Free Practice Questions for Splunk SPLK-1002 Exam

The fillnull command 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. The fillnull 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.

A workflow action is a link that appears when you click an event field value in your search results1. A workflow action can open a web page or run another search based on the field value1. There are two types of workflow actions: GET and POST1. A GET workflow action appends the field value to the end of a URI and opens it in a web browser1. A POST workflow action sends the field value as part of an HTTP request to a web server1. You can configure a workflow action to open a web page in either the same window or a new window1. Therefore, option D is correct, while options A, B and C are incorrect.

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.

The correct answer is D. An argument can be passed to the inner macro by nesting parentheses.

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

To pass an argument to the inner macro, you need to use parentheses to enclose the argument value and separate it from the outer macro argument. For example, if you have a search macro named outer_macro (1) that contains another search macro named inner_macro (2), and both macros take one argument each, you can pass an argument to the inner macro by using the following syntax:

outer_macro (argument1, inner_macro (argument2))

This will replace the argument1 and argument2 with the values you provide in the search string. For example, if you want to pass “foo” as the argument1 and “bar” as the argument2, you can write:

outer_macro ("foo", inner_macro ("bar"))

This will expand the macros with the corresponding arguments and run the SPL code contained in them.

A calculated field in Splunk is created using an eval expression, which allows users to perform calculations or transformations on field values during search time.

Event types are based on simple search strings and cannot contain pipes (|) or subsearches .

Extract: “Event type search strings must not contain a pipe (|) and cannot include subsearches or transforming commands.”

Only option D is a valid base search that can be saved as an event type.
