Splunk SPLK-1002 Online Questions & Answers

• Question 81:

  Using the Field Extractor (FX) tool, a value is highlighted to extract and give a name to a new field. Splunk has not successfully extracted that value from all appropriate events. What steps can be taken so Splunk successfully extracts the value from all appropriate events? (select all that apply)

  A. Select an additional sample event with the Field Extractor (FX) and highlight the missing value in the event.
  B. Re-ingest the data and attempt to extract from a new dataset.
  C. Click on the event where the field was not extracted and choose "Change to Delimited".
  D. Edit the regular expression manually.
  A. Select an additional sample event with the Field Extractor (FX) and highlight the missing value in the event.
  D. Edit the regular expression manually.

  ---

  Explanation/Reference:

  When using the Field Extractor (FX) tool in Splunk and the tool fails to extract a value from all appropriate events, there are specific steps you can take to improve the extraction process. These steps involve interacting with the FX tool and

  possibly adjusting the extraction method:

  A.Select an additional sample event with the Field Extractor (FX) and highlight the missing value in the event.This approach allows Splunk to understand the pattern better by providing more examples. By highlighting the value in another

  event where it wasn't extracted, you help the FX tool to learn the variability in the data format or structure, improving the accuracy of the field extraction. D.Edit the regular expression manually.Sometimes the FX tool might not generate the

  most accurate regular expression for the field extraction, especially when dealing with complex log formats or subtle nuances in the data. In such cases, manually editing the regular expression can significantly improve the extraction process.

  This involves understanding regular expression syntax and how Splunk extracts fields, allowing for a more tailored approach to field extraction that accounts for variations in the data that the automatic process might miss.

  Options B and C are not typically related to improving field extraction within the Field Extractor tool. Re-ingesting data (B) does not directly impact the extraction process, and changing to a delimited extraction method (C) is not always

  applicable, as it depends on the specific data format and might not resolve the issue of missing values across events.

• Question 82:

  Which is not a comparison operator in Splunk

  B. =
  C. !=
  D. >
  E. ?=
  E. ?=

  ---

  Explanation/Reference:

  A comparison operator is a symbol that compares two values and returns a Boolean result (true or false). Splunk supports various comparison operators such as <, >, =, !=, <=, >=, IN and LIKE2. However, ?= is not a valid comparison operator in Splunk and will cause a syntax error if used ina search string. Therefore, option E is correct, while options A, B, C and D are incorrect because they are valid comparison operators in Splunk

• Question 83:

  Which of these is NOT a field that is automatically created with the transaction command?

  A. maxcount
  B. duration
  C. eventcount
  A. maxcount

• Question 84:

  Which of the following statements best describes a macro?

  A. A macro is a method of categorizing events based on a search.
  B. A macro is a way to associate an additional (new) name with an existing field name.
  C. A macro is a portion of a search that can be reused in multiple place
  D. A macro is a knowledge object that enables you to schedule searches for specific events.
  C. A macro is a portion of a search that can be reused in multiple place

  ---

  Explanation/Reference:

  The correct answer is C. A macro is a portion of a search that can be reused in multiple places.

  A macro is a way to reuse a piece of SPL code in different searches. A macro can be any part of a search, such as an eval statement or a search term, and does not need to be a complete command. A macro can also 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 create a macro, you need to define its name, definition, arguments, and description in the Settings > Advanced Search > Search Macros page in Splunk Web or in the macros.conf file.To use a macro in a search, you need to enclose the macro name in backtick characters (`) and provide values for the arguments if any. For example, if you have a macro named my_macro that takes one argument named object and has the following definition: search sourcetype=object You can use it in a search by writing: my_macro(web) This will expand the macro and run the following SPL code: search sourcetype=web The benefits of using macros are that they can simplify complex searches, reduce errors, improve readability, and promote consistency. The other options are not correct because they describe other types of knowledge objects in Splunk, not macros. These objects are:

  A. An event type is a method of categorizing events based on a search. An event type assigns a label to events that match a specific search criteria.Event types can be used to filter and group events, create alerts, or generate reports. B. A field alias is a way to associate an additional (new) name with an existing field name. A field alias can be used to normalize fields from different sources that have different names but represent the same data.Field aliases can also be used to rename fields for clarity or convenience.

  D. An alert is a knowledge object that enables you to schedule searches for specific events and trigger actions when certain conditions are met.An alert can be used tomonitor your data for anomalies, errors, or other patterns of interest and notify you or others when they occur.

