Splunk Splunk Certifications SPLK-1004 Questions & Answers

• Question 31:

  What happens to panels with post-processing searches when their base search Is refreshed?

  A. The parcels are deleted.

  B. The panels are only refreshed If they have also been configured.

  C. The panels are refreshed automatically.

  D. Nothing happens to the panels.

  Correct Answer: C

  When the base search of a dashboard panel with post-processing searches is refreshed, the panels with these post-processing searches are refreshed automatically (Option C). Post-processing searches inherit the scope and results of the base search, and when the base search is updated or rerun, the post-processed results are recalculated to reflect the latest data.

• Question 32:

  When possible, what is the best choice for summarizing data to improve search performance?

  A. Us the fieldsummary command.

  B. Data model acceleration

  C. Report acceleration

  D. Summary indexing

  Correct Answer: D

• Question 33:

  What is the recommended way to create a field extraction that is both persistent and precise?

  A. Use the rex command.

  B. Use the Field Extractor and manually edit the generated regular expression.

  C. Use the Field Extractor and let it automatically generate a regular expression.

  D. Use the erex command.

  Correct Answer: B

• Question 34:

  Where can wildcards be used in the tstats command?

  A. No wildcards can be used with

  B. In the where to clause.

  C. In the from clause.

  D. In the by clause.

  Correct Answer: C

  Wildcards can be used in the from clause of the tstats command in Splunk (Option C). The from clause specifies the data model or dataset from which to retrieve the statistics, and using wildcards here allows users to query across multiple data models or datasets that share a common naming pattern, making the search more flexible and encompassing.

• Question 35:

  Which command processes a template for a set of related fields?

  A. bin

  B. xyseries

  C. foreach

  D. untable

  Correct Answer: C

  The foreach command in Splunk is used to apply a processing step to each field in a set of related fields, making it ideal for performing repetitive tasks across multiple fields without having to specify each field individually. This command can process a template of commands or functions to apply to each specified field, thereby streamlining operations that need to be applied uniformly across multiple data points.

• Question 36:

  Which commands can run on both search heads and indexers?

  A. Transforming commands

  B. Centralized streaming commands

  C. Dataset processing commands

  D. Distributable streaming commands

  Correct Answer: D

  Distributable streaming commands in Splunk can run on both search heads and indexers (Option D). These commands operate on each event independently and can be distributed across indexers for parallel execution, which enhances search efficiency and scalability. This category includes commands like search, where, eval, and many others that do not require the entire dataset to be available to produce their output.

• Question 37:

  How can the erex and rex commands be used in conjunction to extract fields?

  A. The regex Generated by the erex command can be edited and used with the regex command in a subsequent search.

  B. The regex generated by the rex command can be edited and used with the erex command in a subsequent search.

  C. The regex generated by the erex command can be edited and used with the erex command in a subsequent search.

  D. The erex and rex commands cannot be used in conjunction under any circumstances.

  Correct Answer: A

  The erex command in Splunk is used to generate regular expressions based on example data, and these generated regular expressions can then be edited and utilized with the rex command in subsequent searches (Option A). The erex command is helpful for users who may not be familiar with regular expression syntax, as it provides a starting point that can be refined and customized with rex for more precise field extraction.

• Question 38:

  Which search generates a field with a value of "hello"?

  A. | Makeresults field-`'hello''

  B. | Makeresults | fields`'hello''

  C. | Makeresults | eval field-`'hello''

  D. | Makeresults | eval field =make{''hello''}

  Correct Answer: C

  To generate a field with a value of "hello" using the makeresults command in Splunk, the correct syntax is | makeresults | eval field="hello" (Option C). The makeresults command creates a single event, and the eval command is used to add a new field (named "field" in this case) with the specified value ("hello"). This is a common method for creating sample data or for demonstration purposes within Splunk searches.

• Question 39:

  When using the bin command, which argument sets the bin size?

  A. mazDataSizeMB

  B. max

  C. volume

  D. span

  Correct Answer: D

  When using the bin command in Splunk, the span argument is used to set the size of each bin (Option D). The span argument determines the granularity or width of each bin when segmenting data over a time range or numerical field, which is essential for time series analysis, histogram generation, or other aggregated data visualizations.

• Question 40:

  Which of the following functions' primary purpose is to convert epoch time to a string format?

  A. tostring

  B. strptime

  C. tonumber

  D. strftime

  Correct Answer: D

  The strftime function in Splunk is used to convert epoch time (also known as POSIX time or Unix time, which is a system for describing points in time as the number of seconds elapsed since January 1, 1970) into a human-readable string format. This function is particularly useful when formatting timestamps in search results or when creating more readable time representations in dashboards and reports. The strftime function takes an epoch time value and a format string asarguments and returns the formatted time as a string according to the specified format. The other options (tostring, strptime, and tonumber) serve different purposes: tostring converts values to strings, strptime converts string representations of time into epoch format, and tonumber converts values to numbers.
