Splunk SPLK-1002 - Splunk Core Certified Power User Exam

The correct answer is B. Reusable pieces of search processing language.

The explanation is as follows:

Search macros are knowledge objects that allow you to insert chunks of SPL into other searches12.

Search macros can be any part of a search, such as an eval statement or a search term, and do not need to be a complete command12.

You can also specify whether the macro field takes any arguments and define validation expressions for them12.

Search macros can help you make your SPL searches shorter and easier to understand3.

To use a search macro in a search string, you need to put a backtick character () before and after the macro name[^1^][1]. For example, mymacro`.

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 maxspan function of the transaction command allows you to set the maximum total time between the earliest and latest events returned. The maxspan function is an argument that can be used with the transaction command to specify the start and end constraints for the transactions. The maxspan function takes a time modifier as its value, such as 30s, 5m, 1h, etc. The maxspan function sets the maximum time span between the first and last events in a transaction. If the time span between the first and last events exceeds the maxspan value, the transaction will be split into multiple transactions.

When defining a search macro, the required elements are the name and the definition of the macro. The name is a unique identifier for the macro that can be used to invoke it in other searches. The definition is the search string that the macro expands to when referenced. The arguments, validation expression, and validation error message are optional elements that can be used to customize the macro behavior and input validation2
