Splunk SPLK-1002 Online Questions & Answers

• Question 41:

  When performing a regular expression (regex) field extraction using the Field Extractor (FX), what happens when the require option is used?

  A. The regex can no longer be edited.
  B. The field being extracted will be required for all future events.
  C. The events without the required field will not display in searches.
  D. Only events with the required string will be included in the extraction.
  D. Only events with the required string will be included in the extraction.

  ---

  Explanation

  The Field Extractor (FX) allows you to use regular expressions (regex) to extract fields from your events using a graphical interface or by manually editing the regex. When you use the FX to perform a regex field extraction, you can use the require option to specify a string that must be present in an event for it to be included in the extraction. This way, you can filter out events that do not contain the required string and focus on the events that are relevant for your extractio 2.

  Therefore, option D is correct, while options A, B and C are incorrect.

• Question 42:

  Which tool uses data models to generate reports and dashboard panels without using SPL?

  A. Visualization tab
  B. Pivot
  C. Datasets
  D. splunk CIM
  B. Pivot

  ---

  Explanation

  The correct answer is B. Pivot.

  In Splunk, Pivot is a tool that uses data models to generate reports and dashboard panels without the need for users to write or understand Splunk's Search Processing Language (SPL). Data models enable users of Pivot to create compelling reports and dashboards. When a Pivot user designs a pivot report, they select the data model that represents the category of event data that they want to work with. Then they select a dataset within that data model that represents the specific dataset on which they want to report. This makes Pivot a powerful tool for users who need to create visualizations but do not have a deep understanding of SPL.

• Question 43:

  If a search returns ____________ it can be viewed as a chart.

  A. timestamps
  B. statistics
  C. events
  D. keywords
  B. statistics

  ---

  Explanation

  If a search returns statistics, it can be viewed as a chart. Statistics are tabular data that show the relationship between two or more fields. You can create statistics by using commands such as stats, chart or timechart.

  You can view statistics as a chart by selecting the Visualization tab in the Search app and choosing a chart type such as column, line or pie. Therefore, option B is correct, while options A, C and D are incorrect because they are not types of data that can be viewed as a chart.

• Question 44:

  These allow you to categorize events based on search terms.

  Select your answer.

  A. Groups
  B. Event Types
  C. Macros
  D. Tags
  B. Event Types

• Question 45:

  The transaction command allows you to __________ events across multiple sources

  A. duplicate
  B. correlate
  C. persist
  D. tag
  B. correlate

  ---

  Explanation

  The transaction command allows you to correlate events across multiple sources. The transaction command is a search command that allows you to group events into transactions based on some common characteristics, such as fields, time, or both. A transaction is a group of events that share one or more fields that relate them to each other. A transaction can span across multiple sources or sourcetypes that have different formats or structures of data. The transaction command can help you correlate events across multiple sources by using the common fields as the basis for grouping. The transaction command can also create some additional fields for each transaction, such as duration, eventcount, startime, etc.

• Question 46:

  In which of the following scenarios is an event type more effective than a saved search?

  A. When a search should always include the same time range.
  B. When a search needs to be added to other users' dashboards.
  C. When the search string needs to be used in future searches.
  D. When formatting needs to be included with the search string.
  C. When the search string needs to be used in future searches.

• Question 47:

  Why would the following search produce multiple transactions instead of one?

  

  A. The maxspan option is not included.
  B. The transaction command has a limit of 1000 events per transaction.
  C. The transaction and commands cannot be used together.
  D. The stats list () function is used.
  A. The maxspan option is not included.

  ---

  Explanation

  In Splunk, the transaction command is used to group events that share common characteristics into a single transaction.By default, the transaction command groups all matching events into a single transaction.

  However, you can use the maxspan option to limit the time span of the transactions.If the time span between the first and last event in a transaction exceeds the maxspan value, the transaction command will start a new transaction. Therefore, if the maxspan option is not included in the search, the transaction command might produce multiple transactions instead of one if the time span between the first and last event in a transaction exceeds the default maxspan value. Here is an example of how you can use the maxspan option in a search:

  index=main sourcetype=access_combined | transaction some uniqefield maxspan=1h In this search, the transaction command groups events that share the same some uniqe fieldvalue into a single transaction, but only if the time span between the first and last event in the transaction does not exceed 1 hour.If the time span exceeds 1 hour, the transaction command will start a new transaction.

• Question 48:

  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

  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 49:

  Which knowledge object is used to normalize field names to comply with the Splunk Common Information Model (CIM)?

  A. Field alias
  B. Event types
  C. Search workflow action
  D. Tags
  A. Field alias

  ---

  Explanation

  The correct answer is A. Field alias.

  In Splunk, a field alias is a knowledge object that you can use to assign an alternate name to a field.This can be particularly useful when you want to normalize your data to comply with the Splunk Common Information Model (CIM). The CIM provides a methodology for normalizing values to a common field name.It acts as a search-time schema to define relationships in the event data while leaving the raw machine data intact.By using field aliases, you can map vendor fields to common fields that are the same for each data source in a given domain.This allows you to correlate events from different source types by normalizing these different occurrences to a common structure and naming convention.

• Question 50:

  When creating a Search workflow action, which field is required?

  A. Search string
  B. Data model name
  C. Permission setting
  D. An eval statement
  A. Search string