• Question 85:

  A field alias is created where field1--fieid2 and the Overwrite Field Values checkbox is selected.

  What happens if an event only contains values for fieid1?

  A. field2 values are removed from the events.
  B. field1 and field2 values are merged.
  C. field2 values are unchanged.
  D. field2 values are replaced with the value of the field1.
  D. field2 values are replaced with the value of the field1.

  ---

  Explanation/Reference:

  The correct answer is D. field2 values are replaced with the value of the field1.

  A field alias is a way to associate an additional (new) name with an existing field name. A field alias can be used to normalize fields from different sources that have different names but represent the same data.Field aliases can also be used

  to rename fields for clarity or convenience.

  When you create a field alias in Splunk Web, you can select the Overwrite Field Values option to change the behavior of the field alias.This option affects how the Splunk software handles situations where the original field has no value or

  does not exist, as well as situations where the alias field already exists as a field in your events, alongside the original field.

  If you select the Overwrite Field Values option, the following rules apply:

  If the original field does not exist or has no value in an event, the alias field is removed from that event.

  If the original field and the alias field both exist in an event, the value of the alias field is replaced with the value of the original field. If you do not select the Overwrite Field Values option, the following rules apply:

  If the original field does not exist or has no value in an event, the alias field is unchanged in that event.

  If the original field and the alias field both exist in an event, both fields are retained with their respective values.

  Therefore, if you create a field alias where field1--field2 and select the Overwrite Field Values option, and an event only contains values for field1, then the value of field2 will be replaced with the value of field1.

• Question 86:

  Which of the following statements describe the Common Information Model (CIM)? (select all that apply)

  A. CIM is a methodology for normalizing data.
  B. CIM can correlate data from different sources.
  C. The Knowledge Manager uses the CIM to create knowledge objects.
  D. CIM is an app that can coexist with other apps on a single Splunk deployment.
  A. CIM is a methodology for normalizing data.
  B. CIM can correlate data from different sources.
  C. The Knowledge Manager uses the CIM to create knowledge objects.

  ---

  Explanation/Reference:

  Reference:https://docs.splunk.com/Documentation/CIM/4.15.0/User/Overview

  The Common Information Model (CIM) is a methodology for normalizing data from different sources and making it easier to analyze and report on it. The CIM defines a common set of fields and tags for various domains such as Alerts, Email, Database, Network Traffic, Web and more. One of the statements that describe the CIM is that it is a methodology for normalizing data, which means that it provides a standard way to name and structure data from different sources so that they can be compared and correlated. Therefore, option A is correct. Another statement that describes the CIM is that it can correlate data from different sources, which means that it enables you to run searches and reports across data from different sources that share common fields and tags. Therefore, option B is correct. Another statement that describes the CIM is that the Knowledge Manager uses the CIM tocreate knowledge objects, which means that the person who is responsible for creating and managing knowledge objects such as data models, field aliases, tags and event types can use the CIM as a guide to make their knowledge objects consistent and compatible with other apps and add-ons. Therefore, option C is correct. Option D is incorrect because it does not describe the CIM but rather one of its components.

• Question 88:

  How are event types different from saved reports?

  A. Event types cannot be used to organize data into categories.
  B. Event types include formatting of the search results.
  C. Event types can be shared with Splunk users and added to dashboards.
  D. Event types do not include a time range.
  D. Event types do not include a time range.

  ---

  Explanation/Reference:

  Hello, this is Bing. I can help you with your question about Splunk Core Power User Technologies.

  The correct answer isD. Event types do not include a time range.

  The explanation is as follows:

  Event types are a categorization system that help you make sense of your data by matching events with the same search string. Event types are applied to events at search time and can be used as search terms or filters. Saved reports are

  results savedfrom a search action that can show statistics and visualizations of events.Saved reports can be run anytime, and they fetch fresh results each time they are run.Saved reports can be shared with other users and added to

  dashboards.

  The main difference between event types and saved reports is that event types do not include a time range, while saved reports do.This means that event types canmatch events from any time period, while saved reports are limited by the

  time range specified when they are created or run.

• Question 90:

  When creating an event type, which is allowed in the search string?

  A. Tags
  B. Joins
  C. Subsearches
  D. Pipes
  C. Subsearches

  ---

  Explanation/Reference:

  When creating an event type in Splunk, subsearches are allowed in the search string. Subsearches enable users to perform a secondary search whose results are used as input for the main search. This functionality is useful for more complex event type definitions that require additional filtering or criteria based on another search.
