtick characters (). For example, if you have a macro namedmy_macro` that takes one argument, you can reference it in a search

  by using the following syntax:

  |my_macro(argument)| ...

  This will replace the macro name and argument with the SPL code contained in the macro definition. For example, if the macro definition is:

  [my_macro(argument)] search sourcetype=$argument$ And you reference it in a search with:

  index=main |my_macro(web)| stats count by host

  This will expand the macro and run the following SPL code:

  index=main | search sourcetype=web | stats count by host References:

  Use search macros in searches

• Question 197:

  What is the purpose of the fillnull command?

  A. Replace empty values with a specified value.
  B. Create a new field based on the values in an existing field.
  C. Rename a specific field in the search results.
  D. Replace all values in a specific field with a default value.
  A. Replace empty values with a specified value.

  ---

  Explanation/Reference:

  Thefillnullcommand in Splunk is used to handle missing data within search results. It plays a crucial role in data normalization and preparation, especially before performing statistical analyses or visualizations. A.Replace empty values with a specified value:This is the correct answer. Thefillnull command is specifically designed to replace null values (empty values) with a specified default value. This is particularly useful in ensuring consistency within your data, especially when performing operations that require numerical values or when you want to distinguish between genuinely missing data and zeroes, for instance. Example Usage:... | fillnull value=0 This command would replace all null values in the search results with 0.

• Question 198:

  What does the transaction command do?

  A. Groups a set of transactions based on time.
  B. Creates a single event from a group of events.
  C. Separates two events based on one or more values.
  D. Returns the number of credit card transactions found in the event logs.
  B. Creates a single event from a group of events.

  ---

  Explanation/Reference:

  The transaction command is a search command that creates a single event from a group of events that share some common characteristics. The transaction command can group events based on fields, time, or both. The transaction command can also create some additional fields for each transaction, such as duration, eventcount, startime, etc. The transaction command does not group a set of transactions based on time, but rather groups a set of events into a transaction based on time. The transaction command does not separate two events based on one or more values, but rather joins multiple events based on one or more values. The transaction command does not return the number of credit card transactions found in the event logs, but rather creates transactions from the events that match the search criteria.

• Question 199:

  In this search, __________ will appear on the y-axis. SEARCH: sourcetype=access_combined status!=200 | chart count over host

  A. status
  B. host
  C. count
  C. count

  ---

  Explanation/Reference:

  In this search, count will appear on the y-axis. This search uses the chart command to create a chart of the count of events over host for events that have status not equal to 2002. The chart command creates a table with one column for each value of the field after the over clause and one row for each value of the field after the by clause (if any). The values in the table are calculated by applying the function before the over clause to the events in each group. In this case, the chart command creates a table with one column for each host and one row for the count of events for each host. The y-axis of the chart shows the values of the count function applied to each host. Therefore, option C is correct, while options A and B are incorrect because they appear on the x-axis or as labels of the chart.

• Question 200:

  What does the fillnull command replace null values with, if the value argument is not specified?

  B. N/A
  C. NaN
  D. NULL
  A

  ---

  Explanation/Reference:

  The fillnull command replaces null values with 0 by default, if the value argument is not specified. You can use the value argument to specify a different value to replace null values with, such as N/A or NULL.
