Splunk Splunk Core Certified User SPLK-1004 Questions & Answers

• Question 1:

  How is a cascading input used?

  A. As part of a dashboard, but not in a form.

  B. Without notation in the underlying. XML.

  C. As a way to filter other input selections.

  D. As a default way to delete a user role.

  Correct Answer: C

  A cascading input is used as a way to filter other input selections within a dashboard or form (Option C). It enables a dynamic user interface where the selection made in one input (e.g., a dropdown menu) determines the available options in another input. This setup allows for more intuitive and relevant user interactions, as each choice narrows down the subsequent options to ensure they are contextually appropriate.

• Question 2:

  Which of the following Is valid syntax for the split function?

  A. ...| eval split phoneNUmber by "_" as areaCodes.

  B. ...| eval areaCodes = split (phonNumber, "_"

  C. ...| eval phoneNumber split("-", 3, areaCodes)

  D. ...| eval split (phone-Number, "_", areaCodes)

  Correct Answer: B

  The valid syntax for using the split function in Splunk is ... | eval areaCodes = split(phoneNumber, "_") (Option B). The split function divides a string into an array of substrings based on a specified delimiter, in this case, an underscore. The resulting array is stored in the new field areaCodes.

• Question 3:

  Which element attribute is required for event annotation?

  A.

  B.

  C.

  D.

  Correct Answer: D

  In Splunk dashboards, event annotations are used to add informative overlays on timeline visualizations to mark significant events. The required element attribute to define an event annotation within a dashboard panel is

  (Option D). This attribute specifies that the search within this element is intended to generate annotations, which are then overlaid on the timeline based on the time and information provided by the search results.

• Question 4:

  Which of the following is an event handler action?

  A. Run an eval statement based on a user clicking a value on a form.

  B. Set a token to select a value from the time range picker.

  C. Pass a token from a drilldown to modify index settings.

  D. Cancel all jobs based on the number of search job results captured.

  Correct Answer: A

  An event handler action in Splunk is an action that is triggered based on user interaction with dashboard elements. Running an eval statement based on a user clicking a value on a form (Option A) is an example of an event handler action. This capability allows dashboards to be interactive and dynamic, responding to user inputs or actions to modify displayed data, visuals, or other elements in real-time.

• Question 5:

  Which stats function is used to return a sorted list of unique field values?

  A. values

  B. sum

  C. count

  D. list

  Correct Answer: A

  The values function in the stats command in Splunk is used to return a sorted list of unique field values (Option A). This function is particularly useful for summarizing data by listing all unique values of a specified field across the events returned by the search, which can provide insights into the diversity and distribution of the data associated with that field.

• Question 6:

  If a nested macro expands to a search string that begins with a generating command, what additional syntax is needed?

  A. Double tick marks around the nested macro.

  B. A comma before the nested macro.

  C. Square brackets around the nested macro.

  D. A pipe character before the nested macro.

  Correct Answer: C

  When a nested macro in Splunk expands to a search string that begins with a generating command, square brackets (Option C) are needed around the nested macro. This syntax ensures that the expanded macro is correctly interpreted as part of the overall search command structure. Generating commands in Splunk are those that can start a search pipeline and do not require input from a preceding command, such as search, inputlookup, and datamodel. Encapsulating the nested macro in square brackets allows Splunk to process it as an independent subsearch or command within the larger search query. The other options, including double tick marks, a comma, and a pipe character, do not provide the correct syntax for this purpose.

• Question 7:

  What is the value of base lispy in the Search Job Inspector for the search index-sales clientip-170.192.178.10?

  A. [ index::sales 192 AND 10 AMD 178 AND 170 ]

  B. [ index::sales AND 469 10 702 390 ]

  C. [ 192 AND 10 AND 178 AND 170 Index::sales ]

  D. [ AND 10 170 178 192 Index::sales ]

  Correct Answer: A

• Question 8:

  Which is a regex best practice?

  A. Use complex expressions rather than simple ones.

  B. Avoid backtracking.

  C. Use greedy operators (. *) instead of non-greedy operators (. *? ).

  D. Use * rather than +.

  Correct Answer: B

  In regex (regular expressions), one of the best practices is to avoid backtracking when possible. Backtracking occurs when the regex engine revisits previous parts of the input string to attempt different permutations of the pattern, which can significantly degrade performance, especially with complex patterns on large inputs. Designing regex patterns to minimize or avoid backtracking can lead to more efficient and faster evaluations.

• Question 9:

  If a search contains a subsearch, what is the order of execution?

  A. The order of execution depends on whether either search uses a stats command.

  B. The inner search executes first.

  C. The otter search executes first.

  D. The two searches are executed in parallel.

  Correct Answer: B

  In a Splunk search containing a subsearch, the inner subsearch executes first (Option B). The result of the subsearch is then passed to the outer search. This is because the outer search often depends on the results of the inner subsearch to complete its execution. For example, a subsearch might be used to identify a list of relevant terms or values which are then used by the outer search to filter or manipulate the main dataset.

• Question 10:

  Which of the following is not a common default time field?

  A. date_zone

  B. date minute

  C. date_year

  D. date_day

  Correct Answer: A

  In Splunk, common default time fields include date_minute, date_year, and date_day, which represent the minute, year, and day parts of event timestamps, respectively. date_zone (Option A) is not recognized as a common default time field in Splunk. The platform typically uses fields like _time and various date_* fields for time-related information but does not use date_zone as a standard time field.
